How to read a cable code: guides per coding system

How to read a Swiss cable code

A Swiss designation (Switzerland) is a row of letter groups, and each group stands for one part of the cable: conductor, insulation, screen, armour, sheath, or the standard it follows. The decoder knows 64 symbols for this system. Below: real designations read step by step, then every symbol grouped by the part of the cable it describes.
