Common Audible and Auxiliary Station Interface

------

Two sets of relay closure dry-contact points are available at the J-l

and J-2 station connector blocks.

One set (J-l connections) provides a dry-contact closure whenever

any of the TELCO/PBX 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.

A typical connection is illustrated in Figure 2-2. Refer to the paragraph headed Area Paging Interface for a discussion for using

GENERAL INFORMATION

Class Of Service (COS) programming consists of the following major

categories: General System COS, Toll Table Entry, Line COS, and

Station COS.

All COS programming commands must originate at a 22 Line/Feature

process be followed once the base level program entry mo e has been

established except where noted herein.

Station COS programming does

follow a sequential process.

Prior to taking any programming action, determine the system, line

and station

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

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 SMDR output

lines of the KSU.

SPECIAL PROGRAMMING

FOR SINGLE-LINE KEYSETS

Several programming steps under COS programming must be observed

proper operation of a Single-Line Keyset.

@When the system is strapped for key system configuration, the

Single-Line Keyset is an intercom only station. It can be configured for private line only by programming the applicable

station port for the prime line automatic feature. When the port is

programmed with the prime line automatic feature, the Single-Line

the system is strapped for the multifunction (hybrid) system

configuration,

to originate outside calls with a Single-Line Keyset,

one or more lines must be programmed into a line group.

order to receive outside calls on a Single-Line Keyset, the call

be answered by an attendant using a multiline station and

transferred to the single-line station. Otherwise,

Alternately it can be programmed to have the prime line automatic

feature with ringing enabled at the prime line.

BASE LEVEL PROGRAM ENTRY MODE

The first step in any COS programming sequence is to enter the base

level programming mode from station port

or 11.

Once in this mode,

COS can be set as desired. To

TOLL

In order for toll restriction to take effect, the following three-fold process must occur.

One or more toll tables must be entered.

l Toll tables must be assigned to all appropriate lines. l 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 invoke any toll restriction.

TABLE ENTRY PROCEDURE

Determine the types of dialing restrictions which must be imposed on the system. Typically, this includes access codes which result in toll charges, and certain local numbers as desired.

2. 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.

4. 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 a/ways 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.

l Example A: Provide a simple and broad toll restriction format by creating a DENY table

with two entries: Entry (1) = 1 Entry (2) = 0. This format prevents all long distance and

operator calls.

l Example B: Prevent the dialing of all numbers within the (804) area code, while allowing

the dialing of one specific number within that area code, by entering 1804 in a DENY table and 18049782200 in an ALLOW table. Alternately, allow all numbers in the 978 exchange by entering 1804978 in an ALLOW table.

Press the # key in place of a particular digit to condense a range of numbers into one entry.

character is a “match-anything” digit, and can be included in an entry in either a DENY

table or an ALLOW table.

l Example A: If

and 397 dialing is to be prohibited, list one entry of

on a

DENY table to cover them all.

l Example B: Since area codes typically have a 1 or a 0 as a middle digit, prevent long

distance calls to those area codes by entering 1

and 1#0# in a DENY table.

Since it is important that emergency numbers never be restricted, always 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.

Maintenance

If erratic light indications or ring signals occur at a paired station,

an open data pair at either station may be the fault. A

station with an open data line may work properly on a short loop but fail on a long loop.

Test the wiring of stations showing this symptom

per the checkout procedure given in Chapter 2.

If a fault occurs which causes more than 300 ma. of current to be drawn,

the overload paired stations are disabled by circuit action.

Disconnect the disabled stations and reconnect them one at a time to

isolate the faulty one. Failure Analysis

----- ---- ___ And Station

Figure 4-2 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
