Digital line multiplexer
- this page is a stub
DELTAMUX was a multiplexer for military
telephone lines
conforming to the EUROCOM standard, developed around 1978 by
Philips Telecommunicatie Instrustrie (PTI)
in Hilversum (Netherlands).
It allows 16, 32 or 64 individual 2-wire subscriber lines,
each with a data rate of 16 or 32 Kb/s,
to be multiplexed into a 256, 512 ot 1025 kbit/s stream
that can be carried to an exchange.
|
The unit was used to connect a local network of wired (field) lines
– typically organised around a communications vehicle – to a remote
exchange, by means of Line Of Sight (LOS) radio, or by wire.
It could also be used as a hub between switches.
DELTAMUX was used by the Dutch Department of Defence, as well as by
some other countries, including Greece. The device shown here was
manufactured by PTI as part of the ZODIAC
integrated communications system – developed by
Holland Signaal –
and was often used in combination with a
MUCOLEX data encryptor.
