Abstract: A wideband communication system is achieved with apparatus coupled to a wire pair, such as the wire pair provided by a communication services provider at a customer's premises. Disclosed is an embodiment which illustratively employs CDMA as the modulation schema for communicated signals and which, by this means, achieves a bandwidth in the range of 1 MHz. Specifically, a modem is interposed between the wire pair and the customer premises devices which modulates applied signals using code division modulation. The customer premises devices interface with the modem through interfaces that are specialized for the type of device that does the communication, and through a controller that manages the interactions. Illustratively, the apparatus includes the ability to provide one or more POTS ports, an ISDN port, and an asynchronous digital port. Protocol with the provider's network is effected through a signaling channel that occupies a preselected frequency band.
