Patent ID: 7835274

Claim:
A method, comprising: receiving, at a Cable Modem Termination System (CMTS), a request to assign an Internet Protocol (IP) address for a requesting device; inserting an IP address for the CMTS into the request and relaying the request with the inserted IP address to a provisioning server; receiving back a response from the provisioning server, wherein the response includes an assigned IP address of an address range associated with the inserted IP address of the CMTS, wherein the response includes a download address corresponding to the provisioning server for the requesting device to obtain a first Data Over Cable Service Interface Specification (DOCSIS) configuration file by download from the provisioning server; storing the assigned IP address in a configuration table entry of the CMTS and relaying the response to the requesting device; after relaying the response, receiving from the requesting device the first DOCSIS configuration file; and after relaying the response, receiving from the requesting device a second different DOCSIS configuration file; wherein the requesting device registers twice with the CMTS with each of the registrations sending a different one of said DOCSIS configuration files to the CMTS, wherein the requesting device includes narrowband circuitry and wideband circuitry, and wherein the narrowband circuitry registers with the CMTS according to the first DOCSIS configuration file and the wideband circuitry registers with the CMTS according to the second DOCSIS configuration file.
