Chapter 4 Turn Up Node
Enter the following information in the fields listed:
Step 3
Node Name—Type a name for the node. For TL1 compliance, names must begin with an alpha
•
character and have no more than 20 alphanumeric (a-z, A-Z, 0-9) characters.
Contact—Type the name of the node contact person and the phone number, up to 255 characters
•
(optional).
Latitude—Enter the node latitude: N (North) or S (South), degrees, and minutes (optional).
•
Longitude—Enter the node longitude: E (East) or W (West), degrees, and minutes (optional).
•
Tip
CTC uses the latitude and longitude to position ONS 15454 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 (0.250739 x 60 =
15.0443, rounded to the nearest whole number).
• Description—Type a description of the node. The description can be 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 15454 will
use these fields for alarm dates and times. By default, CTC displays all alarms in the CTC computer
time zone for consistency. To change the display to the node time zone, complete the
Display Alarms and Conditions Using Time Zone" task on page
Note
If you check the Use NTP/SNTP Server check box, type the IP address of one of the following:
–
–
If you check gateway network element (GNE) for the ONS 15454 SOCKS proxy server (see
"DLP-A249 Provision IP Settings" task on page
gateway ONS 15454 for NTP/SNTP timing. For more information about the ONS 15454 gateway
settings, refer to the "CTC Network Connectivity" chapter in the Cisco ONS 15454 Reference
Manual.
If you reference another ONS 15454 for the NTP/SNTP server, make sure the second ONS 15454
Caution
references an NTP/SNTP server and not the first ONS 15454 (that is, do not create an NTP/SNTP timing
loop by having two ONS 15454s reference each other).
• Date—If Use NTP/SNTP Server is not checked, type the current date (mm/dd/yyyy, for example,
September 24, 2002 is 09/24/2002).
Time—If Use NTP/SNTP Server is not checked, type the current time in the format hh:mm:ss, for
•
example, 11:24:58. The ONS 15454 uses a 24-hour clock, so 10:00 PM is entered as 22:00:00.

You can also position nodes manually on the network view map. Press Ctrl while you drag and
drop the node icon. To create the same network map visible for all ONS 15454 users, complete
the "NTP-A172 Create a Logical Network Map" procedure on page
Using an NTP or SNTP server ensures that all ONS 15454 network nodes use the same date
and time reference. The server synchronizes the node's time after power outages or software
upgrades.
