Pretty much sums up the situation. I would add that if the RBOC's don't have
a source and so they need your stuff, they will take it after much
grumbling, but they will take it. The risk is more are you so unique that
they can't get it elsewhere. It's actually a question worth asking because
the testing can be pretty expensive. I haven't exactly tried it but I also
believe that you may be able to start with level 1 while you are making your
way up the test food change. Again, depending on how badly they want it.
As much as the RBOC arrogance annoys me, one in particular, they really do
have a point. When every thing else breaks you can almost always pick up
your phone and hit a dial tone. In the case of natural disasters etc. that
is a pretty handy feature, and they guard it jealously.
You can order a CD of the requirements from Bellcore called Network
Equipment - Building system NEBS - FR-20063.
This is the URL for the Telecordia store. Should be able to find the
standards and their costs there.

The NEBS requirements are not mandatory government standards.
However,
when dealing with RBOCs (Regional Bell Operating Companies) like
Bell Atlantic, Pacific Bell, Ameritech, etc . . . it is recommended that you
meet the NEBS
requirements. If you don't, and your equipment is intended for
co-location in the COs (Central Offices) you risk not making the sale.
Your statement that "equipment is suitable for the customers needs
and to
reduce the time and expenses for the manufacturers", is not the
reason for meeting the standards. The reason is to minimize/reduce the risk
of your equipment causing harm to network critical equipment, and for that
matter any equipment that is in the CO.
The NEBS standards include EMC and PRoduct Safety (GR-1089) and
environmental-seismic, transporation/handling, temp/humidity extremes,
airborne contaminants (mixed gasses and hygroscopic dust), fire spread,
acoustic, illumination/glare, and construction. The three levels range from
Level 1 (minimum requirements) to Level 3 intended for equipment in 'outdoor
plant'. Compliance to NEBS level 3 ensures that the RBOC can locate your
equipment ANYWHERE within their network, whether inside or outside plant.
UL, Telcordia (fromerly Bellcore), and MET laboratories all offer
testing services to NEBS.

I've been through the NEBS testing program. It takes time. Stick
with it.

Hello Ladies and Gentlemen,
I'm looking for information about NEBS compliance. I know there are
3
criteria levels for NEBS compliance devised by Bellcore, to ensure
that
telecommunication equipment is suitable for the customers needs and
to
reduce the time and expenses for the manufacturers. Are they
voluntary or
regulatory testing requirements for telecommunication field in North
America
and/or EU?
Please, any appropriate link would be useful for me. Thank you in
advance
for your help,
Best regards,
Carmen Filimon,
