MULTI-SERVICE NETWORK INTERFACE APPARATUS FOR FREQUENCY-DIVISION MULTIPLEXED COMMUNICATIONS SYSTEMS

摘要

An interface device and method for selectively coupling the signals of a plurality of communications service providers operating in different frequency bands onto one or more station wire segments of a customer premises wiring plant. The device includes a plurality of service access modules, each of the service access modules comprising a filter network including at least one of a high-pass or band-pass filter, and a low-pass filter connected to a respective communications service provider's signal. A high-band switching module and a low-band switching module are connected to each service access module. At least one station access module is connected to the high-band switching module and the low-band switching module. The station access module includes a filter network comprising at least one of a high-pass or band-pass filter, and a low-pass filter corresponding in pass-bands to the service access module filter network. Each station access module is connected to a station wire segment of the customer premises inside wiring plant. The interface enables each station wire segment of the premises wiring to be concurrently and independently connected to low-band and high-band service providers.
