Centralized network monitoring system

“GL’s network monitoring system can record and playback phone calls and filter interesting calls. The monitoring system can store, retrieve, query, report and display call detail records (CDRs) by non-intrusively connecting to TDM, analog, optical or IP networks. Currently supported protocols include 5G, 4G (LTE, IMS, Diameter), 3G UMTS (IuCS, IuPS), 2G (GSM, TRAU, MAP, CAMEL), VoIP (SIP, ED-137, SIGTRAN, H.323 , MEGACO, MGCP), TDM (SS7, ISDN, CAS, GSM, TRAU) and analog systems.

“This surveillance system requires protocol analysis probes deployed at various physical locations. These probes capture, decode and aggregate traffic into calls and transmit CDRs, signaling frame details and other statistics to the centralized database server. These probes can capture data at high speed, store it locally and include protocol analysis software for easy analysis in the field as well,” said Vijay Kulkarni, CEO of GL Communications.

He further added, “The core system includes a database engine, a web server and NetSurveyorWeb™, a web application, to facilitate data storage and retrieval through web browser clients. For customers with low storage requirements, GL offers NetSurveyorWeb™ Lite, which can be deployed on the same system as network monitoring probes and offers historical data retention of up to 9 GB.”
