Note
You can only reroute circuits in the DISCOVERED status. You cannot reroute circuits that are in the
ROLL_PENDING status.
11.19.3 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:

Description
A TL1 roll was initiated.
If a roll is created using TL1, a CTC user cannot complete or
Note
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.
