If the Network Time Protocol (NTP) feature is enabled in DB Programming, the network date and time automatically synchronizes daily at 12:15 AM with an identified atomic clock.
Setting Network Date and Time
Occasionally, the network time or date needs to be reset, such as when the system is defaulted or when daylight-saving time/British summer time is implemented. Any system administrator can change the date and time that appears on all display endpoints and that appears in the SMDR reports in the network. The day of the week is automatically calculated and set by the system when the date is entered. If you make a mistake while setting network date and time, MUTE to backspace or press *or CANCEL to leave it unchanged and start over.
To set the network date and time:
1. While on-hook, enter the Set Network Date and Time feature code (9810). Your display shows DATE <current date>.
2. If you do not need to change the date, press # or ACCEPT to skip to the TIME XX:XX prompt.
3. Use the dialpad buttons to enter the month, day, and year. For example, press 020306 for February 3, 2006. When finished, the display shows TIME <current time>.
If you entered the date incorrectly, the display shows INVALID DATE, and you are prompted to enter a new date.
If you do not need to change the time, press # or ACCEPT twice to exit. The display shows SYSTEM DATE AND TIME UPDATED.
4. Use the dialpad buttons to enter the time in hours and minutes. For example, enter 0900 for 9:00.
If you entered the time incorrectly, the display shows INVALID TIME, and you are prompted to enter a new time.
5. If the node is set for 12-hour display format, the display shows SELECT AM OR PM (AM=1 PM=2). Press 1 (or the AM menu button) for AM or press 2 (or the PM menu button) for PM. The display shows SYSTEM DATE AND TIME UPDATED. If you press any button other than 1 or 2, the display shows INVALID TIME, and you are prompted to enter a new time.
Synchronizing Network Time
System administrators can synchronize the minutes past the hour across the network without changing the hour. This is useful when the nodes are in different time zones.
If the node time is off by more than 30 minutes, synchronizing the minutes may cause the hour to change. Also, network time is automatically synchronized every day at 12:30 AM (00:30), using the time setting on the node with the lowest number.
Or, if the Network Time Protocol (NTP) support feature is enabled, the system updates the network time in accordance with an atomic clock referenced to the system time zone.
To synchronize the clocks in all nodes in the network:
While on-hook, enter the Synchronize Network Time feature code (9811). You hear a confirmation tone, and the display shows NETWORK TIME SYNCHRONIZED.
