I have four links that are all running connectorized PTP 650s. All of them run great and have the expected bandwidth and such for our design and system.
However, I have noticed that they seem to "reset" themselves at times, almost like a watchdog timer or keep-alive feature which has been troublesome. One of the links runs to a single connection site which runs the southern area of our radio network, so when it does this it brings down the whole area for a few minutes.
Is there a way to disable this? I don't think it's a hardware issue, as all four of them do this, and one was bought about six months before the other three.
