Digital 4E1 PCI Card OpenVox DE430P

The OpenVox DE430P Digital 4E1 PCI Card is a cost-effective digital and flexible PCI card with support for four E1 channels, which has an Octasic Hardware Echo Cancellation Module to ensure the highest voice quality over T1, E1 and J1 streams.

DE430P is an upgraded product of DE410P and the most advanced four-port high-quality card in the open source community. High-performance digital OpenVox DE430P card with PCI 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%. DE430P is equipped with a built-in Octasic DSP-based echo cancellation module. Octasic echo cancellation module allows users to eliminate echo pulses within 128ms (1024 taps) on all 128 channels in E1 stream or 96 channels in T1/J1 streams. Also, this module uses Octasic Voice Quality Enhancement technology to provide excellent voice quality for all calls. DE430P is compatible with all existing motherboards. OpenVox DE430P works with Asterisk, Elastix, FreeSWITCH, PBX in a Flash, trixbox, Yate and IPPBX/IVR, as well as Open Source PBX, Switch, IVR, and VoIP gateway applications. This voice board is an inexpensive solution for connecting an office telephone station to high-quality communication channels; using similar gateways can cost several times more.
