Title: Traffic handling system for PBX - has selection-end signal made time-independent of free and busy signals
Inventor: JAEGER HORST
IPC: H04Q3/62
Filed: 1980-02-07
Abstract: The system uses a selection end signal consisting of the first pulse and another fourth pulse of equal size following this pulse. Any re-selection after the first pulse has been sent causes a delayed transfer of the fourth pulse. The delay lasts a given time after the end of the re-selection signal has been recognised. The interval between the last pulse in the re-selection signal and the fourth pulse is longer than the interval between the second and third pulses and shorter than an intermediate selection time. The end-of-selection signal is thereby independent of the subscriber free or subscriber busy signals even when the start of the end-of-selection signal coincides with re-selection in the opposite direction.
