Digital 4E1 PCI-Express Board OpenVox DE430E

Digital 4E1 PCI-Express card OpenVox DE430E is a cost-effective digital and flexible card with PCI-Express interface and support for four E1 channels, equipped with Octasic Hardware Echo Cancellation Module to provide the highest voice quality over T1, E1 and J1 stream.

The DE430E is an upgraded product of the DE410E and the most advanced four-port high-quality card in the open source community. The high-performance digital OpenVox DE430E card with PCI-Express interface and intelligent interrupt management system to ensure high performance and voice transmission. Leading innovations provide users with interrupt frequency adjustment to reduce the CPU load by up to 70%. The DE430E board has a built-in Octasic DSP-based echo cancellation module. The Octasic echo cancellation module allows users to eliminate echo pulses within 128ms (1024 taps) on all 128 channels in the E1 stream or on 96 channels in the T1/J1 streams. Also, this module uses Octasic Voice Quality Enhancement technology to provide excellent voice quality for all calls. The DE430E board is compatible with all existing motherboards. OpenVox DE430E 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. This voice board is an economical solution for integrating an office IP PBX with digital communication lines - using similar gateways can cost several times more.
