/ Architecture§
Solution architecture is different for SmartPTT Enterprise and SmartPTT PLUS.
Architecture of SmartPTT PLUS is simple as follows:
- SmartPTT interfaces with main repeater for two-way voice and radio commands (named VRC on the diagram).
- SmartPTT interfaces with DDMS service for presence and sign in/out information updates.
- SmartPTT interfaces with MNIS service for GPS, indoo, TMS, job tickets, and telemetry data exchange.
- SmartPTT interfaces with every repeater individually for air traffic data, repeater “health” information, and individual remote control.
Architecture of SmartPTT Enterprise is complicated:
- SmartPTT interfaces with main repeater for one-way (receive only) voice and radio commands (named VRC RX on the diagram).
- SmartPTT interfaces with MOTOTRBO radios for one-way (transmit only) voice and radio commands (named VRC TX on the diagram).
- SmartPTT interfaces with DDMS service for presence and sign in/out information updates.
- SmartPTT interfaces with MNIS service for GPS, indoo, TMS, job tickets, and telemetry data exchange.
- SmartPTT interfaces with every repeater individually for air traffic data, repeater “health” information, and individual remote control.
Solution components are observed below.
Main repeater§
LCP repeater that performs the following actions:
- Registers other LCP repeaters in the system.
- Routes voice calls between sites if necessary.
- Registers SmartPTT server and dispatchers for at least voice calls delivery for them.
- In SmartPTT PLUS only, accepts voice and radio commands from SmartPTT for their delivery to radio subscribers.
TX radios§
TX radios are MOTOTRBO radios required only in SmartPTT Enterprise. They are responsible for the voice and radio commands transmit from SmartPTT to LCP subscribers.
TX radios must be deployed on RF sites. To interface with SmartPTT, RG-2000 must be used.
In SmartPTT is used for voice recording only in LCP, no need to deploy TX radios.
MNIS§
Software gateway from Motorola Solutions, that provides SmartPTT with two-way interface for data exchange. This includes GPS, indoor, TMS, job tickets, and telemetry.
DDMS§
Software gateway from Motorola Solutions, that provides SmartPTT with two-way interface for presence updates (ARS), and one-way interface for Sign In/Out events registration.
Other Repeaters§
Regular LCP repeaters that provide SmartPTT with air traffic information, health information, and remote control capabilities.
SmartPTT Server§
SmartPTT Server that connects to other components and provide two-way voice, data, and monitoring interface for dispatchers.
