ABSTRACT:
A method of communicating between a phone line network which includes a plurality of devices coupled by a shared phone line medium, and a remote network. The method includes attaching a virtual local area network (VLAN) header to a data frame. The header's contents indicate that the data frame may be transmitted within a virtual network (VLAN) indicated by an identifier field of the VLAN header. The VLAN includes at least part of the phone line network and at least part of the remote network. The data frame is transmitted within the VLAN which includes a network connection between the network and the remote network.
