P1225 DTMF board HLN9432B
What capabilities does this board add to the P1225? I can't really find anything in RSS. Does it allow DTMF decoding for SelCall or Call Alert?

Hello:
The HLN9432B bd was normally used in the P1225 portable to add telephone capabilities so you could make or receive phone calls.
There were other products that would use the bd to encode dtmf command codes for turning on or off an item at other locations but it wasn't what id say real common to be used for this.
Normally phone calls from a tower to portable or portable to another phone through a tower.
Repeaters at towers can be interconnected with the public phone or even a simplex base station.
