INSTALLATION Issue 2, May 1990 INTER-TEL PRACTICES GMX-48 INSTALLATION & MAINTENANCE Data Port Module 7.9 24-line keysets may be equipped with optional Data Port Modules (part number 828.1094). The Data Port Module contains a four-conductor modular jack that can be used to connect either a data device (such as a personal computer with a direct-connect modem) or an LRA and an external signalling device (such as a loud bell, horn, flashing light, etc.) to the keyset. 7.10 Install the Data Port Module as outlined be- low. For a diagram, see Figure 3-20 on the next page. 0) (2) (3) (4) (5) (6) (7) Remove the keyset baseplate by pressing on the top edge of the baseplate to release the tab, and by pulling the plate off. Unplug the line cord from its modular jack. Remove the lo-pin shorting plug located on the keyset control board. NOTE: The back cover of the keyset does not need to be removed in order to reach the shorting plug. Save the shorting plug by taping it to the bot- tom cover of the keyset or to the inside of the baseplate. The plug must be replaced if the Data Port Module is later removed. Align the Data Port Module over the appropri- ate screw holes (see Figure 3-20) on the back cover of the keyset and insert the screws (do not over tighten). Plug the Data Port Module cable into the pins on the KSU Control Board where the shorting plug was previously located. Make sure the cable connector is securely seated. Place straps SPl, SP2, SP3, and SP4 on the Data Port Module in the appropriate posi- tions. Depending on how the Data Port Mod- ule will be used, refer to one of the three possible settings outlined in Figure 3-20. (8) If connecting a modem-equipped data device, re- fer to paragraphs 7.11 through 7.13. . If connecting a loud ringing adapter and an exter- nal signalling device, refer to paragraphs 7.14 through 7.16. 7.11 To Connect A Modem-Equipped Data Device: The optional Data Port Module can be used to con- nect a data device (such as a personal computer) equipped with a direct-connection modem to a 24-line keyset. The data device can be used with the keyset to communicate with remote data equipment over CO. lines or intercom channels. The data de- vice’s modem must be externally powered (or capable of operating on 20mA of loop current) and have an RJll C.O. line interface. 7.12 The data device can be activated using the key- set or an auto-dial modem. It is disconnected when one of the following occurs: when the modem at- tached to the keyset disconnects from the call, when the called modem disconnects from the call, or when the data connection is transferred to the keyset’s pri- mary voice path and the call is disconnected. (For complete details on using an attached data device, ei- ther with or without a secondary voice path installed, refer to page 4-90 in FEATURES.) 7.13 (1) (2) (3) Install the data device as follows: Insert the modem line cord (which would nor- mally be connected to a CO. jack) into the modular jack on the keyset’s Data Port Mod- ule. Ensure that the straps on the Data Port Mod- ule are set to the proper data device positions (either with a secondary voice path or without a secondary voice path). Refer to Figure 3-20 on the next page. Plug the keyset linecord into the keyset’smod- ular jack and reattach the baseplate. Page 3-42

INSTALLATION Issue 2, May 1990 ‘. INTER-TEL PRACTICES GMX-48 INSTALLATION & MAINTENANCE 7.14 To Connect A Loud Ringing Adapter (LRA): The optional Data Port Module can be used to con- nect external signalling equipment such as loud bells, horns, flashing lights, etc. to a 24-line keyset. This application is useful in areas where the normal ring tone of the keyset cannot be heard, such as ware- houses and loading docks. The signalling device fol- lows the normal ringing patterns of the keyset. NOTE: Since handsfree intercom calls may be diffi- cult to hear in noisy areas, keysets with LRAs in- stalled should be programmed for handsfree disable so that users are alerted to incoming intercom calls by continuous double ring tones. (Refer to FEATURES, page 4-45.) 7.15 An electromechanical LRA device is placed between the keyset Data Port Module and the exter- nal signalling equipment to provide the necessary in- terface relay. Refer to page 2-12 for LRA device specifications and recommendations. A diagram of a typical set-up is shown in Figure 3-21 below. 7.16 Install the LRA as follows: (1) Using 24AWG wire, connect the LRA device input (coil circuit) to the RED and GREEN wires on a modular jack assembly. Some de- vices require that polarity be observed be- tween the LRA input and the modular jack. NOTE: In order for the LRA deyice to operate properly, the maximum resistance from the modular jack to the LRA should be kept under 100 ohms. Attach a mod-to-mod line cord to the modular jack assembly and to the modular jack on the keyset’s Data Port Module. Ensure that the straps on the Data Port Mod- ule are set in the proper LRA positions. Refer to Figure 3-20 on the previous page. Connect the LRA device output (contacts) to the signalling device according to the man- ufacturer’s instructions. Use the appropriate gauge wire for handling the current/voltage rating of the signalling device. Plug the keyset line cord into the modular jack on the back of the keyset and reattach the baseplate. FIGURE 3-21. LRA SET-UP KEYSET DATA MODULAR JACK PORT MODULE ASSEMBLY LRA DEVICE (e.g., relay) SIGNAL DEVICE (e.g., bell) NOTE: Each time the keyset rings, the Data Port Module provides 20-26mA of loop current to the LRA. This causes the LRA contacts to close and activates the signalling device. The LRA is not affected by the ring tone or the ringer volume of the keyset. The LRA must be capable of operating on 20mA current (approximately 20VDC). Page 3-44
INTER-TEL PRACTICES GMX-48 INSTALLATION & MAINTENANCE INSTALLATION Issue 2, May 1990 B. DIRECT STATION SELECTION/BUSY LAMP FIELD (DSWBLF) UNIT INSTALLATION 7.17 Up to five DSS/BLF Units can be installed on the system. If desired, all five units may be on the KSU Control Board or on the same Expansion Mod- ule. Each unit has 60 keys for directly accessing up to 48 intercom numbers and up to 5 hunt group num- bers. 7.18 As with keysets, DSWBLF Units require three-pair cabling. After they are installed, the DSS/ BLF Units must be assigned in database program- ming to be used along with designated keysets. 7.19 Unpack and inspect the DSS/BLF Units be- fore installing them. Each DSS/BLF Unit is shipped with a 7-foot line cord. 7.20 For each DSS/BLF Unit: (1) Before connecting the DSS/BLF Unit to the KSU, measure the voltage on the RED termi- nal of the modular jack assembly with respect to the GREEN terminal. (Ihe “common” probe of the voltmeter is placed on the GREEN terminal.) It must measure +3OVDC (+2.OVDC). If -30VDC is mea- sured, check the cabling for a reversed pair. CAUTION If the power pair (WlBL, BL/W) is reversed, in- stalling a DSS/BLF Unit will open the fuse on the KSU Control Board or Expansion Module. This affects operation of all keysets and DSS/ BLF Units connected to the board or module. (2) Mount the modular jack assembly on the wall. (3) Perform the DSWBLF Unit self-test: a. Disassemble the DSS/BLF Unit by remov- ing the four screws on the bottom of the unit. -b. Locate the four DIP switches in the lower- right comer of the unit’s control board. c. Set DIP switch 1 to the TEST (closed) posi- tion. Reassemble the unit without replac- ing the screws. d. Plug one end of the line cord into the mod- ular jack assembly and plug the other end into the KSU jack on the bottom of the DSWBLF Unit. The system automatically tests the unit’s processor. NOTE: If the test fails, you will not be able to continue to the next step; the unit will ig- nore all input. Remove and replace the line cord. If the test fails again, replace the DSS/BLF Unit. e. Test the keys by pressing them one at a time, starting with the key in the upper-left comer and continuing from the top to the bottom of each column. As each key is pressed, the LED lights and remains lit. If an LED does not light, either the key was pressed out of order, the key is faulty, or the LED is faulty; the DSS/BLF Unit must be replaced. f. Open the DSS/BLF Unit again and return DIP switch 1 to the RUN (open) position. NOTE: The other three DIP switches (2-4) are not used. g. Reassemble the DSS/BLF Unit and re- place the screws.

INSTALLATION Issue 2, May 1990 ‘.. INTER-TEL PRACTICES GMX-48 INSTALLATION & MAINTENANCE C. SINGLE-LINE SET AND PLAYBACK DEVICE INSTALLATION Single-Line Sets 7.21 The types of single-line sets listed below can be used on the GMX-48 System. They are connected to Accessory Port Modules (APMs). If the single-line set has an AC ringer, the strap on the corresponding APM circuit must be placed in the AC position (un- less the single-line set is an off-premises station con- nected through an HVRA Unit, in which case the APM strap must be set in the DC position). If a single- line set has a DC ringer, the strap must be in the DC position. Refer to Figure 3-18 on page 3-36 for strap settings. station instrument that operates as a regular station or with a playback device that answers the call, then disconnects to transfer the call back to the hunt group. Refer to FEATURES, page 4-17, for more in- formation. 7.27 With the Advanced software package, playback devices may also be used in conjunction with theauto- mated attendant feature. In this situation, the play- back device answers the call and plays a prerecorded message. After the message, the caller is discon- nected from the automated attendant and hears three quick tones followed by silence. The caller may then dial an intercom number or a hunt group pilot number. Refer to FEATURES, page 4-13, for more information. 7.22 Single-Line Instrument (SLI): An internal strap can be moved to set the ringer for AC or DC. (An AC ringer is required if the single-line set is used as an off-premises station.) Be sure the strap is set correctly for the installation; incorrect installation will cause damage to the set. Installation 7.28 Inspect the SLIs before installing them. If any parts are damaged, contact Customer Service. To in- stall a single-line set or a playback device: 7.23 Industry-standard single-line DTMF set: If single-line DTMF sets are used as off-premises sta- tions, they must be equipped with AC ringers. When used on premises, single-line DTMF sets may have AC or DC ringers. 0) Playback Devices 7.24 Playback devices can be used in place of single- line sets on APM circuits. These devices answer an in- coming call, play a recorded message, and automatically disconnect from the call. They are in- stalled like single-line sets, using the same cabling and modular jack assemblies. (2) 7.25 If the playback device responds to AC ring sig- nals, the APM circuit must be strapped for AC ring- ing; if the device responds to DC ring signals, the strap must be set for DC ringing. (Refer to Figure Fig- ure 3-18 on page 3-36.) A playback device uses the intercom number that is associated with its SIN circuit. 726 With the Advanced software package, playback devices may be used with hunt groups to speed call processing. Hunt groups can have two types of special stations: announcement stations and overflow sta- tions. Either type of station can be equipped with a (3) (4) (5) Page 3-46 . rf installing an SLI: a. Remove the baseplate and open the phone to expose the control board. b. Place the AC/DC strap in the desired posi- tion. (Refer to Figure 3-22 on the following page.) C. Reassemble the phone. Before connecting the single-line set or play- back device to the KSU, measure the voltage on the RED terminal of the modular jack as- sembly with respect to the GREEN terminal. (Ihe common probe of the voltmeter is placed on the GREEN terminal.) It must measure -30 (22VDC). If +3OVDC is measured, check the cabling for a reversed pair. Mount the modular jack assembly on the wall. Plug one end of the line cord into the modular jack assembly and the other end into the jack on the single-line set or playback device. To wall mount an SLI, refer to the instructions given for wall mounting the keysets on page 3-41. : : :

INSTALLATION Issue 2, May 1990 INTER-TEL PRACTICES GMX-48 INSTALLATION 8i MAINTENANCE 8. AUTO-ANSWER MODEM INSTALLATION 8.1 Remote programming of the system requires in- stallation of a customer-provided auto-answer mo- dem. The modem is connected to an RS-232-C port on the KSU and directly to an APM circuit or a dedi- cated C.O. line. Refer to page 2-16 for RS-232-C pin- out and modem specifications. 8.2 When the programmer accesses the modem, the modem automatically sends modem tone. The programmer may then log on to the system and per- form any necessary programming functions. When finished, the programmer hangs up and the modem is disconnected. The modem is installed as follows: (1) (2) (3) To connect the modem to an APM circuit: (5) Test the modem installation by placing a call to the modem’s assigned telephone number. When answered, the modem should send mo- dem tone. a. For modems that respond to AC ringing, set the strap on the APM to the AC ringer setting. Or, if the modem responds to DC ringing, set the strap to the DC ringer set- ting. (Refer to Figure 3-18 on page 3-36 for strap locations.) 9. SMDR/SAR OUTPUT DEVICE b. Run station cabling as you would for a single-line set. The modular jack assembly should be close to the KSU to allow the modem to be connected to an RS-232-C port. 9.1 The output device(s) the station message de- tail recording (SMDR) and system activity report (SAR) features must meet the requirements and match the RS-232-C pinout described in SPECIFI- CATIONS on page 2-16. The cable(s) between the device(s) and the KSU must not be longer than 50 feet (15 meters). 9.2 To connect an output device to the KSU: c. Connect the modem line cord (with RJll connector) to the modular jack assembly. To connect the modem to a C. 0, line: Terminate tip and ring from an available (or switchable) C.O. line onto a four-conductor modular jack assembly. Then, connect one end of a mod-to- mod line cord to the modem RJll connector and connect the other end to the modular jack assembly. Match the baud rate of the modem to that of the desired RS-232-C port. Refer to page 2-16 for the proper baud rate settings. Plug in the modem’s AC power cord and turn on the AC power to both the modem and the (1) (2) (3) (4) Page 3-48 system before connecting the modem RS-232-C cable to the KSU. This prevents electrical surges from being transmitted by the interface. (4) Carefully connect the modem KS-232-C cable to the desired RS-232-C connector on the KCB or APM. NOTE: The modem must be configured for connection to a computer interface. For de- tails, refer to the manual that accompanies the modem. INSTALLATION Match the baud rates on the output device and the port to which it will be attached (KCB or APM). Refer to page 2-16 for the proper baud rate settings. 7lrm on the AC power to both the device and the system before connecting the RS-232-C cable to the KSU. This prevents any electrical surges from being transmitted by the interface. Carefully connect the RS-232-C interface cable from the device to the appropriate RS-232-C connector (KCB or APM) on the KSU. To set the parameters for the SMDR and SAR outputs, refer to PROGRAMMING.
INTER-TEL PRACTICES GMX-48 INSTALLATION & MAINTENANCE INSTALLATION Issue 2, May 1990 10. EXTERNAL MUSIC SOURCE INSTALLATION 10.1 A jack on the bottom edge of the KSU is the input for an optional external music source (radio, tape player, etc.). For more information, see SPECI- FICATIONS, page 2-7. NOTE: In some circumstances, there may be broad- cast restrictions associated with the music. Check with the music’s original distributor and/or the radio station for copyright and broadcast restrictions con- cerning background music and music-on-hold. 10.2 If using a radio as the music source, place it 5 to 10 feet away from the KSU to avoid RF1 generated by the KSU. Lf the radio is placed more than 10 feet away from the KSU, use twisted pair cable. For better re- ception, a radio with an external antenna is recom- mended. 10.3 (1) (2) To install the external music source: On the KSU Control Board: (5) EITHER, place the music-on-hold (MOH) ON/OFF strap in the ON position (over the left two pins) to enable music. When C.O. calls are placed on hold, the caller hears music. (6) OR, place the music-on-hold (MOH) ON/ OFF strap in the OFF position (over the right two pins) to disable music. When C.O. calls are placed on hold, the caller does not hear music. (7) NOTE: If an external music source is con- nected, the position of the music-on-hold strap will not affect the ability of keyset users to re- ceive background music. Also, regardless of the strap location, internal station users will hear music when placed on hold by another station or when camped on. (8) If music-on-hold is enabled, set the MOH HI/ LO strap in the desired position. For a lower MOH volume level, set the strap in the LO po- sition (over the left two pins). For a higher (3) (4) MOH volume level, set the strap in the HI po- sition (over the right two pins). . Attach an x-inch, two-conductor, mini-phone plug to one end of a 5- to lo-foot (1.5- to 3.0-meter) length of coaxial cable. Or, if the ra- dio is placed more than ten feet away from the KSU, use twisted pair cable. EITHER, connect the other end of the cable to the speaker output terminals of the music source. OR, if the music source has an earphone jack, attach an x-inch mini-phone plug (or other specified connector) to the other end of the cable, and plug it into the earphone jack on the music source. . NOTE: lf the earphone jack is “padded” so that the optimal volume level cannot be reached, the first procedure above (beginning with EITHER) may be more effective. Plug in the AC power cord for the music source. DO NOT use the outlet that is being used for the KSU. Turn on the AC power to the music source. Insert the x-inch mini-phone plug into the jack labeled MUSIC on the bottom of the KSU. From a keyset: EITHER, select a C.0 line and dial the tele- phone number of one of the other lines to call back into the system. Put the call on hold to hear the music. OR, place an intercom call to another station. Put the call on hold to hear the music. While listening to music-on-hold, adjust the volume on the music source to a level within the range of the automatic gain control circuit (slightly past the point where the volume level no longer increases). The optimal input level is 0.775VRMS (OdB). ’ Page 3-49

INTER-TEL PRACTICES GMX-48 INSTALLATION & MAINTENANCE INSTALLATION Issue 2, May 1990 12. POST-INSTALLATION CHECKLIST 12.1 To ensure that the system has been installed properly, review the installation outline on page 3-3. Then, review the items on the following list as a final check. - - - KSU, MDF, and station locations and cable runs meet environmental requirements, and cable lengths are within loop limits. Bridging clips are installed where required on all MDF blocks. Gas discharge tubes with silicon avalanche sup- pressors are installed on the C.O. and the OPX lines for lightning protection. Also, if extra pro- tection is desired, the cable between the tele- phone company RJ-type block (or RJ-type jacks) and the gas discharge tubes is at least 75 feet long. If off-premises stations are used, HVRA Units, power supplies, ring generators, OPX or cus- tomer-provided lines, and OPX repeaters (if needed) are connected at the MDF. The KSU, HVRA(s), and 48VDC power supply(s) are attached to an approved earth ground. The KSU power supply is plugged into an isolated, dedicated AC outlet, and no other equipment has been plugged into the same outlet. An extension - - - - - cord wasnot used. A voltage surge/spike protector is installed to reduce the effects of AC voltage surges and spikes that can cause system malfunc- tions, false logic, and/or damage to the electronic components. Power supply and database back-up battery volt- ages are in tolerance. The battery strap (JMP 1) in the KSU is placed in the A position (over the low- er two pins). Amphenol-type connectors and station instru- ment line cords are all connected securely. All keyset, DSS/BLF Unit, single-line set, and play- back device stations are working properly. All optional equipment is properly installed and working correctly (for example, printer has paper and ribbon, radio is tuned to a station, auto- answer modem connected to the RS-232-C port is hooked up and working properly, etc). C.O. dial tone is present and calls can be placed and received using all lines. (Refer to FEA- TURES and PROGRAMMING for initializing the system and for programming outgoing access, allowed answer, and ring in.) After programming the system, the database is backed up using a reliable storage device. (Refer to the PROGRAMMING section for details.) Page 3-51
