Rolls


(ONS 15600 only) The Rolls tab lists information about a rolled circuit before the roll process is complete.

Item

Description

Roll From Circuit

The circuit that has connections that will no longer be used once the roll process is complete.

Roll To Circuit

The circuit that will carry the traffic once the roll process is complete. The Roll To Circuit is the same as the Roll From Circuit if a single circuit is involved in a roll.

Roll State

The roll status:

  • ROLL_PENDING-Roll is awaiting completion or cancellation

  • ROLL_CANCELLED-Roll has been canceled

Roll Valid Signal

If the Roll Valid Signal status is true, a valid signal was found on the new port. If the Roll Valid Signal status is false, a valid signal was not found. It is not possible to get a Roll Valid Signal status of true for a one-way destination roll.

Roll Mode

The mode indicates whether the roll is automatic or manual. CTC implements roll mode at the cross-connect level, which mean it applies to connections within a single ONS 15600.

  • 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 Path

The path (STS) 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.

Finish

Completes the circuit processing of both manual and automatic rolls and changes the circuit status from ROLL_PENDING to DISCOVERED.

Cancel

Cancels the roll process. You can cancel a manual roll any time; you cannot cancel an automatic roll after a valid signal is found.

Help

Displays CTC context-sensitive help.
