After posting the latest info i rang tp help line and was really surprised at his honesty. I asked if the tp units would send the full 800 mb from the ONT and smart hub all the way round my home and he surprised me when he said . He said their is a 30% loss and sometimes more as the signals travel around the wiring and he worked out i would get less than i am getting now. They make a bigger unit the pg2400 but he said after signal loss i would not be much better off. Thank you for being honest but i wont be buying one.
With regards to DV i showed the engineer the adapter i had ready for when i needed to use it and he said just plug your phone into the back of your smart hub , it takes about 6 hours for the system to except incoming calls. He also said on digital voice calls you need to use the dialling code as well as the rest of the phone number
