The invention relates to a method and system of service preparation of a residential network access device from one or more remote provisioning devices to prepare the residential network access device to receive a network service over a communications network. The method comprises the steps of receiving a line identifier indicating a physical line used by the residential network access device to connect to the communication network; transmitting an IP address from the one or more provisioning devices to the residential network access device for which the line identifier has been received, the IP address being a source address for the residential network access device, and transmitting software code portions to the IP address of the residential network access device, the software code portions being required for receiving the network service.
