Digium TDM400P Quad TDM PCI Wildcard with 4 Analog Ports

The Wildcard TDM400P is a half-length PCI 2.2-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.

The TDM400P takes the place of an expensive channel bank and brings the system price point to a low level. By using X100M and S100M modules with the TDM400P, one can create a solution with support for a range of telephones. To scale this solution, simply add additional TDM400P cards populated with modules.
