If you have four terminals that have previously worked normally, and all of them are suddenly and at the same time now fast flashing green then maybe there is uplink interference on your return link frequency so that no site can communicate to the hub.
The same symptom at all sites suggests a common cause such as satellite interference or hub problem. A symptom at one site suggests a local fault. But, don't rule out the possibility that all sites may have deteriorated and failed progressively at different times due to corrosion caused by moisture inside the transmit BUC cables.
Do all sites still have good receive quality ? What is the QPSKBER at each site ? (0.00001 is very good, 0.01 is very poor)
This is all speculation, so please get back to BW and keep them up to date on the status of each site and they can check them out from the hub end.
Best regards, Eric.
