Digium TE122B Single Span T1/E1 card with echo cancellation module

The Wildcard TE122 is a high-performance, cost effective digital telephony interface card with the power to create a seamless network, interconnecting traditional telephony systems with emerging Voice over IP technologies.

Used in conjunction with Asterisk, the TE122 can be used to deliver a wide range of PBX and IVR services to the network or handset including Voicemail, Call Conferencing, Three-way Calling, and VoIP Gateways.

The Wildcard TE122 is a single span, selectable T1 (24-channel), E1 (32-channel), or J1 (24-channel) card. The card utilizes Digium's VoiceBus technology. VoiceBus technology allows the TE122 to use an industry standard bus-mastering PCI interface, as found in millions of PCs worldwide, to maximize system compatibility and eliminate system conflicts.

The TE122 supports both voice and data modes on its single span. For example, the card can support 12 channels dedicated to voice, routed directly to the Asterisk Open Source PBX, and 12 to data, handled by the underlying Linux operating system, thus eliminating the need for an external router. The TE122 works in both 3V and 5V slots by auto detecting the slot's voltage.

By utilizing TDMoE (TDM over Ethernet) technology, an exclusive Digium process, you can easily connect multiple PCs equipped with the TE122 and achieve voice quality on par with single PBX implementations. Scalability for this product is derived from adding multiple TE122s to each individual PC. Add additional cards as you need them for your expanding applications.

The TE122 supports industry standard telephony and data protocols, including both RBS and Primary Rate ISDN (PRI) protocol families for voice and PPP, Cisco HDLC, and Frame Relay data modes. The board drives both line-side and trunk-side interfaces, including call features.

Using this card in concert with Digium's Asterisk software, standard PC hardware, and the Linux OS, you can upgrade your PBX to a sophisticated telephony environment capable of supporting both voice and data channels.

The TE122 is the new replacement for the TE110P and TE120P, and now also supports an optional echo cancel module the VPMADT032. It is also available as the Digium TE122B with hardware echo cancellation.
