11. Using the drop-down menus, select
"Rx 2/Interface/Signal" for the right
results display.
12. Verify the following:
• Rx 2 Summary LED is green
• Rx 2 Signal Present LED is green
• Rx 2 Frame Sync LED is green
• Rx 2 Rx Frequency (Hz) = 1544000  50 Hz
• BPVs = 0
• Rx 2 Frame Slips = 0
Troubleshooting tips:
•
If no Signal Present, check cables and verify you are in correct monitor point. Check the Rx Input
settings (DSX Mon or Bridge)
•
If no Frame Sync, check Framing setting (ESF or D4).
• If Rx Frequency ≠ 1544000  50 Hz, there is no clock on the circuit.
•
If BPVs present, there is an issue with either the signal level (Rx input settings, bad cable, etc.) or a
circuit problem between the test set and the last intelligent piece of equipment that is transmitting the
signal to the test set.
•
If CRC Errors, Framing Errors, or other errors present, check the Rx Input setting (DSX Mon or Bridge)
If errors persist, perform intrusive testing (BERT) to isolate the issue.
