E1 card
The E1 card provides connections to up to eight E1 lines. An E1 line supports 32 64Kbps
channels, each of which can transmit and receive data or digitized voice. The line uses framing
and signaling to achieve synchronous and reliable transmission. The most common
configurations for E1 lines are ISDN Primary Rate Interface (PRI) and unchannelized.
