Radio Gateway / Telephone Interface

IP_SIP_gateway

The CLASSONE® radio base station controller provides an intelligent, reliable, hardened radio agnostic interface gateway for connectivity to all major UHF/VHF and digital radio base stations. The communication with the radio gateways and network interface equipment can either be 2-W Analog, 4W E/M, or IP/SIP over the VOIP network. When your IP/VOIP network is ready, the CLASSONE® IP/SIP base station controllers can be used to replace your legacy units.

The CLASSONE® TDM/4W E&M Radio Gateway (BSC/RTI) supports radios over analog and 4W circuits. This gateway combines the functions of a Base Station Controller and a Radio Telephony Interface into one unit. It supports migrations from old radio systems to CLASSONE® using the dual-circuit interface. The CLASSONE® Radio Gateway is remotely accessible and programmable. It is interconnected to the distant remote control console by any voice-grade transmission medium such as a microwave link, a leased telephone line, 4W E&M, or a POTS line. The Radio Gateway is capable of decoding  full DTMF for control of the unit. Each control line is capable of functioning in 4W E&M or SF signaling mode. A legacy 2175 decoder is also available to determine PTT. The Radio Gateway acts as a Foreign Exchange Station module with digit translation, audio conditioning, DTMF generation, and processing.

The CLASSONE® Radio Gateway provides the following features:

  • PTT & Monitor Relay
  • PTT, Monitor, COR, and Power LED indications
  • Channel selection and Frequency change
  • Tone Control
  • Hardware and software gain control
  • Local headset port for monitoring activity through the unit and transmission back to base or to radio
  • Front panel Bantam Jacks and level set ports
  • RS-232C port on front panel for configuration via Windows and CLASSONE® administration application
  • DTMF dial-through and dial regeneration modes
  • All timers can be defined via setup software
  • Transient protection has been provided near all audio inputs and outputs
  • Internal Modem interface to support remote configuration and firmware upgrades.
