Digium Wildcard TDM800P is a half-length Asterisk PCI 2.2-compliant, 8 port card for connecting analog telephones and analog POTS lines through a PC. It supports combinations of FXS and/or FXO modules for a total of 8 lines. Use the telephony card selector to identify a card that fits your requirements.
The TDM800P, using Digium VoiceBus™ technology, provides an industry first with 8 standard two-wire, RJ-11 interfaces on a single Asterisk PCI bracket.. This eliminates the need for multiple brackets, external dongles, or splitters. In doing so, the TDM800P reduces part complexity, cable clutter, and points of failure.
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 optional hardware echo cancellation module provides 1024 taps (128 milliseconds) of echo cancellation for superior echo cancellation on both FXO and FXS interfaces.
If the hardware echo cancellation module is not installed, the TDM800P may be used in conjunction with Digium's High Performance Echo Cancellation (HPEC) software, 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.
