Patent DE-4242463-A1 (DE)
Title: Operating procedure for telecommunications terminal units
Inventor: BRAUN DIETMAR
IPC: H04M9/02
Filed: 1992-12-16
Abstract: The operating procedure is used for a number of terminal units with their interfaces connected in series to a common line. Each interface is addressed by the exchange (Zst) with further control lines allowing standardised simple control procedures for a standard interface.The terminal appts. (EE1...EEN) are coupled to respective connection modules (AM1...AMN) associated with a common connection (GA). The address received from the exchange is evaluated at the first connections module (AM1) which forwards it to the next module when it is not recognised, the transmission line to the exchange being automatically switched across. When the address is recognised the control line is engaged, while being blocked for each other module. A final module allows information transmitted as an address to be interpreted directly as a switching command.
