A 8+16 max, POT or Featurephone (software dependant), LD/MF analogue switch made by MITEL and only marketed by BT. Known as the Viceroy in the UK or
the Mitel Super 10 in North America. All the cards are contained within the console and the PSU/TJF is fixed to a nearby wall
(console & PSU shown to right). Initial software release was 242 but call logging,
superset working (first 8 ports) and abbreviated dial was made available on latter 243
versions.
Similar in programming, alarms and hardware to the SX10/SX10E.
CONFIGURATION
Power consumption 100 watts
Max capacity:-
8 Exchange lines (4 of which can be AC15 or DC5), 16 Extensions, 8 Intercom paths.
Power fail for lines 1 & 2 only to ports 01 and 02.
Approved for Loop Disconnect exchange signalling only, but will send MF on 243 variants.
Featurephones (Superset 4 or TX14 can only be used on 243 variant).

Before use, the Viceroy system must be loaded with default data. This operation
clears out the RAM and loads default data, ensuring that the database is free from
corruption.

Voltage Test Points
There is a strip of pins located near the DIP switches. System voltages can be tested at this point with a high impedance multimeter.
Pin 1 is the top pin and pin 6 is the bottom pin.

KNOWN PROBLEMS 1. Flat RAM battery. Causes strange problems - usually after a power cut. Corrupts system memory, causes near stoppage - but not quite! Check battery voltages and replace - usually last at least 7 years. 2. Console handset cuts off calls. Old style consoles were prone to the handset socket breaking - test by wriggling plug. Also handset cord fails where it meets the handset. 3. Console goes into night service automatically. Usually caused by console handset cord failure.
