RED applies to ports, not to spans. Or rather, it applies to certain
types of communication lines and the use of it to analog lines is just a
logical extension.

Zaptel terminology of spans has originated from cards in which each span 
represents a port. In the analog card in which that applied (the X100P)
a disconnected cable generated a red alarm for as long as I remember
(read: since at least zaptel 1.0).

Is /proc the right place? Or /sys ?

Also look at http://bugs.digium.com/12406

(Unfortunetly the submitter has not done a good job at separating
different parts of his patch nd thus you'll have to review ztdynamic
code changes as well)
