Centralized Network Surveillance System for IP, Wireless, and TDM Networks

Gaithersburg, Maryland, USA - Jul 08, 2021 - GL Communications Inc., a global leader in telecom test and measurement solutions, addressed the press regarding their high-density web-based network monitoring and surveillance system (NetSurveyorWeb™) for IP, Wireless, and TDM Networks.

NetSurveyorWeb Architecture

“GL’s 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.

“Typically, the surveillance system requires TDM, and IP protocol analysis probes deployed at various physical locations. These probes capture, decode, and segregate the traffic to calls and forwards the CDRs, signaling frame details, and other statistics to the centralized database server”.

He further added, “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. For customers with low storage requirements, GL offers NetSurveyorWeb™ Lite, which can be deployed on the same system as the network monitoring probes and offers historical data retention up to 9 GB”.
