Configuring NTP Client
Network Time Protocol (NTP) is an IP protocol that allows you to synchronize the time on your
network devices. The NTP Client allows you to synchronize the time on your Business
Communications Manager system with the NTP Server on your network. This ensures that your
Business Communications Manager is using the same time as the other Business Communications
Manager systems and servers on your network.
There are two clocks operating on the Business Communications Manager system.
•
Business Communications Manager system clock: The system clock is used for scheduled
tasks and the time stamp on events and alarms. The NTP client synchronizes the system clock
with the NTP server time.
•
Business Communications Manager telephony clock: The telephony clock provides the time
that appears on the Business Communications Manager telephones. The telephony clock gets
its time updates from the system clock. Due to delays in the system, there may be a difference
between the system time and the time that appears on the telephones.
