Digium 4E1/T1 port cards

Digium Quad Span with Echo Cancellation Cards for Asterisk™

The TE405P is the next generation of Digium hardware that improves performance and scalability through bus mastering architecture. The TE405P provides termination of up to 120 channels of voice or data across four 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 TE407P has the same features than the TE405 but offers an on-board Octasic DSP-based echo cancellation module VPMOCT128. This module enables users to eliminate echo tails up to 128ms or 1024 taps across all 128 channels in E1 mode or 96 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 TE410P is the equivalent to te TE405P but supports 3.3v PCI slot only - typically available on newer motherboards and in 64-bit PCI bus architectures.

The TE412P is a bundling of the TE410P product and the VPMOCT128 Octasic DSP-based echo cancellation module.

Digium's TE420 PCI Express card provides termination of up to 120 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 TE420 allows E1 and T1 circuits to be mixed with full channel synchronization. Supporting PCIe x1, the TE420 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 TE420 may be combined with Digium's VPMOCT128 Octasic DSP-based echo cancellation module. Bundled with the VPMOCT128, the product SKU is TE420B.
