The DM400A PCI Base Card is a half-length PCI 2.2 compliant card that supports from one to four telephone interfaces for connecting analog telephones or analog lines to a PC. DM400A cards are high-performance and configurable PCI telephony adapters that provide rich media processing capabilities, each base card can easily be expanded by adding up to four FXO or FXS modules. To scale this solution, simply add additional DM410A cards populated with modules.

The DM400A is fully compatible with today's existing software applications and it can easily be integrated with the Asterisk Open Source PBX/IVR platform. The open source driver supports an API interface for custom application development.
