2. Introduction and Overview Congratulations on your purchase of the OmniConnect/ISDN! The OmniConnect series of access device offers an inexpensive, complete ISDN Internet access solution for the small or branch office. The OmniConnect/ISDN is ideal for Small Office Branch Office (SOBO) applications such as network-wide Internet access and making LAN-to-LAN connections to remote nodes.
Both interfaces support two independent Bearer (B) channels that can be connected to two destinations or bundled for one connection to support Bandwidth-On-Demand. In addition to standard data bearer services, the OmniConnect access devices support Data over Voice (DOV) service. In some areas, DOV allows the use of inexpensive voice bearer services while transmitting data, thus saving on long distance and other toll costs. 2.1.5.
2.1.8. DHCP server DHCP automates IP addressing and reduces the number of IP addresses a site might require. The OmniConnect can function as a dynamic host configuration protocol (DHCP) server. When a DHCP server is enabled and configured, it assigns and manages IP addresses from a specified address pool to DHCP clients. The options supported by this server are sufficient for 255 TCP/IP clients. If more IP addresses or options are required, a higher-capacity DHCP server (i.e., Windows NT) could be used. 2.
2.2. Security features The OmniConnect/ISDN access device provides the following security features: • PPP authentication support, including Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP) • Password security for local and remote telnet and configuration access • TCP, UDP and IP filtering based on source and destination IP addresses, source and destination ports TCP and UDP ports, and IP packet types.

numbers attached to a single phone (each ringing the same phone). This helps the user respond to incoming calls differently based on the number dialed. 3.5.2. ISDN switch types The OmniConnect/ISDN supports the switch types described in this section. In North America, telephone companies primarily provide BRI service with AT&T or Northern Telecom switches 3.5.2.1. National ISDN-1 National ISDN-1 (NI-1) BRI switches comply with established National (United States) ISDN standards.
different pieces of terminal equipment used on the BRI line. These numbers are also used for allocation to the analog telephone port. Note: International ISDN BRI lines are not assigned SPIDs. 3.5.3. ISDN provisioning with IOCs ISDN service may be ordered using ISDN Ordering Codes (IOCs) or capability packages. If the local telephone company supports IOCs, the instructions in this section are applicable. For the purposes of ordering ISDN lines, capability package designations and IOC codes are equivalent.
U/EZ-ISDN 1 does not provide support for simultaneous voice and data on the same Directory Number, only alternating voice and data is supported. Therefore, if a DN is being used for a data call, it will be unavailable for an incoming voice call. Incoming calls to the DN being used will ring busy. However, if the other DN is free, incoming calls will be allowed on the that DN. Outgoing voice calls are possible since the OmniConnect controls the outgoing calls for both data and voice.
3.5.4. ISDN provisioning without IOCs This section provides the information required when an ISDN BRI line is ordered without an IOC. The BRI switch provisions are summarized by switch type (AT&T and DMS-100) for each of the options that the switches support. When the ISDN BRI line is being ordered photocopy the appropriate summary for your BRI switch type and attach it to the worksheet or order form. This will ensure correct provisioning of the ISDN switch.

♦ Circuit Switched Voice Channel (CSV CHL) This parameter sets which bearer channel should be used for the voice call. This parameter should be set to ANY to allow either B channel to be used. ♦ Circuit Switched Voice Additional Call Offering (CSV ACO) This parameter allows incoming voice calls when the bearer channel is busy with a data call. This feature provides notification to the ISDN CPE equipment that a call directed to the CPE is present at the switch, even though the bearer channel may be busy.
3.6.1. Generic SPIDs for NI-1 and NI-2 service A generic SPID format for National ISDN-1 (NI-1) and National ISDN-2 (NI-2) service is used by some telephone companies. The format for these generic SPIDs, which are the same for all switches, is as follows: aaannnnnnnsstt • aaa is the 3-digit area code and nnnnnnn is the 7-digit telephone number for the ISDN BRI line. • ss is the Sharing Terminal Identifier (ID), which a two-digit number from 01 to 32. These two digits are normally 01.
• ss is an optional SPID suffix. If present, it is either one digit or two digits. If the optional suffix is one digit, it must be 0, 1 or 2. A different digit is normally used for each of the two SPIDs for the ISDN line. If the optional suffix is two digits, it must be 00, 01 or 02. A different pair of digits is normally used for each of the two SPIDs for the ISDN line. • tt is a 2-digit code from 00 to 62.

Overview The OmniConnect Monitor utility provides various monitoring functions for the OmniConnect/ISDN access device.
7.4. OmniConnect Monitor screens The OmniStart monitor has a number of screens. In most cases you may follow the on-screen instructions. However, this section of the manual documents the description of each screen present in the OmniConnect monitor utility. 7.4.1. OmniConnect Monitor main screen This is the main screen of the OmniConnect monitor utility. You may get complete status of the OmniConnect/ISDN access device from this screen.
The bottom portion of the monitor screen provides ISDN interface status. The main ISDN Link Status indicator provides an indication of whether or not the physical ISDN link and D channel are available or not. In addition, specific B1 and B2 link status indicators indicate the status of the ISDN link (up or down). The link status indicator LEDs also provides the ISDN link speed (56 KBPS or 64 KBPS). There are two counters for the frames transmitted and frames received on the ISDN link. 7.4.2.
7.4.5. Phone extension The Phone Extension screen is used to enter the extension of the user’s phone. The OmniConnect/ISDN access device supports a single extension and therefore, this setting should always be 1. Other versions of the OmniConnect access device series support multiple extensions. In this case, each phone must be assigned a unique extension in order for OmniConnect Monitor to differentiate the phone for which the incoming call is destined. 7.4.6.
7.4.6.2. Ping test The Ping test provides the ability to test connectivity to an Internet host. You may enter the IP address of an Internet host and this test will try to reach that Internet host by sending a Ping (ICMP Echo Request) packet and then waiting for a Ping reply (ICMP Echo Reply) from that Internet host. This test provides you with Internet connectivity information between OmniConnect/ISDN access device and hosts connected on the Internet including the connectivity path through your ISP.
8. Troubleshooting This chapter provides information to aid in the diagnosis of common problems and issues encountered when using the OmniConnect access devices. Included are complete list of ISDN cause codes that the ISDN provider’s switch returns during ISDN call setup. These status and error codes are logged by the OmniConnect/ISDN series access devices and are available using serial console commands. 8.1.
ISDN CONNECTORS DO NOT SEEM TO MATCH The OmniConnect/ISDN series access devices connect to the ISDN line with a straight-through ISDN BRI cable. This cable is fitted with both RJ45 (eight conductors) and RJ14 (six conductors) ends. Connect the RJ45 end of the cable into OmniConnect access device, and the RJ14 end (the smaller one) into the ISDN network interface jack. In lieu of an ISDN cable, a straight through 10Base-T cable with RJ45 jacks may be used.
8.2. Software OMNISTART CONFIGURATION FAILS Check that there is a valid and active 10Base-T connection between the station with OmniStart installed and the OmniConnect access device. The green LED on the access device corresponding to the 10Base-T connection must be lit. Check that TCP/IP protocol software is installed on the PC and the PC has been restarted so that the installation takes effect. The configuring PC must have an active 10Base-T LAN-based TCP/IP connection.
SOME APPLICATIONS DO NOT RUN WITH OmniNAT CONFIGURED There are several applications that are incompatible with the Network Address Translation (NAT) protocol. The OmniNAT implementation is completely compatible with, and adheres to all the relevant RFCs. However, the NAT protocol makes some assumptions regarding IP traffic which are not always true, causing several applications to misbehave when used with NAT.
Extension 1 is assigned the phone number 408.555.2121 and the settings for this phone number are to generate an urgent ring tone and then forward after 4 rings to a specified forward number. The Caller ID number 510.555.2222 is also assigned to extension 1 and the settings for this calling number are to generate a normal ring tone and not to forward the call. If an incoming call from 510.555.2222 is detected, the Caller ID settings will be used to ring the phone in a normal fashion.
