I'm a presently-unemployed telecom worker.  My specialty is the Lucent
Technologies (sometimes referred to as AT&T) 5ESS Digital Switch used
for telecom switching and the Tellabs 5500 Titan Digital Cross-connect
System used for telecom transport.  In order to more accurately and
aggressively search for, and ultimately, obtain a job working on
either or both of these pieces of equipment, I need to know which
telecommunications/broadband companies employ and use this equipment
in their networks around the entire world.  It doesn't matter what
type of companies they are or what services they provide, whether it
be local exchange, long-distance, broadband, internet, etc., it should
be all-inclusive.  Included in this list should be contact info for
each company (i.e. address, toll-free telephone number, H.R. email
address, website, etc.).

I used to work for Lucent in the installation group. Also the 5E was my area.

Telecom companies in the MW that have the 5E.  US Cellular has 4 5E's
in the chicago area with about 18 SM's.  4 switches in the VA area
with about 9 SM's.
