Digium - TDM2411B - 24 port modular analog PCI 3.3/5.0V card with 4 Station and 4 Trunk interfaces

The Wildcard TDM2400P is a full-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 TDM2400P 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 TDM2400P, one can create a solution with support for a range of telephones. To scale this solution, simply add additional TDM2400P cards populated with modules.

What are FXS and FXO?
FXS = Foreign Exchange Station (Green Modules for TDM400P)
FXO = Foreign Exchange Office (Red Modules for TDM400P)

An FXS device initiates and sends ringing voltage. FXS sends the voltage to an FXO device, which receives it.

The phone receiving the call is the last FXO device in the chain, and when it receives voltage from an FXS device, the phone will ring.

Connect the outside line to an FXO port on your Asterisk server to receive voltage from the outside lines.

Connect the phones to FXS ports on your Asterisk server. When the FXO module in your Asterisk Server receives the voltage, it will then generate voltage using the FXS module and send it to your analog phone.

Note: The 12V power connector is required for the operation of FXS modules. It is not required for the operation of FXO modules.

The naming convention for the TDM2400 bundles is as follows: TDM24 X Y B
TDM24. "TDM24" denotes that the card is TDM2400P, "X" denotes the number of FXS modules, "Y" denotes the number of FXO modules, and "B" indicates that this product is a bundle without Echo Cancellation. "E" indicates that this product is a bundle with Echo Cancellation.

Please note: On the TDM2400P, one module is equal to 4 ports. The "X" and "Y" denote modules, NOT ports.
