NTP-A185 Create a Manually Routed DS-3 Circuit
NTP-A185 Create a Manually Routed DS-3 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 3.
Step 2 If you want to assign a name to the circuit 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 4.
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. STS cross-connects will carry the DS-3 circuit across the ONS 15454
network.
• Number of Circuits—Enter the number of DS-3 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 the circuit attributes (Figure 6-3 on page 6-15):
• 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 this field blank, CTC assigns a default name to the circuit.
• Size—Choose STS-1. For circuits on the DS3i-N-12 card, choose STS-3c. This sets a port group for
ports 1, 4, 7, and 10 using 3 ports at any given time.
• Bidirectional—Leave this field checked (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 a DS-3 circuit and allows you to provision the
circuit route.
