Greg,

Type 15 is reserved and should not be used. Type 5 is intended to 
support all TrueTime radios. TrueTime is has been eaten by Symmetricom, 
although a couple of the TrueTime GPS gadgets may continue for awhile 
with Symmretricom numbers. The various TrueTime radios were decidedly 
different.
