After unframed is configured on an T1 channel, it will not include the frame control
information, nor divide time slots, or implement time slot binding. And the system will
automatically create a serial interface whose number is serial number /
line-number:0 and whose rate is 1544 kbps. The interface has the same logic feature
as that of a synchronous serial interface; therefore, it can be regarded as a
synchronous serial interface for further configuration.
