Cancel the Circuit Creation and Start Over
Step 1 Cancel the circuit creation:
a. Click Cancel.
b. Click Back until you return to the initial circuit creation window.
Step 2 Check the list of available ports. The previously selected port no longer appears in the available list
because it is now part of a provisioned circuit.
Step 3 Select a different available port and begin the circuit creation process.

Table 1-18 “Path in Use” Error When Creating a Circuit
Possible Problem Solution
Another user has
already selected the
same source port to
create another circuit
CTC does not remove a card or port from the available list until a circuit is
completely provisioned. If two users simultaneously select the same source
port to create a circuit, the first user to complete circuit provisioning gets use
of the port. The other user gets the “Path in Use” error.
See the “Cancel the Circuit Creation and Start Over” procedure on
