As I know from our DMRplus-sysops in Germany, they say you need to set in the options-line all 2 TS, TG not used need to be setup by zero. You have 5 TGs for slot1 and 5 TGs for slot2 and the option to setup a startup-reflektor. My option line (from dmrgateway): Options="StartRef=4039;RelinkTime=15;TS1_1=0;TS1_2=0;TS1_3=0;TS1_4=0;TS1_5=0;TS2_1=0;TS2_2=0;TS2_3=0;TS2_4=0;TS2_5=0;"
And I know too - the DMRplus team is not agree to bridge other network systems to the IPSC2-network, they thinking other than BM about such things. I had a lot of discussion about. That's what I know - they gave me clear information about this.
