The Digium AEX410 series cards are a half-length PCI-Express x1 modular gateway card for connecting analog telephone stations and analog POTS lines through a PC. It supports a combination of up to four single station or four single trunk modules for a total of 4 lines.

Using Digium's Asterisk® software and standard PC hardware, one can create a telephony environment that includes all of the sophisticated features of a high-end business telephone system.

The optional 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 AEX410 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.
