Centralized Network Surveillance System

GL Communications Inc., a global leader in telecom test and measurement solutions, presents the latest software for high-density web-based network monitoring and surveillance system (NetSurveyorWeb™) for IP, Wireless, and TDM Networks.

“Network Surveillance System can record and playback phone calls and filter on calls of interest. The surveillance system facilitates historical storage, retrieval, querying, centralized reporting, and display of 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 and analog systems”, said Vijay Kulkarni, CEO of GL Communications.

He further added, “Typically, the surveillance system requires various protocol analysis probes deployed at different physical locations. These probes capture and intelligently group the traffic into calls and forwards them to the centralized database server”.

In addition, “The central system comprises of a database engine, web server, and NetSurveyorWeb™, a web-based application, to facilitate data storage and retrieval through web browser clients. GL recently introduced a scaled down application called NetSurveyorWeb™ Lite which is an integrated and a cost-effective monitoring system with both the web server database engine and protocol analyzers deployed on a single system. NetSurveyorWeb™ Lite offers historical data retention up to 9 GB”.
