[EAS] RWT trigger detection

I don't think I made my question very clear.  I know the Sage can take a
remote closure. We're doing that now, but manually.  My question is the
viability to have the box itself decode a two-tone or DTMF string (as an
exmaple) and react accordingly so we can 1)Traffic/automate the RWT
completely and include remote locations in a unified hands-off fully
automated RWT.  This way we can traffic RWT's when our TOC is not manned
over night and one some weekends/holidays. And 2) Run a unified RMT relay
at a time of our choosing for the area.

I know I can do this with external DTMF boxes closing the logic input(s).
But it begs the question about whether it can be done internally with
nothing more than an audio jumper to say input #6 and some firmware code
saving us $xxx per DTMF decoder. Much the same as they do with weather on
input #3 detecting the 1050 tone and the others detecting the old EBS
tones.
