T1 card
A T1 line supports 24 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 T1 lines are ISDN Primary Rate Interface
(PRI) and dedicated or unchannelized T1, including fractional T1. A T1 card supports up to
eight T1 lines.
