REDCOM Radio Interface

REDCOM Radio Interface

Connecting VoIP & Legacy Networks with Military & Commercial Radios

REDCOM’s Radio Interface provides a simple and reliable connection between VoIP network systems and two-way radio systems. Radio users gain all the same benefits of a REDCOM system normally available to station users. The feature allows any smartphone, softphone, or analog phone in the network to contact a remote radio, or allows a radio to interface directly into the system and make an outside call or connect with another remote radio system.

Radio Interface Benefits

  • Interconnect with VoIP networks
  • Easy message-based setup
  • Allows back-to-back radio patches with VOX, COR & PTT
  • Security check for encrypted military radios
  • Suppresses repeater squelch tail noise burst
  • Three monitor speaker outputs
  • DTMF dialing for radio direct dialing

Supports VOX, COR & PTT calling

The Interface contains two circuits and supports full two-way calling with Push To Talk (PTT), Voice Operated Transmission (VOX) or Carrier Operated Relay (COR). Each circuit can interface with an HF (pulse) or UHF/VHF (DTMF) radio for simplex or duplex operation. The Interface allows direct, back-to-back radio patches with both VOX and COR.

Effectively suppresses repeater squelch

REDCOM technology removes the annoyance of repeater squelch tail noise found in analog radios commonly in use with police, fire, municipal and commercial/industrial communication networks.

Security check for encrypted radios

Interoperable with encrypted military radios, REDCOM’s Radio Interface verifies that the radio is secure before the voice transmission is enabled.

Adjustable gain

REDCOM’s Radio Interface provides adjustable gain to accommodate radio audio and long cable lengths, enabling geographic distribution between the radio base unit and the REDCOM switch.

Multi-user dial-in monitoring

Several users can monitor radio traffic by dialing in via analog telephone systems, digital (ISDN) phones, or IP phones. This feature can also be password controlled for enhanced security.

Additional Features:

  • Transmission in each direction is VOX controlled, with built-in timing to facilitate transmit/receive transitions.
  • Operating parameters can be changed in the field to accommodate specific radio system characteristics.
  • Parameters are stored in non-volatile RAM for protection if the board is removed or interrupted.
  • Transmits a ring sound over the radio to the remote user to notify of an incoming call (call will not be billed until it is answered).
  • On-board microprocessor controls the 2-way VOX, call progress monitoring, and timing operations without the use of specially equipped phones.
  • Auto answer is available on a port-by-port basis and can answer on ring number 1–255.
  • PTT activation from REDCOM LCS or ISDN CommandSet™ phones.
