		DDS network, or there is a DDS failure.
Delay	Ð Select only if you do not want the DSU to respond to a network alarm condition or CMI signal. When
		selected, LSD only goes Off after repeated call attempts fail, and the period of time set in Tries Time-out
		(in the Backup option set) expires. Make sure that Auto Backup (in the Backup option set) is enabled.
