Suited for: ISDN Primary (8 - 120 Channels)
The TE407P offers an on-board DSP-based echo cancelation module. It supports
E1, T1, and J1 environments and is selectable on a per-card or per-port basis.
The TE407Pis a bundling of our leading TE405P product and our new VPM450M Octasic
DSP-based echo cancelation module. The VPM450M provides a certified carrier-grade
algorithm that has been labeled a benchmark for echo cancelation. This new module
improves upon our older VPM400M and TE411P/TE406P products. With the VPM400M,
16ms or 128taps of echo cancelation 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 calls.
Digium has designed the TE407P 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 TE407P 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 TE407P
is for use only with a 5.0 volt PCI slot.
