The Digium TDM410 is a half-length PCI 2.2-compliant modular gateway card for connecting analog telephone stations and analog POTS lines through a PC. It supports a combination of up to four station or trunk modules for a total of 4 lines.
Digium has released the TDM410 range of analog interface cards to replace the TDM400 product, which has now been discontinued.
Using Digium's Asterisk software and standard PC hardware, one can create a telephony environment that includes all of the sophisticated features of a high-end business telephone system.
Using an industry-standard bursting, bus-mastering interface chip that is found within millions of PC systems worldwide, and Digium VoiceBus technology, the TDM410 eliminates the requirement for external gateways, with industry-leading performance and price. The trunk and station modules are interchangeable, allowing the creation of any combination of interfaces. The optional hardware echo cancellation module provides 1024 taps (128 milliseconds) of echo cancellation for superior voice quality on both trunk and station interfaces. Scaling of this solution is accomplished by adding additional TDM410 or other Digium analog interface cards.
The naming convention for the TDM bundles is as follows: TDM4 X Y B/E. Where "TDM" denotes that the card is TDM, X denotes the number of FXS modules, Y denotes the number of FXO modules, and B indicates that that this product is a bundle without hardware echo cancellation module, and E indicates this is a bundle with hardware echo cancellation.
