Abstract

A universal broadband server connected between a plurality of subscriber lines, at least one upstream link, and a central office provides broadband service to a plurality of customer premise equipment devices connected to the plurality of subscriber lines. The universal broadband server may also provides analog modem service to the plurality of customer premise equipment devices connected to the plurality of subscriber lines. A dynamic bandwidth allocation method adjusts the transmit power and bandwidth at which the universal broadband server communicates with the plurality of customer premise equipment devices in consideration of the maximum available bandwidth provided by the at least one upstream link, and the maximum available power.

Dependent claims

A universal broadband server, the universal broadband server connected between a plurality of subscriber lines, at least one upstream link, and a central office, each of the plurality of subscriber lines adapted to be connected to a customer premise equipment device, the universal broadband server comprising:

a downstream modem pool;
a physical layer router in communication with said downstream modem pool;
a downstream line interface in communication with said physical layer router, said downstream line interface comprising a plurality of subscriber ports connected to the plurality of subscriber lines;
an upstream modem pool;
an upstream isolation interface in communication with said upstream modem pool, said upstream isolation interface comprising at least one upstream port connected to the at least one upstream links;
a processor in communication with said upstream modem pool, said downstream modem pool, and said physical layer router;
a memory in communication with said processor;
power circuitry in communication with a power source and with said processor;
a central office interface in communication with said downstream line interface, said central office interface comprising a plurality of central office ports in communication with the central office.
