The Digium Wildcard
TDM850B is a half-length PCI 2.2-compliant 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.
The TDM850B provides an industry first with 8
standard two-wire, RJ-11 interfaces on a single PCI bracket. This
eliminates the need for many pieces of equipment. In doing so, the
TDM850B reduces part complexity.
The TDM850B 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 TDM850B may be used in conjunction with
Digium's High Performance Echo Canceller (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
