1.3 Accessory Information

The digital telephone system is capable of supporting several accessory software and hardware devices. You can add voice mail, industry standard telephones, and headset capabilities to your digital telephone system.

1.3.1 The Analog Terminal Interface

By employing the Analog Terminal Interface device (ATI-D), the digital telephone system can support the operation of the following accessories:

ExecuMail and Versatile Voice Processing,

•

Industry-standard telephones and telephone devices.

•

For more information on the ATI-D, see section 2.19.2, Installing The Analog Terminal Interface.

1.3.2 Headset Operation

The Comdial DigiTech speakerphones with product codes of 7700S, revision H and earlier, include a built-in headset port. Speakerphones with a revision of I and later and Impact LCD speakerphones with product code 8024S provide an auxiliary jack for headset interface.

Contact your Comdial Inside Sales Representative for a list of compatible headset manufacturers.

NOTE: The system delivers subdued off-hook voice announce (SOHVA) messages to the headset

port. Because a telephone headset exhibits a coupling effect between the ear piece and the microphone, it may allow the outside party to hear the SOHVA message.

Introducing The DSU 1 – 5

Digital Telephone System IMI66–107

1.3.3 Battery Back Up

You can install an optional battery backup that provides power to the system in the event of a power failure. For more information, see section 2.20.1, Installing The Battery Backup.

1.3.4 DSS/BLF Console

You can add a separate DSS/BLF console to provide additional DSS/BLF buttons to a particular station (such as an attendant). These additional DSS/BLF buttons work just like the DSS/BLF buttons on the telephone. For more information, see section 2.6, Installing The DSS/BLF Console.

1.3.5 Caller ID

Using the Caller Identification Interface (product code CID08), the digital telephone system provides caller ID information as part of the SMDR printout and as ASCII data input for use with personal-computer-based application programs.

1.3.6 Tracker

With Tracker you can send messages to Tracker Pagers assigned to a station extension number. When the pager is activated the user reads the message on the pagers LCD display. The system delivers alpha/numeric or numeric-only messages depending on the Tracker Model being used.

1.3.7 DVA

Digital voice announcing uses a hardware peripheral device (product code DVA01) connected to a digital station port to play recorded messages during an in-progress call. The DVA stores the messages in its memory for recall when needed.

1.3.8 DIU

The Data Interface Unit (DIU) is a device connected to a digital station port of a DSU. The DIU provides connections for a digital multiline telephone and another device such as a industry standard telephone (IST), FAX, or modem. The DIU swithces the voice path from the DSU to either the digital telephone or the IST by pressing a button on the digital telephone.

1 – 6 Introducing The DSU

IMI66–107 Digital Telephone System

1.4 Hardware Summary

The digital telephone system consists of an electronic Digital Service Unit (DSU)usually referred to as common equipmentoptional expansion modules to extend station and line capacities, dedicated digital electronic key telephones, and interconnecting wiring consisting of small, 2- or 4-conductor, twisted-pair cable. The digital telephone system supports all Comdial proprietary digital telephone models.

NOTE: Sxxxx software only supports DigiTech telephones; Ixxxx software supports all digital

telephones.

The station and line capacity of the base unit and optional expansion module are detailed in the following chart.

1.5 Common Equipment Description

The common equipment base unit is a fully electronic device. It is essentially a special purpose computer system acting as a communications controller between central office (CO), private branch exchange (PBX), or CENTREX supplied lines and the proprietary digital telephone stations. The software design of the common equipment provides complete system support and great flexibility of operation.

The system is fully digital with two usable time slots available for each station. Digital information is computer-encoded voice transmission and control signals. After a computer translates analog voice transmissions to digital information, the digital signals travel through time division multiplexing (TDM) highways. The TDM highway can transmit several signals over a single pair of wires at the same time. A system clock partitions TDM information into time slots. A time slot is a portion of time assigned to a particular position of the system clock. Each time a particular clock position is reached, the computer reads information associated with that position. As the system clock goes through its cycle, the computer passes digital information between pieces of equipment sharing time slots.

The common equipment consists of a base unit, which provides complete feature support, and optional expansion modules for additional lines and stations. It is contained in a contemporary metal housing designed to be inconspicuous in a modern office environment. It is engineered to be wall or rack mounted.

2.1 Mounting Considerations

The following requirements will help you to install the digital telephone system.

Locate the equipment cabinet within four feet of an AC electrical outlet dedicated

•

exclusively to the use of this equipment. The outlet must be a 117 VAC 15 AMP circuit with a third-wire ground supplied to a standard electrical outlet (NEMA 5–15R).

Mount the common equipment within 25 feet of the TELCO/PBX jacks. The recommended

•

nominal distance is 7 feet. Choose a secure and dry mounting location that has adequate ventilation. The temperature

•

range of the location must be within 32-122 degrees F (0-50 degrees C) and that the relative humidity is less than 90 percent, non-condensing.

If the mounting surface is damp or if it is made of concrete or masonry material, you must

•

attach a backboard to the mounting surface for mounting the common equipment. Suitable mounting backboards are available commercially or you can construct one from 3/4-inch plywood by cutting it to size.

2 – 4 Installing The DSU

IMI66–107 Digital Telephone System

2.1.1 Tools And Hardware

You will need the following tools and materials to install the common equipment.

Fasteners—wood screws (1/4 x 1-inch round head), toggle bolts, or wall anchors,

•

Screwdriver—to match fasteners,

•

Electric drill—if prepared holes are required,

•

Connecting tool—for fastening wires to a type-66 connector block,

•

Crimping tool—for 623-type modular plugs,

•

Volt/Ohm Meter.

•

2.1.2 The Underwriters Laboratories Installation Notice

Per The Underwriters Laboratories standard 1459, 2nd edition, be aware of the following precautions when installing telephone equipment that is to be directly connected to the telephone company network:

Never install telephone wiring during a lightning storm,

•

Never install telephone jacks in wet locations unless the jack is specifically designed for

•

wet locations, Never touch uninsulated telephone wires or terminals unless the telephone line has been

•

disconnected at the network interface, Use caution when installing or modifying telephone lines.

•

2.1.3 Hybrid Installation

Whenever a programmer assigns lines to line groups, the digital telephone system automatically assumes the hybrid mode. Your local telephone company may charge a higher monthly fee for operation of a hybrid system; therefore, the FCC requires that you report the equipment-type category designation number (KF for key system, MF for hybrid system) to the telephone company at the time of installation.

2.2 Mounting The Cabinet

After thoroughly reviewing Section 2.1 and fully understanding its subject matter, use the following procedure to mount the common equipment cabinet

1. Unpack and carefully inspect all equipment for shipping damage. Notify the shipper immediately of any damages that you find. Verify that the packages contain all parts and accessories needed for proper installation and operation.

2. If the mounting location requires a backboard, attach it securely to provide a stable mounting surface for the equipment.

3. Refer to Figure 2-1 or to the PP032-001 mounting template included in the literature that accompanies the common equipment cabinet for the locating dimensions required for the three mounting screws, and mark their locations on the mounting surface.

4. Drill holes in the mounting surface of a proper size to accommodate the hardware being used. If necessary, prepare these holes with inserts, anchors or other attachment devices as dictated by the type of mounting surface.

5. Insert the two top screws into the mounting surface and tighten them to within approximately 1/8-inch of the surface.

6. Hang the cabinet on the top screws using the mounting holes located on the rear of the cabinet. Note that these holes are elongated with an enlargement at one end. This feature allows the cabinet to snap down on the screws to secure the mounting when the cabinet is hung on them.

7. Insert a third screw through the mounting tab located on the lower edge of the cabinet and into the mounting surface, and tighten it into place.

8. Place the individual telephone stations as desired and in keeping with accepted industry and office standards. You can wall mount a telephone station if necessary (see Section 2.5.7 for details).

2.3 Making The AC Power Connection

You must employ a dedicated 117VAC 15 AMP circuit, with a third-wire ground, supplied to a standard electrical outlet (NEMA 5-15R) for the AC power connection.

For added equipment protection, connect a plug-in power line surge protector between the

•

power cord and the AC outlet. Thoroughly check out the installation before connecting the power cord to an electrical

•

outlet to apply AC power to the system.

2.3.1 Identifying The Fuses

The system is protected against short circuit damage by a fuse located on the right side of the common equipment cabinet. Always replace the fuse with one of the same value and type; otherwise, equipment damage could result.

Digital Telephone System IMI66–107

2.3.2 Grounding The System

If spare conductors exist in the cables between the station and the 66M-xx connector blocks, it is good practice to connect them to an earth ground. Doing this may help prevent them from inducing radio frequency and/or AC interference into the system. It is also good practice to disconnect any unused station jacks from the connector block and ground that wiring to an earth ground as well.

Transient voltage spikes, if induced onto CO or CENTREX lines, can travel through the cable and into the common equipment. The telephone company offers basic protection against this condition but it is usually designed to protect the central office circuits. While it will also provide some protection to the common equipment, you should not rely upon it for total protection. To help ensure that external over-voltage surges do not damage the system, you should install and properly ground primary protection devices, such as gas discharge tubes or similar devices, on all lines. While the line boards have internal secondary surge protection on all line ports, in order for this protection to be effective, you MUST connect the common equipment cabinet to a reliable, effective earth ground.

Proper DSU grounding is necessary for trouble-free operation and personnel safety. The DSU has the following three types of grounds:

Service Ground—a neutral power line wire that is connected to the ground bus in the

•

premises’ AC power panel, System Ground—a non-current carrying power line wire that is connected to the ground bus

•

in the premises’ AC power panel, Frame Ground—a low impedance conductor that places the common equipment cabinet at

•

reference ground potential. The frame ground provides the greatest safety by limiting electrical potential between non-current carrying parts of the system. The common equipment cabinet provides a ground stud on its cabinet for access to its frame ground.

Effective grounding requires that you connect the frame ground to a good earth ground. A good earth ground is one such as the ground bus in the premises’ AC power panel or a public metallic cold water pipe at a point immediately at its entrance to the premises and ahead of any meters, pumps, or insulating sections that have been added for vibration reduction. Avoid using the premises’ structural steel frame as it may not be at earth ground potential. Make the ground connection with #10 or #12 insulated, solid copper grounding wire. Keep the ground wire

separate from the three-wire AC line cord ground, do not splice it, and keep it as short as possible.

The impedance of the wiring between the common equipment cabinet and the earth ground must not exceed 0.25 ohms and the impedance between the earth ground and the power company’s reference standard ground must not exceed 4 ohms. Use an acceptable low impedance measuring device to measure the impedance of these paths. The #10 or #12 wire size will minimize the wiring impedance; however, if the impedance between earth ground and the power company’s standard reference ground exceeds 5 ohms, contact the local power company. The ground path must always be of sufficient current-carrying capacity to prevent a build up of voltages that may result in circuit noise, hazard to personnel, or equipment damage.

2 – 10 Installing The DSU

IMI66–107 Digital Telephone System

Be sure that all of the ground connections are without splices and are visible for inspection and maintenance. Tag all of the ground connections with a sign that reads: Do Not Remove Or Disconnect.

If you install expansion modules on the base cabinet, attach at least a #10 or #12 insulated, solid copper wire between the frame ground stud on the expansion module(s) to the frame ground stud on the base cabinet.

Remember, if spare conductors exist in the cables that run between the stations and the 66M-xx connector blocks, it is good practice to connect them to earth ground. Doing this may help prevent them from introducing radio frequency and/or AC interference into the system. Also remember that it is good practice to disconnect any unused station jacks from the connector block and ground that wiring to earth ground as well.

2.4 Connecting The Lines

The line terminations for the common equipment cabinet are standard modular plug/jack connections. Line configuration must be loopstart only. Each modular jack provides termination for two lines. Modular line jacks 1 and 2 also provide termination for an auxiliary pair in addition to the two outside lines. The outside line termination can be a type 66M-xx connector block or individual 6-position modular jacks. The line cord that is routed between the outside line termination and the common equipment termination should be twisted-pair wiring. The G0408, G0816 and G1632 common equipment supports the installation of up to 4, 8, or 16 lines, respectively. Add-on expansion modules are available to expand the line capacity of the systems.

2.4.1 Line Connection Details

The table on the next page shows the line connection details for all three of the common equipment base units. Jacks one and two are the same for all three cabinets, jacks three and four are the same for both the G0816 and G1632 cabinets, and jacks five through eight are only available on the G1632 cabinet.

2.4.2 Reassigning The Line Ports

After you have initially connected a line to a particular line port and programmed its attributes (or left it with the system defaulted values), you can reassign the line and its attributes to a different port by programming action if you wish. This feature allows you to make adds, moves, and changes without relocating the line wiring. Refer to Chapter 3 for the line to line port reassignment programming details.

2.4.3 Protecting The Lines

Transient voltage spikes, if induced onto CO or CENTREX lines, can travel through the cable and into the common equipment. The telephone company offers basic protection against this condition but it is usually designed to protect the central office circuits. While it will also provide some protection to the common equipment, it should not be relied upon for total protection. To help ensure that external over-voltage surges do not damage the system, the manufacturer recommends that gas discharge tubes, or similar primary protection devices, be installed and properly grounded on all lines (a selection of solid-state protection devices that are useful for this purpose is available from ITW Linx, Elk Grove Village, Illinois 60007).

2.5 Connecting The Stations

The digital telephone system supports the operation of proprietary Comdial telephones.

The G0408, G0816 and G1632 common equipment supports the installation of up to eight, 16, or 32 telephones, respectively. Add-on expansion modules are available to expand the station capacity of the systems. One 4-line 8-station expansion module can be added to the G0408. The G0816 and G1632 can each take two expansion modules.

Connections between the common equipment and the stations are typically via type 66M-xx connector blocks which are cable connected to the common equipment’s 50–pin male connector. The connector block is, in turn, wired to modular jacks that accept the modular line cord connected between it and the telephones.

The maximum distance allowed from the common equipment to the stations is per the following list:

Multiline Telephones—1000 feet using #24 gauge, twisted-pair cable or 2000 feet using

•

#22 gauge cable

When installing the system telephones keep in mind that each station port supports only one proprietary telephone and the system does not allow you to bridge two stations to a single modular jack.

Always route station wiring a minimum of 12 inches from any other parallel wires or electrical devices. If electrical noise or RF energy is at a high level, this may require the use of shielded cable with the shield connected to the cabinet ground lug.

2 – 16 Installing The DSU

IMI66–107 Digital Telephone System

2.5.1 Grounding The Stations

Remove insulation and twist together all spare wires at the wall outlet. Ground the wires at the 66M-xx to the common equipment cabinet ground lug.

2.5.2 Relocating The Stations

The Comdial proprietary telephones identify themselves to the system when you install them. The system assigns an extension number and all other programmable attributes to station ports as a default that you can reprogram as needed. Plus, you can use programming action to reassign attributes of one station port to a different station port if you wish. This station relocation feature allows you to do adds, moves, and changes without relocating the station wiring. Refer to the automatic station relocation programming procedure and the station-to-station programming procedure found in Chapter 3.

NOTE: The system will not allow you to relocate the station 10 to station port 10 assignment.

2.5.3 Installing The Cable Clips

Each cabinet-mounted 50-pin male connector is equipped with a retaining clip. This clip is designed to secure the mated connection once it is made. The clip does this by snapping into a slot on the cable-mounted connector when it is pressed together with the cabinet-mounted connector. This retaining clip must be pulled back slightly to unsnap it before the connectors can be separated.

To wall-mount the telephones,

After configuring a telephone for wall mounting, either mount it directly on the wall using two #10 panhead screws (obtained locally), or mount it on a wall jack cover plate. If using a wall jack cover plate, use an AT&T type 630B wall plate for best results.

1. If #10 screws are used, thread them into the wall within 1/8-inch of the surface. Refer to Figure 2–9 for the spacing dimensions.

2. Position the keyhole-shaped holes in the bottom of the telephone over the #10 screws or the cover plate studs. Slide the telephone down until a slight click is felt.

3. To remove the telephone, lift to unsnap both screws or studs from the bottom housing, and then lift away from the wall.

2.6 Installing DSS/BLF Consoles

The digital telephone system supports the installation and use of a DigiTech DD32X or Impact IB64X consoles at any available station port. The number of installed consoles is limited only by port availability; however, since a console complements a companion telephone located in an adjacent station port, you can use up to one-half of the available station ports for consoles. In addition, with the dual console feature (discussed later), a full two-thirds of the total station port capacity is available for console use.

You can assign two consoles to one telephone, each taking its own station port. This feature is especially useful with DigiTech DD32X consoles and a G1632 system that has one or two GM408 expansion modules included with it. This dual console feature allows a station user to monitor up to 48 stations from one station location using 32-button consoles.

Install the first console at the station port that is logic-paired with the station that you wish to complement. Install the second console at any station port except 10 or 11 and, using class of service programming, assign it to the same station port that is logic-paired with the first console.

Table 2–7: Pairing Of Digital Station Ports

10–11 26–27 42–43 12–13 28–29 44–45 14–15 30–31 46–47 16–17 32–33 48–49 18–19 34–35 50–51 20–21 36–37 52–53 22–23 38–39 54–55 24–25 40–41 56–57

You can install the DSS/BLF console at any station port and assign it to a station without first installing a console at the station’s logic-paired port if you wish. This configuration is convenient for adding a console to an existing telephone installation that already has its logic-paired port occupied; however, do not use this configuration for assigning a console to station ports 10 and 12 because the console buttons will not be usable for programming. As discussed above, this feature is also useful for adding a second console to a station that already has a paired console installed with it.

The digital telephone system automatically recognizes a console when you connect it to a station port and automatically assigns the station intercom numbers to the console buttons for direct station selection (DSS) purposes with associated busy lamp field (BLF) status lights. However, the console buttons are fully programmable and the station user can customize them as he or she sees fit by programming them as DSS buttons or as automatic dialing (autodial) buttons. When the user programs the buttons for DSS use, autodial capability is also available at a secondary level at each DSS button.

2 – 26 Installing The DSU

IMI66–107 Digital Telephone System

While the first console (the one installed at the logic-paired port) extends the autodial buttons of the paired telephone by 48 and provides DSS/BLF coverage for station ports 10 through 57, the second console (the one installed at the programmed station port) provides DSS/BLF coverage as follows:

On a 32-station system with two 8-station expansion modules, the first 16 buttons are

•

automatically assigned (defaulted) to station ports 42 through 57 for DSS purposes. On a 32-station system with one 8-station expansion module, the first 8 buttons are

•

automatically assigned (defaulted) to station ports 42 through 49 for DSS purposes. On any other smaller station capacity system, all buttons are unassigned.

•

When you install a console and program it to complement a telephone without first having a console installed at a port that is logic-paired to that telephone, its button assignment is automatically defaulted, as described above, but the user can reprogram it as required. It is important to remember that when you program for a second console, the system sets the console button mapping to that which is described above. When you clear the assignment, the system resets the button mapping to match a logic-paired console. This means that when you clear the second console feature, the console installed at that port complements the telephone that is installed at its logic-paired port instead of the telephone that is located at the program-designated port, and its buttons are automatically reassigned to station ports 10 through 57.

2.7 Connecting A Power Failure Station

The system provides a tip and ring pair connected to line 1 as an emergency power failure circuit. This circuit is active during a commercial AC power failure if an external battery assembly is not installed to provide battery back-up power to the system. Connect an industry standard, single-line telephone, such as a model 2500, to a power failure pair and use it to provide communications capability until the AC power to the system is restored.

NOTE: The system also provides one power failure connection with each add-on expansion

module.

2.8 Using The Auxiliary Equipment Interface

You can connect an industry-standard telephone or a data device such as a modem or a FAX machine on a line ahead of the common equipment if you wish. If you do so, the system can detect an off-hook condition in the connected device and turn on the line status light at the system telephones to indicate that the line is busy.

Connection is across tip and ring of lines 2 and 4. The system provides the auxiliary interface connections at terminals 1 and 6 of common equipment line jacks 1 and 2.

NOTE: When you are employing this auxiliary interface feature, the line-to-line port

reassignment feature (Section 2.4.2 ) works as described except in regard to line 2 and line 4. You can only reassign Line 2 to line port 4 and line 4 to line port 2.

2.9 Common Audible And Auxiliary Ringing Interface

You can use the relay closure dry-contact points for controlling external audible equipment. These contact closures track the pattern of the ringing for incoming calls. The contacts are closed during the ringing period and are open during the silent period.

CAUTION

Do not exceed a 1 amp at 24 volts (0.5 amp at 48 volts) load on these control terminals. If the load requirements exceed this limit, connect the load through an external slave relay. DO NOT CONNECT THESE CONTROL TERMINALS DIRECTLY TO THE 117VAC LINE.

2.9.1 Connecting Outside Lines

Common audible terminals provide a dry-contact closure whenever any of the outside lines that you have connected to the common equipment ring with an incoming call.

2.9.2 Connecting Selected Ports

Station 17 audible terminals provide a dry-contact relay closure whenever ringing is sent to station 17 or to a programmable destination. Use class of service programming to choose either the station 17 or the programmable paging port as the ringing destination. Refer to Chapter 3 for programming details.

When you have programmed for station port 17 ringing, it is a common practice to use a customer-supplied external device to provide loud ringing and connected in a manner similar to the common audible arrangement shown in the illustration on the next page.

CAUTION

Do not connect an external paging device or any external ringing device to station port 17 connections.

When you have programmed for paging port ringing, it is a common practice to use a customer-supplied external paging amplifier connected to the paging port to amplify and broadcast the ringing tones sent to the paging port by the system. You can employ the relay closures that appear at the ringing terminals to energize the external paging amplifier during the periods when the ringing tones are being sent if necessary.

NOTE: Refer to Section 2.10 for a discussion of external paging amplifier connections and

information for using the paging port ringing terminals in an alternate paging enable function.

2.10 Using The External Paging Interface

The system provides a special transformer-isolated paging port that you can use to couple the system to a customer-supplied external paging amplifier. This external paging port does not provide a talk-back path nor will it recognize DTMF dial tones.

You can use the relay closure dry-contact points that the system makes available at the ringing port terminal for controlling the external paging amplifier during a paging operation. These contacts close and stay closed during the time that a paging operation is active to provide a constant enable signal path for the paging amplifier.

NOTE: This paging enable constant closure function overrides the ring pattern closure

provided when ringing is sent to the paging port.

Connect the audio input of a customer-supplied external paging amplifier to the paging port.

2.11 Using A Line Port As An External Paging Interface

You can use class of service programming to program a line port to be an AUXILIARY port. As an AUXILIARY port, a user can use it to couple a telephone to an external paging device that you have wired to the line port. He or she does this from any station with that line presence by pressing the proper line button to select the AUXILIARY port. The user can dial DTMF tones or dial pulses through the AUXILIARY port as needed. The paging enable relay closure feature discussed previously is not available for use with this installation.

Connect the audio input of a customer-supplied external paging amplifier to the tip and ring

•

leads of the AUXILIARY port. You can install a DTMF tone select, zone-paging amplifier if you wish. If you do install

•

this type of amplifier, the user must dial the zone-select code after he or she presses the AUXILIARY port line select button.

2.12 Connecting Data Devices

This section contains information on two stages of wiring connections for data devices.

Section 2.12.1 explains connections from stations to modular jacks. Section 2.12.2 details wiring from the modular jack to the DSU by way of the punch-down-block.

2.12.1 Making Modular Jack Data Connections

Modular jack connections are wiring connections from a station to a modular (wall) jack.

The system provides two RS232 Data Ports for use.

When you use a video display terminal (VDT) to perform class of service programming,

•

connect it to RS232 Data Port A. When you use a serial data printer for SMDR, SMDA, COS printout, or Caller ID, connect

•

it to the RS232 Data Port B.

NOTE: The distance between a data device and the common equipment can be up to 500 feet

in a quiet electrical environment. Some sites may require shielded cable for long runs. For longer distances, you must install limited distance modems to relay the data communications between the common equipment and a data device.

When preparing a cable for connection to a data device, refer to the manufacturer’s manual for the equipment being interfaced and make the following wiring connections:

Wire the common equipment RD (data from device to common equipment) connection to

•

the device TD (transmit data) connection. Wire the common equipment TD (data to device from common equipment) connection to

•

the device RD (receive data) connection. Wire the common equipment SG (signal ground) connection to the device SG (signal

•

ground) connection. If required for proper operation, wire the common equipment CTS (clear-to-send status

•

from device to common equipment) connection to the device RTS (request-to-send) connection.

NOTE: The common equipment requires a positive voltage, with respect to signal ground, in

order to send data.

2.12.2 Making The Common Equipment Data Connections

You must make wiring connections from the modular jack (wall jack) to the G0408 and G0816 common equipment cabinets by way of the punch-down-block, while the G1632 cabinet provides modular jacks for the data connections.

The default data communications format is as follows:

7-bit data with 2 stop bits and no parity

•

Baud rate of 300 baud.

•

Configure a data device to match this format for initial operation or reprogram the system’s data format to match those of a data device. The tables below list the system’s data ports.

NOTE: The distance between a data device and the common equipment can be up to 500 feet

For G0408 and G0816 cabinets, make data connections at the station connector block as follows: Clip terminals 37-40 (data port A) and clip terminals 41-44 (data port B).

2.12.3 Programming With A Video Display Terminal

You can program the digital telephone system using a telephone or a Video Display Terminal (VDT). You can connect the VDT directly to the DSU, or you can program the system remotely using the following equipment:

VDT or a PC and appropriate software program,

•

Pair of data modems.

•

The data modems must be: “Hayes-compatible,” capable of 300-, 1200-, 2400-, or 9600-baud data speeds, and have auto-answer capability. Be sure to verify the auto-answer capability before purchasing the units. You are assured of best results if you employ modems of the same make and model at both the installation site and the remote programming site.

The equipment connections for the customer location are shown in Figure.

1. Determine the signal needs of the modem from the user’s manual for it. (The digital telephone system only requires TD, RD, and SG but the modems may require more signals. Check with the modem manufacturer for special requirements).

2. Wire the proper connector (to match the data jack) on one end of a length of multiline cable.

3. Punch down the appropriate leads on the connector block.

4. Connect the network jack of the data modem to an outside telephone line. (If a line is not reserved for remote programming, have a line switch installed so that on site personnel can switch the outside telephone line between the data modem and the digital telephone system cabinet when you are going to perform remote programming.)

5. Refer to the user’s manual for the modem, and program the modem to automatically answer after the first ring.

6. Interface the VDT or PC with the modem at the programming site per the user’s manuals for the equipment be used.

7. Establish a communications link for programming the system from a remote site.

If you have had a line switch installed at the customer site, call someone there and ask them

•

to set it for modem operation. After the outside line is connected to the modem, make the data link between the

•

originating and the remote modems, and perform programming from your remote site just as if the VDT or PC was connected directly to the system.

2 – 38 Installing The DSU

IMI66–107 Digital Telephone System

If you experience difficulty in establishing a communications path between your VDT, modems, and the digital telephone system, note the following suggestions:

make sure that you have enabled the modem auto-answer feature,

•

confirm that the modems are wired correctly. Reverse connections at pins 2 and 3 if

•

necessary, check the modem’s instruction manual. You may have to make additional wiring

•

connections, sometimes you must strap pin 4 to 5, or pin 6 to 7, or pin 6 to 8 to 20 in the modem wiring.

•

Check the modem’s installation manual for this requirement, use a breakout box data tester to troubleshoot the data communications lines.

2.14 Using The Add-On Expansion Module

You can install one or two optional add-on expansion modules on the common equipment base unit to increase the line and station capacity of an installed system.

The default numbering of the expanded lines and stations begin with the next higher line or station port number from that provided by the host base unit. The numbering continues sequentially from top module to bottom module if two modules are installed. For example: The defaulted 8-line, 16-station base unit provides station ports 10 through 25 and lines 1 through 8. When installed, a 408 Expansion module will provide station ports 26 through 33 and lines 9 through 12 thus creating a 12 line by 24 station system.

Each expansion module provides a tip and ring pair as an emergency power failure circuit. This circuit is connected to the first module-provided line.

The line connections of the expansion module are available at two modular jacks. When facing the jack openings, lines 1 and 2 are provided by the jack on the right and lines 3 and 4 are provided by the jack on the left.

Digital Telephone System IMI66–107

Connecting The Battery Back Up Assembly

The common equipment provides an interface connector for the connection of an optional external battery assembly.

CAUTION

Be sure that the AC power cord is connected to the electrical outlet before connecting an external battery assembly to the common equipment interface connector. This ensures that internal protection circuitry is operating to prevent damage that could result from improper connection.

The external battery assembly provides a minimum of one hour of operation should the AC power to the system be interrupted. The assembly has a 15 ampere-hour current rating and is fused with the following vaue: 4A 250V 3AG type.

The external battery assembly may include batteries from either of the following suppliers:

Model PS-12150 from Power-Sonic Corporation, Redwood City CA, 94032

•

Model PE12V15 from GS PORTALAC, City Of Industry CA, 91748

•

The minimum battery backup time for a fully configured system can be calculated using the formula:

Back Up Time (in hours) =

K(15)

1 + [(0.1) (N)]

K (Constant) = 0.9 for G0408 with or without a GM408 module

0.8 for G0816 with or without GM408 modules

0.8 for G1632 with or without GM408 modules

15 = ampere-hours N = total number of stations

Example: Assume that a G1632 system plus two GM408 modules are installed along with the optional battery assembly to provide back-up power.

Back up time =

(0.8) (15)

1+[(0.1) (48)] 5.8

= 2.1 Hours

2 – 56 Installing The DSU

IMI66–107 Digital Telephone System

During AC operation, the common equipment provides recharging current to maintain the voltage potential of the external battery assembly at an operational level. The charging circuit may not provide an adequate charge if an installed battery assembly has a current rating of greater than 40 ampere-hours. You should measure the battery assembly voltage every three months.

For proper backup capabilities, make sure the batteries meet the following specifications:

With a fully-charged battery assembly disconnected from the common equipment, the

•

measured voltage must be greater than 12 VDC but should not exceed 13.5 VDC. With a fully-charged battery assembly connected to the common equipment, the measured

•

voltage should be less than 13.8 VDC. If the voltage measures higher than this limit, contact your Comdial Technical Services representative.

The open output of the common equipment battery charger connection measures 13.6–13.8

•

VDC. If the charging voltage measures higher or lower than this range, contact you Comdial Technical Services representative

An optional external battery assembly requires approximately 10 hours to completely

•

re-charge to full potential after it has been completely discharged and, in some cases, when initially installed.

2.18.2 Installing The Analog Terminal Interface

Introducing The Analog Terminal Interface

The ATI-D is a multipurpose, on-premise accessory for the digital telephone system. It has dual circuits that provide the following features:

INDUSTRY-STANDARD TELEPHONE (IST) INTERFACE—This feature adapts most

•

industry-standard telephone (IST) devices to the digital telephone system. The ATI-D will accept both tone (DTMF) and pulse (rotary) dialing from these devices.

SYSTEM INTERCONNECTION—This feature allows an installer to connect two digital

•

telephone systems to each other using two ATI-Ds and on-premise wiring. When interconnected, either telephone system treats the other telephone system as an IST device. The two telephone systems are not integrated together and do not share features.

MODEM ADAPTER—This feature allows the flow of switched data between a data source

•

and a data receiver through the digital telephone system. VOICE MAIL/ANSWERING MACHINE INTERFACE—This feature allows an installer

•

to connect voice mail systems and automated answering devices to the digital telephone system.

CAUTION

The ATI-D by itself does not support any off-premise service. Never connect the ATI-D to a telephone company-supplied line unless you have first installed an acceptable OPX long loop adapter.

The ATI-D is housed in a self-contained metal enclosure that can be wall mounted if desired. The ATI-D is powered by the digital telephone system through the station port connections and employs an internal ringing generator to generate a ringing signal for an IST. Dual, high-quality, low-loss, balanced, telephone transmission circuitry supports two IST inputs.

One 2-pair cable (four-wire) connects the ATI-D to two common equipment station ports. A single pair of wires connects the external analog IST equipment to the ATI-D. Modular connectors are provided to allow quick connections.

Each ATI-D circuit drives a load with a maximum ringer equivalence number (REN) of 2.0, thus allowing more than one IST connection at each interface input. Check the REN number of the connected IST equipment so as not to exceed the capacity of the ATI-D. Improper operation may result if the REN maximum of the ATI-D is exceeded.

The ATI-D supports a wide variety of IST equipment such as 500 and 2500-type telephones, cordless telephones, voice mail systems, answering machines, FAX machines, and data modems.

IMI66–107 Digital Telephone System

Figure 2–28: Detailing The ATI-D Dimensions

Installing The DSU 2 – 61

Digital Telephone System IMI66–107

Connecting The Analog Terminal Interface

Connect the ATI-D per the diagram detailed on the following page. A grounding wire is not required for operation; however, one is desirable for decreasing radio frequency interference and electrostatic discharge susceptibility. The ATI-D housing provides a frame ground stud for this purpose. Connect a #10 or #12, insulated, solid copper wire between this ground stud and a reliable earth ground.

NOTE: You must connect both station ports to the ATI-D, even if you plan to use only one

IST device. Connect the first ATI-D port to an even station port. All ATI-D ports must be paired.

CAUTION

Be careful when connecting the wiring between the common equipment and the ATI-D. Be sure to connect the common equipment station ports to the COMMON EQUIPMENT (KSU) jack on the ATI-D. Damage to the ATI-D could occur if this wiring is mistakenly connected to the IST jack.

Use a voltmeter to check for the presence of voltage on the ATI-D IST jack.

1. Be sure that you have installed all the wiring between the ATI-D and the common equipment station ports.

2. Measure for DC voltage on IST jack: —Measure between TIP leads and common equipment grounding stud. —Measure between RING leads and common equipment grounding stud. —Measure between TIP leads and RING leads. The measured voltage must be within following limits: MEASUREMENT VOLTAGE Tip to Ground +3 to +11 VDC Ring to Ground -13 to -21 VDC Tip to Ring +23 to +25 VDC (The TIP lead is positive with respect to the RING lead.)

Installing A Voice Mail Interface

You can use the ATI-D to provide interfacing for a customer-supplied voice processing system. The ATI-D, using paired station ports (such as 12 and 13 or 14 and 15), will support two voice mail ports.

To complete the installation, connect the voice mail ports to the IST jacks on the ATI-D.

Installing An OPX Long Loop Adapter For Off-Premise Service

As stated previously, the analog terminal interface is an on-premise device. You must use an OPX long loop adapter if you wish to adapt the ATI-D to support an off-premise application. An OPX long loop adapter connects to a single telephone line and can greatly extend the line’s loop length (the Proctor Model 46222 adapter*, for example, can extend line length to 30,000 feet).

*Proctor & Associates Company, Redmond WA

CAUTION

When you connect an adapter to an off-premise extension (OPX), you must install primary protectors in series with the tip/ring pair of the telephone line that is routed to the OPX. This action is necessary to protect both the user and the equipment from transient voltage spikes that can travel through the cable. The telephone company offers basic protection against this condition; however, that protection is usually designed to safeguard the central office circuits and you cannot rely upon it to protect common equipment. To help insure that external overvoltage surges do not damage the system, installation specialists recommend that you install and properly ground gas discharge tubes or similar primary protection devices on the telephone line that routes between the adapter and the OPX.

To install the OPX long loop adapter:

Follow manufacturer’s instructions for unpacking, inspecting, mounting and wiring the

•

adapter unit. Plug a modular cable into the system jack on the adapter and connect the opposite end of

•

the cable to the IST jack on the ATI-D. Plug a modular cord into the telephone jack on the adapter and connect the opposite end of

•

the cord to the OPX line (see Figure 4). Plug the adapter power cord into a standard 117 VAC, 3-wire electrical outlet.

Understanding The Programming Requirements

The ATI-D provides the interfacing capability required to connect most IST equipment to a station port of an digital telephone system.

The IST provides basic intercom service coupled with the ability to access outside lines. Through programming, the IST acts as either as an intercom-only telephone or as a full-featured business telephone. You can program the station port through which the IST is being interfaced either for prime intercom or for prime line automatic and idle line preference. Default is for prime intercom. You can also program the station port for outside line ringing and to match the type of dialing method employed by the IST.

Prime Intercom

On key configured systems, telephone users can extend line access to the IST for call origination through the use of the call transfer feature. Through programming, you can assign outside line ringing to the IST even though it is programmed for prime intercom access. To do this, program the station port for the ringing line preference feature and enable ringing for all desired lines.

On hybrid configured systems, the system gives the IST access to outside lines through line group access. With line group access, IST users dial the group access code over the intercom line to access an outside line for use. The common equipment then selects one of the grouped idle lines for use in the order from the highest numbered line to the lowest numbered line.

Prime Line Automatic Or Idle Line Preference

Program an outside line as a prime line at the station port through which the IST is being interfaced, or program the station port for idle line preference and then program one of the assigned idle lines as a prime line.

With both prime line automatic and idle line preference features, the IST has outside line dial tone when the user lifts the handset. Through programming, you can assign outside line ringing to the IST station port that you have programmed for prime line automatic or for idle line preference. Alternately, you can enable the ringing line preference feature for the station port.

The intercom line is available to an IST even though you have arranged it to have outside line access. After going off-hook, the IST user obtains intercom dial tone by performing a hookflash. To perform a hookflash, he or she must press and release the hookswitch. This action either drops the outside line (if no digits are dialed after lifting the handset) or places it on hold (if digits were dialed) and provides intercom dial tone.

ATI-D Distinctive Ringing

Intercom calls that ring at equipment connected through an ATI-D have a different cadence than outside calls. Intercom ring cadence is: 1 sec. on, .5 sec. off, 1 sec. on, 3.5 sec. off. Outside call ring cadence is: 2 sec. on, 4 sec. off. You can program disable this distinctive ringing feature to make the intercom ring cadence the same as that for outside calls.

Through Dialing

You can program the station port that interfaces the IST for through-dialing if you wish or you can disable this feature. The system automatically enables this feature when you connect the ATI-D to the station port. If the IST is a dual-tone multi-frequency (DTMF) tone dial device, dialing tones generated by it pass through the ATI-D, the common equipment and onto a tone dial compatible telephone line. In this case, the station port must have through-dialing enabled. However, if you use a rotary telephone as an IST device, you must disable through-dialing.

2.18.3 Installing The Data Interface Unit

Unpack the Data Interface Unit (DIU) and check for the following parts:

Telephone line cord

•

Power cable with attached transformer.

•

Verify that the Digital Service Unit (DSU) contains software revision 17A or later. If you need to upgrade the DSU software, see the section entitled “Software Cartridge.”

Installing The Mechanical Components

You can install the DIU in either a free-standing manner or you can mount it on a wall.

When mounting the DIU on a wall:

1. Select a location that is close to a standard 115 VAC electrical wall outlet. The location you select should also be convenient to the digital telephone and the Industry Standard Telephone (IST), FAX, or modem—whichever one you will be connecting to the DIU.

2. Once you have selected the location for mounting the DIU, mark two locations for the mounting screws as follows:

a. make the first mark, b. measure 3 13/16 inches horizontally from the first mark and make the second mark.

3. Install two #8 X 3/4-inch screws in the wall at the locations you marked in step 2. Tighten the screws until the screw heads are 1/4-inch from the surface of the wall.

4. Place the DIU on the wall with the screw heads inserted into the slots provided on the bottom surface of the DIU. Slide the DIU onto the screw heads until it is firmly attached to the screws.

Making The Cable Connections

Four cable connections are required to the DIU—station line cord, digital telephone line cord, IST/FAX/MODEM line cord, and power cable.

1. Disconnect the line cord on the digital telephone from the digital station port connector and plug it into the connector labeled PHONE on the DIU.

2. Plug the line cord from the IST device you are installing with the DIU (such as a FAX machine, or modem) into the DIU connector labeled FAX/MODEM.

3. Plug the transformer attached to one end of the power cable into a 115 VAC electrical wall outlet. Connect the other end of the power cable into the DIU connector labeled POWER. The green LED on the DIU will be on to indicate power is being supplied to the DIU.

4. Plug one end of a standard line cord into the connector labeled LINE on the DIU. Plug the other end of the line cord into the digital station port connector.

NOTE: DIU power loss will create the same symptoms as the disconnection of the DIU from

the digital telephone system. If this occurs, plug the multiline digital telephone directly into a digital station port connector.

Preparing The DSU For DIU Operation

Once you have verified that the system contains the correct software, you must program the system for DIU operation. See Chapter 4, “System Programming” for programming details.
