The only situation that comes to mind is electrical surges that come in
through the phone line which can hose one modem, all of them or even the
entire PC setup (moral of the story is use proper grounding!). The more
'wires' that come in from other sources - cable internet, dsl connections,
internal networks, the more you have to secure your grounding, and that
_all_ devices are linked to a common ground source. BE VERY ANAL ABOUT
THIS!
In the case of an lightning electical surge, there's no brand that will
offer better tolerance for such events, kasi malas lang talaga...!
Matamaan ka ng kidlat, pasensya na.. AFAIK, there's an APC product that's
supposed to 'protect' equipment from such disasters, but really, how does
one protect oneself from lightning bolt discharges?

most often it's hardware, and the modem does not respond to an 'ATZ'. In
this case, the phone will just keep on ringing, and the mgetty/portslave
software will not be able to detect a ring. The only cure for this case
is to power cycle the computer.

My sentiments exactly. It's worth it just eliminating the clutter, and
yes, there will be less items that could be unplugged if ever the janitor
decides to 'clean' your NOC. <g>
