CONSIDERATIONS	When the system administrator assigns lines to a basic telephone, the
	administrator must provide the user with a list of codes for the lines
	and/or line pools he or she can access.
	While Night Service with Outward Restriction is in effect, people with
	basic telephones cannot enter a password to make calls. To allow them
	to make after-hours calls, the administrator must assign these basic
	telephones to the Exclusion list. (See “Night Service.”)
	Basic telephones can receive ringing intercom calls, but not intercom calls
	with voice announcement.
