Abstract

PURPOSE:To obtain the economical and simple outgoing register trunk circuit, by providing the function for DP and PB signals with the outgoing register trunk of exclusive use. CONSTITUTION:When the subscriber SUB hooks up the handset, the presence of call is known from the scanner SCN with the periodic operation of the central controller CC. Based on the information selected, the central controller CC transmits the link close instruction to the switch controller SC. Further, at link connection, taking into consideration the signal reception preparatory time of both the outgoing register trunks of DP outgoing register trunk DPORT and PB transmission register trunk PBOPT, the link connection between the subscriber SUB and multiplex terminal line MCT is made final connection. Further, the signal outgoing register trunk which is made unnecessary with the signal system transmitted from the subscriber SUB is compulsively cut off.
