Low-order tunnels allow low-order VC12 and VC3 circuits to pass through intermediary
Note
ONS 15454 SDH nodes without consuming low-order matrix resources on the cross-connect card. In
general, creating low-order tunnels is a good idea if you are creating many low-order circuits from the
same source and destination. Refer to the "Circuits and Tunnels" chapter in the Cisco ONS 15454 SDH
Reference Manual for more information.

The routing preferences for the new drop match those of the original circuit. However, you can
modify the following:
• If the original circuit was routed on a protected SNCP path, you can change the nodal diversity
options: Nodal Diversity Required, Nodal Diversity Desired, or Link Diversity Only. See
Step 13 for descriptions.
If the original circuit was not routed on a protected path, the Protection Channel Access option
