Description
|
Node
|
Sets the circuit drop destination node.
|
Slot
|
Sets the circuit drop slot.
|
Port
|
Sets the circuit drop port.
|
STS
|
Sets the circuit drop specific synchronous transport signal (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 Out-of-Service and
Management, Disabled (OOS-MA,DSBLD) service state. Traffic is not
passed on the circuit.
IS-Puts the circuit cross-connects in the In-Service, Normal (IS-NR)
service state.
IS,AINS-Puts the circuit cross-connects in the Out-of-Service and
Autonomous, Automatic In-Service (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 Out-of-Service and
Management, Maintenance (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-(Virtual concatenated [VCAT] link capacity adjustment
scheme [LCAS] circuits only) Puts the circuit cross-connects in the
Out-of-Service and Management, Out-of-Group (OOS-MA,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.
|
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:
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 unidirectional path switched ring (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 bidirectional line switched ring (BLSR), clicking this check box routes the circuit drop on a BLSR protection channel access (PCA) path. Circuits routed on PCAs are unprotected.
|
Finish
|
Creates the circuit drop.
|
Cancel
|
Cancels circuit drop creation.
