RHC: Thanks Jim. Some of those I hadn't thought of. The ones that I
suspect might be the problem are the presence of DSL on the line. I
have found that Paradox are immune to DSL while DSC normally do
require the Excelsior(sp?) alarm filter right off the batt.  I hadn't
thought of a low backup battery or transformer output, but I find it
hard to visualize how that could cause the problem (but I'll start
checking them out anyway).
TLM is always enabled, as well as touchtone only, plus spreading out
the tests as you suggested is a matter of course now.

I'll give those things a whirl and see it if helps...
