Seems simple enough request but for every reference I'm going to give
you someone will point out that some RBOC or other has different requirements,
and they will be quite correct. In fact AT & T actually calls its documents
NEDS not NEBS.
The NEBS conference is going on this week and a new issue of GR-63 is
coming out, but Verizon has already said they would reject it. This is typical
of the process so be prepared to deal with it.
The is a document SR-3580 Network Equipment-Building System (NEBS)
Criteria Levels A Module of NEBSFR, FR-2063. That theoretically defines these
requirements - but Verizon objects to them and places their own requirements on
the different classifications for class 1 through 3. The other RBOCS have some
heartburn with it as well, but it may at least be a starting point.
Very basically there are really only two practical types for switch and
routing equipment. Level 1 for co-locations inside RBOC facilities where the
RBOCs are required to provide space and power to competitors. and level 3 for
Central office locations - (the RBOCs themselves own the equipment).
Next you have to worry about earthquake ratings etc, zones 1 through 4.
No really much sense, in my opinion, of doing anything less than level 4. The
RBOC's have pretty large areas of operation and they all have zone 4 areas. So
unless you are planning on restricting where you equipment goes you'll need to
go to level 4.
You're going to have to sit down with the standards and a good test
house to get this all straight Jim, and then you'll only be close. You have to
deal with NEBS (Purchase the FR-2063 CD referenced about and it contains GR-63,
GR-1089 the SR-3580 document and GR-78 - grab a beer a do some light reading,
and then discuss deviations with a good test house. There are slight
differences for SBC, AT &T, and Verizon just wonders around on their own.
Verizon has it requirements on its website, as does AT&T 802-010-100
but you'll have to dig around on their web site as I don't have the URL's at
the moment.

I'm starting up the learning curve on NEBS compliance, and am looking for
any web resources or articles that would have a management-level primer on
the requirements.
All I know is that it covers EMC, safety, and environmental, there are
different levels (1, 2, and 3?), and different potential customers disagree
on what level we need to have. We need to understand the basic differences
between these levels, how much testing is involved for each level, and what
the cost might be.
Of course we are going to get our hands on the standard(s) and study them,
but in the meantime a primer would be very useful. We would also consider
seminars if there's something close by the Pacific northwest.
Thanks,
Jim Eichner, P.Eng.
