At TMC’s winter IT Expo in Ft. Lauderdale, Florida Digium introduced several new products to the public for the first time. These included the long awaited TC400B, the TDM800P, the TE120P and a new software based High Performance Echo Canceler (HPEC).

The TC400B (featured in the image at the left) is designed to handle the complex codec translation of highly compressed audio in dedicated DSP resources on the card. Such translation would otherwise be handled with Asterisk in software putting a burden on the host CPU.

The TDM800P is the 8-port card closely related to the TDM2400P with a few distinct differences. The TDM800P can support up to four of the single-port analog modules used with the TDM400P OR up to two of the quad-port modules used with the TDM2400P. All 8 ports on the TDM800P may be connected to RJ-11 interfaces directly on the card.

The TE120P is the new single-span T1/E1/J1 card and also uses VoiceBus technology for better interoperability with different PC systems. This product will replace the TE110P over the next 6 months.

The High Performance Echo Canceler (HPEC) is a host-based, Toll-Quality, echo cancellation software suite designed to operate under 32-bit and 64-bit Linux. It provides echo cancellation with configurable tail lengths of 16ms (128 taps), 32ms (256 taps), 64ms (512 taps), and 128ms (1024 taps) on a per channel basis. This new software echo canceler is a step above existing software echo solutions on Asterisk and requires only a moderate amount of CPU time in order to effectively eliminate echo. The HPEC will support up to 24 channels with Digium hardware as tested on a 3GHz dual-core CPU based system. The HPEC software will be free with Digium cards and priced at $10 per port for use with non-Digium hardware.
