DEMHS should still be utilizing the VHF Low and High bands. The VHF High band frequencies are utilized by the the 5 regions' town EOC's in CT to communicate with each other and the state. Not every single town will be on the CLMRN or have equipment to it. It is possible that these VHF High Band frequencies could be patched in to the CLMRN system. As for the two VHF Low Band, not sure what their disposition is. I'll do some more research and see if I can find out any more information and get it to you correctly.
