Siemens T-1000
Desktop full-page teletypewriter - this page is a stub

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 also as the base of several cipher machines.

Configurations
APE-25
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
APE-26
The APR-26 configuration consists of the following modules:

  • STT21/A100
  • BET?
  • LAT30/A100
  • SST?
