Changing the Hop Code
It is advisable to change the eight digit hop code (for the entire hop network) on a
regular basis.
The frequency of code change with a network is entirely dependent on the situation
that exists at the time.
Code Distribution
Code distribution will be the same as for any other direct entry crypto devices - i.e.
this is a logistics issue for the person/organisation administering the hop network.
Network Planning and Contingencies
As the Barrett 2000 series frequency hopping system has a GPS based
synchronisation system that requires no master station allocation, operating the
system requires the minimum of communications strategies.
The network users have only to be briefed on the channel and security codes to use
the system.
