GL introduces centralized network surveillance system for IP, wireless and TDM networks

28 September 2021

Telecom test and measurement company GL Communications Inc. has introduced its high-density web-based network monitoring and surveillance system for IP, wireless and time-division multiplexing (TDM) networks, called NetSurveyorWeb.

“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.

The central system contains a database engine, a web server and web-based application NetSurveyorWeb to facilitate data storage and retrieval through web browser clients. NetSurveyorWeb supports various decode standards like ANSI, ITU, ETSI and 3GPP for all the supported protocols. It can identify and analyze CDRs using key performance indicators (KPIs). Complete CDRs also include support of end-to-end multi-interface call flow and display of real-time data signaling, traffic and quality of service (QoS) performance metrics.

The application can search and filter calls of interest with customized filtering and search options and apply single or complex filters for data analysis.

KPIs include:

  • Packet loss, gap, jitter, delay, RTP performance statistics, R-factor and MOS scores, and unparalleled voice band statistics
  • Signaling performance (signal level, noise level, and echo)
  • Delay measurements (RTD, OWD)
  • Signaling messages and traffic types, successful and unsuccessful failure causes
