19.3 DMO Gateway Timers
A DMO Gateway is equipment that can fulfill two rolls:
1. It acts as a repeater allowing calls between terminals from both the same and different sys-
tems.
2. It also enables system access to terminals in DMO.
A gateway may be installed at a site outside of a cell coverage area to provide extended coverage
for that cell in a particular direction.
