Centralized Network Surveillance System
“GL’s Network Surveillance System can record and playback phone calls and filter on calls of interest. The surveillance 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 group the traffic into calls and forwards the CDRs, signaling frame details, and other statistics to the centralized database server. These probes can capture data at high speed, store 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 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.”
