Digital 1E1 PCI-Express board OpenVox DE130E

Digital 1E1 PCI-Express card OpenVox DE130E - cost-effective, high-performance and flexible in configuration single-port PCI-Express card equipped with echo cancellation module Octasic DSP Echo Cancellation, which provides high performance and voice transmission over T1, E1 and J1 interfaces.

OpenVox DE130E is an upgraded product of DE115E and the most advanced single-port digital card with high quality in the open source community. High-quality digital single-port PCI-Express DE130E card is equipped with Octasic DSP Echo Cancellation module. Octasic echo cancellation module provides high quality voice transmission over T1, E1 and J1 interfaces. Octasic echo cancellation module allows users to eliminate echo pulses within 128ms (1024 taps) on all 32 channels in E1 stream or on 24 channels in T1/J1 streams. Leading innovations provide users with the ability to adjust the interrupt frequency to reduce the CPU load up to 70% and ensures compatibility with all available motherboards. The OpenVox DE130E board works with Asterisk, Elastix, FreeSWITCH, PBX in a Flash, trixbox, Yate and IPPBX/IVR, as well as with Open Source PBX, Switch, IVR, and VoIP gateway applications. OpenVox DE130E is an economical solution for integrating an office IP PBX with digital communication lines - using similar gateways can cost several times more.
