32 Each cable is identified by a letter code which defines the type of cable required, e.g.
Cable code H is a 14-core cable. Table 1 provides specifications for each cable type.
Table 2 provides 14-core cable, colour code abbreviations.
33 The cables used to connect Kelvin Hughes equipment are to be to the following
specification. Failure to use the correct specification cables may result in impaired
equipment performance.
