The Sapphire was Mercury compatible 1 + 5 PABX. It could be expanded to a 2 + 8 by
adding a 1 + 3 clip in module.
An FT terminal could also be fitted to this system.
A console must be fitted to the system, as it is impossible to program the system
without it. It also has key & lamp indication of line and extension
status. On a 1+5 system the console is extn 1, whilst on a 2+8 system it becomes
extn 21 (extensions are numbered 1 -5 or 21 - 28).
The system could accommodate either LD or MF phones - even a mixture at the same
extension.
Numbering range:
| 0 | Do Not Disturb (on and off) |
| 1 - 5 | Extension numbers |
| 21 - 28 | Extension numbers |
| 6 | hold/transfer (or R*6 on DTMF) |
| 76 | Plus 1 - 0 = short dial numbers |
| 77 | Prime extension (when used, all external calls are answered at this phone. If extn 1 has been set as prime extension, it cannot be overridden by any other extn) |
| 8 | Answer at a non-ringing extension |
| 9 | Outside line |
The console has buttons for Prime Extension, Volume, Do Not Disturb and Monitor
(on-hook dialling only - no full handsfree)
The console was available in dark grey or light grey, but the CPU was always in
white. The console was attached to the system box by a 2 metre cable with a 32 pin
computer style plug.
