oscillator.
The GPS receiver is reporting
an error.
An error has been detected
on the specified remote
oscillator input signal.
The specified remote
oscillator input signal has been
lost.
An alarm indication signal
(AIS) has been received on

Recommended Action
Replace the system.
Troubleshoot the GPS, SPAN x, and
RO x error messages (check the cable,
source, etc.).
1. Check the view of the sky for
obstructions.
2. Raise the antenna elevation mask
setting, using the BTMONitor
Installation screen.
3. Check the cable connections
between the TimeSource 2500 Shelf
and the antenna.
4. If the error repeats, replace the
antenna.
5. If the error repeats, replace the cable.
Troubleshoot the specified remote
oscillator input (check signal frequency).
Verify the input frequency matches the
equipment configuration.
Troubleshoot the specified remote
oscillator input (check the cable,
connections, source).
Troubleshoot the specified T1 input
span signal (check the source).
Troubleshoot the specified T1 input
span signal (include checks for signal
frequency and jitter).
