Cisco ONS 15454 SDH Procedure Guide, R7.0

Chapter 6 Create Circuits and Low-Order Tunnels
NTP- D62 Test High-Order Circuits
Step 4
Complete the
“DLP-D230 Change a Circuit State” task on page 19-26
and set the circuit and circuit ports
to the Locked-enabled,maintenance 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 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.
Install the loopback cable on the port you are testing between the Tx and Rx connections.
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: 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 SDH card:
•
STM-1 cards—You will test a VC4 circuit on one of the STM-1 ports. Configure the test set for an
STM-1 port.
•
STM-4 cards—You will test either a VC4-4c or a multiplexed VC4-4. If you are testing a VC4-4c,
configure the test set for a VC4-4c. If you are testing a multiplexed VC4-4, configure the test set for
a multiplexed VC4-4 and choose the E3, DS3i-N-12, or E1 you will test. For information about
configuring your test set, consult your test set user guide.
•
STM-16 cards—You will test either a VC4-16c or a multiplexed VC4-16. If you are testing a
VC4-16c, configure the test set for a VC4-16c. If you are testing a multiplexed VC4-16, configure
the test set for a multiplexed VC4-16 and choose the E3, DS3i-N-12, or E1 you will test. For
information about configuring your test set, consult your test set user guide.
•
STM-64 cards—You will test a VC4-64c or a multiplexed VC4-64. If you are testing a VC4-64c,
configure the test set for a VC4-64c. If you are testing a multiplexed VC4-64, configure the test set
for a multiplexed VC4-64 and choose the E3, DS3i-N-12, or E1 you will test. For information about
configuring your test set, consult your test set user guide.
Step 8
Verify that the test set shows a clean signal. If a clean signal does not appear, repeat Steps
through
to make sure you have configured the test set and cabling correctly.
Step 9
Inject errors from the test set. Verify that the errors appear at the source and destination nodes.
Step 10
Clear the PM counts for the ports that you tested. See the
“DLP-D459 Clear Selected PM Counts” task
for instructions.
Step 11
Perform protection switch testing appropriate to the SDH topology:
•
For SNCP rings, see the
“DLP-D94 SNCP Protection Switching Test” task on page 17-91
•
For MS-SPRings see the
“DLP-D91 MS-SPRing Switch Test” task on page 17-84
.
Step 12
Perform a BERT for 12 hours or follow your site requirements for length of time. For information about
configuring your test set for BERT, see your test set user guide.
Step 13
After the BERT is complete, print the results or save them to a disk for future reference. For information
about printing or saving test results, see your test set user guide.
Step 14
Complete the
“DLP-D230 Change a Circuit State” task on page 19-26
and change the circuit and circuit
ports from Unlocked,maintenance to their previous service states.
