Digium TDM2420B Analog Telephony Card Information:
The Digium TDM2420B 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. It is created by combining one TDM2400P baseboard and two S400M FXS modules. With Digium's Asterisk Open Source PBX software, you can build your dream telephony environment with all of the high-end features of a business telephone system.
By using a combination of a bus-mastering PCI interface chip and Digium VoiceBus technology, the TDM2400P eliminates the need for separate channel banks and T1 interface cards.
The quad-FXO and quad FXS modules are interchangeable, enabling the creation of any combination of ports. The optional hardware echo cancellation module provides 256 taps of echo cancellation for superior echo cancellation on both FXO and FXS interfaces.
Using this card in concert with Digium's Asterisk software, standard PC hardware, and the Linux OS, you can create SMB or SOHO telephony environments capable of satisfying the needs of small or medium business applications at an industry-leading price.
