RE: RFI Pointers to technical organisation layouts

I'm looking for the layout of the technical organisation
within service providers. Charts with role definitions, related and/or
critical processes, inter-departement communications, chain
of command, breakout within major units, relation between
NOC/engineering/billing/service turnup/etc, basically
anything I can get my hands on.
