Abstract:
1. A cable modem for connecting Customer Premises Equipment (CPE) devices comprising a Media Access Control (MAC) layer controller; a Logical Link Control (LLC) bridge interacting with the MAC layer controller; an Internet Protocol (IP) stack processing IP frames and interacting with the LLC bridge; CPE interfaces, each CPE interface communicating with one associated CPE device; and a multiplexer of CPE interfaces linked to the CPE interfaces and to the LLC bridge wherein the multiplexer has a table comprising data related to the CPE interfaces, the data being used by an identification function to determine an interface, to which a data frame with a specific receiver physical address is directed, and a table with MAC addresses of CPE devices and identifiers of the CPE interfaces wherein each interface identifier is determined by a check-and-associate function, and wherein records to the table with MAC addresses are added using an adding function, which analyses commands sent by the CPE interfaces to the multiplexers; wherein the multiplexer enables transfer of data between the LLC bridge and the CPE interfaces and wherein each of the CPE interfaces is an application and controls flow of data between the multiplexer and the associated CPE device.
