The FCC has mandated all 700 mhz. trs contain TDMA (Phase 2) operating capability. It is the licensee's decision of which baseline or selected combinations of both baselines to use.

Are you forgetting that the FCC has withdrawn their order that the 700 MHz. systems no longer have to go narrow band. Basically this means there is no reason to have to be forced into going phase 2. What this also means is that agencies no longer have to dump all the radio equipment they currently have that won't go phase 2 and have to buy all new user equipment.
Bottom line here is there is no longer a mandate from the FCC to be forced into going phase 2 down the road. Those agencies that don't have user equipment able to do phase 2 can continue to use their existing user radios.
Unless there is a major compelling reason for needing additional RF channels, phase 2 is not even being considered by many agencies now. About time the FCC has done the industry a favor.
