Parameters
line-number: Specifies a T1 line number in the range of 1 to 28.
Usage guidelines
A T1 line in unframed mode does not contain the frame control information or support timeslot division.
The system automatically creates a 1544-kbps serial interface numbered serial number/line-number:0.
This interface has the same logical features as a standard synchronous serial interface. You can configure
this serial interface in the same way you configure a standard synchronous serial interface.
Examples
# Set T1 line 1 on T3 2/4/0 to operate in unframed mode.
<Sysname> system-view
[Sysname] controller t3 2/4/0
