NTP-B25 Set Up Name, Date, Time, and Contact Information
CTC uses the latitude and longitude to position ONS 15327 icons on the network view map. To
convert a coordinate in degrees to degrees and minutes, multiply the number after the decimal by
60. For example, the latitude 38.250739 converts to 38 degrees, 15 minutes (.250739 x 60 =
15.0443, rounded to the nearest whole number).
• Description—Type a description of the node. The description can have a maximum of 255
characters.
• Use NTP/SNTP Server—When checked, CTC uses a Network Time Protocol (NTP) or Simple
Network Time Protocol (SNTP) server to set the date and time of the node.
If you do not use an SNTP or NTP server, complete the Date and Time fields. The ONS 15327 will
use these fields for alarm dates and times. (CTC displays all alarms in the login node's time zone
for cross network consistency.)
Note
If you check the Use NTP/SNTP Server check box, type the IP address of either

If you enable a firewall for the ONS 15327 proxy server, external ONS 15327 network elements
(ENEs) must reference the gateway ONS 15327 for NTP/SNTP timing. For more information about
the proxy server feature, refer to the Cisco ONS 15327 Reference Manual.
If you reference another ONS 15327 for the NTP/SNTP server, make sure the second ONS 15327
Caution
references an NTP/SNTP server and not the first ONS 15327 (that is, do not create an NTP/SNTP timing
loop by having two ONS 15327s reference each other).
Date—If the Use NTP/SNTP Server check box is not selected, type the current date in the format
•
mm/dd/yyyy, for example, September 24, 2002 is 09/24/2002.
Time—If the Use NTP/SNTP Server check box is not selected, type the current time in the format
•
hh:mm:ss, for example, 11:24:58. The ONS 15327 uses a 24-hour clock, so 10:00 PM is entered as
22:00:00.
• Time Zone—Click the field and choose a city within your time zone from the popup menu. The
menu displays the 80 World Time Zones from -11 through 0 (GMT) to +14. Continental United
States time zones are GMT-05:00 (Eastern), GMT-06:00 (Central), GMT-07 (Mountain), and
GMT-08 (Pacific).
Click Apply.

Step 5 On the confirmation dialog box, click Yes.
Step 6 Review the node information. If you need to make corrections, repeat Steps
corrections. If the information is correct, continue with the
procedure on page
Stop. You have completed this procedure.

Using an NTP or SNTP server ensures that all ONS 15327 network nodes use the same date and
time reference. The server synchronizes the node's time after power outages or software
upgrades.
