GL Communications Inc. announced today the release of a new application Call Data Record – an ultimate diagnostic tool for telecom networks. Addressing a press conference Mr. Vijay Kulkarni, CEO of the company said, “CDR provides comprehensive information on each and every call occurring on T1 E1 lines, including: voice capture for both directions, complete signaling information for each direction for CAS, ISDN, MFC-R2, SS7, all alarms and errors occurring during the call including BPV, Frame Errors, CRC errors, Loss Of Sync, and more”.

He added, “The application works with CCA (Call Capture and Analysis) and VBA (Voice Band Analyzer) applications and generates the two types of reports: Call Summary Report, Call Detail Report”.

Mr. Kulkarni further added, “The Call Capture & Analysis (CC&A) application captures bidirectional voice traffic to files. Captures may be triggered by protocols such as signaling bits, ISDN or SS7 signaling. CCA also records signaling and alarm events, as well as producing a summary record for each call. Each CCA instance can monitor a single T1 or E1 trunk. Multiple CCA instances may be run concurrently to monitor multiple trunks.

The Voiceband Analyzer (VBA) application operates in near-real-time, processing the signal files recorded by CCA. VBA may be configured to detect in-band events such as sporadic acoustic echo, line echo, digit tones, in-band impairments, and the like. It also produces summary measurements of the captured signals, including active speech levels, noise level, percent time active, and DC offset. VBA records its output into two files, the first containing overall channel measurements, and the second containing event records”.
