Digium 2 Span Digital T1/E1/J1/PRI PCI-Express x1 Card and Hardware Echo Cancellation (1TE220BF)

 

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 - x1, 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 (not shown in picture). The VPMOCT064 provides the G.168 algorithm which has been labeled a benchmark for echo cancellation and performs 128ms (1024 taps) of echo cancellation across all 60 channels in E1 mode or all 48 channels in T1/J1 modes. Bundled with the VPMOCT064, the product SKU is TE220B.

 

Digium has designed the TE220 to be fully compatible and integrated with Asterisk Business Edition, AsteriskNOW, and open source Asterisk.

 

The TE220 supports industry standard telephony protocols including North American and European Primary Rate signalling as well as standard Robbed Bit, Channel Associated Signalling in addition to standard PPP, HDLC, and Frame Relay data modes.
