Patent DE-2532920-A1 (DE)
Inventor: JAEGER HORST
IPC: H04Q3/62
Filed: 1975-07-23
Abstract: This switching signal system with primary and secondary signals (HK, NK) ensures that a connection cleardown initiated by a calling telephone station and by a called telephone station irrespective of the direction of the connection set-up and the connection cleardown result in different signalling sequences permanently allocated to the respective ends of the connecting line. This ensures in simple fashion that in each case a new seizure of the corresponding transmission circuits takes place only at the end of the period required by the monitoring devices. AC and audio-frequency signals are used as the signals. The method is particularly suitable for connection traffic between primary and secondary systems (HA, WUA). <IMAGE>
