Dynamic Talk Groups and Reflector management using DMR Terminal (TRX)

Apart from static Talk Groups(TG), dynamic TG will be created upon transmitting on this TG for first time, TG will be created on same timeslot(TS) it has been initiated. Dynamic TG will state active for either 10 minutes after last transmission has been made or received on this particular TG or it can be deleted / removed by transmitting on TG4000 on respective timeslot. As of December the server will now respond "Not Linked" on either Time Slot, previously only on Time Slot 2.

So to sum this up -

                              TG4000: =  all dynamic Talk Groups disconnection

On HotSpots (DV-MEGA, OpenSPOT,MMDVM) where there is a single TimeSlot (TS2), the same applies - TG4000 disconnects all
