GSM Backhaul Monitoring Systems
Deployment of the system in Shelter

GSM Backhaul Decoding and logging system carries out BTS/BSC Link Surveillance providing total traffic monitoring of the target BTS/BSC Links which are generally E1/E2/E3 microwave links depending on the network design and implementation. The system is an intelligent data acquisition tool with effective data pre-processing capabilities for capturing the network data in the GSM, GPRS, EDGE networks. The system has been designed in a manner to provide and capture both the uplink and downlink data in the Abis interface.

The system can monitor Abis, A and Gb over Frame Relay/IP interfaces and at core network SS7 (C, D, E, F, G, Gc, Gd, Gf, Gr), High Speed Signaling Link (HSL), SigTran, PSTN, Ga, Gi, Gn, Gp and Gs as well as Location Services (LCS) interfaces. The GSM Analyzer incorporated in the system has a wide support for manufacturer-specific protocols including Nokia, Ericsson, Nortel and Siemens 4 GSM, GPRS and EDGE protocols. Lucent is supported for GSM and GPRS protocols; Motorola and Alcatel also for GSM protocols.


  • Passive Collection, Analysis and Logging Infrastructure for GSM Backhaul interception
  • Total Traffic Monitoring of Target BTS in the form of Voice/SMS/IP packets (Http, E-mail etc)
  • Signaling of Individual target can be filtered according to IMSI/IMEI/TMSI/P-TMSI Calling Number or Mobile Station's IP address
  • The system supports proprietary Switch manufacturers (Nokia/Siemens/Ericsson/Alcatel/Lucent/Nortel/Motorola) protocols
  • The software has capability to monitor Gb Interface along with the associated deciphering tool for GEA Algorithm
  • The systems Analyzer can simultaneously connected to minimum 8 Bi-Directional E1's
