NTP-B135 Test Electrical Circuits
Set the circuit and circuit ports to the maintenance state (OOS-MT). Take note of the original state
Step 4
because you will return the circuit to that state later.
Click the circuit you want to test then choose Circuits > Set Circuit State from the Tools menu.
a.
On the Set Circuit State dialog box, choose OOS-MT from the Target State drop-down menu.
b.
Check the Apply to drop ports check box.
c.
Click Apply.
d.
Set the source and destination DS-1 port line length:
Step 5
a. In network view, double-click the source node.
b. Double-click the circuit source XTC card and click the Provisioning > Line tabs.
From the circuit source port Line Length drop-down menu choose the line length for the distance
c.
(in feet) between the DSX (if used) or circuit termination point and the source ONS 15327.
Click Apply.
d.
From the View menu choose Go to Network View.
e.
Repeat Steps
f.
Attach loopback cables to the circuit destination card.
Step 6
Verify the integrity of the loopback cable by looping the test set transmit (TX) connector to the test
a.
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
Attach the loopback cable to the port you are testing. Connect the transmit (TX) connector to the
b.
receive (RX) connector of the port.
Attach loopback cables to the circuit source node.
Step 7
Verify the integrity of loopback cable by looping the test set transmit (TX) connector to the test set
a.
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
Attach the loopback cable to the port you are testing. Connect the test set to the circuit source port:
b.
transmit (TX) port of the test set to the circuit receive (RX) port; test set receive (RX) port to the
circuit transmit (TX) port.
Configure the test set for the ONS 15327 card that is the source of the circuit you are testing:
Step 8
DS-1—If you are testing an unmuxed DS-1, you must have a DSX-1 panel or a direct DS-1 interface
•
into the ONS 15327. Set the test set for DS-1. For information about configuring your test set,
consult your test set user guide.
DS-3—If you are testing a clear channel DS-3, you must have a DSX-3 panel or a direct DS-3
•
interface into the ONS 15327. Set the test set for clear channel DS-3. For information about
configuring your test set, consult your test set user guide.
Step 9 Verify that the test set displays a clean signal. If a clean signal is not displayed, repeat Steps
8 to make sure the test set and cabling is configured correctly.
Step 10 Inject errors from the test set. Verify that the errors display at the source and destination nodes.
Step 11 Clear the PMs for the ports that you tested. See the
page 7-11
Step 12 Return the circuit and circuit ports to the state they were in at the beginning of the test:
Click the circuit you want to test then choose Circuits > Set Circuit State from the Tools menu.
