2.8.3 2-Way Circuit Single Roll and Dual Roll Procedures
• ED-BULKROLL-<OCN_TYPE>
This command edits information about rolling traffic from one endpoint to another without
interrupting service. This command can use the CMDMDE option to force a valid signal. The only
parameter that can be edited is CMDMDE. The time slots cannot be edited. This commands supports
line-level rolling/bulk rolling and cannot be used for path-level rolling.
• ED-ROLL-<MOD_PATH>
This command edits information about rolling traffic from one endpoint to another without
interrupting service. This command can use the CMDMDE option to force a valid signal. The only
parameter that can be edited is CMDMDE. The time slots cannot be edited.
• ENT-BULKROLL-<OCN_TYPE>
This command enters information about rolling traffic from one endpoint to another without
interrupting service. This commands supports line level/bulk rolling and cannot be used for single
path-level rolling.
• ENT-ROLL-<MOD_PATH>
This command enters information about rolling traffic from one endpoint to another without
interrupting service. This command supports STS and VT path-level rolling only.
• RTRV-BULKROLL-<OCN_TYPE>
This command retrieves roll data parameters. This command supports line-level rolling/bulk rolling
and cannot be used for path-level rolling.
• RTRV-ROLL-<MOD_PATH>
This command retrieves roll data parameters.
2.8.3 2-Way Circuit Single Roll and Dual Roll Procedures
Single roll operation moves either the source or destination of a circuit to a new endpoint:
• Onto the same node or
• Onto a different node
In single roll operation, you only choose one roll point during the process.
Dual roll operation reroutes a segment between two roll points of a circuit. The new route can be:
• A new link (no circuit is required), or
• Another circuit (created before or during the bridge and roll process
• In dual roll operation, you choose two roll points during the process.
2.8.3.1 Create a 2-Way Circuit Single Roll or Dual Roll
To create a 2-way circuit single roll or dual roll, enter the ENT-ROLL-<MOD_PATH> command or the
ENT-BULKROLL-<OCN_TYPE> command depending on the type of roll you want to perform.
Input Formats:
• ENT-ROLL-<MOD_PATH>:[<TID>]:<FROM>,<TO>:<CTAG>:::RFROM=<RFROM>,
RTO=<RTO>,RMODE=<RMODE>,[CMDMDE=<CMDMDE>];
