I'm splitting this conversation from the other thread so it doesn't turn into a giant hijack.

My head hurts. I have some circuit drawing software on either this computer or my Linux box, so I'll have to start roughing out some pseudo-circuits (rather like pseudocode) for discussion and reference.

I originally posted this:
I'm in the very early (thinking it through) stages of designing a multi-trunking box based on the various slicer designs that are out there.
The box would have:
1 or more computer ports
2 or more radio ports
a 2-level slicer
a 4-level slicer
low-pass filtering, switchable to the 2-level slicer circuit
other useful features I haven't thought of yet
rfmobile replied with these suggestions:
1. econo-version: leave the 2-level circuit out - since the 4 level will provide this for you.
2. some software can't handle multiple inputs (CTS, DCD, and DSR) simultaneously so provide a switch to disconnect two of those pins (this would become your 2/4 level switch).
3. leave the 2-level circuit in - but only provide low-pass filtered audio to it.
4. your 2 vs. 4 way switch becomes ...
a. four level
b. two-level non-LTR (unfiltered)
c. two-level LTR (filtered)
d. two-level LTR and non-LTR (simultaneous on different pins)
5. use external power - allows the RTS and DTR pins to provide software control in place of a manual switch.
Options 5 and 4d above would allow software to automatically switch from one protocol to the next.
