Abstract: A method and apparatus for configuring connectivity at a hub having a plurality of subscriber lines from a plurality of subscriber premises and a plurality of feeder lines from a central office. The hub provides connectivity between the plurality of subscriber premises and the central office. The method and apparatus include categorizing the plurality of subscriber lines into a plurality of groups based on penetration rates and churn rates of the plurality subscriber lines. Each group of subscriber lines are connected to feeder lines based on the penetration and churn rates for POTS and/or DSL services. Subscriber line groups with high penetration rates and high/low churn rates are coupled directly to feeder lines. Subscriber line groups with low penetration rates and high/low churn rates are terminated at the hub. Subscriber lines with an intermediate penetration rate are candidates for being connected to the feeder lines via an automatic switch.

Abstract: Apparatus for providing connectivity at a hub having a plurality of subscriber lines and a plurality of feeder lines. The apparatus includes a first switch module for coupling to N of the plurality of subscriber lines, where N is an integer. The first switch module is also for coupling to a digital subscriber line access modem (DSLAM) at the hub. A second switch module is coupled to the first switch module and the DSLAM. The second switch module is also adapted for coupling to M of the plurality of feeder lines at the hub, where M is an integer.

Abstract: Reduction of administrative overhead in maintaining network information, rapid convergence on an optimal routing path through the data network, and utilization of only required network resources are realized by a novel method for establishing a call path between network users. The method is based upon deployment of a network information server that stores network topology information and that is addressable by each end user. In this method, the network information server receives a request to establish a call path. The request identifies at least the calling party. In response to the request, the network information server determines a network traversal between the calling party and a root network wherein the network traversal includes call path information about the sub-networks between the calling party and the root network. The request for establishing a call path can also identify the called party.

Abstract: Establishing voice calls in an IP based VPN includes determining the relative location of a terminating point with respect to an originating point of a new communication containing the voice data, determining one or more IP addresses to egress the communication from the originating point to the terminating point, creating a VPN identifier in the new communication, passing the new communication to the terminating point and removing the VPN identifier from the new communication. The VPN identifier can be an extra field added to an encapsulation coding scheme of the voice data.

Abstract: A method and apparatus for providing virtual private network (VPN) connectivity between at least two customer sites. Each of a plurality of PE routers includes at least one access module adapted for connectivity to at least one customer site. The access modules are generated automatically for each PE router associated with a VPN, wherein customer sites, which are associated with said VPN and have an identical export route target (RT) value and import RT value, are connected to a common access module. Otherwise, customer sites associated with the PE router that do not have identical export and import RT values are coupled to their own respective access modules at the PE router. Each access module generates an ingress-forwarding table for routing packetized information between the at least two customer sites.

Abstract: An automatic and adaptive time-domain equalizer with a first transversal structure operating on received signal samples has its convergence properties improved by the addition of a second transversal structure operating on detected signal samples and having its tap-gain settings conjugate, i.e., reversed in time, with respect to those of the first transversal structure for effectively measuring the spread of tap gain values generated at the first transversal structure and a third transversal structure also operating on received signal samples but having its tap-gain settings determined by the spreading error. The matrix product of the spreading-error tap-gain values and received signal samples modifies the up-dating of the tap-gain values controlling the first transversal structure. The resultant faster convergence is particularly useful in the presence of severe amplitude distortion in the data transmission channel.
