5.2 Capacity Plus legacy trunking network
The figure below shows the typical topology used when building the dispatching system on the basis of the
SmartPTT software in the Capacity Plus Legacy trunking network without the use of the MOTOTRBO Network
Application Interface protocol (hereinafter referred to as the NAI protocol). The given mode is called Capacity Plus
Legacy.
Fig. 16 Capacity Plus network in Legacy mode: connection via the pool of the remote control stations
In this connection method, the radioserver is connected to the repeaters directly via an IP network. Repeaters
transmit the voice calls (both Group Call and Private Call) and data received from the radio subscribers to the
radioserver over the IP network.
The radioserver, in turn, transmits the control commands and voice calls from the dispatcher to the radio
subscribers via control stations. This transmission is performed via the pool (in the given example, 4 units) of the
remote control stations connected to several RG-1000e GATEWAYs.
The number of the remote control stations depends on the number of required simultaneous calls from the
dispatcher/dispatchers. In general, the number of the remote control stations must not be greater than the
number of the trunking voice channels (in the given example, 4 voice channels) in the Capacity Plus network.
More detailed information on the configuration of the control stations in Capacity Plus Legacy mode is contained
in the «MOTOTRBO SYSTEM PLANNER» (“System Topologies” chapter) and «Capacity Plus Deployment
