Abstract

PURPOSE:To omit the wiring exclusive for the signal and thus to reduce the number of the wiring between frames for the time division exchange by carrying out the signal control via the main link. CONSTITUTION:The control signal which is transmitted from signal control unit SPR to trunk device ATRK and DTRK plus subscriber line concentrator LC is classified previously into the cyclic signal which is required to transmit and renew the state to be secured in a fixed period and the random signal whose state alteration request is produced at random. And the transmission time region for both the cyclic and random signals is divided to transmit both signals via one signal time slot.
