11.16.2 Roll Status
• Force Valid Signal—Forces a roll onto the Roll To Circuit destination without a valid signal. 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. 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.
11.16.2 Roll Status
Table 11-15 lists the roll statuses. You can only reroute circuits that have a DISCOVERED status. (See
Table 11-2 on page 11-6 for a list of circuit statuses.) You cannot reroute circuits that are in the
ROLL_PENDING status.
11.16.3 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:
• Change either the source or destination of a selected circuit (Figure 11-14 and Figure 11-15,
respectively).
• Roll a segment of the circuit onto another chosen circuit (Figure 11-16 on page 11-31). This roll also
results in a new destination or a new source.
In Figure 11-14, you can select any available VC4 on Node 1 for a new source.
Table 11-15 Roll Statuses
State Description
ROLL_PENDING The roll is awaiting completion or cancellation.
ROLL_COMPLETED The roll is complete. Click the Finish button.
ROLL_CANCELLED The roll has been canceled.
TL1_ROLL A TL1 roll was initiated.
Note 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.
INCOMPLETE 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.
