Digium Dual Span with Echo Cancellation Cards for Asterisk™
The TE205P is the next generation of Digium hardware that improves performance and scalability through bus mastering architecture. The TE205P provides termination of up to 60 channels of voice or data across two E1, T1, or J1 interfaces. It supports 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 This card is a 5.0v PCI slot only.
The TE207P has the same features than the TE205 but offers an on-board Octasic DSP-based echo cancellation module VPMOCT064. This 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. Furthermore, this module takes advantage of the Octasic Voice Quality Enhancement to provide superior sound quality on all calls.
The TE212P is a bundling of the TE210P product and the VPMOCT064 Octasic DSP-based echo cancellation module.
Digium's TE220 PCI Express card provides termination of up to 60 channels of voice or data across two E1, T1, or J1 interfaces in a PCIe x1 form factor. Selectable on a per-port or per-card basis, the TE220 allows E1 and T1 circuits to be mixed with full channel synchronization. Supporting PCIe x1, the TE220 may be used in any available PCIe 1.0 compliant slot - 1x, x4, x8, and x16 without considerations for voltage selection or lane size.
The TE220 may be combined with Digium's VPMOCT064 Octasic DSP-based echo cancellation module. Bundled with the VPMOCT064, the product SKU is TE220B.
