What is DE410E/DE210E
The DE410E/DE210E is a bundling of our leading D410E/D210E product and our new EC100
Octasic DSP-based echo cancellation module. The EC100 provides a certified
carrier-grade algorithm that has been labeled a benchmark for echo cancellation for
OpenVox.
With the improved I/O speed, the card reduces CPU usage and increased card density
per server. DE410E/DE210E is fully compatible with Asterisk applications. The open
source driver supports an API interface for custom application development.
DE410E/DE210E 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.
