AT&T MLS-12TM, MLS-12DTM, MLS-6TM manual Night Service Group, Code #504

Night Service Group	Code: #504
	Description: Identifies the extensions in the Night Service Group. When Night
	Service is on and a call comes in, all extensions in the Night Service Group ring
	immediately. In addition, restricted Night Service (when the system has a pass-
	word) limits the Night Service Group extensions to dialing only numbers on the
	Emergency Phone Number List (#403) and Marked System Speed Dial Numbers
	(p. 3-34).
	Valid Entries:	✓ 1 = Extension is in the group
		2 = Extension is not in the group
	Considerations:
	■ Do not include hotline extensions in the Night Service Group.
	■ If you program a System Password (#403) as well as Night Service (#503),
	extensions in the Night Service Group will not be able to make outside calls
	(other than Emergency Numbers and marked System Speed Dial Numbers)
	without first entering the password. The system is programmed at the fac-
	tory with all extensions in the Night Service Group. Therefore, remove any
	extensions from the Night Service Group that should be allowed to make out-
	side calls at night, unless of course the person at that extension knows the
	password.
	Programming Steps:
	1. Press [ Feature ] [ 0 ] [ 0 ] [ System Program ] [ System Program ] [ # ] [ 5 ] [ 0 ] [ 4 ] . The
	display reads:
			NS Group
			Extension:
	2. Enter the extension to be programmed. For example, to program
	extension 13, press [ 1 ] [ 3 ] . The display reads:
			NS Group 13
			1 Assigned
	3. To remove the extension from the group, press [ Next Data ] until the
	display	reads:

NS Group 13

2 Not Assigned

To program another extension, press [ Next Item ] or [ Prev Item ] until the extension number shows on the display. Repeat step 3.
