Abstract

PURPOSE:To execute line or packet exchange service by connecting a packet call multiplexed by a packet multiplexing circuit to a packet exchange through a specific bus and connecting a subscriber's call to the packet exchange through the bus. CONSTITUTION:A subscriber's call 2B+D is identified and separated by a digital circuit DLC based upon a subscriber's signal system using a D channel (CH) and a line exchange call and a packet call are respectively identified and separated respectively in the BCH and DCH. The line exchange call on the BCH is connected to a digital channel TDSW and line exchange connection is executed in each call. In addition, a signal on the DCH or packet data is separated and identified. The DCH packet data are collected every plural DLCs and packet-multiplexed by a packet multiplexing circuit PMX and the multiplexed output integral Dp is connected to a packet exchange PH obtained by half-fixing a digital speaking circuit TDSW and terminated at LADP. On the other hand, a BCH packet call is connected to the PH and terminated at LAPB.
