Analogue Keysystem, made by Siemens (distributed in the UK by Norton Telecoms) with an
ultimate capacity of 8+24. NTX 10 keysets (Masterset
113 or Saturn 200), the brown keyphone above, were originally
supplied but these were soon replaced by Keysets 1,2 & 3.
The system comprised of a Control board at the front of the unit and had three peripheral card
slots located behind it. The first has to be a 4+8 card, whilst the
second could be a 0+8 or a 4+8. The third slot can only support a 0+8 card. The MDF is
self contained within the system case and the system can be programmed by the use of a Keyset 3 or by a
keyset that is fitted adjacent to the system, as an LCD
display shows through a window in the system cover.
The first extension port also appears on an Australian style plug that is fitted behind
and at the bottom of the chassis.
The Keyset 1 has 8 configurable buttons whilst the Keyset 2 had 16 buttons. Keyset 3 is
similar to the Keyset 2 except it also has a display.
The system is programmable for MF & LD lines and has integral music on hold (the tunes
were diabolical). Simple call logging could be obtained with the additional V24
card which was fitted to the control board.
POTS could only be used if a TWIM card is fitted on an extension card.
