GENERAL

1 .l INTRODUCTION

The N 616, N 1236 and N 2260 are electronic key telephone systems providing 6 exchange lines and 16 stations, 12 exchange lines and 36 stations, 22 exchange lines and 60 stations, respectively. They are a family of key telephone systems using common software and hardware modules, packaged to provide various economical solutions. The stations have modern functional styling.

The main equipment, stations and DSS console are controlled by micro processors with masked programs providing a wide range of facilities demanded by the users of key systems.

A prominant feature of this equipment compared to previous key systems is the elimination of multi-wire cabling in favour of 4 conductor

pair) cabling.

*WARNINGS*

This equipment contains a considerable number of MOS, and other static sensitive components. To reduce the incidence of the premature failure due to static discharge, the following precautions MUST be taken:

Always ensure that power is disconnected before plugging

PBAs.

Always discharge static from yourself by touching a conductive part of the main equipment before handling boards.

Handle PBAs by the edge or by the handles. Do not handle PBA tracks, components

or edge connectors (contaminants introduced by fingers can cause corrosion and

high resistance connections).

Components are physically delicate. Finger pressure on a component can fracture,

but not necessarily break component leads: a future fault.

To protect against physical damage and damage due to static discharge,

PBA’s must

ALWAYS be wrapped in aluminium foil (e.g. cooking foil) and inserted into an ANTI-STATIC plastic bag and placed in the protective container provided with the new item. In the case of the ECMB remove the battery and package separately.

These procedures apply equally to both working and faulty PBA’s. Careless handling, storage and transporting will cause secondary or future faults.

To prevent the likelyhood of damage to electronic components, power should be switched off before working on the systems.

.--

The cabling between the Main Equipment and Stations is polarity sensitive. It is essential that the correct polarity be maintained from the Main Equipment to the Stations and pairs must not be swapped. Care must be exercised when checking voltages on cabling. Do not short or bridge between terminals as this will cause fuses on the ESTB boards to blow.

Power supplies are powered from the 240 volt mains supply and hazardous voltages are present within. Do not attempt to repair these devices in the field.

ECMB- A,B, 8 D BOARDS

If these PBA’s are replaced, all site dependant data and abbreviated dial numbers are lost. It will be necessary to re-programme the system.

The battery may be changed by removal of the daughter board (without loss of any

programmed data) with the ECMB power up, i.e. power on.

The press button

(SW4)

must be pressed to reset the crosspoints of the system after

replacing ESTB or ELNB boards when the power is on.

1.2 FACILITIES

1.2.1

INTERCOMMUNICATION BETWEEN STATIONS

Each station is able to establish an internal (intercom) call to another station by dialling the desired stations number.

Automatic intercom line selection is provided, this requires only one Intercom Line Key per station.

Assigned stations can call a particular station using a direct access key, Hot Line Key. In addition, each system has a capacity for two Direct Station Select

(DSS)

Consoles

incorporating a Busy Lamp Field (BLF).

1.2.2 ALTERNATE POINT ANSWERING (CALL PICK-UP)

Any other station can answer an intercom call to another station by lifting the handset and dialling the called stations number.

1.2.3

ADD ON CONFERENCE

A station may add another station onto an existing intercom call to set-up a three party intercom conference using the ADD ON feature key.

1.2.4 BREAK-IN, OVERRIDE

Executive Break-in is provided by Hot Lines. Hot Line calls have priority over all other call types. The DSS Console has priority to override an intercom call. An intrusion tone is signalled when the DSS Console overrides a call. The DSS Console may be programmed to override stations in

Do Not Disturb.

1.2.5

DIRECT EXCHANGE LINE ACCESS

In general, any station can access any exchange line to answer an incoming call or make an outgoing call. The only exception is exclusive lines.

Up to a maximum of 6 Exclusive Exchange Lines may be provided with the limitation of one per

station. An

ExecutiveSecretaiiaI

configuration can be arranged where only the secretary’s

station responds to

incomming

calls and the secretary may extend the calls to the executive

using an intercom call.

1.2.6

LAST NUMBER

REDIAL

The user may recall the last number

dialled

by operating the asterisk

‘*’

button after seizing an exchange line and depressing-the Dial Control (DC) Key. When the system is connected to a PABX via exchange lines, a 3 second pause is generated automatically when dialling through the PABX.

1.2.7

MULTIPLE EXCHANGE LINE ANSWER

The status of each exchange line is displayed at every station facilitating the possibility of answering an incoming call at any station. The exception being Exclusive Exchange Lines, which only appear on one station.

1.2.8

CONFERENCE CALL (SIMULTANEOUS OUTSIDE LINE CALL)

A conferencing facility is provided which allows up to three internal stations to be connected to

an exchange line or, two exchange lines connected to an internal station.

1.2.9 COST CONTROL

Three forms of cost control are available. The systems can perform Access Barring by analysis of

dialled

digits. Dialled digits are compared with codes preprogrammed into the system’s data

base. The system caters for 5 classes of barring.

Class A

Unrestricted

ClassB

Barred to ISD

ClassC

Limited allowed STD and ISD codes

Class D

Barred to STD

ClassE

Barred outgoing access when the system is installed behind a PABX.

N616,1236,2260

ISSUE 1

The second form of cost control is the use of a Call Metering Unit which records the metering

pulses on an exchange line basis. A third, but less useful, form of cost control is provided by a facility allowing No Access to a

group of Exchange Lines. This facility allows the exchange lines to be split into two groups and selected stations are not permitted to make calls using exchange lines in the second group.

1.2.10

TIE LINES

By use of a Remote Extension and Tie Line Interface Unit the system can handle two types of tie lines, Ring-in/Ring-out and Loop-in/Ring-out. The tie lines take the place of exchange lines.

1.2.11

PBX RECALL

Two methods of PBX Recall are available, Earth Recall or Switchhook Flash (Timed Loop Break). The key for this facility takes the place of an exchange line key.

1.2.12 TRANSFER

A manual transfer is required when transferring an exchange line call. The station holds the exchange line, notifies the other station using an intercom call and the station accepting the call must seize the exchange line by operating the corresponding exchange line key.

The DSS Console may perform a Revertive Transfer. After calling the other station using a DSS

key the attendant may operate the Signal Call (SC) facility. The call is then signalled at the transferred station. If the call remains unanswered after 20 seconds the call reverts to the DSS station.

1.2.13 HOLD

Both manual and automatic hold are provided in the systems. Indications are provided for the

Hold, I-Hold and Exclusive Hold conditions.

Stations are provided with manual hold by operating the Hold Key, I-Hold is indicated at the

holding station and Hold is indicated at all other stations. A second operation of the Hold Key will place the exchange line on Exclusive Hold, no other station can accept the call.

The DSS Console has an Automatic Hold, used when transferring exchange line calls to another

station. After answering an exchange line call the exchange line is automatically held when the

DSS attendant operates a DSS Key, an Internal/External Paging Key or the All Call Key.

1.2.14

CALL FORWARDING

Intercom calls and exclusive line calls are forwarded to a preassigned station after this facility has been envoked by operating the Do Not Disturb Key at the unattended station. A maximum of 4 pairs of stations can have this facility.

1.2.15

ABBREVIATED

DIALLING

Each station is provided with a 16 number store with a capacity of 16 digits for each number The station may store and recall numbers at any time.

1.2.16 PRIVACY

Privacy is provided for intercom calls as well as exchange line calls. The only exception is that the DSS Console has the posibility to override a handsfree talk-back intercom call, following an intrusion tone.

1.2.17 POWER FAILURE

When the power fails the exchange lines are automatically switched through to preassigned stations set-up by the wiring of the connectors on the main equipment. In this condition the

preassigined stations can accept incoming calls and originate outgoing calls. All other facilities

are inoperative. The system data base stored in CMOS memory is retained by a lithium battery.

1.2.18 AUTOMATIC RING BACK

When an exchange line is put on exclusive hold longer than a preset time the call is rung back to the holding station.

N616,1236,2260

ISSUE 1

1.2.19

NIGHT SWITCHING

Operation of the Night Transfer Key at a DSS Console directs ring signalling for all incoming

calls to the programmed night transfer station(s).

1.2.20

MESSAGE WAITING

A visual indication is displayed at an unattended station to indicate that a message is waiting at a DSS Console. A call to the DSS Console resets the message waiting indication.

1.2.21 SUPERVISORY TONES

The following supervisory tones are generated within the system:

Intercom Dial Tone Busy Tone Intrusion Tone Number Unobtainable Tone Ring Tone

1.2.22 MUSIC ON HOLD

Provision has been made for internally generated synthesized tones, or music from an external source, to be transmitted to a caller who has been placed on hold.

1.2.23

BACKGROUND MUSIC

Provision has been made so that music, supplied from an external source, can be transmitted over the station speakers and external zone paging speakers, if required. The music can be turned on and off at each station and is automatically turned off when the handset is off-hook.

1.2.24

PUSHBUTTON DIALLING

Each station is equipped with a push button pad. Dialling, Decadic or VF, is controlled by a centralised dialling facility in the main equipment. A dialling station signals to the centralised dialling facility via a data transfer and the decadic or VF signals are sent out on the exchange

line. During power failure, powerfail stations have decadic or VF dials switched in at the station.

1.2.25

STANDARD TELEPHONES (P-WIRE INTERNAL EXTENSION)

It is possible to connect 2-wire standard telephones with decadic dialling using a special

interface card and a ring generator unit in place of a 4-wire station interface card.

1.2.26 REMOTE EXTENSIONS (REMOTE STATION, P-WIRE TELEPHONE)

A remote extension can be connected to the systems using a Remote Extension and Tie Line

Interface Unit which provides the 4-wire to 2-wire conversion, generation of ring voltages and

tones. The remote extension must be a decadic telephone.

1.2.27 VISUAL INDICATIONS

A visual indication is provided at each station to show the status of exchange lines (Free,

Incoming ring, Hold, I-Hold, Exclusive Hold and Busy), intercom lines (Free, Busy and Microphone on), and system facilities (Do Not Disturb, Monitoring, Message Waiting

etc).

The

DSS Console has a Busy Lamp Field

(BLF)

which displays the status of each station in the system. In addition the DSS Console displays the number of the station(s) holding held exchange lines.

1.2.28 MONITORING (ON-HOOK

DIALLING)

Each station may originate and monitor the progress of a call using the station speaker without lifting the handset.

1.2.29 HANDSFREE

TALKBACK

ON INTERCOM CALLS

The called party has a full handsfree facility when called via an intercom call. A single tone announces the call and the voice of the calling party is heard through the station speaker, at the same time the called station’s microphone is activated and the intercom status lamp flashes to indicate the microphone is on. The microphone may be cut-off by operation of the DND key.

A volume control is used to adjust the sound level transmitted through the station speaker.

N616,1236,2260

5 ISSUE 1

1.2.30 PAGING CALLS

Three paging facilities are provided, All Call, Internal Zone and External Zone Paging. ALL CALL PAGING transmits an announcement over the station speakers of all stations and

through the external loudspeakers. INTERNAL ZONE PAGING calls can be made through station speakers to one of four zones.

Stations are programmed to be in one of the four zones when the system is installed. EXTERNAL ZONE PAGING calls are broadcast over external loudspeakers.

1.2.31 MEET-ME PAGING

The systems provide a facility which allows a person being paged to respond by simply lifting the handset of any station through which the announcement was heard and pressing the “8” button to be automatically connected to the caller. The caller must have pressed the asterisk ‘*’ button following the announcement.

1.2.32 FULL HANDSFREE OPERATION

Full handsfree operation is possible by adding a Handsfree Console to a station. This provides handsfree operation at that station for every type of call.

1.2.33 CALL SIGNALLING

Incoming calls are signalled by a tone caller through the station speaker. Different signals are provided for intercom calls and exchange line calls. Each station may be programmed to signal

when there is an incoming call on any exchange line or only on a group of exchange lines or it

may not signal for incoming exchange line calls. The volume control provides a means of

adjusting the volume of the tone caller.

1.2.34

ALARM SIGNALLING AT THE DSS CONSOLE

A supervisory or alarm device, which has as an output a set of contacts which open or close, can be connected to the system. When the device is activated a flashing LED and audible alarm signal will be indicated at the DSS Console. While in night transfer mode the alarm will be

indicated at the night transfer station(s).

1.2.35 DO NOT DISTURB

The system can provide a Do Not Disturb facility for all stations depending how the system is

programmed. Operation of the DND key puts the station in Do Not Disturb mode. This will turn off the background music, block all paging calls, send busy tone to intercom callers, stop audible signalling and forward calls to another station if so programmed.

1.2.36 KEY LABELS

The keys have transparent plastic covers which can be removed by hand so that a typed or

handwritten label may be placed under the cover for easy key identification.

1.2.37

SIGNAL CALL

If after placing an intercom call in the usual manner, there is no immediate response, the call

can be signalled using ring signalling by dialling an extra digit. The caller will hear ring tone and

the called party must answer by lifting the handset and operating the ICM Key.

1.2.38

PRESELECTION

A user may preselect the facility that is to be used by operating the facility key and then lifting

the handset off-hook, providing the handset is lifted within 5 seconds.

1.2.39 CALLS TO BUSY STATIONS

While a station is off-hook and busy on a call, muted incoming audible signalling may be heard

through the station speaker, depending on system programming. In this case the user may

decide to hold the exchange line he is using and accept the incoming call.

1.2.40

NUMBER PLAN

The systems have a fixed numbering scheme. Stations are numbered from 20 up to the

maximum system size 35

(616),55

(1236) and 79 (2260).
