Tmedia™ TM3000 Network Monitor


Telcobridges TM3000 - Tmonitor

The TelcoBridges Tmonitor TM3000 is a high-performance high-capacity voice and data traffic monitoring solution for OC3/STM-1 connections that enables service providers to record and analyze signaling records and voice traffic, 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 TM3000 unit can perform non-intrusive, full-duplex monitoring and filtering of two OC3 or STM-1 interfaces per device at line-rate, providing up to 100% packet capture. Data captured by the TM3000 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 the onboard IVR capabilities and TB StreamListen™, a utility application supplied by TelcoBridges.

Unlike a network-monitoring probe, the Tmonitor TM3000 does not affect the performance of the network or the status of a call or introduce unwanted data artifacts. 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 and other real-time LBS efforts.
TelcoBridges also offers the Tmonitor TM1000 for T1/E1/J1 connections.


Features and Benefits

Monitoring applications. The Tmonitor TM3000 allows system integrators to build systems to record and analyze voice messages, generate and verify call detail records (CDR) and many others. It also allows services providers to perform fraud detection, lawful interception, and location-based billing.

Carrier-grade performance. The Tmonitor TM3000 is a high volume monitoring solution, with voice recording capacity, while meeting the capacity challenges of OC3/STM-1 connectivity. Multiple TM3000 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 TM3000 allows service providers to process and analyze all data captured in SS7, ISDN and HDLC packets and raw OC3/STM-1 traffic, as well as record up to 512 simultaneous channels of voice traffic. It features highly configurable on-board packet filters so that only relevant information is captured from traffic streams and stored by the system application.

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 TM3000 also features ZeroLinkDown functionality, enabling full system maintenance, including device replacement, without interrupting the communications network.
