frame-format (CT1/PRI interface view)

Syntax	frame-format { esf sf }
	undo frame-format
View	CT1/PRI interface view
Parameter	sf: Sets the framing format to super frame (SF).
	esf: Sets the framing format to extended super frame (ESF).
Description	Use the frame-formatcommand to set the framing format on the CT1/PRI
	interface.
	Use the undo frame-formatcommand to restore the default, that is, esf.
	CT1/PRI interfaces support two framing formats, that is, SF and ESF. In SF format,
	multiple frames can share the same FSC and signaling information, so that more
	significant bits are available for transmitting user data. The use of ESF allows you
	to test the system without affecting the ongoing service.
Example	# Set the framing format of interface T1 2/0 to SF.

idlecode (CT1/PRI interface view)

Syntax	idlecode { 7e ff }
	undo idlecode
View	CT1/PRI interface view
Parameter	7e: Sets the line idle code to 0x7E.
	ff: Sets the line idle code to 0xFF.
Description	Use the idlecode command to set the line idle code on the CT1/PRI interface.
	Two types of line idle code are available: 0x7E and 0xFF.
	Use the undo idlecode command to restore the default, that is, 0x7E.
