Appendix B 89
Appendix B — Transmission Modes
The EPC/X host adapter and the T1 Modem Bank transmit synchronous data in one of 75 modes. These modes are
numbered 0 - 74, and each corresponds to a specific combination of wiring mode (4-Wire or 8-Wire), clocking
method (internal, external or self-clocking) and baud rate. The 75 modes and their definitions are listed below:
