Digium TE412P, for 3.3V slots
Add to Cart
The TE412P offers an on-board DSP-based echo cancellation
module. It supports E1, T1, and J1 environments and is
selectable on a per-card or per-port basis.
The TE412P is a bundling of our leading TE410P product and
our new VPM450M Octasic DSP-based echo cancellation module.
The VPM450M provides a certified carrier-grade algorithm
that has been labeled a benchmark for echo cancellation.
This new module improves upon our older VPM400M and
With the VPM400M, 16ms or 128taps of echo cancellation were
possible across 128 channels. The new VPM450M enables users
to eliminate echo tails up to 128ms or 1024 taps across all
128 channels in E1 mode or 96 channels in T1/J1 modes.
Further, this module takes advantage of the Octasic Voice
Quality Enhancement to provide superior sound quality on all
Digium has designed the TE412P to be fully compatible with
existing software applications and it is fully integrated
with the Asterisk Open Source PBX/IVR platform. Also, the
open source driver supports an API interface for custom
application development. With the combination of Digium
hardware and Asterisk software, numerous combinations of
telephony configurations are possible. From the traditional
PBX to VoIP Gateways, Digium solutions are paving the way
for a new generation of worldwide communications.
The TE412P supports industry standard telephony and data
protocols, including Primary Rate ISDN (both N. American and
Standard Euro) protocol families for voice, PPP, Cisco,
HDLC, and Frame Relay data modes. Both line-side and
trunk-side interfaces are supported, also included are
advanced call features. The TE412P is for use only with a
3.3 volt PCI slot.
Certifications for the TE412P are pending.
Designed for Asterisk
Digium has designed the TE412P to be fully functional
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 TE412P performs high quality echo
cancellation and Voice Quality Enhancements (VQE). The
Digium TE412P 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 TE407P/412P 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 very high marks and was labeled a
benchmark-algorithm for echo cancellation.
