Tmonitor™ TM3000


The TelcoBridges Tmonitor™ TM3000 is a high-performance network monitoring solution for GSM wireless and wireline networks that enables service providers to perform a quality of service (QoS) analysis of their network, meet their lawful intercept and E911 or E112 obligations, and enable new value-added offerings, such as real-time location-based services (LBS).

Adding the TM3000 to your network is like a permanent intelligence upgrade for your network operations. Unlike network probe hardware, the Tmonitor TM3000 does not affect the status of a call or introduce unwanted data artifacts, making it the ideal platform for QoS activities, lawful intercept, and real-time LBS. Unlike a software-based solution, the TM3000 does not negatively impact the overall performance of the network. Finally, the TM3000 is designed to work seamlessly across networks comprised of hardware from multiple telecom equipment manufacturers, capturing all relevant and required data and providing a truly complete picture of the network’s operations and the location and status of subscribers, in support of E911, E112 and other real-time LBS efforts.

Each Tmonitor TM3000 unit can perform non-intrusive, full-duplex monitoring and filtering of OC3/STM-1 links at line-rate, providing up to 100% packet capture. Data captured by the TM3000 is routed via TCP/IP to an application server where it can be analyzed and acted upon.


Features and Benefits

Monitoring applications. In addition to recording and analyzing voice traffic, and generating and verifying call detail records, the TM3000 allows service providers to perform fraud detection, engage in lawful intercept, support E911 and E112 requirements, and enable location-based billing. The TM3000 also enables service providers to offer new valued-added location-based services, including proximity-based notification, real-time vehicle traffic reports, and the ability to alert roaming customers by SMS.

Carrier-grade performance. The Tmonitor TM3000 is TelcoBridges’ highest capacity monitoring solution. Multiple TM3000 devices and application servers can be clustered together in one or more facilities to provide essentially unlimited scalability.

Network monitoring flexibility. The Tmonitor TM3000 allows service providers to process and analyze all data captured in SS7, ISDN and HDLC packets and raw OC3 / STM-1 traffic. It features highly configurable on-board packet filters so that only relevant information is captured from traffic streams and stored.

Non-intrusive. In order to maintain overall system performance and QoS, the TM3000 does not introduce latency or otherwise modify or alter the stream of communications. The TM3000 fully supports multi-vendor network architectures and requires no modification to existing communications equipment.

The TelcoBridges Tmonitor TM3000 is the leading carrier-grade solution for service providers looking to monitor, analyze and optimize their network performance while laying the groundwork for new offerings like real-time LBS. For more information, visit
