Figure 5-3 Setting Circuit Attributes For A Unidirectional Ds-1 Circuit - Cisco ONS 15327 Procedure Manual

NTP-B183 Create a Unidirectional DS-1 Circuit with Multiple Drops
Apply to drop ports—Check this check box if you want to apply the state chosen in the State field
•
to the circuit source and destination ports. CTC will apply the circuit state to the ports only if the
circuit bandwidth is the same as the port bandwidth or, if the port bandwidth is larger than the
circuit, the circuit must be the first circuit to use port. If not, a Warning dialog box displays the ports
where the circuit state could not be applied. If the check box is unchecked, CTC will not change the
state of the source and destination ports.
Note
• Create cross-connects only (TL1-like)—Check this check box if you want to create one or more
cross-connects to complete a signal path for TL1-generated circuits. If this check box is checked,
you cannot assign a name to the circuit. Also, VT tunnels and Ethergroup sources and destinations
are unavailable.
Inter-domain (UCP) SLA—If the circuit will travel on a unified control plane (UCP) channel, enter
•
the service level agreement number. Otherwise, leave the field set to zero.
Protected Drops—Check this check box if you want the circuit routed to protect drops only, that is,
•
to ONS 15327 cards that are in 1:1 or 1+1 protection. If you check this check box, CTC displays
only protected ports as source and destination choices.
