Chapter 5 Create Circuits and VC Low-order Path Tunnels
Before You Begin
Step 1
Complete the “DLP-H29 Log into CTC” task on page 16-43 at a node on the network where you will
create the circuit. If you are already logged in, continue with Step 2 .
Step 2 If you want to assign a name to the tunnel source and destination ports before you create the circuit,
complete the
“DLP-H56 Assign a Name to a Port” task on page 16-75 . If not, continue with Step 3 .
Step 3
From the View menu, choose Go to Network View .
Step 4 In the Circuit Creation dialog box, complete the following fields:
•
Circuit Type—Choose VC high-order path or VC low-order path .
• Number of Circuits—Enter the number of circuits that you want to create. The default is 1.
•
Auto-ranged—This box is automatically selected if you enter more than 1 in the Number of Circuits
field. Uncheck the box if you want to create multiple circuits at one go. For example, if you specify
the number of circuits as 3, the Circuit Creation dialog box appears after the first circuit is created
so you can create the remaining circuits.
Note
If specify the number of circuits as more than 1 and if the auto-ranged check box is selected, the
Route Automatically check box in the Circuit Routing Preferences area is automatically
checked; this prevents you from creating an overlay ring circuit.
Step 5
Click Next .
Step 6
Define the circuit attributes:
•
Name—Assign a name to the circuit. 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 circuit.
• Size—Choose the optical circuit size. If you are creating an VC high-order path circuit, the choices
are VC3, VC4, VC4-2c, VC4-3c, or VC4-4c. If you are creating a VC low-order path circuit, Size
displays VC-12. You cannot change it.
•
Bidirectional—Leave the default (checked) for this circuit.
• 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. Also, VC low-order path
tunnels and Ethergroup sources and destinations are unavailable.
•
Diagnostic—Leave the default (unchecked).
•
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, outOfGroup —Puts the circuit cross-connects in the locked-enabled,disabled service
state. Traffic is not passed on the circuit.
–
Automatic In Service —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; Automatic In Service; or locked, outOfGroup when testing is complete. See the
“DLP-H111 Change a Circuit Service State” task on page 17-15 .
