jms, your message highlights the extent to which various systems with different 
missions in life come to interact with one another - 0R NOT. To wit, event 
correlation, network performance, line and port configs & inventory, etc. What 
I've not seen here spoken about much (if at all) has been the link between 
billing systems and all of the above. I recently undertook to reconcile billing 
discrepancies for a business unit in a large corporate account (a very large intl 
bank with 132 pops around the globe), and I found that there was no linkage 
between their *multiple,* internal bill-back systems (which naturally factored in 
markups to leased line costs that are paid by IT) and the circuit inventory 
systems. This has to be an issue with BBPs and ISPs, too, I'd imagine, if 
accurate and up to date billing is an interest. The manual processes that I had 
to endure in tallying the live circuit charges, and separating those charges from 
those being assessed for the "dead wood pile" were quite unbelievable in this day 
and age.
