Hello VM,

I seem to have an intermittent connection with Several T3 timeouts on the upstream and several loss of synchronisation.

I have had a technician come out to me and he checks the connection and says everything is fine and then leaves, I have attached my logs below , I draw your attention to the T3 Timeouts on all the upstream channels and the Loss of synchronisation errors.

is there something you can spot that is wrong with my connection?
