DX-80 Installation & Maintenance 1. OVERVIEW The Comdial DX-80 is a fully digital hybrid key telephone system. The DX-80 uses “loop start” central office (telephone company) line interfaces, and a mix of analog and digital extension ports to provide office communications and connectivity to the Public Switched Telephone Network (PSTN).
Overview Device Name KSU1 Part # 7201 Characteristics 8 digital extension ports. 4 analog device ports. 4 CID-ready CO line ports. 2 music source inputs, can be assigned as desired to CO lines for hold music/ messages. 1 power failure port (CO line 1). 1 control contact (LBC, Gate, External Page Control). 1 external paging equipment interface. 2 serial ports. PC-DBA programming. SMDR (Station Message Detailed Recording).
DX-80 Installation & Maintenance 1.2 Configuration The Comdial DX-80 platform is comprised of one full-featured key telephone model and two modular KSUs (Key Service Units). Several modules are available for enhanced system applications and configuration expandability. 1.2.1 KSU1 COMPONENTS The CPM (Central Processor Module) is installed inside of KSU1 to the 408M ribbon cable J4 (also labeled “To CPM”).
Overview 1.2.3 VOICE PROCESSING MODULES The DX-80 provides several voice processing (or voice mail) options. The optional voice processors that you can add to the DX-80 are fixed system resources that do not require peripheral device ports (analog or digital). This significant advantage means that the DX-80 VP options can be added to any DX-80 configuration without “port loss” thus eliminating the ill effects of reducing the overall capacity of the system when the voice processor is connected.
DX-80 Installation & Maintenance 1.2.
Overview Figure 1-1 DX-80 Key Service Unit (KSU) You can remove or reposition three panels installed over various KSU openings to accommodate exterior connection requirements. You can remove one panel to route a serial cable through the KSU outer housing for connection of ancillary SMDR equipment. You can remove another panel to route a serial (NULL Modem) cable through the KSU outer housing for direct connection of a PC for on-site PC-DBA programming.

(The 408M peripheral processor is operating when the heartbeat LED is flashing.) The KSU1 operation LED (located next to the power switch) is tied to the 408M heartbeat LED.
Overview Each digital port (connects to Digital Executive Telephones and DSS Consoles) is comprised of a proprietary octal ASIC (Application Specific Integrated Circuit) transceiver. There are three data channels in operation at each digital port via the octal transceiver. One channel is used for call processing control of digital terminal functions/operations and two channels are used for the digital voice channel requirements.
DX-80 Installation & Maintenance The fourth CO line port is equipped with CNG Fax Tone Detection circuitry. When programmed as a “FAX” line, this circuit automatically engages the FAX tone detector. If FAX tone is detected, the system routes the call to the analog port designated as the destination for fax calls. Each digital port (connects to Digital Executive Telephones and DSS Consoles) is comprised of a proprietary octal ASIC (Application Specific Integrated Circuit) transceiver.
Overview The APM4 provides DTMF receivers for each analog port. Ancillary analog devices connected to APM4 analog ports must generate DTMF signaling. CAUTION Pulse (rotary-dial) telephones/equipment are not supported. All connections are via RJ-11 connectors along the bottom edge of the module. KSU1 is delivered with one APM4 installed on ribbon connector J5 as standard equipment. APM4’s may be installed on 408M/E-J5 (standard in KSU1:408M-J5), 408M/E-J2, or 408M/E-J3.
DX-80 Installation & Maintenance 1.9 DPM8 (Digital Port Module - 8 Circuits) The DPM8 module expands the DX-80 system capacity of digital ports DET (Digital Executive Telephones) and DSS consoles. Each digital port is comprised of a proprietary octal ASIC transceiver. There are three data channels in operation at each digital port via the octal transceiver.
Overview 1.10 COM4 (Central Office Module - 4 Circuits) The COM4 module is installed in the dedicated position via J1 of the 408M/E. The COM4 interfaces four loop-start CO lines. Since one COM4 may be installed in KSU1 and one COM4 may be installed in KSU2, you can expand the DX-80 system CO line capacity to support up to 16 CO lines.
DX-80 Installation & Maintenance 1.11 MDM (Modem Module) The 7249 Modem Module is a self-contained integrated modem unit that is installed at JP5 and JP6 in the upper right corner of the CPM. The integrated MDM allows you to access the system programming and remote maintenance utilities from an off-site location (password verification is required). Figure 1-8 MDM (Modem Module) When the MDM is installed, you can program the system remotely using PC-DBA.
Overview 1.12 AAM (Automated Attendant Module) The Automated Attendant Module is a self contained integrated module that enables automatic answering of selected CO lines and a single-level menu for greeting callers and routing them to DX-80 system destinations. The AAM can handle all call traffic or act as a backup to the primary answering system attendant. Figure 1-9 AAM (Automated Attendant Module) The AAM is installed at JP3 and JP4 of the CPM (centered above the board).
DX-80 Installation & Maintenance The display also provides a visual reference to call progress and call duration, as well as time and date information. The display enables the user to send and receive visual advisory and callback messages. Users may select from six pre-programmed messages (i.e., “IN A MEETING,” “OUT OF OFFICE”), or they may create a custom message. Callers from other DETs to an extension with a message active will receive the visual advisory message on their LCD display.
Overview 1.14 DSS (Direct Station Selection) Console The DSS console is a digitally interfaced component of the DX-80. It connects to the system via any available digital port (408M/E or DPM8 digital port). The DSS is equipped with 60 programmable buttons.

DX-80 Installation & Maintenance 4. TROUBLESHOOTING INSTALLATION ISSUES This chapter outlines the most common installation problems for the DX-80, and provides a corrective action addressing each issue. 4.1 Corrupted Database on Initial System Setup SOLUTION: DX-80 Power-Up Initialization You must successfully initialize the DX-80 system during start up procedures for the system to operate properly.
Troubleshooting Installation Issues 4.2 Adding Hardware to an Existing System (Making Sure the DX 80 Recognizes It) SOLUTION: Follow the steps required when adding hardware to an existing system. When you add any optional expansion/circuit modules (COM4, DPM8, APM4, In-Skin Voicemail, or Modem) to either KSU1 or KSU2, you must follow certain procedures to ensure the DX-80 configures itself properly with the newly added equipment. These procedures include performing a cold start/initialization.
DX-80 Installation & Maintenance • perform a cold start initialization (which loads a default database, writing over your custom database), and then • reload the saved database over the default database. Follow the detailed procedure in Section 4.2, Adding Hardware to an Existing System (Making Sure the DX 80 Recognizes It). If you have an existing database, and do not have access to PC-DBA, you must program using the telephone.
Troubleshooting Installation Issues 4.4 Invalid Entries Calling a Busy Station; Issues with Multiple Mailbox Greetings SOLUTION: The following items should be applied to all DX-80 (PC8 In-Skin) Voice Mail Systems; build 8.5.9 and earlier. CAUTION All characters must be entered as shown for proper programming. Commands in bold indicate changes to previously documented material, and are not to be entered as bold. 1. Add the new TRANS.TXT file – 8.5.9.
DX-80 Installation & Maintenance a9byd2=3102 a9byd3=3103 a9byd4=3104 a9byd5=3105 ;UCD overflow 2 for UCD groups 1-5 a9byd91=3201 a9byd01=3202 a9byd*1=3203 a9byd#1=3204 a9byda1=3205 ;UCD overflow for all other groups a9bydx= 2. Remove Mail Box 157. This is a voice mail port and cannot be used as a mail box. 3. Remove Custom 16384 from voice mail – it adds an asterisk (*) to the end of transfers. This causes problems with analog phones (phone rings once but are dead air when answered). 4.
Troubleshooting Installation Issues 4.6 Ringing a Group Of Phones Before Routing the Call to Auto-Attendant SOLUTION: Implement delayed ringing to Voice Mail, AutoAttendant. Note that UCD groups 1- 5 (410-414) are used for the DX-80’s built in UCD functionality with the Inskin Voice mail system. To implement delayed ringing, perform the following steps. 1. Set up a UCD group. Use Hunt group 6 through 23 (415-432) when using the inskin voice mail.
DX-80 Installation & Maintenance 2. Set up the CO line Answering Position. • Make the following UCD Group the only Destination for Day / Eve, and • Set Pre-CFW NoAns to NULL. 4.6.1 INSKIN VOICE MAIL If you use UCD groups 6 through 23, you do not have to modify TRANS.TXT unless you want a specific routing box or mailbox to answer. If you use UCD group 1 through 5, you must modify the TRANS.TXT to route the integration to the proper Routing Box/greeting desired.
Troubleshooting Installation Issues Example (PC8): UCD group 6 (415) will re-route to VM with the String; a9b2d63. This digit string will get a success on the rule: a9bydz= and will follow the voice mail’s Line Information screen to answer the call based on Day, Lunch or Night. So, if you need the voice mail to answer with a different greeting, (i.e., routing box 805) you must add a line to the TRANS.TXT above the following rule: a9byd63=805 a9bydz= 4.6.
DX-80 Installation & Maintenance When the DX-80 forwards a call to Voice Mail hunt group 24 (dir 433) the following in-band digits are sent to voice mail.
Troubleshooting Installation Issues 2. Assuming that: • Company A will be using Routing Box 800 to answer incoming calls; • Company B will use Routing Box 810, and • Company C will use Routing Box 820. Add the following lines to the top of the TRANS.TXT file. a7byczd740 a7byczd741 a7byczd742 a7byczd743 a7byczd744 a7byczd745 a7byczd746 = = = = = = = 800 800 810 810 810 820 820 a7byczd747 = 820 Example 2: Incoming CO lines ring a UCD group first then re-route to Voice Mail if no one answers. 1.
DX-80 Installation & Maintenance The following line is needed at the top of the TRANS.TXT file. a9b2d63 = 800 The following UCD group 7 (dir 416) will ring all phones approximately three to four rings, then reroute to Voice Mail with the following in-band digits. a9b2d73 The following line is needed at the top of the TRANS.TXT (C:\VM\TRANS.TXT) file.
Troubleshooting Installation Issues The following UCD group 8 (dir 417) will ring all phones approximately three to four rings then ReRoute to Voice Mail with the following in-band digits a9b2d83. The following line is needed at the top of the TRANS.TXT file.
DX-80 Installation & Maintenance 4.8 Setting Up Message Delivery to a Cell Phone SOLUTION: External Transfers with Voice Mail 1. If the system has In-Skin or analog voice mail, and uses Centrex transfer on the same CO line, go to the Call Transfer Information screen in PC-DBA. Then enter the following values in the External column.
Troubleshooting Installation Issues 2. Next, you must enable ECF. Go to the DX80 Extension – Category 2 PC-DBA screen and enter Y in the ECF Operation field. 3. Finally, using the phone dial into the programming mode and enter 01-(101~156)-18. The range of numbers in the middle of this command represent the station number. So, to program station 102 you would enter 01-102-18, to program station 123 you would enter 01-123-18, etc. 4.
DX-80 Installation & Maintenance 1. Place line 4 (743) into CO group2 (800). 2. From the Fax machine, go off hook and dial 800 (be sure you are accessing line 4). Then dial a valid number. You must dial out on that line /(line group) before programming the hot line (dial 740 for line 1, 741 for line 2, 742 for line 3 etc.…). 3. Program a System Speed dial bin with a pause. To do this, you can use PCDBA or program using the phone. Using PCDBA Go to the DX80 PC-DBA System Resource SPD. No.
Troubleshooting Installation Issues Save 500~699 [System Speed dial bin number] Show Chg Feature 7 0 Save 4. From the fax machine extension, go off hook and program the fax extension as a hot line to that system speed dial bin number. Dial (# 9 * 500 0). Confirmation tone is heard. 5. Every time the fax machine goes off hook, line 4 will be accessed. To cancel do a hook flash and dial # * 9 *. 4.
