MAINTENANCE PROCEDURE
“13-B”: CCH C-Level Infinite Loop Failure. (Permanent)
(1)Meaning
The system message “13-B” indicates that C-level infinite loop (Note) of the PM (Port Microprocessor) within the CCH/CCT circuit card has occurred more than 15 times within an hour. When this fault has occurred, the specific PM is placed into make-busy state and restarted. (The fault counter is “0” at the beginning of every one hour.)
Note: This is a state in which the C-Level Monitor Program (the program which detects off-hook/on-hook related to lines/trunks) repeats a specific routine. The number of times to be repeated is counted by the error- counter corresponding to the CPU.
(2)Related System Message
When the C-level infinite loop failure occurs less than 16 times, the Phase 1 restart or Phase 3 restart is exe- cuted at the specific PM of CCH/CCT card and the system message “13-C” is output.
