Abstract

PURPOSE:To eliminate the need to equip a time-division line concentrator with an independent a collecting-distributing mechanism which collects and disctributes supervision control signals, by providing a circuit-corresponding part and channel assignment memory. CONSTITUTION:A circuit number in line-concentration control memory 15 is decoded by decoder 14 and the corresponding circuit-corresponding part is supplied with a circuit-assignment enagle signal. Now, when circuit number #n is supposed to be written in the m-th address, the m-th time slot attains the transfer of digital sound data between highways 18-1 and 18-2. The Ti-th time slot is assigned as a control channel which transmits and receives the supervision control signal of the circuit. Signal processor 17 transmits a control signal onto a down highway 18-2 and then fetches a status supervisory signal and dial signal on an up highway.
