DM800A is a stardard full-length PCI 2.2 compliant card for connecting analog telephones and analog POTS lines through a PC. It supports a combination of up to 8 FXS and/or FXO modules for a total of 8 lines. Use the telephony card selector to identify a card that fits your requirements.
Using stardward Asterisk Open Source PBX software and standard PC hardware, one can create a telephony environment that includes all the sophisticated features of a high-end business telephone system.
Using an industry-standard bursting, bus-mastering PCI interface chip that is found within millions of PC systems worldwide, and VoiceBus technology, the DM800A eliminates the requirement for separate channel bank and T1 interface cards, at an industry-leading price. The single- FXO and single-FXS modules are interchangeable, allowing the creation of any combination of interfaces.
