RBX +Plus (Radio Branch Exchange) is an advanced telephone interconnect specifically designed to allow radio users to make and receive phone calls directly on their MOTOTRBO™ radios. The application goes beyond basic telephone interconnects by allowing radio users to access familiar phone-like features, such as call history, phonebook, and caller ID. RBX +Plus streamlines communication between phone and radio users with private calls, talk groups and call groups. The app was designed to easily scale, and it can connect digital two-way radios to something as simple as a standard POTS phone line or as complex as a corporate phone system (PBXs).

System Architecture

RBX +Plus is a software application installed on a server which connects two-way radios to the world of telephony. The server interfaces to the radio system using MOTOTRBO™ control stations (mobile radios). It was designed to connect to IP and analog corporate phone systems (PBXs), public telephone lines (PSTN lines), Internet Telephony Service Providers as well as GSM cellular networks. RBX +Plus interfaces with radios using MOTOTRBO™ control stations which are connected to the server using a custom USB/Audio cable. The number of MOTOTRBO™ control stations is defined by the required number of concurrent radio to phone calls at any given time. The RBX system is compatible with all MOTOTRBO™ digital display radios* in Direct, Repeater, Capacity Plus, IP Site Connect & Linked Capacity Plus modes.
