For more update any questions and inquiry please visit: [email protected] http://gctechnologies.in/ GCT-IP Link provides Voice over IP (VoIP) communications between Land Mobile Radios, Telecom systems, SATCOM terminals and VoIP networked communication terminals over internet or other TCP/IP networks. GCT-IP Link is designed to support a variety of configurations, from simple point to point extension of radio network over intermediate links such as LAN, Internet or satellite to complex networks of multi-site connectivity. The system provides next generation radio and intercom communication capabilities while dramatically reducing size, weight and power requirements over previous generation technology. GCT-IP Link integrates 1 Radio / Audio port, a VoIP Gateway, Client-Server, and Call Manager into a single compact, light weight and low power system. It runs on embedded Linux platform and provide seamless interface between radios using open standards Voice over IP technology. Version is available with 2 radio/audio ports. The system has been designed to transport signalling schemes such as DTMF over data networks. GCT-IP Link overcomes the problem of degradation of audio tone due to compression algorithm resulting in poor signal decoding by directly decoding analog signaling tones and encoding them into data messages. Similarly, the reverse operation ( analog encoding ) is performed at the transmission end. It is also equipped with audio pre / post processor for optimum signal conditioning. It is capable of producing exceptional audio quality at a very low bandwidth. The system analog radio/audio port features transformer isolated 4-wire audio, Carrier Operated Switching (COS) inputs and relay operated PTT transmit control. It also provides Voice Activity Detection (VAD) and silence suppression. VAD is useful when connecting to communication equipment that do not provide a COS or Mute output. It performs a VOX function. GCT-IP Link is configurable via in-built web server for system parameter configuration.
