The TDM800P contains two module banks. Each bank supports up to four analog interfaces. The module banks may be filled either with one standard Digium quad analog module (FXS - S400M, FXO - X400M), or up to two standard Digium single analog modules (FXS- S110M, FXO - X100M) enabling the creation of any combination of ports.

The Digium TDM800P may be used in conjunction with Digium's High Performance Echo Canceler (HPEC), a commercial and toll quality hybrid echo cancellation solution. Digium's HPEC provides 16ms to 128ms of selectable near-end ITU G.168 compliant echo cancellation in software.

Using this card in concert with Digium's Asterisk software, standard PC hardware, and the Linux OS, you can create SME or SOHO telephony environments capable of satisfying the needs of small or medium business applications at an industry-leading price.

The naming convention for the TDM800 bundles is as follows: TDM8 X Y B

"TDM8" denotes that the card is TDM800P, "X" denotes the number of FXS modules, "Y" denotes the number of FXO modules, and "B" indicates that this product is a bundle without Echo Cancellation. "E" indicates that this product is a bundle with Echo Cancellation.

Note: On the TDM800P, one module is equal to 1 or 4 ports. The "X" and "Y" denote modules, NOT ports. This is a general discription see product title for actual item information.
