Abstract

PURPOSE:To guarantee minimum service to many subscribers even under traffic conditions in failure, by making connection to the incoming calls to the incoming trunks having the means compulsively cutting-off the calls without restriction, and cutting off them in a given call time. CONSTITUTION:If incoming calls are given from special lines, starting is made to a translator TLR as well as conventional lines. The TLR outputs the information so that the connection is made to the outgoing trunk OGT by neglecting the instruction of the restricting device RCIE, if the information of special incoming trunk ICT is present, then the marker MKR connects the incoming trunk ICT with the outgoing trunk OGT. The incoming trunk makes the monitor for call time, and if it reaches a given time, the call is compulsively cut off to release the outgoing trunk OGT.
