There is disclosed an access system formed by the coupling of a Wireless Local Loop (WLL) system to a Digital Loop Carrier (DLC) system. This coupling is such that the DLC system supports the WLL system. This coupling is achieved by the provision of a remote unit for the DLC system that includes cards for accommodating voice/data transmissions to/from "wired" subscribers, typically already on the DLC system, as well as cards in accordance with the present invention for accommodating voice/data transmissions to/from "wireless" subscribers, those on the WLL system. In making this coupling with the apparatus and methods of the present invention, the need for a service provider's installation and maintenance of separate DLC and WLL systems is eliminated, WLL system subscribers, by way of being coupled to the DLC system, can now receive the additional services that were only available over the DLC system, and the WLL system can reach more subscribers, as it can not be placed further from the central office (exchange) by virtue ofthe DLC system.
