might get a better answer in the nec forum, but you need to meet the SWITCHMAN that you will be working with, at least one of them.. his attitude and knowledge means way more then anything a contract or salesman might imply...
repair stock on hand, response time to an out of service, lead time for changes, if your looking for maint, live monitor of alarms, and a maint schedule, if you can't get a maint schedule, then you do not have maint, period..
those are the things i try to insure as a vendor, but as a switchman, i keep one customer very happy
