MOUNTING CONSIDERATIONS

The KSU cabinet should be attached vertically to

any sturdy, flat, surface. It may be vertically rack mounted if desired.

The KSU must be located within six (6) feet of a

proper electricaloutlet. The KSU power supply requires a dedicated 117VAC 15 AMP circuit, with a

third-wire ground, supplied to a standard (NEMA

electrical outlet.

The distance between the KSU and the

as per FCC requirements. A nominal distance of 7 feet is recommended.

The mounting location must be secure and dry and have adequate ventilation. The temperature range of the location must be within 32-l 22 degrees F

(O-50

degrees C).

If the mounting surface is damp or if it is concrete or masonry material, a backboard must be attached to

the mounting surface to be used for KSU mounting.

Suitable mounting backboards are available commercially or can be constructed out of plywood cut to size.

Tools and hardware required for mounting the KSU cabinet include:

SECURE OFF-HOOK VOICE ANNOUNCE

TELEPHONE CONNECTIONS This telephone system supports the Secure Off-Hook

Voice Announce (SOHVA) feature provided by certain required to provide the SOHVA feature.

NOTE:

non-secure off-hook voice announce capability is required, it can be provided by the model DB32S-xu console as described above.

The SOHVA equipped telephones contain a

line jack. Using

twisted-pair

cable, connect the two inside pairs of the line jack to the first data-paired port and connect the outside pair to the second data-paired port. Refer to Flgure 2-5 for

an illustration of this wiring.

Connect pins 3 and 4 to the voice pair and pins 2

and 5 to data pair of the first data-paired port.

Connect pins 1 and 6 to the voice pair of the second

data-paired port.

To enable the SOHVA feature, the following

programming considerations must be taken:

The first paired-port must be programmed as a

port.

The second paired-port must be programmed as a

DSS console with call announce port.

POWER FAILURE STATION CONNECTIONS The system provides three tip and ring pairs

connected to lines

and 3 as emergency, power

failure circuits. These power failure pairs are located

as detailed on Table 24 and Figure 24. A power failure pair is only active during a power failure. An

industry standard, single-line telephone, such as a

type 2500, can be connected to a power failure pair

and used to provide communications capability should the AC power to the system be interrupted.

A-LEAD CONTROL

DEVICE CONNECTIONS

The KSU can detect an A-lead (A and Al) control signal when it is applied to lines 7 and 8. An A-lead control device can be bridge-connected to these lines via terminal clips on the J-4 station connector block. Refer to Table 24 and Figure 24 for connection

details.

DATA DEVICE CONNECTlONS

When a serial data printer is used printout, or a video display terminal (VDT) is used to perform class of

programming connect the data device to terminal clips on the J-4 station connector block.

The distance between the device and the KSU can be up to 500 feet in a quiet electrical enviroment. Shielded cable may be required at some sites for runs. For longer distances, a limited distance modem must be used to relay the data communications between the wmmon equipment and the data device. Refer to Table 2-4 for connection details.

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

Wire the KSU RD line (data from device to KSU) to

the device TD (transmit data) output pin.

If station port 41 is programmed as a PA port, the Auxiliary Station Interface (station port 17 audible) contact points are automatically reconfigured as PA enable terminals. The contact closure now occurs when PA station port 41 is dialed. The normal auxiliary station interface function, as discussed previously, is disabled as long as station port 41 is a PA station.

COMMON AUDIBLE AND

AUXILIARY STATION INTERFACE

Two sets of relay closure available at the J-l bbcks.One set (J-l connections) provides a dry-contact closure whenever any of the TELCOIPBX

lines, connected to the KSU, ring. The other set (J-2 connections) provides a dry-contact closure whenever system station port 17 rings. These contact closures

track the ringing pattern in both cases. The contacts

are closed during the ringing period and are open during the silent period.

Programming overlays are included with each system for use in identifing the buttons required for COS programming. One overlay fits over the buttons of the station installed at station 11 and designates the A-field and B-field buttons.

The other overlay fits over the buttons of the console Installed at adjunct port 10 or 11 and designates the C-field buttons. Full size copies of the programming overlays are included at the end of this chapter for use if needed.

System and line COS programming do not require that a sequential process be followed once the base

Prior to taking any programming action, determine the system, line and station COS conditions and all toll restriction requirements. Record this data on the programming reference tables included within the programming procedures.

A set of COS values can be recorded on cassette tape from a programmed system and later re-loaded into the same system or into another system. This method of programming can be employed in lieu of using the step-by-step programming sequence.

A complete or a partial printed record of the COS program values can be obtained with a serial data printer connected to the

KSU. Complete details concerning this procedure are included at the end of this chapter.

TOLL RESTRICTION PROGRAMMING

In order for toll restriction to take effect, the following

three-fold process must occur:

One or more toll tables must be entered. Toll tables must be assigned to all appropriate lines. Toll tables must be assigned to all appropriate stations

Only the toll table(s) which are entered and assigned to both a line and a station using that line will involk

any toll restriction. Toll tables 1 and 2 have entries defauted in them and these tables are assigned to all

lines by default. These tables are not assigned to

stations by default.

TABLE ENTRY PROCEDURE

Determine the types of dialing restrictions which

be imposed on the system. Typically, this includes access codes which result in toll charges, and certain local numbers as desired.

If the restricted dialing codes will be imposed consistently on most or all stations in the system, list them on one or two tables. If wide variation in the dialing restrictions is planned, spread the listing out across several tables.

Strategically group the listings on the tables so that a list of restrictions can be applied to a particular station or group of stations.

Designate each table as a DENY table or as an ALLOW table. The numbers entered in a DENY table are prevented from being dialed. ALLOW tables take precedence over DENY tables. Therefore, an entry in an allow table will provide an explicit exception to an entry in a DENY table. Note that the system always permits the dialing of

any number not explicitly denied. Also, system speed dial numbers will not be toll restricted unless specified by station COS programming.

can be included in an entry in either a DENY table or an ALLOW table.

Example A: If 357, 377,387, and 397 dialing is

to be prohibited, list one entry of

on a

DENY table to cover them all.

Example B: Since all area codes typically have a 1 or a 0 as a middle digit, prevent bng distance calls to those area codes by entering

never be restricted, atways create an allow table with entries of 911 and 1911 to override any DENY tables that have been created.

If the system is installed behind a PBX, include an access code as part of every table entry.

Once these tables are completely filled out, enter the restriction planning tables on the line, and station programming reference charts to record the planned toll restrictions for the system.

A particular station can be linked at the end of more than one hunt group so long as the sixteen station ports per group are not exceeded. For instance, a second terminal hunt group could be formed along with the example shown above:

Station port 020 is linked to station port 021 Station port 021 is linked to station port 022 Station port 022 is linked to station port 016. Thus, station port 016 would serve in both terminal

hunt groups afthough the groups are independent

otherwise. Other terminal hunt groups could also be formed with station port 016 as the last station in the group.

CIRCULAR HUNTING

A hunt group can be made circular by linking the last port in the group with the first port in the group. From the first example given above, a circular hunt group could be formed as follows:

Station port 013 is linked

Station port 014 is linked to station port 015 Station port 015 is linked to station port 016

Station port 016 is linked to station port 013.

In a circular hunt group, a call will search around the

group until it encounters an idle station port or until all stations in the group, up to a maximum of sixteen, are searched.

TAPE RECORD OF COS VALUES

GENERAL INFORMATION

Connect the audio cassette tape recorder microphone connector to the music interface jack on

the side of the KSU.

Do not perform any other programming action while

the tape system is active.

Program the baud rate of the tape data to be either 100 or 50 baud as desired. (See System COS for programming details.)

if the system includes a data printer, appropriate response and error messages will be printed during the recording and loading of COS data.

When COS data is sent from the KSU to an audio cassette tape recorder for recording, a lead-in tone

is sent prior to the data. During play-back, this lead-in tone alerts the system to receive the class of service data.

When playing back the stored class of service data, the tape must be started during the lead-in tone.

service data. To insure a successful load, comparison, or

verification of recorded class of service data, always start the tape during the lead-in tone. The following precautions will insure that this is done.

Before playing back pre-recorded class of service

data, perform the following actions:

Rewind the tape to the beginning. Disconnect the cable connecting the recorder

KSU.

Set the play-back volume for approximately one-half of

maximum. Play the tape and listen to the lead-in tone. Verify that

is not distorted. Rewind the tap to the point where the lead-in tone

begins. Connect the cable between the KSU and the tape

FAILURE KSU AND STATION

Figure

details a failure analysis flow chart to assist a service technician in isolating a failure in a defective system. One way to isolate a failure is to substitute a known good assembly for a suspected one. This is

the recommended failure isolation method to use with the system. Connecting and disconnecting stations to the system does not affect the stored station auto/speed dial memory data. This data is stored in the KSU memory and not at the individual stations.

Replacing the KSU, however, causes all stored memory to be lost. This includes all memory dialing

numbers as well as all COS programming data.
