DC Control

DC Control

Catalyst’s Network Access Radio™ (NAR) connects to a DC adapter or DC- ready radio and utilizes changes in DC line current to remotely control PTT. While these radios were typically connected to dispatch consoles or desk-sets with a phone line or leased telephone circuit, Catalyst was the first company to connect DC controlled radios to consoles over an IP based network. The flexible nature of IP networks led to consoles and DC controlled radios to be flexibly distributed over networks, a sharp contrast to the fixed locations required by hard- line telephone circuits.

Network Access Radio™ provides PTT control of most any radio (trunking and conventional) and there are hundreds of NAR Gateways that remain field deployed today.
