The OpenVox D410P supports E1, T1 and J1 environments. It is selectable on a per-card or per-port basis. This feature enables signaling translation between E1 and T1 equipments and allows inexpensive T1 channel banks to connect with E1 circuits.
With the improved I/O speed, the card reduces CPU usage and increased card density per server. D410P is fully compatible with Asterisk applications. The open source driver supports an API interface for custom application development.
D410P 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.
