Abstract: The invention relates to a method and a system adapting broadband access equipment to query customer premises switches of a medium access control address located on its physical interface to the customer premises equipment. All customer premises switches are receiving a first request, hereby conducting a lookup in their medium access control address table for the medium access control address. When finding a matching table entry, the customer premises switch housing the medium access control address (MAC) in its table replies with a port name of the specific downlink port, thus identifying the port location of the accessing customer premises equipment and automatically providing a CPE with the correct service depending on which port the CPE is connected to. The customer premises switch is periodically scanning the medium access control address table, continuously transmitting table entries to broadband access equipment.

Abstract: The invention relates to a method and a system adapting broadband access equipment (20) to query customer premises switches (16, 18) of a medium access control address located on its physical interface to the customer premises equipment (10, 22). All customer premises switches (16, 18) are receiving a first request, hereby conducting a lookup in their medium access control address table for the medium access control address. When finding a matching table entry, the customer premises switch (16, 18) housing the medium access control address (MAC) in its table replies with a port name of the specific downlink port, thus identifying the port location of the accessing customer premises equipment (22) and automatically providing a CPE with the correct service depending on which port the CPE is connected to. The customer premises switch (16, 18) is periodically scanning the medium access control address table, continuously transmitting table entries to broadband access equipment (20).
