Chapter 5 Turn Up a Network
NTP- D341 Two-Fiber MS-SPRing Acceptance Test
•
For VC11 circuits, complete the
“NTP-D334 Create an Automatically Routed Low-Order VC11
Circuit” procedure on page 6-7
. When you set the circuit state, choose
Unlocked
and check the
Apply to drop ports
check box.
Step 8
Configure the test set for the test circuit type you created:
•
VC4 or VC4-nc—If you are testing a VC4 circuit or a VC4-nc circuit on an STM-N card, you must
have a direct optical interface into the ONS 15454 SDH. Set the test set for STM-N. For information
about configuring your test set, consult your test set user guide.
•
VC3—If you are testing a clear channel E3/DS3I, you must have a patch panel or a direct E3/DS3I
interface into the ONS 15454 SDH. Set the test set for clear channel E3/DS3I. For information about
configuring your test set, consult your test set user guide.
•
VC12—If you are testing an E1, you must have a patch panel or a direct E1 interface to the
ONS 15454 SDH. Set the test set for E1. For information about configuring your test set, consult
your test set user guide.
•
VC11—If you are testing a VC11 circuit on an STM-N or MRC-12 card, you must have a direct
optical interface to the ONS 15454 SDH. Set the test set for STM-N. For information about
configuring your test set, consult your test set user guide.
Step 9
Verify the integrity of all patch cables that will be used in this test by connecting 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 the next step.
Step 10
Create a physical loopback at the circuit destination card: attach one end of a patch cable to the
destination port’s transmit (Tx) connector; attach the other end to the port’s receive (Rx) connector.
Step 11
At the circuit source card:
a.
Connect the transmit (Tx) connector of the test set to the circuit receive (Rx) connector.
b.
Connect the test set receive (Rx) connector to the circuit transmit (Tx) connector.
Step 12
Verify that the test set shows a clean signal. If a clean signal is not present, repeat Steps
through
make sure the test set and cabling are configured correctly.
Step 13
Inject BIT errors from the test set. Verify that the errors appear at the test set, verifying a complete
end-to-end circuit.
Step 14
Complete the
“DLP-D254 TCC2/TCC2P Card Active/Standby Switch Test” task on page 19-59
.
Step 15
Complete the
“DLP-D255 Cross-Connect Card Side Switch Test” task on page 19-60
Although a service interruption under 60 ms may occur, the test circuit should continue to work before,
during, and after the switches. If the circuit stops working, do not continue. Contact your next level of
support.
Step 16
Complete the
“DLP-D91 MS-SPRing Switch Test” task on page 17-84
at Node 1.
Step 17
Set up and complete a BER test on the test circuit. Use the existing configuration and follow your site
requirements for length of time. Record the test results and configuration.
Step 18
Complete the
“DLP-D27 Delete Circuits” task on page 17-21
for the test circuit.
Step 19
Repeating Steps
through
for Nodes 2 and higher, work your way around the MS-SPRing, testing
each node and span in the ring. Work your way around the MS-SPRing creating test circuits between
every two consecutive nodes.
Step 20
After you test the entire ring, remove any loopbacks and test sets from the nodes.
Step 21
If a node fails any test, repeat the test while verifying correct setup and configuration. If the test fails
again, refer to the next level of support.
