Looking for Technical Support for the Digium TC400B Transcoder Card - 96 Channels?

Product Description
  • Digium TC400B is a bundle of the half-length, low-profile PCI-2.2 compliant TC400P base card and the TC400M voice processing module.
  • Designed to handle, in dedicated DSP resources, complex codec translations for highly compressed audio as would otherwise be processed by Asterisk in software. (Asterisk, in software and with Digium G.729a licensing, is capable of transforming the G.729a codec into other codecs for the purposes of call origination or termination, bridging disparate calls, or VoIP to TDM connectivity.)(These transformations in software are very expensive, in terms of MIPS, and require a substantial amount of CPU time to accomplish.)
  • TC400B not only relieves the CPU of this duty, freeing it up to handle other tasks or to complete additional call processing; but also provides Asterisk with the capability of bridging G.723.1 compressed audio into other formats, a capability not previously possible.
  • TC400B decompresses G.729a (8.0kbit) or G.723.1 (5.3kbit) into u-law or a-law; or, compresses u-law or a-law into G.729a (8.0kbit) or G.723.1 (5.3kbit).
  • Rated to handle up to 96 bi-directional G.729a transformations or 92 bi-directional G.723.1 transformations.
  • C400B does not require additional licensing fees for the use of these codecs nor does it require the registration process associated with Digium's software-based G.729a codec licensing.
  • Services and Features:
  • 96 Bi-Directional G.729a
  • 92 Bi-Directional G723.1 (5.3kbit)
  • U-Law
  • A-Law
