    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.

    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.

  • Page 6: Facilities

    1.2 FACILITIES INTERCOMMUNICATION BETWEEN STATIONS 1.2.1 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.
  • Page 7 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.
  • Page 8 NIGHT SWITCHING 1.2.19 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.
  • Page 9 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.

Press the DC Key (10) and dial the abbreviated number (from 10 to 25) corresponding to the telephone number you wish to dial. When dialling stops due to a pause, wait for the new dial tone, then press the ‘*’ button to continue dialling the abbreviated number.
  • Page 16 TRANSFERRING AN EXCHANGE LINE CALL: Vocal Transfer Hold the Exchange Line and advise the required person to pick-up the call. Transfer by Intercom or Paging Call Place the call on hold and inform the required person via an intercom or paging call as described in Placing an Intercom Call and Paging.
  • Page 17 Alternatively, the station which is to join the conference may be called via the intercom. When the intercom call is answered, ask the person called, to lift the Handset (1) and press the ICM Key (13) or the Exchange Line Key (7) you are using. Press the ADD ON Key (9) again to begin the conference.
  • Page 18 HOT LINE CALL(SYSTEM OPTION): Only two stations are connected to a Hot Line. To call the other station, Lift the Handset (l), and press the Hot Line Key. The Hot Line Status LED indicates busy. To answer a Hot Line call, the Hot Line Status LED indicates a call.
  • Page 19 ANSWERING AN INTERCOM CALL: A Single Tone Burst from the Station Speaker (2) signals an intercom call. The originator of the call can be heard via the Station Speaker (2), “Voice Calling”. The Intercom Status LED (13) will indicate; Microphone-on, or Microphone-off.
  • Page 20 DO NOT DISTURB (PROGRAMMABLE OPTION): This facility is a programmable option and may not be allocated to all stations. A single operation of the DND Key (12), while the handset is on-hook, puts the station into Do Not Disturb mode The DND Status LED (12) indicates Do Not Disturb busy.
  • Page 21 PAGING: Three types of paging calls may be made. ALL CALL PAGING This method is used to make an announcement over the Station Speaker (2) of all stations and through the external loudspeakers, if equipped. INTERNAL ZONE PAGING (PROGRAMMABLE OPTION) This method is used to make an announcement through the Station Speaker (2) of the stations included in one of four zones.
  • Page 22 BACKGROUND MUSIC CONTROL: When the Handset (1) is on-hook the ‘I#” button is used to turn the Background Music on and off by alternate depressions. The volume of the Background Music is regulated by the volume control at each station. POWER FAILURE: During power failure the exchange lines are automatically switched through to preassigned powerfail stations.

If necessary adjust the speaker volume level using the Volume Control (33). Press the ON/OFF Key (31) again to terminate the call. To transfer the conversation to the station Handset (11, simply lift the Handset (1).
  • Page 29 Answering an Exchange Line Call : There is no facility to directly answer an Exchange Line Call. Exchange line calls must be transferred to an Internal Extension using the ADD ON Conference facility at a Key Station, or by a signal call from a DSS Console. Transferring an Exchange Line Call : An Exchange Line Call transferred to an Internal Extension can be transferred to a Key Station or Internal Extensions as follows:...

    2.6 POWERING UP THE SYSTEM When the system has been cabled and terminated and all printed circuit boards have been correctly set-up and installed, power-up the system. Before installing the stations measure the voltages at the 610 sockets to ensure that the cabling is correct.

  • Page 94: Programming Data

    2.7 INSTALLATION PROGRAMMING 2.7.1 Programming Data When the system is powered up for the first time, programmed data must be initialised. To initialise data, turn power off and set the SW1 switch on the ECMB board to the OFF(M) position. Turn power on, wait for ten seconds, then set the SW1 switch to the ON(S) position.

    2.7.3 Modifying Programmed Data Except for access barring, programmed data can be re-written as it is checked. If incorrect data is found whilst checking programmed data, dial new data from the DSS station (when OFF HOOK). The new data will be shown in the display on the DSS console. Dial “*” to write in the new data, then continue with checking programmed data.
