Presumably your cat6 cables terminate on a series of RJ45 sockets in the service room. You will need to site the hub in the same room and connect the individual LAN ports to the required RJ 45 socket with Ethernet patch cords. If you require more locations than ports on the hub, you will need to use an Ethernet switch. If you are getting FTTP, Openreach will supply an ONT (optical modem) which connects to your hub WAN port. If you are getting FTTC, Openreach will divide master socket which connects to the DSL port on the hub.
