PURPOSE:To avoid the reduction in the network capacity accompanied with double connection at outgiong control with parallel monitor system, without requiring the high speed gating or the extension of sampling period, by extending and separating the line memory. CONSTITUTION:The subscriber (SUB) terminals and the main line trunk(COT) terminals are connected by allocating them to a pair of time sharing channels of i and i+80 having the fixed phase difference for the 80 time slots by the delay line(DL) on the highway(HW), and further, the double connection for parallel monitor is realized, by allocating the subscriber (SUB) terminals and the PB reception trunk (PBORT) terminals to a pair of time sharing channels of i and i+80. In this case, the line memory is extended, and the PB reception trunk terminal C is allocated to the extended line memory LM2. |
