How about instead of T for tone, D for digital and the 3 digit DPL code
i.e. D023
And just 1750 for the burst tone repeaters. No Prefix at all.
T000 or T088, T100 etc.
D023, 025,026,031 etc.
1750

Now THAT is really is forward-looking thinking. Cool.....
Now to throw a monkey wrench into the works:
How do we accomodate DCS (Digital Coded Squelch) a.k.a DPL ("Digital PL
- Motorola) a.ka. DCG (Digital Channel Guard - GE) a.k.a DCTS (Digital
Coded Tone Squelch - Icom) into this scheme???
More and more of the newer radios can now encode/decode the 100+ DCS
codes that actually superimposes a continuous stream of digital data,
at
about 131baud, on the transmitted signal instead of a simple sine wave
single CTCSS tone. Sooner or later, we are going to see repeaters
going to DCS. Though most likely mostly closed systems with a small
group of hard core "techie" members.
