Slightly on the same topic - I have been told different things by different administrators and wanted to know what the "most correct" answer is.
Some systems report via tools like Unitrunker that they are TDMA capable (band plan shows channel IDs with 2 slots), however the talkgroups are all FDMA (and it's known that pretty much all users operate Phase I equipment only, such as XTS5000). I was told by the administrator it would not be marked as "Phase II" until a TDMA talkgroup popped up. Yet some systems, such as Fairfax County, VA show "Phase II" with all FDMA talkgroups.
Should we be reporting systems broadcasting TDMA capabilities as phase II?
