[Asterisk-biz] D-Channels Dropping During Storms?

[Matt]

I'd be interested in reading the Nortel NTP document (we have a
smaller switch however that was installed by the phone company!!)..

I believe all circuits do come from the same FMT.  Site is fed by
fibre.  The telco equipment is SUPPOSED to be on UPS.. the stuff on
our end is... how about their end?  I dunno..  Not sure about a
potential differential across it.. will have to check.. any ideas on
how to do that?  Cabinets are grounded fairly well yes... how do I
ground an asterisk box though :)  It's a desktop machine sitting on
the desk next to me.
