method for error checking and evaluation reports of members of a operatorservice and furnished office

摘要

The message fault detection and evaluation method has a counter (Z1) indexed each time a message fault for a data link connection to a subscriber (OPE) is detected, with the subscriber logged when the counter reaches a given count, a fault indicated when the subscriber is logged a given number of times within a defined time interval. Each time the subscriber is logged a second counter (Z2) may be indexed, with a fault indication supplied to an operation and maintenance service (OMS) when the second counter reaches a given count value within the defined time interval.
