DTE/DCE mode jumper settings

The interface for each ESDI port is configured independently. Ports must be configured both for electrical interface (RS-232-C or high-speed) and mode (DTE or DCE). With the proper options set:

•An ESDI port configured as DTE appears as a terminal to the user equipment.

•An ESDI port configured as DCE appears as a modem to the user equipment.

Interface options are set by installing option jumper plugs into the sockets indicated in Table 266 on page 853 and Table 267 on page 853.
