Digital Recording Board
  • Passively Tap Digital Extensions For Call Recording APP

  • Half-Length Cards with Modular 8/16/24 Channels

  • Dedicated DSPs for Decoding/Encoding, Start/Stop Modes

The DST is all-in-one resources with modular structure for logging and monitoring behind PBXs and fits into a variety of PBXs extension tapping environments.

The DST range of single-slot solutions for logging and monitoring behind PBXs, fits into a variety of PBXs extension tapping environments, including connection between the PBX and the proprietary handsets providing passive monitoring of the voice conversation and D-channel (call control). A variety of telephony events such as call taken and key pressed are automatically decoded and sent to recording applications for a powerful set of functions and high integration with PBXs. As a modular structure, the DST series can be customized to provide 24, 16, 12, 8, 4 ports (per slot) ideal small offices up to large call centers. For that reason many developers worldwide depend on DTP series to create robust and high capacity systems in central office and Telco environments.

Solidly built on Synway’s robust FPGA technology, the DST series help logging application providers deliver the most competitive recording solutions with its high performance specifications and the lowest price points when compared with other competitor products. DST series also provide a powerful range of voice processing capabilities via rich dedicated DSP resources to process high-ratio audio compression formats, including license-free G.729 and GSM. This robust architecture further releases host processors from overloading and assures efficient data storage and high reliability for data transmission in the most difficult situations.

The DST series can protect system performance and robustness with its capability to remotely log media stream. Doing this helps solution providers simplify remote debugging or other diagnostic activities and assure high availability of a running system. In addition, Synway’s engineers can remotely monitor applications for users to help optimize systems architecture. An intelligent tool, the DST series is able to adjust to a variety of complex environments by automatically and manually configuring variable parameters, and is widely in service in large-scale call centers.
