Tmonitor™ TM1000


The TelcoBridges Tmonitor TM1000 is a high-performance voice and data traffic monitoring solution that enables service providers to record and analyze messages, as well as optimize network performance and quality of service (QoS), while providing a foundation for new value-added offerings, such as location-based services (LBS).

Each Tmonitor TM1000 unit can perform non-intrusive, full-duplex monitoring and filtering of 64 T1/E1/JI interfaces per device, providing up to 100% packet capture. Data captured by the TM1000 is then routed by TCP/IP to an application server where it can be analyzed and acted upon. In addition, PCM voice traffic can be recorded with TB StreamServer™, a utility application supplied by TelcoBridges.

Unlike a network-monitoring probe, the Tmonitor TM1000 does not affect the performance of the network or the status of a call, or introduce unwanted data artefacts. For cases where it is located immediately next to the network to be monitored, the TM1000 is designed to work with a purpose-built 32-port Monitoring Patch Panel that features a high-impedance circuit to limit signal drain. For longer distances, TelcoBridges has designed an optional 16-port isolation patch panel, used in conjunction with the monitoring patch panel, which helps to maintain high-impedance resistance in the path to the monitoring equipment.

Features and Benefits

Monitoring applications. In addition to recording and analyzing voice messages, generating and verifying call detail records (CDR), the TM1000 allows service providers to perform fraud detection, lawful interception, and location-based billing. The TM1000 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 TM1000 is a high volume monitoring solution. Multiple TM1000 devices and application servers can be clustered together in one or more facilities to provide essentially unlimited scalability. Application servers can also be deployed remotely for fully distributed monitoring.

Network monitoring flexibility. The Tmonitor TM1000 allows service providers to process and analyze all data captured in SS7, ISDN and HDLC packets and raw T1/E1/J1 traffic, as well as record specified voice 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 Quality of Service (QoS), the TM1000 does not introduce latency or otherwise modify or alter the stream of communications. Installation of the TM1000 requires no modification to existing communications equipment.
