Features
- The Digium TE121B 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.
- The Wildcard TE121B 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 TE121B 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 TE121B 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 TE120P works in both 3V and 5V slots by auto detecting the slot's voltage
- By utilizing our TDMoE (TDM over Ethernet) technology, an exclusive Digium process, you can easily connect multiple PCs equipped with the TE120P and achieve voice quality on par with single PBX implementations. Scalability for this product is derived from adding multiple TE121B's to each individual PC. Add additional cards as you need them for your expanding applications.
- The TE121B 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.
