Syntax
By default, E1 lines are up.
This command affects not only the specified E1 line but also the serial interfaces
formed by E1 line bundling. Performing the e1 shutdown command on the
specified E1 line shuts down all these serial interfaces. Data transmission and
receiving stop as a result. Likewise, performing the undo e1 shutdown command
restarts all these serial interfaces.

By default, an E1 line operates in framed mode (CE1 mode).
An E1 line in unframed mode does not contain the frame control information; it
cannot be divided into timeslots. The system automatically creates a serial
interface numbered serial number/line-number:0 for it. This interface operates at
2048 kbps and is logically equivalent to a synchronous serial interface on which
you can make other configurations.
