ABSTRACT:
A wireless telecommunications system includes a central station communicates with a plurality of subscriber stations served by the central station. The central station is connectable to a telecommunications network under a multiplexed multi-channel digital data telecommunications protocol having a plural number of data channels. Each subscriber station provides a line connection for carrying a predetermined number of digital data channels, where the plural number is greater than the predetermined number. The central station is connectable to each subscriber station via a wireless link under a wireless link protocol having the predetermined number of data channels. The central station includes a central protocol interface for converting between the multi-channel telecommunications protocol and the wireless link protocol for each wireless link. The subscriber station includes a subscriber protocol interface for converting between the wireless link protocol and the multiplexed multi-channel digital data telecommunications protocol with the predetermined number of digital data channels active. By converting an incoming multi-channel digital data protocol to a wireless link protocol, and then reconverting the wireless link protocol to a multi-channel digital data protocol at the other end, it is possible to provide for selective communication in accordance with the multi-channel digital data protocol, despite the limited bandwidth available.
