Time of Day considerations

Table B-3 shows the time-of-day impacts on users and administrators. In the

Group column:

■User-visible means that times are visible and/or manipulated by the users.

■System management means that times are visible to, used by, and set by the system administrator or other switch management.

Table B-3. Time of day impacts

Use	Group	Impact
User date and time	User-visible	The date and time displayed by the system should
		indicate the user’s local time.
Automatic wakeup	User-visible	The user is able to specify and receive a wakeup
Announcements		call at the correct local time.
Do-Not-Disturb
Call Detail Recording	System	Times recorded may have to be matched against
	management	times reported by public network service providers
		(which may be dependent on the locations of trunk
		groups). Two kinds of changes:
		■ Automatic changes are set in software to
		occur at 2 AM, for example.
		■ Manual changes are still possible
Time-of-Day routing	System	Times are derived from time-of-day considerations
	management	based on the location(s) of various outgoing
		trunks. For example, a time-of-day routing change
		may take place at 5:00 PM EST because calls
		entering the public network through a New York
		trunk group receive reduced rates. Another
		change may occur at 5:00 PM PST because trunks
		in Los Angeles now provide reduced rates. Some
		or all of these times may be subject to daylight
		savings time changes.
Malicious Call Trace	System	Recorded time may need to be converted to
	management	user-perceived time. Because this feature is
		invoked infrequently, manual conversion is
		acceptable.
AUDIX	User-visible	AUDIX maintains its own time (including daylight
		savings) and is unaffected by switch
		administration. Depending on the number of DCS
		links available, it is possible to provide a different
		AUDIX switch for each time zone (or each
		location), with the AUDIX clock set to match.
