ABSTRACT:
Service observing equipment monitors, detects and makes call records from digital and audio information on an individual call basis. The observation equipment can monitor both a Signalling System Seven (SS #7) and a CCITT #7 in which data packets are transmitted along the high speed data links separated from the telecommunication audio channels. The call record indicates how trouble free and efficiently (or how troubled and inefficiently) individual calls are processed by the telecommunication network. A plurality of separate memory locations are assigned on an individual call basis, for the duration of a given call, to store data received over any of many data links and communication channels relative to that given call. After the call has terminated, the accumulated data is analyzed to determine the call's final disposition. A call record is restored in memory for reports and/or transmitted to a printer or another processor. Then, the emptied memory locations are reassigned to accumulate data relative to new calls. In addition, the service observation equipment can trap annoyance calls and generate disposition reports on threshold levels of operation, provide live observing of calls in progress, generate real-time and/or long term peak and average link occupancy reports, and display a listing of time stamped messages for a specific call in order to provide for protocol analysis.
