MAINTENANCE METHOD

摘要

The method operates and supervises common channel signalling No.7 system effectively. The CCS No.7 system includes an IOIP (1) for displaying processed result on a terminal, a SAIP (2) for processing alarm signals, a DKIP (4) for controlling a disk, a DTLP (6) for supervising operating functions of an exchange a SMP (7) for initializing and reconstructing a CPU, a SPB (8) for executing a level 3 function, and a CSIOB (9) for communicating between terminals and the DTLP (6). The method comprises the steps: (A) initializing a system when an initializing signal is received; (B) initializing process data when re-initializing signal is received during block operations; (C) processing signal network change request; and (D) processing alarm signals and test requests.
