When I unplug my phone from the master socket my broadband modem does a full resync. Is this normal?
My phone is connected to the master socket via a filter and it is the filter that I am unplugging from the socket. My broadband modem is in an upstairs room connected to the back of the faceplate of the master socket by cabling that runs through the wall, then outside the house before re-entering the upstairs room. Only two wires are used connected to connections 2 and 5. The sync rate is only slightly higher when the phone is disconnected, 200/300k on a 13M sync.
