This feature enables signaling translation between E1 and T1 equipment and allows inexpensive T1 channel banks to connect with E1 circuits. With the improved I/O speed, the card reduces CPU usage and increases card density per server. The card is fully compatible with softswitch. Also, the open source driver supports an API interface for custom application development. The 4 port E1/T1/J1 card supports industry standard telephony voice and data protocols, including Primary Rate ISDN (both North American - National/DMS and Standard EuroISDN), SS7 signalling, analog over digital such as E&M, E&M Wink, R2 CAS, FXS/FXO loopstart and other less known voice protocol families, PPP, Cisco, HDLC, and Frame Relay data modes.
