Title: Cable modem and terminal device
Inventor: NARUSE HIROTAKA
IPC: H04L12/46
Filed: 2008-07-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a cable MODEM capable of automatically registering an MAC address for identifying a terminal device to be relayed with a management apparatus, wherein the MAC address of a desired terminal device is preferentially registered without using high-order bit data of the MAC address.  <P>SOLUTION: A ROM 52 of a cable MODEM 30 stores therein a secondary IP address of a terminal device of which the MAC address can be registered preferentially. When registering the MAC address of the terminal device to permit relay of data communication after activation, a CPU 50 first calls the terminal device using the secondary IP address stored in the ROM 52 and registers in a RAM 54 a MAC address of the responding terminal device. Consequently, by registering the secondary IP address of a set-top box in the ROM 52, the MAC address of the set-top box can be registered preferentially.  <P>COPYRIGHT: (C)2010,JPO&INPIT
