Digium AEX800 Base PCI Card (PCIe) 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.
Like the PCI-based TDM800P, the Digium 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 Digium AEX800 reduces part complexity, cable clutter, and points of failure.
The Digium 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 Digium 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 the Digium AEX800 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.
