Create Circuits and Low-Order Tunnels
If you want to change the default flow control settings, complete the
Step 4
Flow Control Watermarks" task on page
Step 5
Click the Circuits tab and click Create.
In the Circuit Creation dialog box, complete the following fields:
Step 6
Circuit Type—Choose VC_HO_PATH_CIRCUIT.
•
Number of Circuits—Leave the default (1) unchanged.
•
Auto-ranged—Unavailable.
•
Click Next.
Step 7
Define the circuit attributes:
Step 8
Name—Assign a name to the source cross-connect. The name can be alphanumeric and up to
•
48 characters (including spaces). Circuit names should be 44 characters or less if you want the
ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the
source cross-connect.
•
Size—Choose the size of the circuit that will be carried by the cross-connect. Valid sizes for a
G-Series circuit are VC4, VC4-2c, VC4-3c, VC4-4c, VC4-8c, and VC4-16c. For an E-Series circuit
in port-mapped mode, valid sizes are VC4, VC4-2c, and VC4-4c.
Bidirectional—Leave the default (checked) unchanged.
•
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 you check this box, low-order
tunnels and Ethergroup sources and destinations are unavailable.
State—Choose the administrative state to apply to all of the cross-connects in a circuit:
•
–
–
–
–
For additional information about circuit service states, refer to the "Circuits and Tunnels" chapter
in the Cisco ONS 15454 SDH Reference Manual.
Apply to drop ports—Uncheck this box.
•
Protected Drops—Leave the default (unchecked) unchanged.
•
If the circuit will be routed on an SNCP ring, complete the

Step 11
From the Node drop-down list, choose the circuit source node.

NTP- D148 Create a Manual Cross-Connect for a G-Series or E-Series Card in Port-Mapped Mode
Unlocked—Puts the circuit cross-connects in the Unlocked-enabled service state.
Locked,disabled—Puts the circuit cross-connects in the Locked-enabled,disabled service state.
Traffic is not passed on the circuit.
Unlocked,automaticInService—Puts the circuit cross-connects in the
Unlocked-disabled,automaticInService service state and suppresses alarms and conditions.
When the connections receive a valid signal, the service state automatically changes to
Unlocked-enabled.
Locked,maintenance—Puts the circuit cross-connects in the Locked-enabled,maintenance
service state. The maintenance state does not interrupt traffic flow; it suppresses alarms and
conditions and allows loopbacks to be performed on the circuit. Use Locked,maintenance for
circuit testing or to suppress circuit alarms temporarily. Change the administrative state to
Unlocked; Unlocked,automaticInService; or Locked,disabled when testing is complete. See the
"DLP-D230 Change a Circuit State" task on page
