ABSTRACT: Technology - Webster's New Collegiate Dictionary defines it as a "technical method of achieving a practical purpose." A concise, clear
definition. But for many, achieving that practical purpose can be more than just a challenge. It can be frustrating, intimidating,
time-consuming, and bound to generate the question, "Where Do I Start?"
With the Notes on...series, Telcordia Technologies has devised a starting point for your search through the rapidly developing world
of telecommunications. Written by the authors of the successful Telcordia Notes on the Networks document SR-2275, this series
similarly contains technical material of interest to engineering and planning groups, as well as descriptions of the characteristics
and background of these subjects in layman's terms. The difference is that Telcordia Notes on...zeroes in on one technology in each
document and breaks it down into manageable terms. From the history, background, and basic elements through a discussion of what the
future may bring, our subject matter experts cover the important aspects in as few words as possible.
This release in the Notes on...series, Telcordia Notes on Billing, discusses Call Detail Recording and Usage Measurements in local
exchange networks. A chief characteristic of telephony billing in the United States today is that local service providers, long
distance carriers, and wireless carriers all provide some level of call detail information for the calls made by their customers on
their monthly bills.
This Telcordia Special Report (SR) describes, in general terms, how the usage measurements that capture call detail information are
generated in circuit switches and other measurement points throughout the Local Exchange portion of the Public Switched Telephone
Network (PSTN) in the United States.
With Telcordia Notes on Billing, you will learn about:
- Automatic Message Accounting (AMA), which is the process used by switching systems, packet-switching systems, and other network
elements to provide billing usage measurements data;
- AMA recording and formatting technologies;
- The process of generating service-specific AMA recordings;
- AMA transport to a billing system;
- Future trends in recording in the Next Generation Network (NGN).
