Perform OC-3c (STS-3c) Transmission Test
1.
NOTE:
Ensure that the OC-3c feature has been enabled .
NOTE:
This procedure may be used to perform OC-3c transmission tests in the
mux (toward the fiber) direction. When this procedure is being used to
perform end-to-end OC-3c tests. It is assumed that the complete
end-to-end system has already been tested and that only the OC-3c
signal is being tested at this time. Transmission tests in the mux direction
may be local or end-to-end tests. (see Figure 1).
NOTE:
This test is performed with a SONET test set.
NOTE:
When this procedure is used to do end-to-end tests, one DDM-2000 shelf
will be referred to as the near end and the other shelf as the far end.
These designations are arbitrary; either shelf can be the near-end ot the
far-end shelf.
See Figure 1. If local tests are being preformed, the fiber loopback at the
near-end 22D-U/22G-U/22G2-U/22G3-U/22G4-U OLIU must be in place. If
end-to-end tests are being performed, at the far-end LGX cross-connection
associated with the DDM-2000 FiberReach being tested, connect a patch cord
from the OUT jack to the IN jack for the OC-3c signal to be tested.
2. At the cross-connection associated with the near-end DDM-2000 FiberReach,
connect the SONET test set to the IN and OUT jacks associated with the
circuit under test.
3. Use the SONET test set to test for error-free transmission.
4. Was the test successful (error free)?
If YES, continue with Step 5.
If NO, proceed to Step 14.
