Method for improving the accessibility of a subscriber device of a broadband access and network.

A method for improving the accessibility of a subscriber to a device broadband access, comprising: establishing at least one identifier Route Virtual Local Area Network (VlanPI) and a VlanPI corresponding beacon; establishing a VLAN Circuit Identifier (VlanCI) and a VlanCI Tag corresponding to each access port device broadband access; wherein the method further comprises: dividing the access ports in groups and assign one of the at least one identifier VlanPI set to a group wherein the group is identified by the VlanPI attributed; determining a VlanCI corresponding to an access port, inserting the VlanCI Tag to identify the VlanCI into an Ethernet frame; determining the identifier VlanPI corresponding to the group to which belongs the access port, inserting the VlanPI to identify the VlanPI in the Ethernet frame and transmitting the Ethernet frame to an uplink device through a port uplink through device broadband access device that connects to the uplink; wherein the VlanPI is inserted into the Ethernet frame through the access device broadband device is connected with the uplink; before inserting the VlanPI in the Ethernet frame, whether the device broadband access is configured to transmit the VlanPI and the VlanCI Tag to uplink device and if the device broadband access is configured to transmit the beacon VlanPI and the VlanCI Tag to uplink device, insert the VlanPI in the Ethernet frame and transmitting the VlanPI and the VlanCI beacon device uplink and otherwise eliminate VlanCI Tag in the Ethernet frame, adding a mark 80
