I have heard TL9000 referred to as TS9000. There is a list group at **** BROKEN LINK REMOVED *** I haven't had much success with this discussion group. There are two related to TS9000
However, TL 9000 is also know as QuEST (Quality Excellence for Suppliers of Telecommunications. The Leadership forum has put together the TL 9000 Handbook. It is a committee draft 1.7 dated 7/28/98. The forum phone number is 925-823-0200. I hope this helps.
