This part of ISO\/IEC 11801<\/span> <\/span> establishes a matrix-model for formulating limits for differential mode parameters for return loss, insertion loss, and near and far end crosstalk, within and between two pairs of balanced cabling. This is for the purpose of supporting new, improved balanced cabling channel and link specifications, which are expected to be included in the next edition of ISO\/IEC 11801<\/span> <\/span> 1<\/sup> <\/span>.<\/p>\n
