The line idle code is sent in the timeslots that are not bundled into the logical 
channels on the interface.

number number: Sets the number of interframe filling tags (an interframe filling 
tag is one byte in length). The number argument ranges from 0 to 14.

type { 7e | ff }: Sets the interframe filling tag to 0x7E by specifying the 7e keyword 
or to 0xFF by specifying the ff keyword. On CT1/PRI interfaces, the default 
interframe filling tag is 0x7E.

Use the itf command to set the type and the number of interframe filling tags on 
the CT1/PRI interface. Two types of interframe filling tag are available: 0x7E and 
0xFF.

Use the undo itf command to restore the default.

By default, the interframe filling tag is 0x7E, the number of interframe filling tags 
is 4.

Interframe filling tags are sent when no service data is sent on the timeslots 
bundled into logical channels on a CT1/PRI interface.

# Set the interframe filling tag to 0xFF on CT1/PRI interface T1 2/0.
