Usage guidelines
When the E1-F interface is working in unframed mode, it is a 2048 kbps interface without timeslot
division and is logically equivalent to a synchronous serial interface.
When it is operating in framed mode, it is physically divided into 32 timeslots numbered 0 through 31,
where timeslot 0 is used for synchronization.
Examples
# Set E1-F interface Serial 2/0/0 to operate in unframed mode.
<Sysname> system-view
[Sysname] interface serial 2/0/0
[Sysname-Serial2/0/0] fe1 unframed
