frame-format

Syntax	In ATM E1 interface view:
	frame-format { crc4-adm no-crc4-adm }
	In ATM T1 interface view:
	frame-format { esf-adm sf-adm }
	undo frame-format
View	ATM E1/T1 interface view
Parameter	crc4-adm: Sets the ATM over E1 framing format to 4-bit cyclic redundancy check
	ATM direct mapping (CRC4 ADM).
	no-crc4-adm: Sets the ATM over E1 framing format to no-CRC4 ADM.
	esf-adm: Sets the ATM over T1 framing format to extended super frame ADM
	(ESF ADM).
	sf-adm: Sets the ATM over T1 framing format to super frame ADM (SF ADM).
Description	Use the frame-formatcommand to configure the ATM over E1/T1 framing
	format.
