A communication network (30) for connecting widely separated computers (136), local area networks (32) and cable television system subscribers includes a wireless local loop (34) for connecting to a packet switched network (36). A router (86) directs data traffic destined for an address outside a LAN (80) to a transceiver (88). The transceiver (88) transfers the data through the airwaves to a second transceiver (100). A coder-decoder (108), coupled to the second transceiver (100), digitizes any analog data from the LAN (80). A second router (112), connected to the coder-decoder (108), directs the data to one of a plurality of digital switch units (114). The digital switch unit (114) provides clocking and a carrier for the data and passes the data to a frame relay access device (116) that forms frames of the appropriate format for the frame relay network (104).
