Digium TE212P, for 3.3V slots
Add to Cart
The Digium TE212P is the next wave of Digium
hardware to offer on-board Octasic echo cancellation, each
compatible with a 5.0- volt and 3.3-volt slot respectively.
Echo cancellation is supported for two full T1s or J1s (48
channels), or E1s (62 channels) to eliminate echo and
improve voice quality in situations where software echo
cancellation is not sufficient, where echo cancellation is
not done at the CO, or where CPU utilization must be
By supporting 128ms of echo cancellation on each and every
channel, the card will perform in the most difficult
environments while providing capacity/length tradeoff.
The Digium TE212P provides robust echo cancellation
on the network side for situations involving a 4-to-2 wire
hybrid, giving users its highest performance.
Designed for Asterisk
Digium has designed the TE207P/TE212P to be fully compatible
with existing software applications and it is fully
integrated with the open source Asterisk as well as with
Asterisk Business Edition. The open source driver supports
an API interface for custom application development, so
developers can more accurately meet their needs.
Superior Voice Quality
The new Digium TE212P performs high quality echo
cancellation and Voice Quality Enhancements (VQE). The
Digium TE212P adds a series of Octasic voice processors
which apply a Least Squares adaptive filter algorithm with
frequency awareness providing superior performance for
today’s solutions. Therefore, the Digium TE212P can
significantly increase density in voice gateways while
offloading DSPs to maximize their use for other features.
Carrier-Grade Echo Cancellation
When tested by leading carrier labs, the Octasic algorithm
received the highest marks and was labeled a
benchmark-algorithm for echo cancellation.
