A conversion module including physical layer and control modules. The physical layer module, via an optical network, receives first data from a service provider. The control module, via a coaxial cable network: transmits the first data, via sub-carriers, from the conversion module to a first network module according to a first bit loading profile; requests from the first or second network module a report that indicates channel conditions respectively for the sub-carriers; based on the request, receives the report; updates a second bit loading profile based on the report; transmits, to the first or second network module, the updated second bit loading profile or a difference between the first and updated second bit loading profiles; and subsequent to performing a switch over between the first and second bit loading profiles, transmit second data according to the updated second bit loading profile to the first or second network module. |

1. A conversion circuit comprising:
a physical layer circuit configured to, via an optical network, receive first data from a terminal of a service provider; and a control circuit configured to, via a coaxial cable network,
transmit the first data, via a plurality of sub-carriers, from the conversion circuit to a first network circuit according to a first bit loading profile, wherein the first bit loading profile specifies a first number of bits to transmit per sub-carrier,request a report from the first network circuit or a second network circuit, wherein the report indicates channel conditions respectively for the plurality of sub-carriers,based on the request, receive the report from the first network circuit or the second network circuit,update a second bit loading profile based on the report, wherein the second bit loading profile specifies a second number of bits to transmit per sub-carrier,transmit, to the first network circuit or the second network circuit, the second bit loading profile or a difference between the first bit loading profile and the second bit loading profile, wherein the difference corresponds to a difference between the first number of bits to transmit per sub-carrier and the second number of bits to transmit per sub-carrier, andsubsequent to performing a switch over between the first bit loading profile and the second bit loading profile, transmit second data according to the second bit loading profile to the first network circuit or the second network circuit. |
