CHAPTER 2

INSTALLATION

MOUNTING CONSIDERATIONS

The KSU 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 electrical outlet. The power supply requires a dedicated 117VAC

wire ground, supplied to a standard (NEMA

.15

AMP circuit, with a third-

515R)

electrical outlet.

l The distance between the KSU and the

TELCO/PBX jacks must be 25 feet or less 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 32-122 degrees F

(O-

50 degrees C), and the relative humidity must be less than 90 percent non-condensing.

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

l/Binch

plywood cut to size.

Tools and hardware reauired for mountina include:

Fasteners - wood screws

(l/4

x 1

-in&

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

MOUNTING PROCEDURE

Unpack, and carefully inspect all equipment for shipping damage. Notify the shipper im-

mediately of any damages found. Verify that

the packages contain all parts and accessories

needed for proper installation and operation.

Afull

scale mounting template is supplied in the

packing box. Hold ortape it to the mounting sur-

face, and mark the location of the mounting

holes on the mounting surface as they are located on the template. The mounting dimensions are shown on Figure 2-l . .

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 dic-

tated by the type of mounting surface.

Attach the KSU to the mounting surface with

5. four (4) screws installed through the KSU

mounting flange and into the mounting surface holes. Note that the flange holes are elongated

with an enlargement at one end. This feature

allows the mounting screws to be partially installed in the mounting surface before the cabinets are hung on them.

Place the individual telephone stations as desired and in keeping with accepted industry and office standards. Currently produced 8

tine Keysets can be wall mounted if necessary as they are

desk/wall

reversible. Currently

produced keyset models include:

SYSTEM WIRING

System cabling may be routed concealed or visible as the installation location requires, Good engineering practices must be observed codes must be adhered to. through 2-4 illustrate the system wiring and connection points for the key system.

AC Power Connection

The AC power is applied to the system by connecting the AC power cord to the standard (NEMA

electrical outlet which supplies the dedicated 117VAC

@ 15 AMP electrical power.

The following precautions should be taken to help

prevent damage to the system which could be caused by an electrical over-voltage condition.

Line Connection

The KSU interface connections for the COlPBX lines are individual

connectors and the demarcation point connectors is via

standard modular line cord.

tip/ring loop resistance is 1900 ohms from the KSU

modular jack to the CO/PBX equipment.

To help Insure that foreign voltages, which could

appear on the CO lines, do not damage the system,

verify that gas discharge tubes orsimiiarprotection devices are installed, and properly grounded, in all connected CO lines.

Do not connect the ACpower cord until the installation has been checked per the SYSTEM

CHECKOUT instructions given at the end of

this Chapter.

Employ a dedicated lVL!AC 15 AMP circuit, with a third-wire ground, supplied to a stand-

ard (NEMA

5-15R)

electrical outlet for the

power connection.

Statlon Connection

Connections between the KSU and the stations are typically via type 66M-xx connector blocks which are cable connected to the KSU

maximum distance allowed from the KSU to a station is

1500 feet using #I24 gauge, twisted-pair cable.

equipped with a retaining clip. This clip is designed to secure the matted 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 un-snap it before the connectors can be separated.

DSSIBLF

The optional DSS/BLF console may be installed at any

station port to work in conjunction with a companion station connected to the adjacent port (e.g.; port 10 for station and port 11 for console).

The installed distance limit between the KSU and a con-

sole is the same as that specified for a regular station.

Connect all four wires (voice pair and data pair) of the

console cable to the station connector block. The voice pair connections of the console can be used

simultaneously to enable a PA port function. Refer to the paragraph in this chapter headed Area Paging In-

terface - Station PA Port. Per that discussion, wire a PA

amplifier input to the DSS/BLF console voice-pair at the

connector block clip terminals. Use an audio matching transformer, as discussed in the referenced paragraph

and Figure 2-3, to provide isolation. If an enable signal

is required with the particular PAequipment being used, the console and PA equipment connections are limited to station ports 23 and 25.

The DSS/BLF console port must be programmed as a

DSSIBLF port (see Chapter 3 for programming details)

before console operation can take place. The console port must be also programmed as a PA port if a PA

amplifier has been connected to the voice pair as part

of the system.

Busy Lamp Field Stations An optional keyset is available which is equipped with

a 14 station Busy Lamp Field (BLF). Up to eight BLF stations can be connected to the system. A BLF station

Power Failure Station Connection

The system provides a tip and ring-pair connected to

line 1 as an emergency power failure circuit. This power

failure pair is available at clip terminals on connector

block J-l as detailed on Table 2-l and Figure 2-4. A power failure pair is only active durfng a commercial power failure. An industry standard, single-line telephone, such as a Comdial model 2500-xx, can be connected to a power failure pair and used to provide communications capability until the AC power to the system is restored.

A-Lead Control Device Connection

The KSU can detect an A-lead

nal when it is applied to lines 7 and 8. An A-lead con-

trol device can be bridge-connected to these lines via

clip terminals on connector block J-2 as detailed on

Table 2-1 and Figure 2-4.

Data Device Connection When a serial data printer is used for SMDR and COS

printout, connect it to clip terminals on connector block J-l as detailed on Table 2-1 and Figure 2-4.

The distance between the device and the KSU can be up to 500 feet in a quiet electrical environment. Shielded cable may be required at some sites for long runs. For longer distances, a limited distance modem must be used to relay the data communications between the KSU and the 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:

The installed distance between the KSU and the

BLF station must be limited to 1000 feet or less.

The data-line paired station port cannot be used as

a BLF station connection or as a regular station

connection. Data-line pairing is: 1 O-l 1,12-13,

15,16-17,18-19,20-21,22-23, and 24-25.

The overload paired station port cannot be used as

a BLF station connection but can be used as a regular station connection. Overload pairing is: 1 12, 1%13,14-16,15-17, 18-20,19-21,22-24, and

SYSTEM PROGRAMMING

GENERAL INFORMATION

Class Of Service (COS) programming consists of setting the Class Of Service (COS) operating conditions. COS programming is divided into the following three major categories: System COS, tine COS, and Station COS.

All COS programming commands must originate at station 10. No COS programming commands can

The system can be defaulted to a standard class of

be accepted from any other station connected to the

system. COS programming causes station 10 to default to a square condition (line select key 1

selects line 1, key 2 selects line 2, etc.). It is recommended that station 10 always remain in a square

conditionto avoid possible programming confusion.

COS programming does not require that a sequen-

tial process be followed once the base level

The following system default conditions are set: program entry mode has been established except where noted herein.

The system defaults to preset characteristics when it is initially powered up or whenever programmed

to do so. If the default characteristics, or any other

previously set characteristics, are satisfactory,

those portions of the programming sequence may

be omitted. Prior to taking any programming action, record the

system, line and station COS conditions on Table

3-1,3-2, and 3-3 (included at the end of this chap-

ter). Also, record all toll restdction requirements on Table 3-4.

THE PROGRAMMING STEPS MUST BE PER-

FORMED WITH LESS THAN 17 SECONDS OF DELAY TIME BETWEEN KEYSTROKE OPERA-

TIONS. A delay of longer that 17 seconds causes the KSU programming mode to time out.

Flgure 3-3 found at the end of this chapter provides a quick-reference flow diagram of the class of ser-

vice programming requirements.

Programming is the same for both the model 0616X and 0816X key systems. The only difference be-

tween these two models is the number of lines which each serves (six or eight).

BASE LEVEL PROGRAM ENTRY MODE

The first step in a COS programming sequence is to enter the base level programming mode. Once in

this mode, COS can be set as desired.

c&ate that the base level programming mode is

entered.

tion that the base level mode is active.
