Digium Wildcard TE122P PCI ISDN PRI Card

The Digium TE122P 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 Digium TE122P 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 Digium TE122P is a single span, selectable T1 (24-channel), E1 (32-channel), or J1 (24-channel) card utilizing Digium''s VoiceBus technology. VoiceBus technology allows the Digium TE122P 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 Digium TE122P 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 Digium TE122P works in both 3.3V and 5V PCI slots by auto detecting the slot''s voltage. The bus-mastering Digium TE122P improves I/O speed over slave-only architectures, resulting in reduced CPU usage and increased card density per server. The cards provide the power to interconnect traditional telephony systems with emerging Voice-over IP (VoIP) technologies.

Target Applications

• Legacy PBX/IVR Services
• Voice-over Internet Protocol (VoIP) services
• Complex IVR Trees
• "Meet-Me" Bridge Conferencing
• VoIP Gateways (supports SIP, H.323 and IAX)
• Calling Card Platforms
• Voice/Data Router (replace expensive routers)
• PRI Switch Compatibility – Network or CPE

By utilizing Digium''s TDMoE (TDM over Ethernet) technology, an exclusive Digium process, you can easily connect multiple PCs equipped with the Digium TE122P and achieve voice quality on par with single PBX implementations. Scalability for this product is derived from adding multiple Digium TE122P cards to each individual PC adding additional cards as you need them for your expanding applications. The Digium TE122P 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. The Digium TE122P supports industry standard telephony and data protocols, including Primary Rate ISDN (both N. American and Euro Standard) protocol families for voice, PPP, Cisco HDLC, and Frame Relay data modes. Both line-side and trunk-side interfaces are supported, as well as advanced call features.

Improving upon the prior TE120P which does not offer expansion capabilities, the Digium TE122P may be combined with Digium''s VPMADT032 echo cancellation module to deliver 128ms of echo cancellation across 30 channels in E1 mode or 24 channels in T1 mode.

The Digium TE122P has been designed to be fully compatible with existing software applications. They are fully integrated with Digium''s Asterisk software. The open source drivers for these cards support an API for custom application development. With the combination of Digium hardware and Asterisk software, numerous telephony configurations are possible. From the traditional PBX to VoIP Gateways, Digium solutions are paving the way for a new generation of worldwide communications.
