Подскажите, в какой доке посмотреть описание сообщений D-канала типа:

DCH: 15 EST TIMER REC TIME: 17:40:34 13/05/2008

DCH: 15 EST REMOTE TIME: 17:40:48 13/05/2008

Книга 553-3001-411 "Software Input/Output Guide System Messages".

Глава "DCH: D-channel Diagnostic (LD 96)".

"TIMER REC = Reestablished a D-channel due to timer recovery."

"REMOTE = Release or re-establish was initiated by the far-end. No action required, problem is at the far-end."
