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 (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.
Features:
2 Digital Interface Ports Support both Voice and Data
Selectable T1, E1, ir JI Mode
PCI-Express1.0 Compliant
Compatible with PCI-E X1, X4, X8 and X16 slots
Available without VPM0CT64 Hardware Echo Cancellation Module as TE220
