This part of IEC 60512 defines a test method which is intended to assess the near-end alien
crosstalk (ANEXT) and the far-end alien crosstalk (AFEXT) between connectors in close
proximity, when mounted in their mounting systems. Both discrete modular connectors and
multi-port panel connectors may be tested using this method. This method provides a means to
test the alien (exogenous) crosstalk between any two ports, as well as a means to assess the
overall alien crosstalk from all other ports. This test procedure is generally applicable to any
electrical connector, and is particularly suitable to connectors described in IEC 60603-7 series,
IEC 61076-3-104, and other types of connectors for data transmission.
