TE**0, The 2 port E1/T1/J1 card supports E1, T1 and J1 circuits and it is selectable on a per-card or per-port basis. 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 Asterisk softswitch. Also, the

Open source driver supports an API interface for custom application development.
