Chapter 6 Create Circuits and Low-Order Tunnels
NTP- D135 Test Low-Order Circuits
NTP-D135 Test Low-Order Circuits
Step 1
Complete the
“DLP-D60 Log into CTC” task on page 17-49
at an ONS 15454 SDH on the network
where you will test the circuit. If you are already logged in, continue with Step 2.
Step 2
From the View menu, choose
Go to Network View
.
Step 3
Click the
Circuit
tab.
Step 4
Complete the
“DLP-D230 Change a Circuit State” task on page 19-26
and set the circuit ports to the
Locked-enabled,maintenance service state. Take note of the original state because you will return the
circuit to that state later.
Step 5
Attach loopback cables to the circuit destination card.
a.
Verify the integrity of the loopback cable by looping the test set transmit (Tx) connector to the test
set receive (Rx) connector. 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 before going to Step
b.
Attach the loopback cable to the port you are testing. Connect the Tx connector to the Rx connector
of the port.
Purpose
This procedure tests low-order VC11, VC12, and VC3 circuits.
Tools/Equipment
A test set and all appropriate cables
Prerequisite Procedures
This procedure assumes that you completed facility loopback tests on the
fibers and cables from the source and destination ONS 15454 SDHs to the
digital signal cross-connect (DSX), and that you created a circuit using one
of the following procedures:
NTP-D334 Create an Automatically Routed Low-Order VC11 Circuit,
page 6-7
NTP-D335 Create a Manually Routed Low-Order VC11 Circuit, page 6-12
NTP-D336 Create a Unidirectional Low-Order VC11 Circuit with
Multiple Drops, page 6-15
NTP-D81 Create an Automatically Routed Low-Order VC12 Circuit, page
6-19
NTP-D82 Create a Manually Routed Low-Order VC12 Circuit, page 6-24
NTP-D83 Create a Unidirectional Low-Order VC12 Circuit with Multiple
Drops, page 6-27
NTP-D54 Create an Automatically Routed Low-Order VC3 Circuit, page
6-31
NTP-D55 Create a Manually Routed Low-Order VC3 Circuit, page 6-35
NTP-D56 Create a Unidirectional Low-Order VC3 Circuit with Multiple
Drops, page 6-38
