High level of distortion in TDE due
to excessive multipath activity.
Check path for interference.
More delay in system than elastic buffers on DS1 I/O Inter-
face can correct.
1. Isolate the delay to local or farend. Delay in the farend XMTR is a possible cause in frequency
diversity configurations. Is the farend radio frequency diversity?
Yes, go to 2.
No, delay is probably a local problem. Go to 3.
2. Verify there are no farend XMTR alarms. Troubleshoot and clear farend XMTR alarms first.
3. Check/repair waveguide/path.
4. Isolate delay to A-side or B-side I/O Interface. On local controller front panel, observe I/O ALM
indicators. The A or B I/O ALM will be lit for the side with the excessive delay.
5. Remove/replace RCVR on alarmed side.
6. Remove/replace I/O Interface module on alarmed side.
