They also use a number of ports allowing for simultaneous QSOs.

DMR reflectors:

DMR reflectors consist of several regional servers that are connected
with each other via a superordinate network. Two nets exist. One
based on Hytera and the other based on Motorola technology. As
Hytera is open towards Ham Radio the DV4mini sticks check into the
Hytera based network. In the meantime there are also some cross
connections existing that allow communication beyond ones net
limits.

Net organization (CCS7):

The many reflectors, repeaters and also Dongle users (the DV4mini is
a Dongle too) require a structured organization, so that the network
technology works properly.
D-Star works with call signs to identify a station. DMR however uses
numbers. That is why it is necessary that an amateur radio station
gets a number assigned in addition to its call sign and that this
call sign - number combination is known to the network.
Every ham can go to the web site xreflector.net and request a 7 digit
number to be assigned. This number is then entered into the specifc
feld on the DV4mini software. This facilitates reporting into the
network and conduct worldwide contacts in D-Star or DMR and the
use of D-Star/DMR bridges.

Operating modes:

Digital ham radio repeaters are connected via reflectors. This allows
for worldwide connections from one repeater to another.
With a hotspot (DV4mini) one creates ones own connection to this
reflector network and gets access to all connected ham radio
