Digium TE220B: dual E1, PCI Express, Hardware EC

Digium Wildcard TE220B Dual E1 PCI Express with Hardware EC

The TE220B is the next generation of Digium hardware that improves performance and scalability through bus mastering architecture. The TE205P, TE207P, TE210P and TE212P supports both E1 and T1/J1 environments and is selectable on a per-card or per-port basis. This feature enables signaling translation between E1 and T1/J1 equipment and allows inexpensive T1/J1 channel banks to connect with E1 circuits. Because the TE205P, TE207P, TE210P and TE212P improves I/O speed over slave-only architecture, the result is reduced CPU usage and increased card density per server. Digium has designed the TE205P, TE207P, TE210P and TE212P to be fully compatible with existing software applications and it is fully integrated with the Asterisk Open Source PBX/IVR platform. Also, the open source driver supports an API interface for custom application development. With the combination of Digium Hardware and Asterisk software, numerous combinations of telephony configurations are possible. From the traditional PBX to VoIP Gateways, Digium solutions are paving the way for a new generation of worldwide communications.
 

The TE207P is a bundling of our leading TE205P product and our new VPMOCT064 Octasic DSP-based echo cancellation module. The TE207P is Digium's and the industry's first two-port digital card featuring hardware-based echo cancellation. The new module enables users to eliminate echo tails up to 128ms or 1024 taps across all 64 channels in E1 mode or 48 channels in T1/J1 modes. Further, this module takes advantage of the Octasic Voice Quality Enhancement to provide superior sound quality on all calls.

The TE205P, TE207P, TE210P and TE212P all support industry standard telephony and data protocols, including Primary Rate ISDN (both N. American and Standard Euro) protocol families for voice, PPP, Cisco, HDLC, and Frame Relay data modes. Both line-side and trunk-side interfaces are supported, also included are advanced call features. The TE205P & TE207P are for use only with a 5.0-volt PCI slot. The TE210P & TE212P are for use only with a 3.3-volt PCI slot.
