shdsl annex

Syntax	shdsl annex { a b }
	undo shdsl annex
View	ATM (G.SHDSL) interface view
Parameter	a: Annex A.
	b: Annex B.
Description	Use the shdsl annex command to configure the annex standard supported on
	the G.SHDSL interface. You cannot activate a link with different standard types at
	its two ends.
	Use the undo shdsl annex command to restore the default, that is, Annex B.
	Annex A is dominant in North America while Annex B is dominant in Europe.

	region where your network is located. When ATU-C and ATU-R use different
	standards, G.SHDSL cannot set up connection.

	[Sysname] interface atm 5/0
	[Sysname-Atm5/0] shdsl annex a
