POINT CODE INCREASE/DECREASE PROCESSING SYSTEM FOR SIGNAL CONNECTION CONTROL PART OF NO.7 COMMON LINE SIGNAL SYSTEM

摘要

PURPOSE: To deal with the increase/decrease of point codes on a line and to secure the coincidence of point code states among NO.7 signal link control processors in a multiprocessor type system which includes those NO.7 signal link control processors having the signal connection control parts of a NO.7 common line signal system and a common control processor which controls the NO.7 signal link control processors. ;CONSTITUTION: The system data show whether point codes are prepared or not. Then the contents of the system data are compared with the contents of the station data so that the increase/decrease of the point codes are decided. A signal connection control part 4 of a common control processor 1 inquires a message transfer part 6 about the states of the increased point codes and informs the NO.7 signal link control processors 2 and 3 of the result of inquiry.;COPYRIGHT: (C)1993,JPO&Japio
