Protocol Parameter Mechanics
The set of protocol parameters is specified according to a simple
procedure. Individual signal meanings are set to the appropriate MF
tone code. R2 MF tone codes for both forward and backward
channels are defined according to the enumeration in Table 20. If a
signal is not defined for a particular variant, its value is set to zero.
