On This Day in Telephone History November 13TH 1888 Patent Issued for Crisscrossing of Overhead Telephone Wire to Prevent Crosstalk Between Parallel Lines. Patent issued on an elementary scheme of wire transpositions which had been worked out by John A. Barrett, who had been assigned to this work for the Bell System, beginning in 1885.
