Telecom Glossary B2
Bell Customer Code
A three-digit numeric code, appended to the end of
the Main Billing Telephone Number, that is used by Local
Exchange Carriers to provide unique identification of
customers.
Bell Operating Company - BOC
The local (or regional) telephone company that owns
and operates lines to customer locations and Class 5
Central Office Switches. BOCs have connections to other
COs, Tandem (Class 4 Toll) offices and may connect directly
to IECs like WorldCom, AT&T, MCI, Sprint, etc. BOC
may refer to the nineteen Bell Operating Companies that
are owned by the seven RHCs (Regional Holding Companies)
(not including Cincinnati Bell or Southern New England
Telephone). The BOC role was originally defined by the
1982 Modified Final Judgement that specified the terms
of the AT&T Divestiture). For Example, the three
BOCs: Mountain Bell, Northwestern Bell and Pacific Northwest
Bell are owned by the U.S. West RHC. Each BOC may service
more than one LATA, but BOCs are generally constrained
from providing long distance service between LATAs.
Billing Account Number - BAN
Used by telephone companies to designate a customer
or customer location that will be billed. A single customer
may have multiple billing accounts.
Bill-To-Room
A billing option associated with Operator Assisted
calls that allows the calling party to bill a call to
their hotel room. With this option, the carrier is required
to notify the hotel, upon completion of the call, of
the time and charges.
