Abstract

PURPOSE:To economize a common line signal controller by providing plural network controllers to a line controller, providing a common share memory for relaying a signal of the network controllers and connecting an exchange processing processor group and the network control group with a bus. CONSTITUTION:In case of signal unit reception, the signal unit is subjected to error correction and retransmission request processing by a CSE (line controller) 11 and give to a normal signal unit CSPI (network controller) 104. The CSP uses information included in the signal unit to reference a CM (common memory) 106 thereby transmitting the signal unit to a CP (exchange processing processor) 108 in which the corresponding talking line is accommodated via a bus 106. In case of transmission processing, the call control information from the CP 108 is fed to the CSI 104 as the signal unit. The CP 108 and the CPS 104 are set in response to the traffic in advance. A destination CSE 102 decides the unit according to a routine table of the CM 106 and the unit is stored in a transmission buffer provided in correspondence to the CSE in the CM 106.
