Note Create a Roll To Circuit before rolling a circuit with the source on Node 3 and the destination on Node 4.
A dual roll involves two cross-connects. It allows you to reroute intermediate segments of a circuit, but
keep the original source and destination. If the new segments require new cross-connects, use the Bridge
and Roll wizard or create a new circuit and then perform a roll.
Only single rolls can be performed using TL1. Dual rolls require the network-level view that only CTC
Caution
or CTM provide.
