The Digium® TDM410 is a half-length PCI 2.2-compliant modulargateway card for connecting analog telephone stations and analog POTSlines through a PC. It supports a combination of up to four station ortrunk modules for a total of 4 lines.
Using Digium’s Asterisk® software and standard PC hardware, one cancreate a telephony environment that includes all of the sophisticatedfeatures of a high-end business telephone system.
Using an industry-standard bursting, bus-mastering interface chipthat is found within millions of PC systems worldwide, and DigiumVoiceBus™ technology, the TDM410 eliminates the requirement forexternal gateways, with industry-leading performance and price. Thetrunk and station modules are interchangeable, allowing the creation ofany combination of interfaces. The optional hardware echo cancellationmodule provides 1024 taps (128 milliseconds) of echo cancellation forsuperior voice quality on both trunk and station interfaces. Scaling ofthis solution is accomplished by adding additional TDM410 or otherDigium analog interface cards.
