Device for recovering silences by time switching, intended to be used with telephone networks with multifrequency signalling between recorders.

摘要

Device for recovering silence by time switching (TASI) comprising an item of transmission equipment with a first set of telecommunication channels and a means 21 of detecting signals on a second set of telephone communication lines and of allocating each line conveying signals to an available channel of the first set and a means of delaying the detected signals; an item of receiving equipment comprising a means of allocating each channel of the first set which conveys signals to a line of the second set according to the allocation datum received from the item of transmission equipment; an item of equipment for communicating messages between transmission and receiving equipment; an item of equipment for registering the start of a multifrequency signalling between recorders on the second set of lines and an item of equipment for disabling, following this detection, the means of delaying the detected signals. <IMAGE>
