Abstract

An access director provides a gateway for customer premise based equipment (both wired and wireless) and a wireless port facility to a narrowband/broadband information distribution network. It provides a portable narrowband duplex synchronous and isochronous telephony service and concurrent broad fixed location dodwn link from network to customer isochronous service. The down link broadband service may be combined with narrowband up link service to provide non-symmetric duplex operation or services such as interactive video.
