Setting Physical Attributes for a Synchronous Serial Interface
Setting Physical Attributes for a Synchronous Serial Interface
Context
A serial interface can function as a DTE interface or a DCE interface. When functioning as a DTE, the device receives clock signals from a DCE.
Physical attributes of a synchronous serial interface have default values. To modify these parameters, perform the following steps.
Procedure
Setting physical attributes for a synchronous serial interface functioning as a DTE interface
Step 7 and Step 8 cannot be performed on the same serial interface.
Run system-view
The system view is displayed.
Run interface serialinterface-number
The serial interface view is displayed.
Run physical-modesync
The serial interface is configured to work in synchronous mode.
By default, a serial interface works in synchronous mode.
Run virtualbaudratebaudrate
The virtual baud rate is set for the synchronous serial interface.
By default, the virtual baud rate of a synchronous serial interface is 64000 bit/s.
Run clock dte { dteclk1 | dteclk2 | dteclk3 }
The clock mode is set for a synchronous serial interface on the DTE.
By default, the clock mode of a synchronous serial interface is dteclk1 on the DTE.
Run invert transmit-clock
The device is configured to invert clock signals transmitted by the synchronous serial interface.
By default, clock signals transmitted by a synchronous serial interface are not inverted.
Run invert receive-clock
The device is configured to invert clock signals received by the synchronous serial interface.
By default, clock signals received by a synchronous serial interface are not inverted.
Run invert receive-clock auto
The device is configured to automatically invert clock signals received by the synchronous serial interface.
By default, clock signals received by a synchronous serial interface are not inverted.
Run detect dsr-dtr
Detection of DSR and DTR signals is enabled on the synchronous serial interface.
By default, detection of DSR and DTR signals is enabled on a synchronous serial interface.
Run detect dcd
Detection of DCD signals is enabled on the synchronous serial interface.
By default, detection of DCD signals is enabled on a synchronous serial interface.
Run reverse-rts
The device is configured to invert RTS signals of the synchronous serial interface.
By default, RTS signals of a synchronous serial interface are not inverted.
