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 271 on
