The only way an alarm company can tell if the line was cut is if they're
using alternate frequencies (Similar to how DSL over voice typically
works) -- This would be completely incompatible with DSL.

The only other option is if there is an alternate communications method
available -- If the alarm system detects a phone outage and it switches
to some sort of radio method instead.

[TELECOM Digest Editor's Note: I do think it best that he have a
security person from Brinks there to make the actual cutover, and not
cause them to get all excited if it fails for some reason. PAT]
