Digium Recently Released two new or actually 4 new T1 cards for use with Asterisk.

Today I posted the 4 new models on Astawerks.com

The 1st model is the Digium TE220 which is a two port T1/E1 PCI express asterisk interface. The TE220 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. 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.

The TE220B is also for sale on Astawerks.com. It provides Echo cancellation which I also recommend to my customers. you are of course going to spend a few dollars more but of course it is goign to be worth it.

The Second card that Digium released is the TE420. The Te420 is a Four Port T1/E1 PCI Express Asterisk Interface. 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.

Of course the TE420 has the Te420B model out as well which stops all echo and is defiantly worth it.

Astawerks.com Carries the entire digium product line and the entire AASTRA product line but that I will save for my next article. If you would like to have even better pricing then that listed on Astawerks.com please use the contact us page or Chat with us on the website.
