Preliminary Procedures
After the case has been wall mounted, connect one exchange line, and two extension telephones (11
and 12)
Exchange Line 1 must be connected to EXCHANGE terminals marked CO1, line 2 to
CO2, line 3 to CO3, line 4 to CO4, line 5 to CO5 and line 6 to CO6.
A DTMF telephone (or Executive Terminal) must be fitted to EXTENSION terminals
marked ext.13. This is the Master Extension and is used for system programming.
Lift the handset at Extension 11 (a power fail telephone) and listen for PSTN dial tone,
before power up. Verify that you can directly dial external numbers, without the normal
prefix 0 for a line.
Power up Sequence
Turn on the 220 – 240VAC supply, then wait about 10 seconds.
Wait until the green LED on the front cover is on and flashing.
Call between Extension 12 and extension 11.
Make an exchange line test call to verify wiring between extensions, main unit and PSTN
exchange lines.
Set the system clock (see page 37).
If an Executive Terminal or Standard Terminal is fitted then log on the terminal by dialling
the code * 751 ext. #.
The Telephone System comprises a 220 - 240VAC Power Unit, MBU (Main Board Unit), MOH
Port, two PSTN Exchange Line Port, eight hybrid ports for Terminals or SLTs,
Expansion/Optional PCB Connectors, Ring Generator Circuit and MDF Connection Unit. A split
Main Equipment cover (Top cover/Side cover) is provided to allow individual access to the MDF
Connection Unit without access to the Main Equipment circuitry and option cards.
