I need a list of telecommunication equipment distributors, such as
Graybar and Anixter.

Hello,

Thanks for your question. Yahoo has a category for Telecom Equipment >
Distributors at
[http://dir.yahoo.com/Business_and_Economy/Business_to_Business/Communications_and_Networking/Telecommunications/Equipment/Distributors/]

I found that by searching Google [://www.google.com] for
[telecommunications equipment distributors]. Anixter and Graybar are
not on this list. So I continued my search with Google by looking for
[Anixter Graybar]. I thought I might find a telecommunications
equipment manufacturer’s site that listed their distributors – and
that is what I found. The most extensive list is below:

Viking Electronic Distributors
http://www.vikingelectronics.com/distrib/distributors.html

These lists are by no means exhaustive, but I wasn’t sure if you
wanted an exhaustive list or just a good base list. If this will
suffice as an answer, please let me know and I’ll mark it as answer.
If you are looking for more I wish you luck and I hope this helps!
