Digium Quad T1/E1/PRI PCIe Card

Model: 1TE420F

The Digium TE420 card was designed for use with Asterisk, Switchvox, and FreePBX; providing up to 120 channels of voice and data, the Digium TE420 card has four standard RJ-45 ports. The Digium TE420 can provide four T1, E1, or J1 interfaces and support 96 T1/J1 or 120 E1 connections.  DIGIUM TE420 FEATURES: Supports up to 120 Channels, Four RJ-45 Ports, Four T1, E1, or J1 Interfaces, Status Indicator Lights.

Digium's TE420 PCI Express card provides termination of up to 120 channels of voice or data across four 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.

The VPMOCT128 provides the G.168 algorithm which has been labeled a benchmark for echo cancellation and performs 128ms (1024 taps) of echo cancellation across all 128 channels in E1 mode or all 96 channels in T1/J1 modes. Bundled with the VPMOCT128, the product SKU is TE420B. Digium has designed the TE420 to be fully compatible and integrated with Asterisk Business Edition, AsteriskNOW, and open source Asterisk. The TE420 supports industry standard telephony protocols including North American and European Primary Rate signaling as well as standard Robbed Bit, Channel Associated Signalling in addition to standard PPP, HDLC, and Frame Relay data modes.
