linking via the c-Bridge and other 3rd party efforts that
expand the abilities of TRBO networking more generally which
will also drive growth on the independent network operator

redundant talkgroup servers which now provide smooth
day-to-day communications for most of Ham TRBO worldwide.
Simply being able to load the

Other reasons are to explore DMR and TRBO as well as
learning more about the technology, but
also, connections can be simply for special functions such
as hamfests, conventions and other demonstration events.
The connections can be short or long term, scheduled or
impromptu. The beauty of the c-Bridge is that
connections can easily be severed, made dormant until
needed and then reconnected, manually or dynamically. Any administrator or manager of an ISPC network knows how that can be problematic
when adding or trying to delete repeaters from an IPSC
network. But also, this method requires no trips to the hilltops and no worry
about the network security being compromised by a
disgruntled repeater owner or system operator. This
helps to insure that our approach remains politically
neutral across all the independent Ham DMR groups.
Political neutrality has become astonishingly difficult in
the past few years.
General Caution: Do not buy any equipment,
especially DMR repeaters, before
you know it will do what you want to accomplish. Read this

or ask around first. Motorola repeaters are the
standard in Ham DMR c-Bridge networking and no other manufacturers are
able to network to Motorola's MotoTRBO repeaters (directly)
though gateway projects are appearing.
c-Bridge connections to
many other c-Bridges. DCI actively supports the
c-Bridge and the philosophy of
connecting IPSC networks for many reasons and more
especially now, since the creation of talkgroup servers. Most
importantly, peer slots on a simple IPSC network were finite and
operationally, more problematic as the number of repeaters
grow on a single IPSC network.
The c-Bridge broke that limitation wide open and now offers so
much more than a simple party line on 2 time slots.
Talkgroups can be used for routing and this enables the use
more than a single talkgroup on a Timeslot. While not

If you have a c-Bridge, then it can
easily link to our c-Bridges for talkgroups not available
via the talkgroup servers and these types of
links (conference connections) are preferred over that of
putting a c-Bridge peer on your network or your repeater on
our networks. If interested in exploring these options, please Email us at:
