Trunk sites questions (split bands and trunk/conv)

I think I've asked this before but it bears some clarification if the DB head admin and/or other DB admins can offer some insight.



A P25 phase 1 system being built in my province will have some 700 MHz multi-channel (traditional) trunk sites, and some 700 MHz single-channel (voice on control) sites, some VHF single-channel (voice on control) sites - and some sites which will have 700 MHz and VHF together, in both 700 traditional trunk coupled with VHF VOC, and 700 VOC coupled with VHF VOC. The documentation insinuates that the sites with two bands in use will have both "sites" transmitting the same WACN, SysID, RFSS, and SiteID on two separate control channels at the same geographic location, one for each band. How would the RRDB reflect that accurately?



There will also be sites in this system which will have VHF conventional P25 repeaters linked to the trunk, with the appropriate talkgroups used on each conventional site (i.e. if Police Dispatch is tg 1500 on the trunk, the P25 conventional channel will broadcast it on tg 1500 as well). Any thoughts on how that would be ideally represented in the DB? Just a conventional channel entry with a link to the trunk system's DB entry included?
