Systems integration started early with Tacticom and our sister company Plymouth Telecom Services. Way-way back in the 70s and 80s when we were using 5tone selcall to remotely control the motor function on emergency shelters in the Norwegian Arctic. Now we can integrate all the known (and the unknown) makes of PMR, DMR and dPMR radio systems to any number of cellular, POC or other land - air or sea communication audio pathways using class leading JPS gateways.
