Chapter 5 Create Circuits and VC Low-order Path Tunnels
Before You Begin
NTP-H42 Create a Unidirectional DS-3 or E3 Circuit with
Multiple Drops
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 circuit 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
Click the Circuits tab, then click Create .
Step 5 In the Circuit Creation dialog box, complete the following fields:
•
Circuit Type—Choose VC high-order path (both DS-3 and E3) or VC low-order path (E3 only) .
•
Number of Circuits—Leave the default unchanged (1).
•
Auto-ranged—Unavailable when the Number of Circuits is 1.
Step 6 Click Next .
Step 7
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—If you are creating a VC high-order path circuit, choose VC3 . If you are creating a VC
low-order path circuit, Size displays VC-12 and cannot be changed.
•
Bidirectional—Uncheck 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.
Purpose This procedure creates a unidirectional DS-3 or E3 circuit with multiple
drops.
