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.

• Clarifications and additions to requirements for recording originating numbers in originating and terminating AMA records when one or more Signaling System No. 7 (SS7) parameters are received identifying the call's originating number
• 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.
