The A8 Series of analog cards supports up to eight (8) connections per card in your Asterisk system. Using Digium's advanced quad-port interface modules, A8 Series cards can scale from one (1) to eight (8) ports.
The modular nature of the cards allows you to mix and match between line (FXO) and station (FXS) interfaces, giving you exactly the ports you need. The A8 Series cards are available in half-length PCI and PCI Express form factors.
Digium cards are compatible with all versions of Asterisk using the DAHDI driver framework. Asterisk and DAHDI are available for free from the Asterisk.org website. All cards include a five (5) year warranty
