Abstract

A modified ranging request in a broadband communications system. The modified ranging request includes a header, a management message header attached to the header, a management message payload attached to the management message header, and a CRC attached to the management message payload. The management message header enables bandwidth requests to be made by subscriber equipment without contention. The management message header also includes state of health information on the status of a downstream transmission for enabling a central location to determine how to assign subscribers to queues in an adaptive modulation scheme.
