The Wildcard AEX2400 is a full-length PCI-Express 1.0-compliant card that supports FXS and FXO station interfaces for connecting analog telephones and analog POTS lines through a PC. Using Digium's Asterisk Open Source PBX software and standard PC hardware, one can create a SOHO (Small Office Home Office) telephony environment that includes all the sophisticated features of a high-end business telephone system.

Note: The AEX2400 is the PCI Express 1x version of the Digium TDM2400P. If you require a regular PCI version of this card, please order the TDM2400P.

The AEX2400 takes the place of an expensive channel bank and brings the system price point to a low level. By using X400M and S400M modules with the AEX2400, one can create a solution with support for a range of telephones. To scale this solution, simply add additional AEX2400 cards populated with modules.
