Fundamental CE1/PRI Interface Configuration Commands 165ViewSerial interface viewParametersync: Sets the synchronous/asynchronous serial interface to work in synchronousmode.async: Sets the synchronous/asynchronous serial interface to work in asynchronousmode.DescriptionUsing the physical-mode command, you can set the operating mode of asynchronous/asynchronous serial interface.By default, the synchronous/asynchronous serial interface is working insynchronous mode.ExampleSet the synchronous/asynchronous serial interface to work in asynchronous mode.[3com-Serial0/0/0]physical-mode asyncFundamental CE1/PRIInterfaceConfigurationCommandschannel-set Syntaxchannel-set set-number timeslot-list rangeundo channel-set set-numberViewCE1/PRI interface viewParameterset-number: The number of the channel set formed by bundling the timeslots onthe interface, which is in the range of 0 to 30.range: The number of the timeslots that are bundled, which is in the range of 1 to31. When specifying the timeslots to be bundled, you can specify a single timeslotby specifying a number, a range of timeslots by specifying a range betweennumber1-number2, or several discrete timeslots by specifying number1,number2-number3.
