Step 1 Display the command prompt:

Step 3 If the workstation has connectivity to the ONS 15454 SDH, the ping is successful and displays a reply
from the IP address. If the workstation does not have connectivity, a “Request timed out” message
displays.
Step 4 If the ping is successful, an active TCP/IP connection exists. Restart CTC.
Step 5 If the ping is not successful, and the workstation connects to the ONS 15454 SDH through a LAN, check
that the workstation’s IP address is on the same subnet as the ONS node.

Possible Problem Solution
A lost connection
between the PC and the
ONS 1554.
Use a standard ping command to verify the TCP/IP connection between the
PC and the ONS 15454 TCC-I card. A ping command will work if the PC
connects directly to the TCC-I card or uses a LAN to access the TCC-I card.
