Selling lead description:


The Passive GSM Interception System of GSM Monitoring is intended for search, interception and registration of cellular signals on standards GSM-900/1800 in stationary or in mobile variant. SCL-5020 multi-channel tunable Passive GSM Interception System. Each receiver is independently tunable to any BTS of the GSM Network. GSM Monitoring system is intended to ensure interception and deciphering of voice conversation from standards GSM-850/900/1800/1900 Cellular network in stationary or in mobile environment.Passive GSM Interception System also intercepts registration and service channel information from the cellular network. Features and Specifications: On line monitoring up to 16 duplex GSM channels, Interception Monitoring and logging of GSM-850/900/1800/1900 communication standards in stationary or in mobile variant. Several SCL-5020 systems can be configured in a LAN environment to provide a near-exact physical location of the target and to form a Central Monitoring Station. Auto detects, decoding and recording of telephone conversations, network information in the system to the digital media (magnetic / optical). Automatic tuning of the system, with a possibility of scanning and recognition of control channels and communication system parameters. Target selection by different parameters: IMEI, IMSI, TMSI, MODEL, REVERSE MODE, RANDOM SCAN MODE, TARGET DISTANCE FROM THE BASE STATION, TYPE OF SUBSCRIBER HANDSET, TAGET DIALLED & RECEIVED NUMBER (PLMN). Scanning of GSM network parameters in the controlled area (Service Provider, Broadcast Channel No., LAC, Cell IDs, Signal Levels). Interception and Monitoring of Short Message Service (SMS) traffic. Monitoring of both forward and reverse channels (duplex conversation). Showing and recording to the magnetic media all network protocols of telephone conversations and other events in an inspected zone of a communication system with sorting by numbers and dates, file type etc. Direction Finding Equipment can be integrated with a digital map of the location into the System. Receivers management with neighboring cell details for network handover information. Switching on / off the recording of conversations, short text messages, data transfer, network information and other parameters. For price and other detail please send us E-mail

The system Integrated Passive GSM Monitoring System through  BTS/BSC Link Surveillance provides total traffic monitoring of  the target BTS/BSC Link. These Links generally communicate     using E1/E2/E3 Microwave links depending on the network design and implementation.

The system comes in a Transportable chassis where all the modules are seamlessly integrated to provide an Integrated Monitoring and surveillance platform to the operator for effective and efficient Interception process.

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 comes along with a GSM Protocol Analyzer, which is an effective and easy-to-use PC-based protocol analyzer for  real-time monitoring and analysis of GSM, SS7, GPRS, EDGE     and GSM-R networks. 

 It is a powerful tool for protocol monitoring and call and session analysis for both network element manufacturers and mobile operators.

The System is capable of analyzing in real-time a wide set of 2G/2.5G protocols at multiple network interfaces simultaneously. 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 Analyser incorporated in the system has a wide support for manufacturer-specific protocols. For Nokia, Ericsson, Nortel and Siemens GSM, GPRS and EDGE 
    protocols are fully supported. Lucent is supported for GSM and  GPRS protocols; Motorola and Alcatel also for GSM protocols.

The System's SS7 Analyser is capable of analyzing in real-time protocols at the SS7 MAP (C, D, E, F, G, Gc, Gd, Gf, Gr, Lc, Lg,  Lh), TUP (PSTN), ISUP (PSTN, Nc), INAP, CAP, SigTran and HSL     interfaces. 

The Analyser supports the Chinese, Australian, UK, Russian, French and Finnish country-specific variants of ISUP as well as  ANSI specification.
