Programming digital handheld radios

[freqwaves]

I have just started a new job were I am involved in programming up new digital & analogue 2 way radios. Programming analogue radios seems to be straight forward with the programs used similar to what we use to program our scanners. But Digital is new to me in that they use "Colour codes" & time slots, especially when accessing a repeater. At present we do not do trunking systems. Models we deal in are Motorola, Kenwood, Hytera & Kirisun.
I look like being one of the tech support experts due to my interest in radio.
Can anyone recommend any good websites or publications to read up on digital technologies in two way radios?

Thanks, John.
