Like our PCI-based TDM800P, the AEX800 provides an industry first with 8 standard two-wire, RJ-11 interfaces on a single card bracket. This eliminates the need for multiple brackets, external dongles, or splitters. In doing so, the AEX800 reduces part complexity, cable clutter, and points of failure.
The AEX800 contains two module banks. Each bank supports up to four
analog interfaces and may be filled either with one standard Digium®
quad station (S400M) or line/trunk (X400M) analog module, or up to two
standard Digium single analog station (S110M) or line/trunk (X100M)
modules, enabling the creation of any combination of ports.
The
optional VPMADT032 hardware echo cancellation module provides 1024 taps
(128 milliseconds) of echo cancellation for superior echo cancellation
on both types of analog interfaces. If the hardware echo cancellation
module is not installed, the AEX800 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 SMB or SOHO telephony environments capable of satisfying the
needs of small or medium business applications at an industry-leading
price.
