NTP-A167 Create an STS Test Circuit around the Ring
NTP-A167 Create an STS Test Circuit around the Ring
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 circuits you want to create. The default is 1.
• Auto-ranged—Applies to automatically routed circuits only. If you entered more than 1 in the
Number of Circuits field, uncheck this box. (The box is unavailable if only one circuit is entered in
Number of Circuits.)
Step 6 Click Next.
Step 7 Define 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 circuit size. Choices are 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:
–
IS—Puts the circuit cross-connects in the IS-NR service state.
–
OOS,DSBLD—Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is
not passed on the circuit.
–
IS,AINS—Puts the circuit cross-connects in the OOS-AU,AINS service state and suppresses
alarms and conditions. When the connections receive a valid signal, the service state
automatically changes to IS-NR.
Purpose This procedure creates an STS test circuit that routes traffic around a ring
with the source and destination located on different ports of the same node.
