Chapter 6 Create Circuits and VT Tunnels
NTP-A257 Create an Automatically Routed OC-N Circuit
Stop. You have completed this procedure.
NTP-A257 Create an Automatically Routed OC-N Circuit
Step 1 Complete the “DLP-A60 Log into CTC” task on page 17-66 at the node 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-A314 Assign a Name to a Port” task on page 20-8. 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 STS.
• Number of Circuits—Enter the number of OC-N circuits you want to create. The default is 1. If you
are creating multiple circuits with the same source and destination, you can use auto-ranging to
create the circuits automatically.
• Auto-ranged—This check box is automatically selected when you enter more than 1 in the
Number of Circuits field. Leave this check box selected if you are creating multiple OC-N circuits
with the same source and destination and you want CTC to create the circuits automatically.
Uncheck the box if you do not want CTC to create the circuits automatically.
Step 6 Click Next.
Step 7 Define the circuit attributes (Figure 6-9 on page 6-39):
• 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 OC-N circuit size: STS-1, STS-3c, STS-6c, STS-9c, STS-12c, STS-18c,
STS-24c, STS-36c, STS-48c, or STS-192c.
• Bidirectional—Leave checked for this circuit (default).
• Create cross-connects only (TL1-like)—Check this box if you want to create one or more
cross-connects to complete a signal path for TL1-generated circuits. Also, VT tunnels and
Ethergroup sources and destinations are unavailable.
• State—Choose the administrative state to apply to all of the cross-connects in a circuit:
Purpose This procedure creates an automatically routed bidirectional or
unidirectional OC-N circuit, including STS-1 and concatenated STS-3c,
STS-6c, STS-9c, STS-12c, STS-18c, STS-24c, STS-36c, STS-48c, or
STS-192c speeds.
