D410 Series

The OpenVox D410 Series is the world’s most affordable single-port T1/E1/J1 card and offers excellent voice quality on telephone systems. It supports up to 120 voice calls or 8,192 Mbps full-duplex data throughput over four T1, E1, or J1 lines. It fully utilizes the Octasic® hardware echo cancellation module.

The D410 Series features an echo cancellation module based on onboard Octasic® DSP. It supports E1, T1, and J1 environments. It can be selected per card or per port. This feature enables signaling translation between E1 and T1 equipment and allows low-cost T1 channel banks to connect to E1 circuits. The EC module based on Octasic® DSP enables users to eliminate echo tails of up to 128 ms or 1024 taps across 128 channels in E1 mode or 96 channels in T1/J1 mode. In addition, this module uses Octasic® voice quality enhancement to provide superior sound quality on all calls.

The D410 Series supports industry-standard telephony and data protocols, including Primary Rate ISDN protocol families (N. American and Standard Euro) for voice, PPP, Cisco, HDLC, and Frame Relay data modes. Line-side and trunk-side interfaces are supported.

The D410 Series works with Asterisk®, Elastix®, FreeSWITCH™, PBX in a Flash, trixbox®, Yate™, and IPPBX/IVR projects, as well as other open-source and proprietary PBX, Switch, IVR, and VoIP gateway applications.
