Protected Drops—Check this box if you want the circuit routed on protected drops only, that is, to
ONS 15454 cards that are in 1:1, 1:N, 1+1, or optimized 1+1 protection. If you check this box, CTC
displays only protected cards and ports as source and destination choices.

Step 10 Complete the “DLP-A95 Provision a DS-1 Circuit Source and Destination” task on page 17-96 .
Step 11
In the Circuit Routing Preferences area ( Figure 6-2 ), choose Route Automatically . Two options are
available; choose either, both, or none based on your preferences.
• Using Required Nodes/Spans—Check this check box if you want to specify nodes and spans to
include or exclude in the CTC-generated circuit route.
Including nodes and spans for a circuit ensures that those nodes and spans are in the working path
of the circuit (but not the protect path). Excluding nodes and spans ensures that the nodes and spans
are not in the working or protect path of the circuit.
• Review Route Before Creation—Check this check box if you want to review and edit the circuit
route before the circuit is created.
