1.2.1 Configuring the Basic Parameters of DCC

Regardless of which method is used, C-DCC or RS-DCC, you must perform the tasks
described in this section.
I. Configuring the mode of the physical interface
For a synchronous/asynchronous serial interface, you must set its operating mode
depending on the connected modem. If the connected modem is asynchronous, set the
interface to operate in asynchronous mode and then enable modem dial on the
corresponding user interface. If the connected modem is synchronous, set the interface
to operate in synchronous mode.
For an ISDN BRI or PRI interface, skip this step.
Perform the following configuration in dial interface (synchronous/asynchronous serial
interface) view.
Table 1-1 Configure physical interface mode
Configure
serial port to operate in asynchronous or
synchronous mode
Configure the asynchronous serial port to
operate in protocol mode
Enable modem dial on user-interface
By default, the synchronous/asynchronous serial port operates in synchronous mode
and the asynchronous interface operates in flow mode.
Note:
For the synchronous serial port connected to the synchronous modem, there is no
need to configure the physical-mode command.
