To prove the point delivered below, see the Bell Atlantic Check List (now at Rev. 9) that specifically states this: 1.1.1.1. NOTE: Bell Atlantic does not use or endorse the various conformance levels as described in Bellcore (BCR) Special Report (SR) 3580.
1.1.1.2. All suppliers are advised that Bell Atlantic recognizes only Level 3. 1.1.1.3. No supplier shall assume or expect conformance based on SR3580 Level 1 or Level 2.

This question comes up again and again. Not necessarily in this forum, but from Sales Engineers all over the world. Please, Please keep in mind that these levels ARE NOT endorsed by any North American Telcos that I know of (please prove me wrong). Each Telco seems to have their own set of levels which are conveniently labeled one to three. There is no correlation that I know of. SR3580, Level 2, Zone 2 earthquake is not an acceptable level to the west coast. Please keep this in mind and if anyone knows of a North American Telco, whose operations managers will sign up to these levels as defined by SR3580, please let me know.
