Methods are provided for reducing port to port crosstalk on a multiport assembly. Steps of the method include placing at least one BEMI in at least one compensation region, disposed on a PCB. The BEMI reduces port to port crosstalk noise by generating an opposite polarity signal to an unwanted noise signal generated through port to port adjacency. The PCB includes a plurality of ports, at least including adjacent first and second ports, each of which is an RJ45 jack port. Each port of the plurality of ports includes a plurality of modular insert pins, and is associated with an IDC pin group. The at least one compensation region includes one or more regions for generating noise compensation with respect to crosstalk noise resulting from coupling between respective modular insert pins of, or IDC pins associated with, the first and second ports, respectfully.
