Digium TDM402B - 2 FXO PCI Card (TDM402BF)

The TDM402B is a TDM410 card with 2 FXO modules attached and no echo cancellation module (VPMADT032).

Digium analog cards were created for connecting analog telephones and analog POTS lines through a PC. Using one of our analog cards in concert with Digium''s Asterisk software, standard PC platforms, and the Linux OS, one can create telephony environments capable of satisfying the needs of business applications with industry-leading quality.

Features

• 4 Ports for connecting analog telephones or POTS lines
• Half-length Analog Card
• Up to 4 FXS or FXO Modules
• High Performance Echo Cancellation (HPEC) Software (Optional)

The analog cards, with their interchangeable single and quad FXS and FXO modules, can eliminate the requirement for separate channel banks or access gateways. Digium''s commercial, tollquality High Performance Echo Cancellation (HPEC) software is available to our analog customers at no additional cost. The optional VPMADT032 hardware echo cancellation module provides the same toll-quality as HPEC, but without the performance impact of a software based solution. Scaling of an analog card solution is accomplished by adding additional cards.

Digium''s analog cards utilize patent pending VoiceBus technology. VoiceBus technology allows these cards to use an industry standard, bus-mastering interface as found in millions of PCs worldwide. VoiceBus maximizes system compatibility and prevents system conflicts.
