Define New Drop
Use the Define New Drop dialog box to create new drops for unidirectional circuits and (ONS 15454 only) E-Series Ethernet circuits.
 
Item
Description
Node
Sets the circuit drop destination node.
Slot
Sets the circuit drop slot.
Port
Sets the circuit drop port.
QinQ Settings
(SVLAN circuit only) Displays the QinQ settings page.
STS
Sets the circuit drop specific STS.
Target Circuit Admin State
Lists the administrative states. An administrative state puts the circuit cross-connects into the related service state if network conditions allow:
 •
No Change—The circuit state will not be changed.
 •
OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit.
 •
IS—Puts the circuit cross-connects in the IS-NR service state.
 •
IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state. Alarms and conditions are suppressed. When the connections receive a valid signal, the service state automatically changes to IS-NR.
 •
OOS,MT—Puts the circuit cross-connects in the OOS-MA,MT service state. The OOS-MA,MT service state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use the OOS,MT administrative state for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete.
 •
OOS,OOG—(VCAT LCAS circuits only) Puts the circuit cross-connects in the OOS-MA,MT & OOG service state. The OOS,OOG administrative state is used to place a VCAT member circuit out of the group and to stop sending traffic. OOS,OOG only applies to the cross-connect on the end node where the VCAT resides.
For additional state information, see States.
Apply to drop ports
Applies the state chosen in the Target Circuit Admin State field to the circuit drop port. CTC applies the circuit state to the port only in the following cases:
 •
The circuit bandwidth is the same as the port bandwidth.
 •
The port bandwidth is larger than the circuit and the circuit is the first circuit to use the drop port.
A Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.
Route Automatically
If checked, CTC routes the circuit automatically based on the parameters that you specify on this pane.
Using Required Nodes/Spans
If checked, CTC displays a pane allowing you to choose nodes and spans to include in the automatically routed circuit path before circuit completion.
Review Route Before Creation
If checked, CTC allows you to review and modify the circuit route before circuit creation.
Fully Protected Path
If checked, CTC creates a fully protected circuit route based on the path diversity option you choose. Fully protected paths might or might not have UPSR path segments (with primary and alternate paths), and the path diversity options apply only to UPSR path segments, if any exist.
Nodal Diversity Required
Ensures that the primary and alternate paths within UPSR portions of the complete circuit drop path are nodally diverse.
Nodal Diversity Desired
Specifies that node diversity is preferred, but if node diversity is not possible, CTC creates fiber-diverse paths for the UPSR portion of the complete circuit drop path.
Link Diversity Only
Specifies that only fiber-diverse primary and alternate paths for UPSR portions of the complete circuit drop path are needed. The paths might be node-diverse, but CTC does not check for node diversity.
Protection Channel Access
If Fully Protected Path is not checked and the circuit is routed on a BLSR, clicking this check box routes the circuit drop on a BLSR PCA path. Circuits routed on PCAs are unprotected.
Finish
Creates the circuit drop.
Cancel
Cancels circuit drop creation.

Displays context-sensitive help.
