11.18 11.18.2 Roll Status
Note CTC implements a roll mode at the circuit level. TL1 implements a roll mode at the
cross-connect level. If a single roll is performed, CTC and TL1 behave the same. If a dual
roll is performed, the roll mode specified in CTC might be different than the roll mode
retrieved in TL1. For example, if you select Automatic, CTC coordinates the two rolls to
minimize possible traffic hits by using the Manual mode behind the scenes. When both rolls
have a good signal, CTC signals the nodes to complete the roll.
– Automatic—When a valid signal is received on the new path, CTC completes the roll on the
node automatically. One-way source rolls are always automatic.
– Manual—You must complete a manual roll after a valid signal is received. One-way destination
rolls are always manual.
• Roll Path—The fixed point of the roll object.
• Roll From Circuit—The circuit that has connections that will no longer be used when the process is
complete.
• Roll From Path— The old path that is being rerouted.
• Roll To Path—The new path where the Roll From Path is rerouted.
• Complete—Completes a manual roll after a valid signal is received. You can do this when a manual
roll is in a ROLL_PENDING status and you have not yet completed the roll or have not cancelled
its sibling roll.
• Force Valid Signal—Forces a roll onto the Roll To Circuit destination without a valid signal.
Note If you choose Force Valid Signal, traffic on the circuit that is involved in the roll will be
dropped when the roll is completed.
• 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.
• Cancel—Cancels the roll process.
Note When the roll mode is Manual, cancelling a roll is only allowed before you click the
Complete button. When the roll mode is Auto, cancelling a roll is only allowed before a good
signal is detected by the node or before clicking the Force Valid Signal button.
