Abstract:
A method of enabling a subscriber's telephone twisted pair to appear at a central office of a telephone network in the absence of a dedicated direct connection between a subscriber station set and the central office, comprising the steps of: creating a virtual twisted pair between the subscriber and the central office, comprising the stepd of:creating a virtual twisted pair between the subscriber station and the central office by: intelligently cross connecting each subscriber signal from the telephone twisted pair to a modem/filter bank; combining subscriber signals by summing the modem/filter bank output; converting the summed modem/filter bank output to a wave division multiplexed (WDM) optical signal; and coupling the WDM signal optically to the central office and reconverting the WDM optical signal to the original subscriber signal by filtering techniques.
