Abstract

A method and system are provided for communicating a wireless signal between an integrated wireless Digital Subscriber Line Multiplexer (WDSLAM) and a wireless hub via a wireless link. The wireless signal includes status information concerning queue utilization levels within the WDSLAM. Upon receiving the wireless signal, the wireless hub determines the queue utilization levels of the WDSLAM and selectively allocates bandwidth among WDSLAMs ensuring efficient utilization of bandwidth.
