ABOUT THIS GUIDE
1 INTRODUCTION The NBX Administrator’s Guide explains how to configure your NBX® system. This chapter covers these topics: ■ Network-based Telephony ■ Overview of the System Software ■ NBX NetSet Administration Utility ■ NBX NetSet Features For information about installing hardware components, see the NBX Installation Guide. Network-based Telephony 3Com Networked Telephony Solutions merge telephony with networking by delivering business telephone service over a data network.
CHAPTER 1: INTRODUCTION The NBX system provides the reliability required in a business environment because NBX system voice traffic is independent of computer traffic on the same network. In fact, after the NCP completes the processing required to connect two telephones, the telephones communicate directly with each other. Therefore, existing conversations are not affected if power to the NCP fails.
Overview of the System Software 21 Redialing From Call Logs In the NBX Business Telephone and NBX Basic Telephone display panels, you can view logs of recent Missed Calls, Answered Calls, and Dialed Calls. You can select and redial a call from any of these lists, as well as from the directory of internal users, your personal speed dial list, or the system-wide speed dial list.
CHAPTER 1: INTRODUCTION NBX NetSet Administration Utility The NBX NetSet Administration utility is an HTML-based web interface in which you configure and manage the NBX system. You need Microsoft Internet Explorer (version 5.5 or later is optimal) to administer the system. (You do not need Internet access.) Figure 1 shows the NBX NetSet - Main Menu window, which appears when you log on to the NBX NetSet utility.
NBX NetSet Features NBX NetSet Features 23 Table 4 describes the features that administrators can access through the NBX NetSet - Main Menu window. Table 4 NBX NetSet Features for the NBX Administrator Icon Description Configure and manage system-wide NBX Voice Messaging, Auto Attendants, and VPIM settings. If you install a license for a third-party messaging application and disable NBX Messaging, this icon is not available.
CHAPTER 1: INTRODUCTION Table 4 NBX NetSet Features (continued)for the NBX Administrator Icon Description Configure and manage these system-level operations: ■ Upgrading software ■ Rebooting and shutting down the NBX system ■ Managing data (database backup and restore) ■ Viewing and managing event log files ■ Viewing and adding licenses for optional features ■ Setting regionally different information (voice-prompt language, dial tones and cadences, and documentation language) ■ Installing
NBX NetSet Features 25 Table 5 describes the additional icons that appear on or below the NBX NetSet - Main Menu window. They are shortcuts to specific areas within the NBX NetSet utility and to some of the online documentation. Table 5 NBX NetSet Shortcuts Icon Description The Help icon in the NBX NetSet - Main Menu window provides access to the Contents, Index, and search features of the online Help system.
CHAPTER 1: INTRODUCTION
2 DIAL PLAN The NBX system’s dial plan determines how the system handles calls. It defines the set of destinations that the system can reach, how to get to these destinations, and which telephone numbers to dial to reach these destinations. This chapter provides information about understanding, developing, and managing the dial plan.
CHAPTER 2: DIAL PLAN Dial Plan Concepts and Overview The dial plan configuration file is an ASCII text file that implements the dial plan and specifies pretranslation (digit manipulation). The system is shipped with several default dial plan configuration files, typically, a 3-digit and a 4-digit file for each supported country.
Dial Plan Concepts and Overview Call Process Flow 29 The dial plan configuration file is a key component of inbound and outbound call processing. The dial plan tables in the configuration file process incoming calls in this order: 1 Incoming Dial Plan Table 2 Pretranslator Table The dial plan tables process outgoing calls in this order: 1 Internal Dial Plan Table 2 Least Cost Routing Table After pretranslation (if performed), the final translation process routes the call to the destination.
CHAPTER 2: DIAL PLAN entries. For more information, see TimedRoute Create, TimedRouteEntry Create, and TimedRouteOperation Create later in this chapter. NBX System Database The NBX system database contains a default dial plan that is initially loaded at the factory and is reloaded if you purge the database. The default dial plan for the SuperStack 3 NBX system is a 4-digit plan; for the NBX 100, it is a 3-digit plan.
Dial Plan Concepts and Overview 31 The system is shipped with several default dial plan configuration files, typically, a 3-digit and a 4-digit file for each country that is supported. In addition, the file samples.txt contains several examples that illustrate how you can configure the dial plan configuration file to control how the system manages incoming and outgoing calls. Normally, you completely configure a dial plan before you start to use the system to control the telephones.
CHAPTER 2: DIAL PLAN You can route incoming calls to the Auto Attendant port, and you can instruct the Auto Attendant to route these calls to any internal or external number. CAUTION: If you configure the Auto Attendant so that it can access any external number, you risk the possibility of toll fraud. You can reduce the possibility of toll fraud by explicitly putting specific external numbers into the outgoing dial plan table.
Dial Plan Concepts and Overview 33 The NBX system applies any Class of Service restrictions that are associated with the user's telephone to determine whether to make a call. The system also uses any pretranslator that a device uses and performs any required digit manipulation operations before it actually transmits the digits on the Analog Line Card or Digital Line Card port.
CHAPTER 2: DIAL PLAN Dial Plan Tables Dial plan tables contain information that controls how the system routes calls. Each dial plan configuration file consists of at least three dial plan tables. This section discusses these topics: ■ Dial Plan Command Format ■ Internal Dial Plan Table — Must be table ID 1 ■ Incoming Dial Plan Table — Must be table ID 2 ■ Least Cost Routing Dial Plan Table — Must be table ID 3 ■ Adding New Dial Plan Tables CAUTION: Tables 1, 2, and 3 must exist.
Dial Plan Tables 35 Figure 2 Dial Plan Command Format Call Classification — Used with Class of Service Leading Digits to Collect Table Entry ID Number Table Name Table ID Number Maximum and Minimum Characters to Collect Number of the route (dial tone facility) from Routing Tables Priority (Not Used) Command Table Create 1 Internal / Id Entry / TableEntry Create 1 1 TableEntry Create 1 2 TableEntry Create 1 3 Table Create 2 Incoming / Id Entry / TableEntry Create 2 1 TableEntry Create 2 2 Digits 0 1
CHAPTER 2: DIAL PLAN Table 6 Dial Plan Command Fields (continued) Field Description Table Entry ID Number Table entry number (a unique number for each entry in the table). These numbers are usually in ascending order in the table, but you can change the order. For example, you might want to place a new item near other items of the same type (that begin with the same digit) in order to help you when you troubleshoot the configuration file. Digits One or more digits that begin the dial sequence.
Dial Plan Tables 37 would collect all 4 digits of the extension. If the caller dials fewer than the Min number of digits, the system times out in 20 seconds. Example: If Digits = 2, Min = 4, and Max = 4, the system knows that if the first digit is 2, it must collect no less than 4 and no more than 4 digits before making the call routing decision.
CHAPTER 2: DIAL PLAN Example: You can assign the company’s Vice President of Finance to a group that you name the All Privileges Group. You can set the permissions for that group so that group members have permission to make LongDistance calls during all system modes. Internal Dial Plan Table The Internal dial plan table (table ID 1) defines how to handle calls placed from internal devices, such as NBX Business or Basic Telephones, to a destination.
Dial Plan Tables 39 Command Format” on page 34. For a description of the each element of a dial plan command, see Table 6 on page 35. By default, Line Card ports, Digital Line Card ports, and H.323 gateways use the Incoming dial plan table as their normal dial plan table. An Incoming dial plan table typically has a more restricted list of dialable digits than the Internal dial plan table. You usually cannot dial extensions associated with internal paging or Analog or Digital Line Card ports.
CHAPTER 2: DIAL PLAN Adding New Dial Plan Tables If you are sharing the system with another company or group and want to control calls differently at the two sites, you can add a fourth table. Example: You assign one extension range to Company A and a different range to Company B. The fourth table controls the extension range for Company B, so that outbound calls from Company B’s extensions use only their external telephone lines.
Dial Plan Pretranslators 41 Example: Say that the DDI/DID telephone numbers range from 508-555-4200 through 508-555-4299. The telephone company sends you the last 4 digits of the total telephone number. Internally, you want to use extensions 2000 through 2099. You can define a pretranslator to: ■ Remove (stripLead) the first two digits of the incoming 4-digit sequence. ■ Add (prepend) the digits 20 in front of the remaining 2 digits.
CHAPTER 2: DIAL PLAN Each device can specify only one DDI/DID pretranslator and one CLIP pretranslator. To create or modify a pretranslator, you either edit a dial plan configuration file and import it, or use the NBX NetSet utility and modify an existing dial plan configuration file. The system performs operations in ascending order of operation ID. Operations are both sequential and cumulative. You can also use pretranslators with virtual tie lines to link multiple NBX systems.
Dial Plan Pretranslators 43 When you place a call to an external telephone number, the system can use these pretranslator steps to create the full 10-digit number: 1 Remove (stripLead) the first two digits (20) from the internal extension number of the telephone making the call. 2 Add (prepend) the digit sequence 50855542 to the two remaining digits, creating the full DDI/DID telephone number. 3 Pass the full number to the telephone company.
CHAPTER 2: DIAL PLAN Managing the Dial Plan Configuration File Accessing the Dial Plan Creating Dial Plan Configuration Files This section describes the dial plan configuration file and how to manage it.
Managing the Dial Plan Configuration File 45 When you subsequently import this dial plan, these commands purge any traces of the old dial plan and prevent any conflicts that can result from importing one dial plan on top of an existing one. You create new entries in the dial plan configuration file by typing in new commands (see “Dial Plan Configuration File Commands” on page 100) or by cutting, pasting, and editing existing lines in the file.
CHAPTER 2: DIAL PLAN To import a default dial plan configuration file: 1 In the NBX NetSet – Main Menu window, click Dial Plan. The Dial Plan window appears, displaying the Operations tab. 2 Click the Default File radio button. From the Default File pull-down list, select the default file that you want to use. 3 Click Import. 4 Reboot the system. CAUTION: When you import a dial plan configuration file, the NBX system immediately implements the dial plan.
Managing the Dial Plan Configuration File 47 International Dial Plan Issues Several international dial plan issues warrant attention. See these topics: Customizing an International Dial Plan. If there is no customized dial plan for your country, you may need to modify the default dial plan. See “Modifying a Dial Plan Configuration File” on page 51. If you edit the default dial plan, you can test the changes by making a simulated call. See “Testing a Dial Plan” on page 49.
CHAPTER 2: DIAL PLAN made syntax or content errors. Carefully check any changes that you make to the configuration file before you import them. Exporting (Saving) a Dial Plan Configuration File When you export (save) the current configuration, the system creates a new dial plan configuration file from the current database. You save the new text file using a name that you choose. This example refers to Internet Explorer. If you use another browser, you may need to use slightly different procedures.
Managing the Dial Plan Configuration File 49 The sample default files include examples of such things as timed routes and pretranslators. Verify that you rename the new configuration file with a unique file name so that you do not overwrite the sample default file. 6 Click Save. Testing a Dial Plan This section describes how to test the currently loaded dial plan by placing a simulated call. Even if the NBX system is completely installed and operational, a test places a simulated, not an actual call.
CHAPTER 2: DIAL PLAN To create and run a test using the currently loaded dial plan: 1 In the NBX NetSet – Main Menu window, click Dial Plan. The Dial Plan window appears, displaying the Operations tab. 2 Click Test. The Test Dial Plan dialog box appears. 3 To set up the simulated call, from the Device to dial from list box, select the number from which you want to dial. 4 In Number to dial, enter the number that you want the system to dial.
Managing the Dial Plan Configuration File 51 When the NBX system detects an error in any line of an imported dial plan configuration file, it ignores that line and continues to process all remaining lines in the file. This precaution minimizes the impact of errors on the dial plan. To generate a dial plan report: 1 In the NBX NetSet – Main Menu window, click Dial Plan. The Dial Plan window appears, displaying the Operations tab. 2 Click Report. The dial plan report appears.
CHAPTER 2: DIAL PLAN 3 Edit the dial plan configuration file. A single line of space is required between each dial plan entry. You can type a complete dial plan entry anywhere in the file. 4 Click OK. The Import Confirmation dialog box prompts you to confirm the changes. 5 Click Yes. The system imports the modified dial plan. The Dial Plan Consistency dialog box appears, displaying the results of the error and consistency checks. 6 Make a note of any errors, and correct them by editing the file.
Managing Extensions 53 virtual devices such as the pcXset™ PC soft telephone Client and the ConneXtions H.323 Gateway. The extension length (either 3 or 4), which applies to all extensions on a system, indicates that all extensions contain that number of digits. You cannot mix 3-digit and 4-digit extensions within the same NBX system.
CHAPTER 2: DIAL PLAN Table 9 provides a more detailed explanation of extension types, including default extension ranges and values for 3-digit and 4-digit dial plans. Table 9 Dial Plan Extension Settings Field Purpose (See Notes 1 and 2) Telephone Extensions Range The range of extensions for telephones. ■ SuperStack 3 NBX: 1000–3999 ■ NBX 100: 100–449 TAPI route point extensions are included in the telephone extensions range.
Managing Extensions 55 Table 9 Dial Plan Extension Settings (continued) Field Purpose (See Notes 1 and 2) External Extensions Range The range of extensions that are connected to external devices, such as Analog Line Card ports, Digital Line Card ports (BRI-S/T, T1, E1, ISDN PRI), Call Park, and Paging extensions. Default: Call Park Extensions Range Start External Discovery At ■ SuperStack 3 NBX: 6000–7999 ■ NBX 100: 600–799 The range of extensions for Call Park.
CHAPTER 2: DIAL PLAN Changing Extension Length and Ranges You can view and change extension settings, such as extension length and extension ranges. If you are changing from a 3-digit to a 4-digit plan, import the 4-digit dial plan configuration file before you configure or autodiscover any devices. To view and change extension settings: 1 On the Operations tab, click Settings. The Settings dialog box appears. 2 Make the desired changes to the extension settings. Table 9 describes each field.
Managing Extensions 57 recommends that you take advantage of the Auto Discovery process. For instructions on using the Auto Discovery process or manually adding and configuring a new telephone, see the section on “Adding a New Telephone” on page 125. You can define a user in the system database without assigning a telephone to that user. By defining a user with no device, but with a telephone extension only, you create a phantom mailbox.
CHAPTER 2: DIAL PLAN Table 10 Modify Extension Operations Operation Purpose Change Extension Modifies the first selected extension. Change Extension applies to only one extension at a time. If you select multiple extensions, the NBX system changes only the first extension that you selected. Prepend Prepends the digits in front of all selected extensions. Append Appends the digits to the end of all selected extensions.
Managing Extension Lists 59 Table 11 Extension Lists Extension List ID Description *0001 Contains extension numbers assigned to Line Card ports, for example, TLIM ports. Routes 1 and 2 use this list. *0002 Contains extension numbers assigned to Digital Line Card ports. Routes 1 and 2 use this list. *0003 Contains extension numbers assigned to voice mail. ■ SuperStack 3 NBX: 6400–6499 (See Note 1) ■ NBX 100: 651-662 (See Note 2) Route 3 uses this list.
CHAPTER 2: DIAL PLAN From the Extensions List tab of the Dial Plan window, you can perform these tasks: ■ Adding an Extension List ■ Modifying an Extension List ■ Removing an Extension List The system restricts access to any specific Analog Line Card port or Digital Line Card port. To directly dial the extension number that is associated with one of these devices, you must have diagnostic privileges. In addition, you cannot dial a prefix to obtain a Digital Line Card port.
Managing Extension Lists 61 a Select the extension from the Extensions in List scroll list. b Enter a priority number in the text box below the list (from a high of 1 through a low of 99). c Click the Change Priority in List button. The new priority appears as the number to the left of the item within square brackets. The default value is 50. When the system accesses an extension list, it first attempts to use the highest priority extension. 9 Click OK to enable your changes and leave the dialog box.
CHAPTER 2: DIAL PLAN 5 To add an extension to the Extensions in List scroll list, select it in the Extensions not in List scroll list and click the << button. Use Shift+click to select a block of extensions, or Ctrl+click to select several extensions at different locations in the list. 6 To remove an extension from the extension list, select it the Extensions in List scroll list and click the >> button. The extension moves to the Extensions not in List scroll list.
Managing Dial Plan Tables Determining Which Devices Use Dial Plan Tables 63 You can view or change the devices associated with a particular dial plan: 1 In the NBX NetSet – Main Menu window, click Dial Plan. The Dial Plan window appears, displaying the Operations tab. 2 Click the Tables tab. 3 From the list, select a dial plan table for which you want to list associated devices. To list devices not assigned to any table, select (none).
CHAPTER 2: DIAL PLAN Removing a Dial Plan Table Note that you must not remove any of the predefined tables (Internal, Incoming, or Least Cost). CAUTION: You cannot remove a dial plan table if a device is using it. To remove the table, you must first remove all devices from the Devices Using Table list. To remove a dial plan table: 1 In the NBX NetSet – Main Menu window, click Dial Plan. The Dial Plan window appears, displaying the Operations tab. 2 Click the Tables tab.
Managing Dial Plan Pretranslators 65 5 To move a device to the Devices Using Pretranslator list, select it in the Devices Not Using Pretranslator list and click <<. To move a device to the Devices Not Using Pretranslator list, select it in the Devices Using Pretranslator list and click >>. Then 6 Click Close. Table 13 Pretranslator Fields Field Purpose Pretranslator ID The identification number of the pretranslator as specified in the dial plan.
CHAPTER 2: DIAL PLAN 4 Click Remove. CAUTION: You cannot remove a pretranslator if any device is currently using it. If you want to remove the pretranslator, you must first remove all devices from the Devices Using Pretranslator list. Configuring the Dial Plan for the 4ESS Protocol (T1) The 4ESS protocol, used on T1 Digital Line Cards that are configured for PRI operation, requires specific configuration entries in the NBX system dial plan.
Overview of Voice Profile for Internet Mail 67 Example: If you use route 1 in the dial plan for Long Distance, and users must dial 91 to make a long-distance call, the dial plan entries shown in Figure 5 remove the first two digits (91) and submit the remaining 10 digits to the long-distance carrier.
CHAPTER 2: DIAL PLAN by a firewall. Configure the firewall to allow access to port 25 on the NBX system only from valid VPIM systems that need to deliver VPIM messages to the phone system. The NBX SMTP server is started only when the system has a valid license for VPIM. To send a voice mail message to a user on another VPIM-compliant system, an NBX user first composes the voice mail message, using the commands in the user’s voice mailbox.
Configuring the Dial Plan for VPIM 69 Figure 7 contains sample lines which, when added to an existing dial plan, implement VPIM connections to two other NBX systems, one in Atlanta and one in Dallas. Table 14 explains each entry.
CHAPTER 2: DIAL PLAN Table 14 Explanation of Entries in Figure 7 (continued) Field Purpose V82 (Digits column) The letter V (required, and must be a capital letter) indicates that this is a VPIM connection, and the 82 indicates that the user must dial 82 to access the VPIM connection and then dial the extension the user wants to reach. You can select any number of digits for a site code. The selected number must not conflict with other dial plan entries.
Configuring VPIM Parameters Using NBX NetSet Configuring VPIM Parameters Using NBX NetSet VPIM Control Parameters 71 Using the NBX NetSet utility, you can configure several VPIM control parameters, check the status of the VPIM queues, and obtain statistics on recent VPIM activity. To set the VPIM control parameters: 1 In the NBX NetSet - Main Menu window, click NBX Messaging. 2 Click the VPIM tab. Table 15 describes the fields.
CHAPTER 2: DIAL PLAN Table 16 Operations Management Dialog Box Fields (continued) Field Purpose Number of outgoing messages The number of messages in the outgoing queue when this dialog box was last accessed or refreshed. Outgoing Messages Time Waiting The number of minutes that the voice mail message has been waiting in the queue. # Attempts The number of times the NBX system has attempted to send the voice mail message. Sender The e-mail address of the user who sent the voice mail message.
Configuring VPIM Parameters Using NBX NetSet Statistics 73 To view the most recent statics for voice mail messages, click the Statistics button. The Statistics window appears. Table 17 lists the fields in this window and explains their purpose.
CHAPTER 2: DIAL PLAN Table 17 Statistics Window Fields (continued) Field Purpose Last system reboot The date and time of the most recent reboot of the NBX system. An NBX system reboot resets all VPIM statistics to 0 (zero). If this field’s date and time are more recent than Last reset command, then the NBX system began to collect the currently displayed statistics at this date and time.
Configuring VPIM Parameters Using NBX NetSet 75 Table 18 VPIM Advanced Settings Dialog Box (continued) Field Purpose SMTP EHLO response Definition: The amount of time that the local system waits for acknowledgement of a EHLO message. Detail: After the greeting, the local system sends either a HELO (or EHLO to get ESMTP) message to identify itself. The other site then responds with an acknowledgement of that message. Minimum: None defined.
CHAPTER 2: DIAL PLAN Table 18 VPIM Advanced Settings Dialog Box (continued) Field Purpose SMTP DATA END response Definition: The time that the local system waits, after sending the entire message, for an acknowledgement from the other site that the message was received. Detail: After the local system sends the entire message, it waits for a response from the other site indicating acceptance of the message.
Overview of Virtual Tie Lines Configuring Domain Name Server Information 77 When the SMTP utility attempts to send e-mail, it must be able to resolve a host name within an e-mail address and determine the proper IP address from that name. Domain Name Servers on the Internet perform this function. You can configure up to three DNS entries with the NBX NetSet utility. The NBX system uses the second and third entries if the first or second cannot be reached.
CHAPTER 2: DIAL PLAN There are two implementation techniques you can use: unique extension ranges or site codes, as described next. VTL Connections Using Unique Extension Ranges If you can restrict the extension ranges on each of the NBX systems so that they do not overlap, you can configure the dial plans to route calls based only on the extension that is being dialed. The caller does not have to dial any digits to specify the site.
Overview of Virtual Tie Lines 79 See “Dial Plan Configuration” on page 82 for further information on how to set up VTLs in the dial plan. VTL Connections Using Site Codes The simpler way to implement VTL connections uses a site code, consisting of one or more digits that a user must dial to specify the site that is being called. This approach requires no restriction on the telephone extension ranges, but does require the caller to dial the site code digits as well as the extension.
CHAPTER 2: DIAL PLAN identical extension number at the local site (Chicago). The choice of site codes is made by the person who configures the dial plans for the sites. See “Dial Plan Configuration” on page 82 for more information on how to set up VTLs in the dial plan. Conference Calls Users can set up conference calls over VTLs in much the same way that they set up conference calls with other users at their local site, or at a site reachable by an external telephone line.
How to Configure a Virtual Tie Line 81 5 When the Dallas user answers, press Conference again to connect all four users. Conference Calls Involving Site Codes and Off-Site Telephones In Figure 9, you work in the Chicago office and want to establish a conference call with someone in Atlanta, someone in Dallas, and someone at an external telephone number, you: 1 Dial the Atlanta site code (62) and then the extension.
CHAPTER 2: DIAL PLAN To install a VTL license: 1 In the NBX NetSet - Main Menu window, click Operations. Click the Licenses tab and the Add License button.

How to Configure a Virtual Tie Line 85 Max = 6) sequence. Entry 101 watches for the 2-digit sequence 63 followed by a 4-digit extension and specifies route 523 whenever a user dials such a 6-digit sequence. The choice of route numbers is made by the person configuring the dial plans for the sites. Two DestinationRoute Create commands create routes 522 and 523. The Description field contains any text you want to use to describe each route.
CHAPTER 2: DIAL PLAN 7 Repeat until all VTLs are moved to Extensions in List. Table 19 Virtual Tie Line Extension Ranges Adding VTL Devices to the Pretranslators (Optional) Platform Extension Range SuperStack 3 4-digit dial plan 6500–6523 SuperStack 3 3-digit dial plan The default dial plan for a SuperStack 3 NBX system is 4-digit. If you convert to a 3-digit dial plan, you must manually change each 4-digit extension to a 3-digit extension.
How to Configure a Virtual Tie Line Verification of the Virtual Tie Line 87 After you have configured the VTLs on each of two NBX systems, you must verify that the VTL connection works properly. To verify that a working VTL connection exists between two systems, you must verify that: ■ Local System Verification — Verify that the configured VTLs appear on each system. ■ Remote Access Verification — Verify that each of the systems can access each other.
CHAPTER 2: DIAL PLAN Remote Access Verification To verify that each system can access the other, on each system: 1 On the Virtual Tie Lines tab, select the VTL and then click the Query Remote button. 2 In the Query Remote System window, type the IP address of the remote system in the IP address text box. Click the Query button. If the verification is successful, the window displays the VTLs configured at the remote site.
How to Configure a Virtual Tie Line 89 Atlanta office and specified the IP address of the Chicago system, it should show two installed but idle VTL connections. If the local NBX system fails to access the remote system, an error message appears similar to the one shown in Figure 14. Figure 14 Query Remote Error Message If you have not yet configured the remote system to support VTLs, this message indicates that you must do so before the Query Remote operation can succeed.
CHAPTER 2: DIAL PLAN Placing Telephone Calls The final step when verifying a virtual tie line connection is to place telephone calls in both directions between each pair of connected sites. Call Rerouting for Virtual Tie Lines To enable the NBX system to better deal with network problems, you can configure the system dial plan so that some virtual tie line (VTL) calls can be rerouted if a VTL connection cannot be made.
Call Rerouting for Virtual Tie Lines 91 Figure 15 Sample Dial Plan Entries for Rerouting VTL Calls Table Create 1 Internal 4 Digit Extensions / Id Entry Digits Min Max Class / -- ------ ------------ --- --- ------------TableEntry Create 1 8 72 6 6 WAN Prio Route ---- ----0 6 / Routes / Route Description / ----- ----------DestinationRoute Create 6 Site B / Route Entry DestinationExtension / ----- ----- -------------------DestinationRouteEntry Create 6 1 *0006 DestinationRouteEntry Create 6 2 *0001 / /
CHAPTER 2: DIAL PLAN Successful VTL Call If there are no network problems: 1 The first line (Entry 1, OperId 1) removes the digits 72. 2 The second line (Entry 1, OperId 2) prepends the IP address of the NBX system at site B in front of the dialed extension number. Unsuccessful VTL Call If a network problem or a lack of VTL ports prevents the VTL call from reaching its destination: 1 The third line (Entry 2, OperId 1) removes the digits 72.
Managing Existing Virtual Tie Lines Viewing and Resetting Virtual Tie Line Statistics 93 You can view the statistics for a VTL at any time. To view statistics for a VTL: 1 In the NBX NetSet - Main Menu window, click Device Configuration. 2 Click the Virtual Tie Lines tab. 3 From the list, select the VTL. 4 Click the Statistics button. The Statistics dialog box appears. The fields are described in Table 20. 5 To reset all VTL statistics, click Reset.
CHAPTER 2: DIAL PLAN Table 20 Virtual Tie Line Statistics Fields Enabling Audio Compression Field Description Rerouted VTL calls The number of calls that did not reach their destination when attempted over VTL channels, and were rerouted using another device. Last reset command The date and time of the most recent Reset for this VTL. Last system reboot The date and time of the most recent reboot of the NBX system.
Using a VTL Password 95 To enable silence suppression on VTLs: 1 In the NBX NetSet - Main Menu window, click System Configuration. 2 On the System Settings tab click Audio Settings. 3 Click the System-wide Silence Suppression on VTL Calls check box, and then click OK. Using a VTL Password To allow users on one NBX system to place VTL calls to another NBX system and then place long-distance (toll) calls from that location (a practice called ‘hop off’), you can configure a VTL password.
CHAPTER 2: DIAL PLAN Configuring VTL Passwords in the Dial Plan For each remote NBX system that controls hop-off by means of a VTL password, you must configure that password into the VTL commands in the local dial plan. If you use site codes to access other NBX systems through VTL connections, you can configure one set of VTL connections that permit hop-off and are accessed one set of site codes.

CHAPTER 2: DIAL PLAN The next two TableEntry Create commands are set up in a similar manner to handle VTL connections with passwords. If a user dials 72 followed by a 4-digit extension, the VTL call uses route 524. If a user dials 73 followed by a 4-digit extension, the VTL call uses route 525.
Using a VTL Password 99 To place a hop-off call to 555-1212 in area code 903 through the Atlanta system, a user on a remote system would dial 72919035551212. The 72 code sets up a VTL connection to Atlanta that incudes the Atlanta system’s VTL password, and the remaining digits are used to dial the number (9 accesses an outside line to obtain dial tone from the local carrier, 1 accesses the long-distance carrier, and the remaining digits specify the long-distance number).

If the specified digit manipulation operation already exists, this command overwrites it with the new information.
Dial Plan Configuration File Commands 111 Arguments nDialPlanTableId — An integer in the range 1 through 32768. The default dial plan tables use ID numbers 1 through 3: 1 — Internal dial plan table 2 — Incoming dial plan table 3 — Least Cost Routing table szDescription — The description or name of the dial plan table. the NBX NetSet utility uses this name to refer to the table. Example: This example command creates dial plan table 1 and names it “Internal 4 Digit Extensions.
CHAPTER 2: DIAL PLAN nMinDigits — An integer specifying the minimum number of digits to collect. nMaxDigits — An integer specifying the maximum number of digits to collect. szCallClass — The call class for this dial plan entry. The call class corresponds to permissions granted to users in their Class of Service. Values are Internal, Local, LongDistance, International, WAN, TollFree, Emergency, COCode, Wireless, Other, Toll, AlternateLong, Operator, TrunkToTrunk, Diagnostics, and NotAllowed.
Dial Plan Configuration File Commands 113 nDefaultDestinationRouteId — An integer in the range 1 through 32768 identifying the destination route the system must use if none of the entries in this timed route match the current time of day. szDescription — A description or name of the timed route. Example: This example command creates timed route 7 which uses destination route 1, defined in the “Routes” section of the system configuration file. The description of route 7 is “Business Hours Long Distance.
CHAPTER 2: DIAL PLAN Example: If you define business hours from 8:00 to 17:00 on Mondays, Wednesdays and Fridays, and from 9:00 to 18:00 Tuesdays and Thursdays, then a timed route entry both szStartTime and szEndTime set to “open” applies differently on Monday, Wednesday, and Friday than on Tuesday and Thursday. You set the beginning and ending times for open, lunch, and other using the NBX NetSet utility. Click System Configuration, then the Business Identity tab, and the Business Hours button.
Dial Plan Configuration File Commands 115 The first entry is timed route 7, timed route entry 1. The two occurrences of the word “Open” instruct the system to use the start time and end time defined by the “open for business” hours, and the letters “SMTWTFS” indicate that this entry applies to all seven days of the week (Sunday through Saturday). The number 6 designates destination route 6, defined in the system routes table.
CHAPTER 2: DIAL PLAN Arguments nRouteId — An integer in the range 1 through 32768. nEntryId — An integer in the range 1 through 32768 specifying the timed route entry to which this operation applies. nOperId — An integer in the range 1 through 32768. The system processes the list of operations in ascending nOperId order (nOperId 1 first). szOperation — The name of the digit manipulation operation to perform: stripLead, stripTrail, replace, prepend, append.
Sample Solutions Using Dial Plan Configuration File Commands 117 PreTranslatorOperation Create 1 1 1 stripLead 1 Explanation: For pretranslator table 1, PreTranslatorEntry 1, create the first PreTranslatorOperation. This performs a stripLead operation, removing a single leading digit from the incoming number. Customer Requirement 2.
CHAPTER 2: DIAL PLAN Customer Requirement 3. Assume that the telephone company assigns a group of 4-digit DID/DDI numbers from 6000 through 6199; however, you want to use internal telephone extensions from 3000 through 3199. Also, you want the number 6111 to connect the caller to an Auto Attendant line for the customer service group.
Sample Solutions Using Dial Plan Configuration File Commands 119 TableEntry Create 2 4 3 4 4 Internal 0 0 Explanation: In table ID 2 (Incoming dial plan table) entry 4 instructs the system to look for 3 as the first in a sequence of 4 digits (both Min and Max are 4). If the system finds such a sequence, it assigns Internal as the call class. The system does not use the number in the priority column, so it remains 0 (zero).
CHAPTER 2: DIAL PLAN TableEntry Create 1 48 91508 12 12 LongDistance 0 1 Explanation: In table ID 1 (the Internal table), creates entry 48, which directs the system to look for the digits 91508 at the beginning of any 12-digit sequence (Min and Max are both 12). If the system detects such a sequence, it assigns LongDistance as the class of service.
Sample Solutions Using Dial Plan Configuration File Commands 121 In combination, the five lines in the internal table work with these two lines in the Routes section of the dial plan. DestinationRoute Create 1 Boston Low-cost Carrier DestinationRoute Create 2 T1 Line to DEF Telephone Company Explanation: Creates two routes, numbered 1 and 2, with the names “Boston Low-cost Carrier” and “T1 Line to DEF Telephone Company.

A dialog box prompts you to confirm removal. 4 Click Yes.
CHAPTER 3: DEVICE CONFIGURATION Adding a Remote Telephone Remote NAPT Device Configuration NBX system software (release R4.2 and higher) supports Network Address Port Translation (NAPT, also called NAT overloading). NAPT allows you to put an NBX Telephone behind a device that applies network address translation at a remote location, such as a home office, and connect to the NBX call processor through an Internet connection.
Creating and Managing Bridged Extensions 135 ■ Subnet Mask — The address mask in use on the LAN side of the NAPT device. ■ Default Gateway — The IP address of the NAPT device on the LAN. For details on how to use the LUI utility, see “Using the Telephone Local User Interface (LUI) Utility” on page 352. 4 Configure the NAPT device: ■ Creating and Managing Bridged Extensions Use the device’s virtual server feature to map UDP ports 2093-2096 to the NBX telephone.
CHAPTER 3: DEVICE CONFIGURATION Provided that you do not exceed the limits shown in Table 25, you can configure the maximum number of bridged extensions using any combination of primary telephones and bridged extensions. For example, on a SuperStack 3 NBX system, you can configure 400 primary telephones with three bridged extensions each or 300 primary telephones with 4 bridged extensions each to reach the limit of 1200.
Creating and Managing Bridged Extensions 137 When you define bridged extension appearances on a primary telephone: Example Bridged Extensions Configurations ■ Incoming calls appear on the bridged extension buttons first, followed by the buttons (if any) associated with the primary telephone’s extension. For example, by default, buttons 1, 2, and 3 are extension appearances of the primary telephone.
CHAPTER 3: DEVICE CONFIGURATION which extension 1077 is to appear. On the 1088 telephone, buttons 10, 11, and 12 are configured as bridged extension buttons. On the 1099 telephone, buttons 3, 4, 5, 6, and 7 are configured as bridged extension appearances for extension 1077.
Creating and Managing Bridged Extensions 139 3 Click Button Mappings. The Telephone Button Mappings dialog box (Figure 17) appears. Figure 17 Telephone Button Mappings Dialog Box 4 For each button that you want to include in the group of bridged extension buttons: a Select Bridged Extension from the drop-down list in the Type column. b Type the extension number of the primary telephone in the Number column.
CHAPTER 3: DEVICE CONFIGURATION 3 Click Button Mappings. The Telephone Button Mappings dialog box appears. 4 For each button that you want to include in the group of bridged extension buttons: a Select Bridged Extension from the drop-down list in the Type column. b Type the extension number of the primary telephone in the Number column. See Figure 18.
Creating and Managing Bridged Extensions 141 ■ The primary telephone is an NBX Business telephone (extension 1027) used by a manager (Alicia). This telephone has buttons 2, 3, and 4 defined as bridged extension buttons. Button 1 is the manager’s private line. ■ One secondary telephone, an NBX Business Telephone (extension 1051), is used by the manager’s assistant (Bradley).
CHAPTER 3: DEVICE CONFIGURATION A fourth call arrives at Alicia’s extension and rings on button 1. Neither Bradley nor Connie can answer this call because that button on Alicia’s telephone is not a bridged extension appearance. If a fifth call arrives at Alicia’s extension before the fourth call stops ringing, it is sent directly to Alicia’s voice mailbox, because all buttons are being used. Example 4: A call arrives at Alicia’s telephone and the building has been evacuated because of a fire.
Creating and Managing Telephone Groups Creating and Managing Telephone Groups 143 Telephone groups let you create common Button Mappings. Button mappings let you assign specific actions to the buttons on an NBX Business Telephone. When you associate a Group with a specific telephone, the telephone inherits all the mappings of the Group. For example, you can create a Group called Sales that includes Access buttons mapped to a set of CO lines.
CHAPTER 3: DEVICE CONFIGURATION To change the name of a telephone group: 1 Select NBX NetSet > Device Configuration > Telephone Groups. 2 Select the group whose name you want to change. 3 Click Modify. The Modify Telephone Group dialog box appears. 4 Change the name of the telephone group in the Group Name field. 5 To set call recording and monitoring as the default condition for all telephones in this telephone group, enable the Call Record & Monitor check box.
Recording and Monitoring Telephone Calls 145 To enable call recording and monitoring on the NBX system, you must purchase a system-wide license. After you install the license, you can enable call recording and monitoring for these devices: ■ ■ ■ Recording Calls Between Telephones with Different Recording Settings Analog telephones connected to ports on an Analog Terminal Card or to a Single-Port Analog Terminal Adapter.
CHAPTER 3: DEVICE CONFIGURATION ■ An analog telephone connected to an ATC port on the local NBX system ■ An NBX Basic Telephone on a different NBX system, connected to the local NBX system by a virtual tie line (VTL) Only the NBX Basic Telephone has recording enabled. For the duration of the conference call, the NBX system enables recording for the analog telephone and the NBX Business Telephone.
Creating and Managing Button Mappings Creating and Managing Button Mappings 147 Button Mappings allow you to place features, such as speed dial numbers and shortcuts, on telephone buttons for individual telephones or for telephone groups. In addition, you can use Button Mappings to map CO telephone lines to buttons and set up your system in one of these modes: ■ Key Mode system — In Key Mode, all outside lines map to individual buttons on users’ telephones.
CHAPTER 3: DEVICE CONFIGURATION NBX Basic Telephones include three Access buttons. NBX Basic Telephones operate in PBX mode only, that is, you cannot map CO lines directly to telephone buttons. Mappings for Users and Groups When you create a new user and assign the user to a group, the button mappings for that group become active for the user’s telephone. You can override group mappings and create mappings for individual telephones.
Creating and Managing Button Mappings Creating a Delayed Ringing Pattern 149 You can define a ringing progression for a line that is mapped to multiple telephones. For example, you can configure a call to ring immediately at telephone 1, begin ringing at telephone 2 after 4 rings, and then begin ringing at telephone 3 after 8 rings. Any of the telephones can pick up the call at any time, even if it has not yet started audibly ringing at a particular telephone. (The light flashes during all rings.
CHAPTER 3: DEVICE CONFIGURATION Creating Groups and Button Mappings Telephone Button Mappings are part of a device. You assign a set of mappings to an individual by associating a particular device or group to that user. A user can see the Button Mappings in effect for an assigned telephone by logging on to the NBX NetSet utility with a personal password. The user can also use the NBX NetSet utility to create and print labels for the Access Buttons on the telephone.
Creating and Managing Button Mappings 151 ■ The large Access buttons (the buttons without lights on NBX 2102 and 1102 Telephones) cannot serve as line appearances. ■ NBX Basic Telephones do not support line appearance. ■ Telephone Button Mappings are part of a device. You assign a set of mappings to an individual by associating a particular device or group to the user. ■ Users can see the Button Mappings in effect for their telephones by accessing the NBX NetSet interface with a personal password.

You can also modify and maintain user profiles and parameters.
CHAPTER 4: USER CONFIGURATION Call Pickup Group Numbers In some organizations, it can be useful if any user who hears a telephone ringing can pick up the call on her or his own telephone. Using the Call Pickup feature, you can create one or more Call Pickup groups to allow this convenient sharing. Pickup group numbering differs for SuperStack 3 NBX systems and NBX 100 systems.
TAPI Route Points TAPI Route Points 265 A TAPI Route Point is a virtual device within the NBX system where calls are held pending action by an external TAPI application. Route points are typically used by call center applications to redirect calls. A redirected call is one that is sent from its original destination (the route point) without being answered, to a new location specified in the external application.
CHAPTER 4: USER CONFIGURATION Table 50 TAPI Route Points and NBX System Features (continued) Call Redirected to Description External number Subject to the route point extension’s Class of Service setting. The call connects as soon as the external line resource (line card port, a PRI line, or a T1 channel) is acquired. The caller hears the call progress tones directly from the CO. At this point, the NBX system logs a successful connection.
TAPI Route Points TAPI Route Point Capacities 267 When the maximum number of calls on a route point is reached (see Table 51), subsequent calls routed into the route point from an internal extension or through a Virtual Tie Line ring for 10 seconds and are then disconnected. If the call arrives through a line card port, the call continues ringing.

The maximum queue sizes are: SuperStack NBX: 400 calls NBX 100: 50 calls NOTE: To facilitate sorting, numbers in this column are rounded up to the next highest integer. Example: 178 calls in queue on a SuperStack 3 NBX system % Used = 178/400 = 44.
Hunt Groups Hunt Groups 271 A hunt group is a set of users that can be accessed by dialing a single extension. A call routed to the hunt group extension can reach any member of the group who is currently logged into the group. A static hunt group is one in which all members are permanently logged in (locked).

7 OPERATIONS This chapter describes how to manage system-level operations for your NBX system. You can perform these operations from NBX NetSet: ■ Software Upgrade ■ Reboot/Shutdown ■ Manage Data ■ Event Log ■ Licenses ■ Regional Software ■ Third-Party Drivers See the Help for the procedures for each function. Software Upgrade As part of the upgrade and reboot process, you can choose to use your existing configuration data with the new version of the software or use a new (empty) database.
CHAPTER 7: OPERATIONS ■ When the software upgrade is complete, a new window, containing a confirmation message, appears in NBX NetSet. ■ At certain times during an upgrade, the system reboots itself. Do not interrupt the reboot; wait until the upgrade is complete. ■ Before you upgrade your system software, 3Com recommends that you back up your system data. (See “Backup” on page 336.
Software Upgrade 333 If you decide not to install the R4.2 license key, you can click the Reboot button and select a different release. Upgrading From R4.1.15 and Later Versions If you are running R4.1.15 or a later release of R4.1, you can enter the R4.2 license key and then upgrade. When you enter the license key, the NBX system software accepts the license key as valid for an unknown feature. When you upgrade and reboot to R4.2, the license for R4.2 takes effect. Upgrading From Release 4.
CHAPTER 7: OPERATIONS ■ You can click the Reboot button to go to a reboot screen and reboot to a previous NBX software release. ■ You can click the License button to go to a license screen and enter a license key for R4.2. The installation of a valid upgrade license removes all restrictions without the need for an NBX system reboot operation. Considerations Some situations require specific actions because of the system software licensing mechanism.
Reboot/Shutdown Customer Service Reboot/Shutdown 335 If you reboot to R4.2 without installing a valid license, and you run your system with the restrictions in place (see “Restricted Operation” on page 333), 3Com Customer Service cannot access the information required to help you with problems. To obtain assistance from 3Com Customer Service, you must either reboot to a previous version of the NBX system software or install a license for R4.2. You must reboot the system after you upgrade software.
CHAPTER 7: OPERATIONS Backup Back up your system data: ■ After you change system settings ■ Immediately before you change any system hardware or software When you back up your system data, you can choose to include or not include the voice mail messages for all system users. License backup operations are part of a separate backup operation. To backup your licenses, select Operations > Licenses. During a backup operation, NBX NetSet displays a series of progress screens.
Manage Data ■ Exit your browser ■ Shut off your computer 337 If another administrator tries to back up the system database before the current backup task has been completed, a message appears that warns them that a backup is currently in progress. The message includes: ■ The IP address of the computer from which the backup was started Use the IP address to find the person who started the backup and coordinate their backup and yours.
CHAPTER 7: OPERATIONS The NBX system keeps a copy of the most recent backup file on your NBX system. Each time you perform a backup operation on the NBX database, the NBX system overwrites this file. If you choose to not save the backup file during the backup procedure or if you forget to save it, you can save it later. However, if you perform another backup, the prior backup file is no longer available. To save the most recent backup file to a location you choose: 1 Click the Save As button.
Event Log 339 3 Click Restore. 4 In the window that appears, the NBX system provides cautionary information about the effect of a restoration on system operation and prompts you to confirm that you want to restore the database. Click Yes to restore the database, or No to cancel the operation. If you choose to restore the database, the NBX system automatically reboots after the database file is loaded.
CHAPTER 7: OPERATIONS To view event logs, select Operations > Event Log. See the Help for the procedure on viewing event logs. Licenses You can install licenses for these components: ■ NBX system software ■ IP telephones (Standard IP or IP-on-the-fly) ■ H.
Licenses 341 To configure the system to support new licenses, contact your 3Com Voice Solutions dealer and provide the serial number. The dealer obtains a new license key from 3Com Customer Support that enables the upgrade. See the Help for procedures for adding a license to an NBX system. Remove a License The only license that you can remove from an NBX system is the disk mirroring license, which enables a SuperStack 3 NBX system to use two disks in a mirrored configuration.
CHAPTER 7: OPERATIONS Obtaining Details of License History You can view a detailed history, including the date and time on which each license was added to the NBX system. In the Operations > Licenses dialog box, click Details. Table 74 describes each column in the Details report window. Table 74 Explanation of License Details Window Field Purpose Name The name of the license. Description A description of the license.
Regional Software 343 After you install regional software, you must designate it to be the current system regional software by selecting System Configuration > Regional Settings. Remove You can remove regional software at any time. All versions of the regional software that you select are removed. For example, if you choose to remove the “Mexico - Spanish” regional pack, all versions of the selected regional software are removed from the system. U.S. English cannot be removed.
CHAPTER 7: OPERATIONS Table 75 Diagnostic Details (continued) Third-Party Drivers Values Description Error While Loading An error occurred while loading the regional software. Re-install the software. Nothing Installed The system is aware that this regional software exists, but no version is installed. You can add and configure third-party telephones for use on an NBX system. The third-party vendor supplies the interface hardware and a software package to support the telephones.
8 REPORTS This chapter describes how to access details of NBX system data traffic.

Telephone Troubleshooting Using H3PingIP 359 You can use the H3PingIP menu item to ping another device on the network to test the telephone’s connectivity and to check the packet delay. When using H3PingIP to test for connectivity, you must use the IP address of a device that is connected to the NBX system NCP. You should not use the NCP IP address. The NBX Business Telephone uses the IP Gateway and subnet mask information programmed into it using the AB16 and AB17 buttons.
CHAPTER 10: TROUBLESHOOTING System-level Troubleshooting For each symptom listed in Table 78, perform the suggested actions in the order listed. WARNING: Before you remove any component, shut down the system software and then turn off the power to the chassis by removing the chassis power cord. If the system has two power supplies, remove both power cords.
System-level Troubleshooting 361 Table 78 Troubleshooting Actions (continued) Symptom Possible Cause Suggested Action Invalid IP configuration The system has a default IP configuration which might need to be changed to match your local IP environment. Temporarily change the IP configuration of your computer so that the subnet configuration matches the system configuration. Specify 255.255.255.0 as the subnet and use IP address 192.168.1.191.
CHAPTER 10: TROUBLESHOOTING Table 78 Troubleshooting Actions (continued) Symptom Possible Cause Suggested Action NBX NetSet is very slow in responding. Your network uses a proxy server for Internet access. A common networking practice is to employ a proxy server to shield your network from intrusion by unauthorized users. However, communications with NBX NetSet do not need to pass through the proxy server.

D CONNEXTIONS H.323 GATEWAY This appendix provides information on how to install and configure the 3Com ConneXtions H.323 Gateway. It covers these topics: ■ Overview of ConneXtions ■ Installation Requirements ■ Preparing for Installation ■ Installing ConneXtions ■ Overview of H.323 ■ The H.323 Connection ■ Connection Considerations ■ Special Issues ■ Checking Connections ■ Placing Calls ■ Receiving Calls ■ Handling Conference Calls ■ Related H.
APPENDIX D: CONNEXTIONS H.323 GATEWAY Overview of ConneXtions ConneXtions is a 3Com software product that allows you to use an appropriately configured Windows system as an H.323 gateway for use with NBX systems. H.323 gateways implement an ITU standard that allows telephone-like call connections to occur through an IP network. Although this standard addresses the means for transferring data, voice, and images, the NBX ConneXtions H.
Installation Requirements 389 the H.323 protocol presents special problems for firewalls because it requires additional processing. To minimize packet delay through a firewall, verify that the firewall is configured to give H.323 packets a high processing priority. During installation, you can select a range of TCP or UDP ports to use with H.323 connections to provide more flexibility when using firewalls. A ConneXtions gateway can use a separate network interface card to bypass the firewall delay.
APPENDIX D: CONNEXTIONS H.323 GATEWAY Processor, Memory, and Bandwidth Requirements Each G.711 call needs about 50 MHz on a Pentium II or 20 Mhz on a Pentium III. Each G.723 call needs about 128 MHz on a Pentium II or 75 Mhz on a Pentium III. These speed requirements increase directly with the number of ports. The IP router bandwidth requirements also increase directly with the number of ports. The bandwidth requirements for a Pentium II and a Pentium III are identical.
Installation Requirements 391 Table 85 Pentium II and III Processor Capabilities Pentium II Ports Pentium III Ports (MHz) G.711 G.723 (MHz) G.711 G.723 300 6 2 450 22 6 400 8 3 500 25 6 500 10 4 533 26 7 600 12 4 550 27 7 650 13 5 600 30 8 Dual 500 20 8 650 32 8 667 33 8 700 35 9 733 36 9 750 37 10 800 40 10 1500 74 20 The maximum number of ports can be limited by the number of licenses.
APPENDIX D: CONNEXTIONS H.323 GATEWAY configuration is appropriate if the firewall, which separates Internet and intranet, is either unnecessary or is required by company policy. ConneXtions Software You use the NBX Resource Pack CD to install ConneXtions software. The ConneXtions software performs the protocol conversions between an NBX system and the international H.323 standards. To a system administrator, H.323 ports look like PSTN line ports.
Preparing for Installation Verifying the G.723 Converter 393 Installations that need G.723.1 audio compression require access to a converter in Microsoft NetMeeting 2.1 or 3.01. NetMeeting must be installed on the same PC that holds the ConneXtions software, but the two cannot run simultaneously. G.723.1 does not appear as a selectable option in ConneXtions unless the converter is accessible. To confirm that the convertor is present, search for the msg723.
APPENDIX D: CONNEXTIONS H.323 GATEWAY 2 Access and record the Call Processor MAC address: a In the NBX NetSet - Main Menu window, click Reports. b Click the System Data tab. c Record the MAC address. MAC addresses use colons as separators. Take care to record the Call Processor MAC Address, not the Music-on-Hold MAC address, which also appears in the System Data tab. 3 Determine the number of port licenses: a Return to the NBX NetSet - Main Menu window. b Click Operations. c Click the Licenses tab.
Installing ConneXtions Installing ConneXtions 395 To install the NBX ConneXtions H.323 Gateway: 1 Insert the NBX Resource Pack CD into the PC. Click NBX Applications, and then click NBX ConneXtions, and then click OK. If the program does not start automatically, click the Windows Start menu, and then Run. Type D:autorun, substituting the letter of your CD-ROM drive for D, and click OK. 2 Respond to these initial InstallShield dialog boxes: a In the Welcome dialog, click Next.
APPENDIX D: CONNEXTIONS H.323 GATEWAY 8 Only one Gateway? - Click Yes if the NBX system has only one H.323 gateway system. CAUTION: Multiple gateways must have unique configurations. Multiple gateways need a distinguishing “Gateway Number”. Assign the first installed gateway to number 0; the second to number 1; and so on. 3Com recommends that licenses be allocated equally when using multiple gateways. 9 Enter the Call Processor MAC Address.
Installing ConneXtions 397 15 Do you want to use alternate Gatekeepers? If you select Yes, the chosen gatekeeper maintains a list of alternate gatekeepers to be used if the preferred gatekeeper does not respond.
APPENDIX D: CONNEXTIONS H.323 GATEWAY Overview of H.323 The H.323 standard provides a foundation for audio, video, and data communications across IP-based networks, including the Internet. By complying with H.323, multimedia products and applications from different vendors can interoperate, allowing users to communicate without concern for compatibility. An NBX ConneXtions H.323 Gateway provides connections similar to tie lines between existing NBX systems across an IP network.
Overview of H.323 399 connection alive until one of the parties ends the connection. A call tear-down signal indicates to the network, and to the other party, when a call ends. On standard telephone networks, the telephone company uses this signal to determine when to start and stop charging for long distance calls, but long distance charges do not normally apply to H.323 calls.
APPENDIX D: CONNEXTIONS H.323 GATEWAY (G.711 and G.723), H.323 gateways negotiate the type of compression they use during each call setup. Negotiation ensures that the compression on the transmit side matches the decompression processing on the receiving side. With the frame and packet overhead, each G.723 channel needs about 19.2 Kbps of the available bandwidth. Standard Extensions Remote Internet Device Connections ConneXtions routes incoming H.
The H.323 Connection 401 POTS Adapters You can purchase circuit boards that plug into a personal computer and adapt an analog telephone (POTS) for use with an H.323 connection. H.323 Gatekeepers The gatekeeper is an H.323 entity on the network that provides address translation and controls access to the network for H.323 terminals, Gateways, and MCUs. The gatekeeper also provides services to the terminals, Gateways, and MCUs, such as managing bandwidth and locating Gateways. The H.323 Connection H.
APPENDIX D: CONNEXTIONS H.323 GATEWAY Connection Considerations As soon as an end-to-end connection has been set up, all three networks (local LAN, WAN, and remote LAN) are ready to pass voice packets. The NBX Business and Basic Telephones use their DSP to convert spoken words into digital voice packets. The voice packets are transferred across the Ethernet to the local H.323 gateway.
Connection Considerations 403 Because so many devices share the same physical media on the Internet and on the local network, there is always the possibility of incomplete or degraded connections that arise from network congestion, device configuration, or addressing problems. Bridges, switches, routers, and firewalls can help to manage network congestion, conversions, and security. Configuration problems with of any of these devices can cause connection difficulties.
APPENDIX D: CONNEXTIONS H.323 GATEWAY Bandwidth Bandwidth is the capacity to carry information. By using H.323, the same bandwidth that supports one uncompressed G.711 voice connection can, instead, support several compressed G.723 conversations with little noticeable difference in quality. Networks differ in the age of their equipment and in the quality of their service. Traffic can form a bottleneck if network loads force a wide area service provider to route traffic through old equipment.
Connection Considerations 405 gateway generates a silence indicator or sends frames filled with silence, depending on the silence suppression mode. Connections Sometimes packet loss is caused by a poor physical connection. This type of packet loss is more likely to occur in a LAN than in a WAN. Typical causes are faulty wiring, connectors, and termination. High-bandwidth LANs (100BASE-T) are more likely to have termination problems than 10BASE-T LANs.
APPENDIX D: CONNEXTIONS H.323 GATEWAY Quality of Service Control NBX systems address Quality of Service (QoS) issues using methods that are discussed in this section. Adaptive Jitter Buffering All IP network devices use buffers to retime the packets that they receive from a network. Retiming allows these devices to compensate for the variable delays that occur as the packets pass through an IP network. H.
Connection Considerations 407 NBX systems use the latest developments to address voice packet priority concerns at the Layer 2 Ethernet level and at the Layer 3 IP network level. Layer 2 NBX systems address Layer 2 priority concerns through the 802.1(p and q) standards. These standards have two parts. The first part addresses the way Ethernet frames get onto the local “wire.
APPENDIX D: CONNEXTIONS H.323 GATEWAY Special Issues Firewall Security This section describes issues related to H.323 telephony in general and to ConneXtions gateways in particular. These include: ■ Firewall Security ■ Gateway Load ■ Remote Access ■ PBX Connections ■ Class of Service ■ IP Type of Service and Differentiated Services ■ Alternate Gatekeepers Firewalls determine which packets can cross the boundary between a protected network (intranet) and the public internet.
Special Issues 409 3Com recommends that a high-performance PC be dedicated to the ConneXtions software. The question of whether an operating system is adequately “secure” is a subject of debate. The concern is that Windows has many IP ports of its own. One way to deal with these ports is to set up a firewall that limits the range of externally accessible ports.
APPENDIX D: CONNEXTIONS H.323 GATEWAY The ConneXtions gateway uses these default port assignments: ■ For UDP traffic, ConneXtions uses ports 8000-8099 by default. Calls require four UDP ports each. ■ ConneXtions uses ports 1025-5000 for TCP traffic. You can configure TCP ports during installation. During ConneXtions installation, you can configure the TCP ports that are used for incoming calls. For outgoing calls, no control is possible. Port 1720 must be preserved.
Special Issues 411 You can use Microsoft’s VPN Dial Up Networking (version 1.3) to establish a virtual private network connection between a roaming laptop and the NBX system LAN. One end of the VPN connection is in the laptop while the other end must be located in a VPN server between the router and firewall. The VPN server provides caller authentication and a secure (encrypted) channel across the internet.
APPENDIX D: CONNEXTIONS H.323 GATEWAY Tie-line connections between NBX and PBX systems require technical people from both ends of the connection to collaborate in these major areas, discussed next: ■ H.323 Interoperability ■ IP Addressing ■ Voice Ports ■ Extension Dial Plans ■ Extension Delay H.323 Interoperability H.323 protocol stacks provide the foundation for H.323 compatibility. Each consists of a collection of engineered software products that implements the H.323 standard.
Special Issues 413 Outgoing IP addresses can be entered: ■ As pre-programmed speed dial numbers that forward callers to the Auto Attendant at a remote NBX system. ■ By modifying the dial plan. You can configure the speed dial numbers to include an appended extension if a person in one NBX system needs to make frequent calls to someone in another NBX system. Alternatively, you can configure the dial plan to route these calls seamlessly to the caller.
APPENDIX D: CONNEXTIONS H.323 GATEWAY Extension Delay Call setup times for digital connections, compared to analog connections, are instantaneous so there is no need to include a delay between the IP address and an appended extension. Incoming H.323 calls to an NBX system usually go directly to the Automated Attendant. Although the Auto Attendant can respond with voice instructions, the call does not have to wait until the end of the voice instruction to respond.
Checking Connections Alternate Gatekeepers 415 A zone can contain only one gatekeeper at a time, although multiple distinct devices can provide the gatekeeper function in a zone. Multiple devices that provide the RAS signaling function for the gatekeeper are called alternate gatekeepers. Each alternate gatekeeper appears to each endpoint as a distinct Gatekeeper.
APPENDIX D: CONNEXTIONS H.323 GATEWAY Local Considerations All voice packets that move between an NBX Business or Basic Telephone, Call Processor, ConneXtions gateway, and router on the LAN have a high priority and high quality of service. However, at the router and beyond, network administrators can influence H.323 call quality through the priority that they give to H.323 packets at both the internet router and at the firewall.If H.
Checking Connections ■ ■ ■ 417 (It is normal for a first ping to fail and subsequent pings to succeed.) Subsequent requests timed-out (Indicates some packet loss. Rerun using the “-n 100” option. The “request timed out” number represents the percentage of lost packets. These packets could have been lost in either direction.
APPENDIX D: CONNEXTIONS H.323 GATEWAY In addition to the NetMeeting software, participating computers need an audio card with a headset (or speakers) and a microphone. The audio card must support full-duplex 64 Kbps transfers. Note that it is possible for a NetMeeting connection to be unsuccessful and still have a successful ConneXtions installation. This can occur because ConneXtions restricts the range of TCP and UDP ports used but NetMeeting allocates its ports from a wider pool.
Checking Connections 419 a Select Open when the download is complete. b Click Yes to confirm installation. c Click Yes to acknowledge the legal agreement. d Click OK to accept the default installation directory. e Click OK to acknowledge successful installation. 7 Open NetMeeting: a Click Next on next two screens. b Enter your details as required. c Click Next on next two screens. d Click Put a Shortcut to NetMeeting on My Desktop. e Click Next on next two screens. f Click Test.
APPENDIX D: CONNEXTIONS H.323 GATEWAY ■ Call rings remote end and it answers, but there is no audio. Faulty connection to a microphone, speaker or both. Firewall is blocking audio (UDP) packets. ■ Placing Calls Calls work in one direction, but not in the reverse direction. Place a call to determine which firewall is blocking TCP traffic. Once you determine this, it is the remote firewall that is blocking the traffic. You can place an outgoing H.
Placing Calls 421 Extension Lists You can configure H.323 ports for single-digit access (usually 8) instead of a specific 3-digit line extension. The single-digit access allows the NBX system to select an available line port when you place an external call. Internet IP line ports and CO (central office) line ports must never be assigned to the same extension list because they use very different dial plans.
APPENDIX D: CONNEXTIONS H.323 GATEWAY Speed dial numbers can be system-wide or personal. System speed dial numbers (700-799) apply system-wide and are programmed by the system administrator. Personal speed dial numbers (601 through 699) apply only to an individual telephone; they are programmed by its owner. You can assign any of the first ten speed dial numbers in each type group, system or personal, to any Access button on a telephone. For more information, see Chapter 6 of the NBX Telephone Guide.
Placing Calls One Button Access 423 You can configure an Access button on a NBX system to dial a complete H.323 (or switched) dial sequence. This procedure assumes that all buttons available for one-button access are configured in the first ten system (or personal) speed dial locations. To set up one-button dials: 1 In the NBX NetSet - Main Menu window, click Device Configuration. 2 Click the Telephones tab or the Group Telephones tab. Select a telephone extension or a telephone group.
APPENDIX D: CONNEXTIONS H.323 GATEWAY Receiving Calls Auto Attendant ConneXtions gateways route incoming calls to any available H.323 port. The NBX system then connects this port to the extension specified during port configuration. H.323 ports are configured through the NBX software just like line card ports.
Receiving Calls 425 Attendant Console By convention, NBX systems reserve extension 100 or 1000 for the Attendant Console (receptionist), although the Attendant Console can be assigned any internal extension number. Outside callers cannot reach internal extensions without operator involvement when incoming calls are directed to the Attendant Console. See “Adding an Auto Attendant” in Chapter 6. Other Extensions Incoming H.323 calls can be routed directly to some other extension or to a phantom mailbox.
APPENDIX D: CONNEXTIONS H.323 GATEWAY Handling Conference Calls You can include gateway port connections in local conference calls along with PSTN line connections. However, ConneXtions does not support conferences at the H.323 level, so, if two or more of the conferring parties are at a remote NBX system, each requires a separate port connection. This characteristic determines who can initiate the conference call.
E CALLER ID Caller ID behavior varies depending on the type of device and the conditions under which the call is received.
APPENDIX E: CALLER ID from the top line appears on the bottom line. After an additional five seconds, if the Caller ID information from the top line exceeds the capacity of both display lines, the numeric portion is removed and only the name portion appears in the display. Specific Caller ID Situations Analog Telephones The Caller ID information that appears in the telephone display panel can be different in some specific call situations.
Specific Caller ID Situations Bridged Extension Telephones Calls That Are Forwarded Multiple Times 429 Caller ID information appears in exactly the same way on a bridged extension telephone as it does on a non-bridged extension telephone. See “Caller ID” on page 427 and “Long Caller ID Character Strings” on page 427.
APPENDIX E: CALLER ID External ISDN BRI Calls An external call arrives at an NBX system on an ISDN BRI channel and is routed to A’s telephone. When A transfers the call to B, the Caller ID (if any is provided by the telephone company) appears for five seconds in the top line of B’s telephone display panel. If no caller ID information is available, the Trunk name and channel number from the Digital Line Card appear on the top line of B’s telephone display panel. A’s ID appears on the bottom line.
Specific Caller ID Situations Internal Calls Nortel Phones Parked Calls 431 On a single NBX system, user A calls B who transfers the call to user C. In C’s telephone display panel, the top line contains Caller ID information for A and the bottom line contains Caller ID information for B. If you have Nortel telephones connected to your NBX system using the Nortel interface card, the behavior of Caller ID on these telephones is identical to the behavior on NBX telephones.
