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
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
to
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
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
to review further data. To terminate the review of a data category dial
then
For type of exchange line assignment, operate DSS key 34, dial the line number, then
To review other lines dial
line number,
Terminate review of data category by
dialling
For station assignments (except call forwarding and audible signalling, which are similar to
system assignments), operate the associated DSS key, dial the station number, then
To
review other stations dial
station number,
To terminate review of data category dial
For access barring data (except number length limiter, which is similar to system assignments),
operate AC then the associated DSS key. Review digits one by one by dialling
to display the
next code dial
To terminate the data category dial
till the associated DSS LED goes off.
When data has been checked depress the programming button to return the system to operation
mode. Check that the MW LED goes off.
Unplug the TPU when programming has been completed and connect the DSS Console if
provided with the system.
