area

Syntax	area { custom europe north-america }
	undo area
View	Voice view
Parameter	custom: Busy tone defined by users.
	europe: Busy tone compliant with Europe standard.
	north-america: Busy tone compliant with North America standard.
Description	Use the area command to configure the type of busy tone for FXO voice
	subscriber line.
	Use the undo area command to restore the default type.
	By default, the busy tone compliant with the Europe standard is used.
	This command applies to 2-wire loop trunk subscriber line FXO only. Once this
	command is configured, the configuration will be effective to all the analog FXO
	voice cards on the device.
	When an FXO interface card is connected to a common subscriber line of a
	program-controlled switch, if the user on the switch side hangs up first, only by
	detecting the busy tone can the router know that the user has hung up. This is
	made possible because different switches adopt different cptone schemes with
	varying frequency spectrum characteristics, based on which the busy tone can be
	identified.
Example	# Configure the busy tone type compliant with the North America standard.
