ABSTRACT: GR-1083 presents the latest changes to Automatic Message Accounting (AMA) data generation requirements in network switching systems.
These systems provide the switched services segment of exchange access service. Switched access services provide, by way of the Local
Exchange Carrier (LEC), access to the local exchange portion of the Public Switched Network. This document contains:
- Exchange access requirements to respond to increasing competition within the telecommunications industry, focusing on
- AMA for network interconnection and wholesale billing
- Addressing call jurisdiction considerations
- Carrier billing
- Bill validation applications.
- Enhancements to network interconnection and exchange access recording capabilities that impact LEC revenue such as local
interconnection usage that goes unbilled, often because measurements are not in place to capture information related to all forms
of interconnection traffic.
Equipment suppliers will avoid the need for retrofitting their interconnection call detail recording (CDR) procedures to meet LEC
customized needs (Telcordia has figured this out and documented it in this GR). Potential cost savings are $150K to $200K.
Service Providers will receive a complete and consistent set of exchange access CDR information from each equipment supplier
(thereby significantly simplifying carrier access billing system [CABS] processing). Potential annual recurring savings is
estimated to be about $100K to $150K per year.
Local Service Providers will find the AMA requirements in this document critical in order to receive revenue from local
Issue 5 contains:

- Updates to requirements for recording Terminating (called party) Numbering Plan Area (NPA) information for when calls are received
with seven-digit terminating numbers.
- Updates for recording information received in the SS7 Originating Line Information Parameter.
