PCI)
Digium AEX800 Base Board Product Description
The AEX800 is a half-length PCI-Express 1.0-compliant, 8 port analog
interface card. It supports combinations of station and/or trunk/line
modules for a total of eight (8) interfaces.
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.
Like the PCI-based TDM800P, the AEX800 provides an industry first
with 8 standard two-wire, RJ-11 interfaces on a single card bracket.
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.
