Chapter 7: Configuration
Setting up time and date
Page 7-94
A separate NTP server (including APs/BHMs receiving NTP data) is
addressable from the AP/BHM.
If the AP/BHM needs to obtain time and date from a CMM4, or a separate
NTP server, enter the IP address or DNS name of the CMM4 or NTP
server on this tab. To force the AP/BHM to obtain time and date before
the first (or next) 15-minute interval query of the NTP server, click Get
Time via NTP.
The polling of the NTP servers is done in a sequential fashion, and the
polling status of each server is displayed in the NTP Update Log section
of the Time Configuration page. An entry of 0.0.0.0 in any of the NTP
Server fields indicates an unused server configuration.
NTP Server(s) in Use
Lists the IP addresses of servers used for NTP retrieval.
Time Zone
The Time Zone option may be used to offset the received NTP time to
match the operator’s local time zone. When set on the AP/BHM, the
offset is set for the entire sector SMs (or BHS) are notified of the current
Time Zone upon initial registration). If a Time Zone change is applied,
the SMs(or BHS) is notified of the change in a best effort fashion,
meaning some SMs//BHSs may not pick up the change until the next re-
registration. Time Zone changes are noted in the Event Log of the
AP/BHM and SM/BHS.
System Time
The current time used by the system.
Last NTP Time
Update
The last time that the system time was set via NTP.
Time
This field may be used to manually set the system time of the radio.
Date
This field may be used to manually set the system date of the radio.
NTP Update Log
This field shows NTP clock update log. It includes NTP clock update Date
and Time stamp along with server name.
