Can you elaborate a little on this. The levels you are referring to are my downstream receive levels and I have no problems with that. I get my full 50Mbit Bandwith. The T3 errors relate to my Upstream channel.

There are a number of timers (T1 through T4). In this case, the T3 timer covers what is known as a "ranging request" sent to the CMTS (head end). After each unsuccessful attempt (i.e. no reply), the upstream power is increased until it reaches its maximum - whereupon a T3 timeout occurs.
When you are connected to the internet, then I would expect to see the upstream power level rather lower (let us know please).
To my mind, the modem is behaving properly but somewhere in the circuit on the other side of the modem, there is a problem. It starts with the coax cable needing to be properly screwed in both ends, goes on to noise anywhere on the line between your gaff and the CMTS.
So, if it's not a loose cable, an engineer it has to be and I suspect some street or cabinet work.

The installation Engineer already checked my path from outside the house to the modem and all was good. He raised a NETwork work request when he determined the Upstream power level was too high and a few days later they did some wk somewhere in the street dropping it by about 4dB. But I get these T3 timeouts pretetty bad. SO should that level be even lower?
