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. The line cords in accordance with the invention comprise a central processing unit (132), an interface unit, (134), at least one modem section (136), a baseband section (140), a signal combining section (138), a signal splitting section (139) and an intermediate frequency section (142).
