1. A jack for use in a communication system comprising:

  • at least two pair of plug interface contacts, each pair of plug interface contacts associated with a differential signal of the communication system;

    at least two pair of conductive transmission paths connected to the at least two pair of plug interface contacts, the at least two pair of conductive transmission paths passing through a compensation zone and a crosstalk zone; and

    a lattice network in at least one of the crosstalk zone and the compensation zone, the lattice network having a first circuit connected from a first conductor of a first pair of conductive transmission paths of the at least two pair of conductive transmission paths to a first conductor of a second pair of conductive transmission paths of the at least two pair of conductive transmission paths and a second circuit connected from the first conductor of the first pair of conductive transmission paths of the at least two pair of conductive transmission paths to a second conductor of the second pair of conductive transmission paths of the at least two pair of conductive transmission paths, wherein a ratio of a magnitude of the first circuit and a magnitude of the second circuit varies with frequency.
