GENERAL

INTRODUCTION

The Commander AN-61 6 is an electronic key telephone system providing 6 exchange lines and 16

stations. It is an electronic system using hardware and software modules packaged to provide various

economical solutions. The stations have a very modern and stylish appearance.

The main equipment and the stations are controlled by microprocessors with masked programs providing a

wide range of facilities demanded by the users of key systems.

*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.

0Handle

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).

0Components 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,

PBAs

must ALWAYS be

inserted into a conductive ANTI-STATIC bag and placed in the protective container provided with the

new item. In the case of the CPB-AN remove the battery and package separately.

These procedures apply equally to both working and faulty

PBAs.

Careless handling, storage and

transporting will cause secondary or future faults.

To prevent the likelihood 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.

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.

CPB-AN BOARDS

If this PBA is 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 CPB-AN power up, i.e. power on.

TMB-AN BOARDS

If this PBA or the CPB-AN PBA is replaced, then the system clock is lost and must be

reprogrammed.

1.2 FEATURES AND FACILITIES

1.2.1 Direct Exchange Line Access

In general, any station can access any exchange line to answer an incoming or make an outgoing call. Up to

8 Exclusive Exchange Lines may be provided each of which can be accessed by one station only.

1.2.2 Last Number Redial

The user may recall the last number

dialled

by dialling

“+”

after seizing an exchange line and pressing the

Dial Control

(DC)

key.

AN-61 6

ISSUE

1.2.3 Saved Last Number

In addition to Last Number Redial a number may be saved and this number will not be erased until a new

number is saved.

1.2.4 Multiple Exchange Line Answer

The status of each exchange line is displayed at every station facilitating the possibility of answering an

incoming call at every station. The only exceptions are Exclusive Exchange lines, which appear at only one

station.

1.2.5 Conference Call (Simultaneous Outside Call)

A conferencing facility is provided which allows two internal stations to be connected to an exchange line

or two exchange lines to be connected to an internal station.

1.2.6 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 6 classes of barring.

Class A

Unrestricted

ClassB

Barred to ISD

Class C

Limited allowed STD and ISD codes

Class D

Barred to STD

Class E

Barred outgoing access when the system is installed behind a PABX

Class F

Intercom calls only.

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 form of cost control is provided by a facility allowing access to selected lines. Each station may be

denied access to particular exchange lines for outgoing calls.

1.2.7 Exchange Line Request

When all lines in a group are busy the user may request the next available exchange line in a particular

group. Up to a maximum of 6 groups can be allocated for this purpose.

1.2.8 Tie Lines

By use of a 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.

1.2.9

Hold

Both manual and automatic hold are provided by the system. 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 an

exchange line on Exclusive Hold, no other station can accept the call.

Exchange lines are automatically placed on Hold when either ICM or a DSS key are operated in order to

make an intercom call.

1.2.10 Automatic Ring Back

When an exchange line is put on I Hold or Exclusive Hold longer than a pre-set time the call is rung back to

the holding station.

1.2.11 Transfer

A manual transfer is the most often used method of 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.

Another method of transferring calls is without announcing. After transferring the call by an intercom call,

the transferring party presses the HOLD key. The called station then presents the call as an incoming call

while all other stations show that the exchange line is busy. If the call is not answered within a set time it

will return to the original station.

1.2.12 Call Forwarding

Intercom calls and exclusive line calls are forwarded to a pre-assigned station after this facility has been

activated using the DND key.

AN-61 6

ISSUE 1

1.2.13 Repertory Dialling

Basic and On-Hook stations are provided with 8 DSS keys which can be used to store frequently used

numbers. Numbers with up to 20 digits can be stored.

Handsfree stations are provided with 16 DSS keys and thus can store up to 16 numbers.

The stations may store and recall numbers at any time.

1.2.14 Abbreviated Dialling

A maximum of 60 numbers, up to 20 digits each, can be stored as common use abbreviated numbers.

These numbers can be accessed at any station by seizing an exchange line, pressing the DC key and

dialling the abbreviated code corresponding to the number required. The abbreviated dial code is a two

digit number between 10 and 69.

1.2.15 Privacy

Privacy is provided for intercom calls as well as the exchange lines. The only exception is that certain

stations can be given the facility of breaking into exchange line and/or intercom calls. The stations with this

facility are determined by system programming.

1.2.16

Night Switching

Operation of the

‘n\

TR key at station 10 directs ring signalling for all incoming calls to the programmed

Night Transfer station(s).

1.2.17 PBX Recall

Two methods of PBX Recall are available, Earth Recall or Switchhook Flash (Timed Loop Break).

1.2.18 Automatic Pause Insertion

If the system is connected to exchange lines via a PABX, a pause of pre-determined length is inserted

between the PABX access code and the remaining digits when using either abbreviated dialling, repertory

dialling or redial.

1.2.19 Power Failure

When the power fails the exchange lines are automatically switched through to pre-assigned stations. In

this condition the pre-assigned 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.

1.2.20 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.

Each exchange line can be individually set to dial out using decadic or VF dialling.

While dialling out on an exchange line assigned decadic dialling, the user can change to VF dialling at any

stage, by pressing the

‘#’

key.

1.2.21 Intercommunication Between Stations

Each station is able to establish an internal (intercom) call to another station by dialling the desired station’s

number or by pressing the desired Direct Station Select (DSS) key.

1.2.22 Alternate Point Answering

Any other station within the same internal paging zone can answer an intercom call to another station by

lifting the handset and pressing the BREAK key.

1.2.23 Intercom Conference

A station may add another station onto an existing intercom call to set up a three party intercom

conference using the

ADON

feature key.

1.2.24 Intercom Camp-On

When a busy tone is heard after making an intercom call, pressing the ‘*’ key will place the call in the

Camp-On mode. When the called station hangs up, the intercom call will be automatically established

provided the originating station has remained off-hook.

AN-61 6

ISSUE 1

1.2.25 Intercom Call Back

If the station in the Intercom Camp-On mode hangs up, then the Intercom Call Back feature is activated.

When the called station becomes idle a signal call is made back to the originating station. Responding to

the signal call will re-initiate the original intercom call.

1.2.26 Follow-Me

Intercom calls can be transferred from any station to another station.

1.2.27 Handsfree

Talkback

on Intercom Calls (optional)

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 MIC key.

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

1.2.28 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

”

I’.

The caller will hear ring tone and the called party must answer

by lifting the handset and operating the ICM key.

1.2.29

Message Waiting

A visual indication may be left at an unattended station to indicate that a message is waiting at another

station. Pressing ICM and dialling “0” at the message left station will route the call to the station originating

the message.

1.2.30 Priority Break-In (optional)

Break-In is available in three levels of priority, programmed on a station by station basis. Break-In can be

restricted to signal calls, intercom calls or intercom and exchange line calls.

1.2.31 Paging Calls (optional)

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 three zones. Stations are

programmed to be in one of the zones when the system is installed.

EXTERNAL ZONE PAGING calls are broadcast over external loudspeakers.

1.2.32 Meet-Me Paging (optional)

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

*‘*I’

button to be automatically

connected to the caller. The caller must have pressed the asterisk

‘I*”

button following the announcement.

1.2.33 Meet-Me Conference (optional)

Up to five stations in the same internal paging zone can take part in an intercom conference. The

conference is established by originating an internal zone paging call and pressing the ADON key. The

conference can be joined from any station in the same zone by lifting the handset and pressing the ADON

key.

1.2.34 Music On Hold (optional)

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.

1.2.35 Background Music (optional)

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.

1.2.36

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.

AN-61 6

ISSUE 1

1.2.37 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.

1.2.38 Do Not Disturb (optional)

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.

1.2.39

Off-Hook Signalling (optional)

The system can be programmed to provide audible indication of incoming intercom and exchange line calls

to a station while it is in the off-hook condition. This facility is programmed individually for each station.

1.2.40 Warning Tone (optional)

The system can provide a warning tone at three minute intervals during exchange line conversations.

1.2.41 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 Off) and system facilities

(Do

Not Disturb, Monitoring, Message Waiting, Speaker On etc.). The Handsfree Station has a Busy Lamp

Field

(BLF)

which displays the status of each station in the system.

1.2.42 On-hook Dialling

Handsfree and On-Hook stations may originate and monitor the progress of a call through the station

speaker without lifting the handset.

1.2.43 Handsfree Station

Handsfree Station provides the user with full handsfree operation for every type of call. It has a display

which can show time of day, date, dialling information stored in repertory and abbreviated dial locations,

duration of the call and the

dialled

number whenever dialling occurs. The Handsfree Station also provides

three alarms which can be set independently.

The Handsfree Station has 16 DSS keys, 8 more than the On-Hook and Basic models. It incorporates a

Busy Lamp Field

(BLFI

which provides the user with the information on the status of each station and line in

the system.

1.2.44 Headsets (optional)

Provision may be made to connect a lightweight headset to On-Hook or Handsfree stations. The handsfree

facility is lost if a headset is provided on a Handsfree station.

1.2.45Standard Telephones

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

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