T-1000 is an electronic full-page desktop teletypewriter,
or telex, developed around 1976 by Siemens
in München (Germany) as the successor to the electromechanical
T-100.
The device was used on the public world-wide TELEX network,
but was also the base of several cipher machines.

Below is the block diagram of the modular T-1000. At the center is the
motherboard (GE) which acts as a central hub for the other modules.

|
Matching Unit APE-25 allows the T-1000 to be connected directly to external
transmission facilities without a local cable, via a 4-wire polar current,
low-level, point-to-point circuit. The send line is fed from an internal source.
The low-level interrface complies with MIL-STD-188C and contains three 2-wire
loops: one for the receive loop, one for the transmit loop and one for the
call loop.
The APE-25 configuration consists of the following modules:
|
- Control module STT10/A101
- Manual communications controls BET4/A102
- Line adapter LAT28/A100
- Protector SST20/A100
|
|
The APR-26 configuration consists of the following modules:
|
- STT21/A100
- BET?
- LAT30/A100
- SST?
