226CHAPTER 13: FUNDAMENTAL CT1/PRI INTERFACE CONFIGURATION COMMANDS

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

Example # Set the line idle code to 0x7E on CT1/PRI interface T1 2/0.

<Sysname> system-view

[Sysname] controller t1 2/0

[Sysname-T1 2/0] idlecode 7e

itf (CT1/PRI interface view)

Syntax itf { number number type { 7e ff } }

undo itf { number type }

View CT1/PRI interface view

Parameter 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.

Description 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.

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

<Sysname> system-view

[Sysname] controller t1 2/0

[Sysname-T1 2/0] itf type ff

# Set the number of interframe filling tags to five on CT1/PRI interface T1 2/0.

<Sysname> system-view

[Sysname] controller t1 2/0

[Sysname-T1 2/0] itf number 5

loopback (CT1/PRI interface view)
