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

[Mike Spike]

You should not be losing your PRIs or DS3s due to bad weather.  First
off do you know if they were down on your end or far end?  Is your
equipment properly grounded with seperate S.P.Gs?   Do you know if
your nortel gear, and other equipment was installed based on the
Nortel NTPs with regards to site engineering?  Do all your circuits
come from the same FMT?  Do you know if your site is fed by fibre with
a telco switch to provide facilities or are they running copper from
another site?  Is the telco equipment on UPS?  Do you know if your
equipment has a potential difference acrost it which might cause
issues?  Are all your cabinets properly grounded as well?

There are various scenarios which could cause your links to go down,
be it electrical hit, conduits filling with water and shorting or
whatever, but proper installation should limit your outages.

I can dig up the nortel install NTP for their larger switches, 81c,
and e-mail it to you directly if you would like to see what the
recomended Nortel install looks like.

Regards

Michael Spike
