Chapter 4 Turn Up a 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 characters.
Contact—(Optional) Type the name of the node contact person and the phone number, up to
•
255 characters.
• Latitude—(Optional) Enter the node latitude: N (North) or S (South), degrees, and minutes.
• Longitude—(Optional) Enter the node longitude: E (East) or W (West), degrees, and minutes.
Tip
CTC uses the latitude and longitude to position ONS 15454 SDH 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 SDH
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
"DLP-D112 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 SDH SOCKS proxy server, (see
the
reference the gateway ONS 15454 SDH for NTP/SNTP timing. For more information about the
SOCKS proxy server feature, refer to the "CTC Network Connectivity" chapter in the
Cisco ONS 15454 SDH Reference Manual.
If you reference another ONS 15454 SDH for the NTP/SNTP server, make sure the second
Caution
ONS 15454 SDH references an NTP/SNTP server and not the first ONS 15454 SDH (that is, do not
create an NTP/SNTP timing loop by having two ONS 15454 SDH nodes reference each other).
Date—If Use NTP/SNTP Server is not selected, type the current date in the format mm/dd/yyyy, for
•
example, September 24, 2004 is 09/24/2004.
• Time—If Use NTP/SNTP Server is not selected, type the current time in the format hh:mm:ss, for
example, 11:24:58. The ONS 15454 SDH 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 then drag and drop
the node icon. To create a logical network map for all ONS 15454 SDH users, complete the
"NTP-D172 Create a Logical Network Map" procedure on page
Using an NTP or SNTP server ensures that all ONS 15454 SDH network nodes use the same
date and time reference. The server synchronizes the node's time after power outages or
software upgrades.
