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

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. 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

Page 8

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

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. 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).

A cable with polarised connectors provides the connection between the power supplies and the main equipment. Power-on lamps, switches and fuses are located on the front of the power supply. Figures 18 shows an external view of the power supply.

Stations

There are two types of stations; standard stations and powerfail stations. Standard stations contain a telephone network including handset, a dial key pad,

non-locking function keys, status lamps, a microphone, a speaker, a volume control and electronics to control the stations operation.

Powerfail stations, in addition to the above, contain a powerfail dial either decadic or DTMF and an electronic buzzer to signal incoming calls during power failure. One powerfail

station maybe equipped for each exchange line connected to the system.

Figures 19, 20, 21 show the stations.

DSS Console (Fig. 22, 23)

Primarily the DSS Console provides facilities required for an operators position. That is, a simpler means of answering and transferring calls, and a display of the status of each station in the system.

The DSS Console consists of a series of single function keys and direct station selection

(DSS)

keys with corresponding status lamps, a speaker for audible signalling, and a 4 digit

display to show held exchange lines and the station holding the exchange line.

NOTE:

As systems are programmed using a special DSS console, a DSS console socket must always be wired. The modified console is known as a Test and Programming Unit

(TPU-N).

Incoming Local Exchange Lines or PBX Lines are connected to the main equipment. A Call Metering Unit may be used to record meter pulses sent from the local exchange. Tie Lines are connected via a RTIU.

The Power Supply provides all the power necessary to operate all system modules with the exception of the RTIU which has its own power supply.

Powerfail Bells, if used, are automatically connected across incoming exchange lines when the

power fails. Handsfree Consoles are equipped on a per station basis and are directly connected to the

station. They have no direct connection with the M.E. The following devices may be connected to M.E. ports, Stations, DSS Consoles, Internal

Extensions and Remote Extensions. Standard stations, powerfail stations and the DSS console are connected to the M.E. by 4 wires, one pair is the speech pair and the other pair is for data transmission and power feed to the station.

Standard decadic telephones, Internal Extensions, are connected to the M.E. by a single pair of wires, audio communication and decadic signalling is performed on this pair. A special

interface and Ring Generator Unit is provided so standard telephones can be used. Remote Extensions are connected to the M.E. via the RTIU. The

RTIU

has a 4 wire connection to the M.E., (one pair voice, one pair data) and a 2 wire connection to the remote extension for voice and decadic signalling. Cards in the

RTIU

perform the 4 wire to 2 wire interface.

CPU Control consists of the

280

micro-processor, ROM program memory, RAM working registers, timing and control circuitry. The CPU controls all switching and system data manipulation.

RAM Memory is used as working memory, to store site dependant data and to store abbreviated

dialling numbers. It is located on the ECMB cards and has a lithium battery to retain the data when power fails.

Power Failure Switch automatically connects exchange lines directly through to pre-assigned powerfail stations via the powerfail connection. At the same time the powerfail bell is connected

in parallel with the powerfail station.

Exchange Line Interface provides the d.c. loop termination of the exchange line, ring detect circuit, audio coupling transformer, dialling relay, line surge protection and distribution for tones and hold music.

Earth Recall Control is used to apply PBX earth to one wire of the exchange line pair. Dial Control module in one case, provides the VF tones, and in the other case, provides timing

and control circuits for the loop-disconnect decadic dialling, depending on the type of exchange lines used.

Tone and Music Source generates all internal system, tones and synthesises hold music, it also provides the input for background music.

Crosspoint Switch Network is made-up of semiconductor crosspoints and is distributed over a

number of cards. This circuit which decodes the CPU order to operate the crosspoints is

located on the EDTB card. Figure 10 shows how the crosspoint switch matrix is made-up.

Intercom Control controls the voice switching circuits for handsfree talkback. Station Interface provides circuits for transmission of voice and serial data between the

stations and the M.E. There is no B pair when using the E2WB card. Station Data Receive and Transmit contains microprocessors which control the transmission

of new status information from the main CPU and receive data of operations initiated at each

station. Paging Amplifier amplifies the systems audio signals for broadcasting through external

loudspeakers.

Telephone Network, transmission circuit and Handset are connected to the M.E. audio path by the A-pair.

The B-pair is used to transmit status information between the M.E. and the station and supply

power. Microphone signals for handsfree

talkback

are phantomed between the A and B pairs.

Data Receive Transmit converts transmitted data into logic levels for the CPU. Power Regulator takes power from the B-pair to supply the station circuits. CPU Control supervises all operations at the station, informs the main equipment of station

status and displays the status of system parameters, at the station. Intercom Network contains the amplifiers for the station Speaker and Microphone and a solid

state switch which the CPU operates to cut-off the microphone.

Off Hook Signalling Module generates ring signaling under the control of the CPU. Status Lamps show the status of system facilities and are controlled by the CPU. Station Keys are used to envoke system facilities and the CPU constantly monitors their status.

Dial Pad is used to input

dialled

digits. During normal operation the operation of the dial is monitored by the CPU and the information is conveyed to the main equipment. Under powerfail conditions the dial pad operates the Powerfail Dial which outputs either decadic pulses or DTMF tones onto the A-pair for signalling on the exchange line connected to that station.

FIGURE 32 LIMITATIONS ON WALL MOUNTING

All items of equipment must be located in positions which allow good access for maintenance activities. The customer is responsible for providing satisfactory lighting for installation and

maintenance activities at the equipment. When wall mounting equipment, allowance should be made for at least 30 cm clear wall space on each side and 1 metre of clear floor space in front of

the units. The Main Equipment, Power Supply, System Distributing Frame, Call Metering Units, Remote

Extension and Tie Line Interface Unit and Ring Generator Unit must be mounted on a wall at

least 38 cm from the floor and no higher than

1.8m

from the floor as indicated on figure 32.

The customer will provide a single phase 200-250 volt, 10 amp, 50 Hz AC general purpose outlet within 1 metre of the equipment. The power outlet must be correctly earthed.

Due to the weight of the equipment, particularly the Power Supply, care should be exercised in the selection of the mounting position.

Both the Main Equipment and the Power Supply are to be wall mounted as shown in figure 32. Equipment may be mounted directly to solid brick walls or similar. For hollow structures, such as plaster-board walls or partitions, a suitable sized back-board should be firmly secured to the wall studs (or other supporting members) and the equipment

ft,xed

to the back-board.

Where equipment is to be mounted on solid brick walls or similar, suitable masonary anchors should be used in lieu of the mounting screws.

Further mounting details for the Main Equipment and Power Supply are provided in section

2.3.1 and 2.3.2 respectively. While mounting equipment refer to the drawings of the components in section 1.5.

System Distributing Frame

The S.D.F. provides a common terminating point for the main equipment, stations and other

ancillary equipment. It also provides for any strapping necessary for provision of facilities.

The S.D.F. is constructed using the Krone LSA Plus terminating system. The terminal is an

insulation displacement type terminal and is available in 10 pair modules. The modules provide the facility of opening the circuit for monitor or test purposes without the need to disturb the terminations. See figure 35.

In order to mount the station on a wall, a Wall Mounting Bracket is required.

Mount the bracket on the wall by means of the four screws which are supplied with the bracket. The bracket is located so that the edge with the two retaining tabs is at the top. Hole centres are shown in figure 38.

Next, remove the front panel of the station with a screw driver, loosen the screws and remove the case moulding from the base moulding.

Insert the hanger into the square hole (Point A in figure 39). This hole is located in the recess on the top moulding used for the receiver of the handset. Fasten the metal retainer

from inside the housing using the screw provided (Point B in Figure 39). After fixing the

handset hanger to the top moulding, reassemble the top moulding and the base moulding,

tighten the screws and replace the front plate.

Mou’nt the telephone plug and socket on the wall in the centre of the wall mounting bracket.

The line cord should be gathered together and placed inside the wall-mounting bracket.

Now clip the station on to the wall-mounting bracket as shown in figure 39. This is done by

fixing the upper portion of the bracket into the two square holes located in the base plate of

the station. Then, push the station base towards the bracket until it clips into the lower portion of the bracket.

2.4.3.2 Krone Terminating Tool

FIGURE 45 KRONE TERMINATING TOOL

The terminating tool shown in figure 45, is a spring loaded percussion device incorporating scissor action wire cutters. Termination and wire cutting are achieved by a single motion. Physically the tool can only be inserted one way, thus preventing the installer cutting the wrong side of the wire.

The “hook end” attachment is used for disconnection of the wire and for removing disconnect plugs.

The “blade end” attachment is used to remove the module from the backmount channel. The blade is inserted into the slot, at the ends of the module, to unseat the locking tabs on each side of the module from the backmount channel. The module can then be pulled off the backmount channel.

RING GENERATOR UNIT

FOR TWO E2WB-C BOARDS

The E2WB-C board replaces an ESTB-C board to provide four internal extensions. A Ring Generator Unit is required and is capable of supplying ring voltage for two E2WB-C boards. The

RGU and internal extensions are connected to the main equipment via the SDF. The stations corresponding to the ESTB-C board position are replaced by internal extensions and the RGU when using the E2WB-C board. Refer to figure 53 for an example.

The A-pairs are connected to two-wire internal extensions, the B-pair of the first internal

extension of each board is connected to ring voltage from the RGU (16Hz and OUT), and the

B-pair of the second internal extension is used to supply power to the RGU (+ and

G).

If the RGU is used to provide ring voltage to two E2WB-C boards, then the supply voltage must

only be connected from the first E2WB-C board. Refer to figure 54.

The loop limit for an internal extension using the E2WB is 700 Ohms corresponding to 4km of

0.5mm cable.

2.4.14

External Music Source and Background Music

Connect the external music source input to Ml/M2 from the

604/611

plug and socket via the SDF. The music source connection has an input impedance of 600 ohms. The level of the incoming signal must be between 50 and 300

mVrms.

2.4.15

External Paging Loudspeakers

The loudspeakers are connected to a

604/611

plug and socket and wired to the amphenol connectors via the SDF. Connect the external paging loudspeakers to the LOUD SPEAK connections 1

LSl

and 1 LS2 for external zone 1 and

2LSl

and 2LS2 for external zone 2.

Relay contacts are provided for each external paging zone. They are designated

1Sl

and 1

for zone 1 and

2Sl

and 2S2 for zone 2. The relay contact rating is 1.25A at 24Vdc.

The output power of the loudspeaker amplifier is 2 watts into an 8 ohm load.

2.4.16 Alarm Detector

Connect the alarm detector to

ALMl

and ALM2 on the amphenol connector via the

604/611

plug and socket and the SDF. The system detects the opening or closing of a dry metallic contact, depending on system programming.

2.5 BOARD INSTALLATION INSTRUCTIONS

Before inserting boards into the ME rack, the following preliminary work is required.

*WARNINGS*

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, PBAs 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 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. Do not short or bridge between terminals as this will cause fuses on the ESTB boards to blow.

If these PBAs 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, BTB-A, (without loss of any programmed data) while the ECMB power is on.

The press button

(SW41

must be pressed to reset the crosspoints of the system after

replacing ESTB or ELNB boards when the power is on.

ASSIGNING THE DSS STATION(S)

SW3 is used to assign the number of the first DSS station, SW2 is used to assign the number of the second DSS station if two DSS consoles are used. When the second DSS console is not equipped set SW2 to all ones. The first DSS console must always be assigned. The bits 1,

2,3 &

4 assigns the TEN’s number and bits 5, 6, 7 8 8 assign the UNIT’s number. Once a DSS station

number is assigned, the DSS console number is automatically the DSS station number plus one. Numbers equal to or greater than 36 (N 616), 55 (N 1236) and 79 (N 2260) are prohibited for use as the DSS station. The N 616 is provided with a dedicated DSS console port (number

361,

therefore, it is recommended that it be used so that the full 16 station ports may be used.

In this case the DSS station port will be set as 35. The numbers are set as follows:

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. The initial values of the data are given in section 2.7.6.

A unit designated as a Test and Programming Unit

(TPU-NJ

has been developed. The TPU-N must be inserted into the DSS Console socket when programming or testing the system. To enter programmed data the system must be placed in programming mode. To do this, press the programme enable button using a pencil through the hole of the TPU-N.

The MW LED on the console will light to indicate that the system is in programming mode. When the system is in programming mode normal operations are halted - existing calls are

maintained, incoming exchange line calls will ring but cannot be answered unless you go out of programming mode. No new calls can be made. Programmed data can be entered using DSS keys to select a data category, and the dial of the DSS station (when OFF HOOK) is used to enter the relevant data. Programme data is indicated by the TPU display, and the associated DSS LED will light to indicate which data category is being programmed. Note that if two DSS console ports are provided, programming is possible from the first console only.

Data is programmed as follows: place the system into programming mode. Operate the DSS key associated with the data category to be programmed and the LED should light. Enter data by dialling from the DSS station (OFF HOOK). Dial

“*”

to send the write command and dial

“#”

terminate a data category or data block within a category. When data programming is completed, depress the programming button to return the system to

operational mode and the MW LED will go OFF. If there is a fault in the programmed data, alarm tone is heard from the TPU, the DSS LED associated with the faulty data category

WIII

light and

the system will not return to operational mode. If this occurs, the programming button should be

despressed again to return the system to programming mode.

The faulty data category must be reprogrammed

2.7.2 Checking Programmed Data

Programmed data may be reviewed as follows: Place the system in programming mode by depressing the programming button on the DSS Console ensure that the MW LED is lit, and take the DSS Station OFF HOOK. Data is indicated on the TPU display in the same format as for programming data.

For system assignments, operate the DSS key associated with the data category. The associated DSS LED will light and data will be displayed on the console. If the data is in more than one part dial

‘I*‘”

to review further data. To terminate the review of a data category dial

“*‘”

then

‘I#“.

For type of exchange line assignment, operate DSS key 34, dial the line number, then

“*‘“.

To review other lines dial

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. Data is erased by dialling “00” as new data.

For access barring, incorrect data must be reprogrammed. A code may be erased using the following procedure; operate the associated DSS key, dial

‘I#”

to step through to the code to be modified, erase the code by dialling

“*I”.

To programme new

data use the procedure described in section 2.7.5.14.

It is not possible to programme some data categories while system facilities are active. Table 15 shows the conditions under which the system will not allow data to be programmed. If this occurs the associated DSS LED will not light when the DSS key is operated.

When using a 1236 DSS console for programming the unmarked key between MW and NT

must be used instead of key 56.

The display is divided into two fields of two digits each.

.--

Enter “00” before a station number to specify a exclusive line, and enter two station numbers to specify a hot line between those stations.

NOTE: 1 When a hot line is provided the corresponding exchange line must not have an

exchange line connected. The exchange line circuit is used to provide signalling tones.

An exclusive line must not be assigned to a remote or internal extension.

Example: Provide a exclusive line using line-3 (exchange line 23, 2260 system) for station

number

25.

2.7.5.10 EARTH RECALL OR SWITCHHOOK FLASH

(DSS

35)

When the system is connected to a PBX, earth recall or switchhook flash may be assigned.

DSS key 35 is used to assign the required facility earth recall or switchhook flash. If neither earth recall nor switchhook flash is required, programme

“0”.

If earth recall is required, programme

“1”.

If switchhook flash is required, programme “2”. Example: Earth recall

TYPE OF EXCHANGE LINE

(DSS

34)

‘-

Each exchange line connection must be defined as a local exchange connection or a PBX connection. This information is necessary for redial and access barring. Each line must be specified in sequence, lines must not be omitted. This also applies when equipping the system.

NOTE: For exchange lines connected to a PBX the code used to get an outside line (trunk access code) must be programmed using DSS key 44 as part of the access barring data.

DSS key 34 is used to allocate each exchange line, first enter the exchange line number, including leading zero.

If the exchange line is connected to an exchange, programme

“0”.

If the exchange line is connected to a PBX line, programme “1” Example: Exchange line 1 is connected to an exchange.

Exchange line 2 is connected to a PBX line.

2.7.5.12 EXCHANGE LINE AUDIBLE SIGNALLING (DSS 20 to 28 and NT)

All stations have visual indication of incoming calls, but audible signalling is a programmed option. The options are:-

(i) COMMON SIGNALLING; stations assigned to common signalling will hear audible signalling

whenever there is an incoming call on any exchange line. A maximum of 10 stations can be

assigned to common signalling. (ii) GROUP SIGNALLING; exchange lines connected to the system are divided into 4 groups

with a maximum of 10 stations assigned to each group. Stations may be assigned to only one of the groups. An incoming call on an exchange line in group 2 will only signal to stations assigned to group 2.

(iii) NIGHT TRANSFER; this mode operates when the NT key on the DSS Console is operated. Effectively this adds’assigned stations (up to 20) to the common signalling group while the system is in night transfer mode.

In general, a station may be programmed to only one of the above options

(i),

(ii) or (iii). The only exception is that stations assigned to group signalling may also be assigned to night transfer signalling. Stations assigned to common signalling must not be assigned to night transfer - this will result in a programming error.

2.7.5.12.1

COMMON/GROUPED SIGNALLING MODE (DSS 20)

DSS key 20 is used to programme the audible signalling mode for incoming calls. There are two modes of signalling, common signalling only, or common and group signalling together.

If only common audible signalling is to be used, programme

“0”.

If common and grouped signalling is provided, programme

“1”.

Example: Common and Grouped signalling.
