1083 Reverse Billing On Circuit Switched Access *

* Note that this name has been changed slightly, and the description has
been modified so that it no longer includes packet, compared to the
information published in the May 24, 1989 BOC ONA Special Report #5 and 
December 29, 1989 BSA Matrix Supplement documents.  For information on the 
packet version of this service, see the service called "Reverse Charge

Reverse Billing provides the ESP's client with the ability to make calls
to the ESP without the ESP's client being billed for charges associated with 
the calls (e.g., message units, measured service charges, intraLATA toll), 
which might otherwise apply.

FEATURE OPERATION:
The reverse billing feature provides the end user the ability to access the
local Enhanced Service Provider (ESP) telephone number without incurring
local message units or intraLATA toll.  The Reverse Billing service is
applicable to all calls terminating to an ESP's service provided the
NPA/NXX for the ESP exists within the dial plan area.

TECHNOLOGICAL AND FEATURE INTERACTION CONSIDERATIONS:
1. This feature is available in the following central office switches:

Switch Type			1A ESS	5ESS	DMS-100
Earliest Generic Release	1AE8A	5E2(2)	BCS17

2. For a voice grade line circuit switched application, reverse billing is a
   function of the billing systems.  The technology to provide reverse billing
   is dependent on two systems - the central office where the call originates
   must have recording capability, and the billing systems must be able to
   process the billing information and reverse the billing to the terminating
   telephone number.  In order to make the billing systems' tasks less complex,
   a unique NXX must be assigned for the reverse billing telephone numbers.  The
   unique NXX indicates to the billing system that calls placed to numbers in
   this NXX must be treated differently than normal calls.  The switching 
   equipment in each LATA must have the capability to code convert all seven
   or ten digits of the unique NXX to facilitate completion of the call to 
   the ESP.
