 GE> Note 1
 GE> There is a potential conflict between packet type 2+ and programmes
 GE> not recognizing that packet type regarding the product code.

 GE> Since the product code in packet type 2 is only an 8-bit unsigned
 GE> integer while it is in packet type 2+ is a 16-bit unsigned integer,
 GE> programmes not recognizing incoming incoming packets of packet type 2+
 GE> may not recognize the complete 16-bit product code.

 GE> Normally this is a minor problem since programmes not recognizing
 GE> incoming packets of packet type 2+ will usually only use this
 GE> information for logging and similar purposes, if at all.

Except that there are programs that compensate for buggy packet formats
produced by some mailers by reading the packet code. 

 GE> To further ease this problem, it is the current practice of the FTSC
 GE> to assign only product codes with FFH as the low order byte (i.e.
 GE> product codes 01FFH, 02FFH, 03FFH, ... FFFFH). A programme only
 GE> recognizing incoming packets of packet type 2 will then interpret the
 GE> product code as FFH which is a reserved 8-bit product code for
 GE> programmes with 16-bit product codes.
