Chapter 6. DTE Port Configuration

Bisync Protocol

The Bisync protocol option enables the FSU to connect IBM 2780/3780 bisync controllers to the host across frame relay. Both point-to-point and multi-point configurations are supported.

The FSU can decode both ASCII and EBCDIC character sets and support CRC16, parity, VRC, and LRC error checking methods. See Figure 6-7 for the Bisync protocol menu tree.
