After clients purchase large quantity of POC radio, one of the main problem they face is how to realize the communication with existed analog system, DMR system, Tetra system or PDT system.

At the current stage, wireless communication system as an emergency communication system plays an important role in dispatching, commanding and management among the sections or organizations. The brand manufacturers like Motorola, Kenwood, Hytera and etc. create their own system with different protocols to suit applications. Each system developed is independent of others which means they can’t be interconnected with each other directly.

Meanwhile, the POC radio as a new communication technology is becoming more and more popular. One solution to provide powerful connectivity options is a need. That is why Contalketech lauched the PTT radio voice gateway CTET-ZLINK-4.

The radio gateway supports interconnectivity among trunking system PDT, MPT1327, TETRA, DMR Radio , DPMR Radio and Poc radio. Briefly speaking , the gateway is used to link your existing DPMR/PMR/DMR/Analog/Digital radio network to the Poc network.

The gateway adopts advanced technology of voice interaction. The pickup, acquisition, sampling, encoding, compression, and restoration of all voice are fulfilled in a highly integrated voice chip. In such way, it guarantees high quality voice without distortion. In addition, the webpage management is provided for easier controlling. The gateway delay is less than 150ms (mess spectrum), meaning it is fast.

Briefly speaking , the gateway is used to link your existing DPMR/PMR/DMR/Analog/Digital radio network to the Poc network. The 1 to 4 port solution means the voice interoperability among four channels of any system.  The dynamic reorganization of up to four temporary talk groups raises flexibility of operation. Besides the interconnectivity of different systems and protocols, the gateway also supplies solution of wireless digital audio link to solve the voice link issue in an “island” where there is no signal coverage. The image will give you a clear idea of the digital audio link solution.
