Chapter 6 Create Circuits and Low-Order Tunnels
NTP- D148 Create a Manual Cross-Connect for a G-Series or E-Series Card in Port-Mapped Mode
Step 4 If you want to change the default flow control settings, complete the “DLP-D353 Provision G-Series
Flow Control Watermarks” task on page 20-58.
Step 5 Click the Circuits tab and click Create.
Step 6 In the Circuit Creation dialog box, complete the following fields:
• Circuit Type—Choose VC_HO_PATH_CIRCUIT.
• Number of Circuits—Leave the default (1) unchanged.
• Auto-ranged—Unavailable.
Step 7 Click Next.
Step 8 Define the circuit attributes:
• 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:
–
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 19-26.
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.
Step 9 If the circuit will be routed on an SNCP ring, complete the “DLP-D218 Provision SNCP Ring Selectors
During Circuit Creation” task on page 19-17.
Step 10 Click Next.
Step 11 Provision the circuit source:
a. From the Node drop-down list, choose the circuit source node.
