MAINTENANCE PROCEDURE
2.2 Technical Terms for Explaining Message Detail Data
Some technical terms are used to explain the detail data in each system message and circuit card information. Some technical terms and the circuit card mounting information, which are used in common to explain the various system message, are shown below.
Phase 1 Restart Processing Execution
All the processing being executed is suspended, and the system operations are allowed to restart from the monitor program without any hardware controlling involved. More specifically, the processing on calls being handled by the programs are abandoned, and all the connections already established are maintained.
Phase 3 Restart Processing Execution
By initializing each PM (Line/Trunk circuit card), the following processes are executed:
•Forcibly releasing the calls connected with the initialized Lines/Trunks.
•Releasing the related links.
Data for Analysis by NEC Engineers
These message detail data are used by NEC engineers when analyzing faults, and thus they are not used in ordinary fault repair works.
When a fault is complicated one, the data are used when reporting the fault to NEC or when NEC engineers inquire about the fault.
