| BT TSX50
(Mitel SX50) Telephone System |
The TSX50 is an integrated communications system which uses an innovative
modular design. Up to 10 peripheral circuit cards can be plugged in or taken out
without upsetting the system. This allows easy system expansion, fault finding
and card replacement. The TSX50 is a compact digital electronic system using
stored program control and advanced digital architecture.
The TSX 50 can simultaneously use tone, pulse dial or TX14
feature phones. It can cater for up to 160 extensions, 32 exchange lines
(trunks), 24 private circuits and has its own console. It has features such as
call information logging, automatic route selection, extension metering, direct
inward access, direct outward dialling, emergency switching, pick-up groups,
baby monitoring, and remote access.
 The
TSX50 was first launched in June 1986 with the version UK1 which had G3543/02
software. In July 1989 the UK2 version was released with G3543/03 software. The
final version UK3 was released in April 1990 with G3546/01 software. See the
table below which explains the differences. The TSX50 had two types of power
supply. Earlier versions had the 1A power supply fitted which had an output of
140W, whilst later versions had the higher rated 2A with an output of 225W. See
below for the maximum capacity for each type.
