11.17.3 Single and Dual Rolls
Circuits have an additional layer of roll types: single and dual. A single roll on a circuit is a roll on one
of its cross-connects. Use a single roll to:

Finish—Completes the circuit processing of both manual and automatic rolls and changes the circuit
status from ROLL_PENDING to DISCOVERED. After a roll, the Finish button also removes any
cross-connects that are no longer used from the Roll From Circuit field. The roll process ends when
you finish the roll.
Cancel—Cancels the roll process. When the roll mode is Manual, cancel roll is only allowed before
you click the Complete button. When the roll mode is Auto, cancel roll is only allowed before a good
signal is detected by the node or before you click the Force Valid Signal button.

for a list of circuit statuses.) You cannot reroute circuits that are in the

Roll a segment of the circuit onto another chosen circuit
results in a new destination or a new source.

Description
The roll is awaiting completion or cancellation.
The roll is complete. Click the Finish button.
The roll has been canceled.
A TL1 roll was initiated.
If a roll is created using TL1, a CTC user cannot complete or

cancel the roll. Also, if a roll is created using CTC, a TL1 user
cannot complete or cancel the roll. You must use the same
interface to complete or change a roll.
This state appears when the underlying circuit becomes incomplete. To
correct this state, you must fix the underlying circuit problem before the
roll state will change.
For example, a circuit traveling on Nodes A, B, and C can become
INCOMPLETE if Node B is rebooted. The cross-connect information is
lost on Node B during a reboot. The Roll State on Nodes A and C will
change to INCOMPLETE.
