Solutions

GL provides a distributed network surveillance system with protocol analysis probes deployed at various physical locations. GL’s high density protocol analyzer, PacketScan™ HD, can capture and process high volumes of phone calls over many communication protocols.

The protocol analyzer probe works with NetSurveyorWeb™, a centralized web-based monitoring system for a comprehensive view of network performance. It features rich graphics, real-time and historical storage of call detail records, and allows the operator to build custom key performance indicators. It also allows the operator to filter on calls of interest and set up automatic alerts.

PacketScan™ HD for IP and Wireless Monitoring is a high density 2U Rack mounted Network Appliance (4 x 1GigE, 2 x 1/10GigE, 2 x 40/100GigE). Almost all VoIP (SIP, MEGACO, MGCP, H.323, SCCP) and Wireless protocols (IMS, 4G LTE, UMTS IuCS, GSM A, CAMEL, BICC, ISUP, MAP, Gb, and GTP) over IP transport layer can be captured and decoded. The robust traffic filter feature within PacketScan™ HD application permits the user to filter on traffic of interest.

NetSurveyorWeb™ - Network Surveillance System

NetsurveyorWeb™ is an integrated and simplified web-based monitoring system that collects information from PacketScan™ probes and stores it in a database. It is a convenient solution for monitoring a large geographically dispersed network from a centralized location. It is a browser-based application that allows an operator to listen to phone calls, view call detail records and produce graphs on statistics of interest. Operators can remotely log into the system for convenient access.
