■ CT3 Interface view
Description A T1 line in unframed mode does not contain the frame control information; it
cannot be divided into timeslots. Naturally, no timeslot bundling can be performed on
it. In this case, the system automatically creates a serial interface numbered serial
number / line-number:0 for it. This interface operates at 1544 kbps and has the
same logic features of a synchronous serial interface on which you can make other
configurations.
