NTP-A62 Test OC-N Circuits
NTP-A62 Test OC-N Circuits
Step 1 Complete the “DLP-A60 Log into CTC” task on page 17-66 at the node where you will create the circuit.
Step 2 From the View menu, choose Go to Network View.
Step 3 Click the Circuits tab.
Step 4 Complete the “DLP-A230 Change a Circuit Service State” task on page 19-19 to set the circuit and
circuit ports to the OOS-MA,MT service state.
Step 5 Set up the patch cable at the destination node:
a. Test the patch cable by connecting one end to the test set transmit (Tx) port and the other end to the
test receive (Rx) port. If the test set does not run error-free, check the cable for damage and check
the test set to make sure it is set up correctly.
b. Install the loopback cable on the port you are testing. Connect the Tx connector to the Rx connector
of the port being tested.
Step 6 Set up the loopback cable at the source node:
a. Test the loopback cable by connecting one end to the test set Tx port and the other end to the test Rx
port. If the test set does not run error-free, check the cable for damage and check the test set to make
sure it is set up correctly.
b. At the source node, attach the loopback cable to the port you are testing. Connect the test set to the
circuit source port. Connect the Tx port of the test set to the circuit Rx port, and the test set Rx port
to the circuit Tx port.
Step 7 Configure the test set for the source ONS 15454 card:
• OC-3 cards—You will test either an OC-3c or a multiplexed OC-3. If you are testing an OC-3c,
configure the test set for an OC-3c. If you are testing a multiplexed OC-3, configure the test set for
a multiplexed OC-3 and choose the DS-3 and/or DS-1 you will test. For information about
configuring your test set, consult your test set user guide.
• OC-12 cards—You will test either an OC-12c or a multiplexed OC-12. If you are testing an OC-12c,
configure the test set for an OC-12c. If you are testing a multiplexed OC-12, configure the test set
for a multiplexed OC-12 and choose the DS-3 and/or DS-1 you will test. For information about
configuring your test set, consult your test set user guide.
Purpose This procedure tests an OC-N circuit.
Tools/Equipment Test set capable of OC-N speeds, appropriate fibers, and attenuators
Prerequisite Procedures This procedure assumes you completed facility loopback tests to test the
fibers and cables from the source and destination ONS 15454s to the fiber
distribution panel or the DSX and one of following circuit procedures:
NTP-A257 Create an Automatically Routed OC-N Circuit, page 6-38
NTP-A295 Create a Manually Routed OC-N Circuit, page 6-43
NTP-A314 Create a Unidirectional OC-N Circuit with Multiple Drops,
page 6-46
