Chapter 5 Configuring BAMS for BAF Output
Generating BAF Records
Note Before configuring BAMS to generate billing and measurements, you should familiarize yourself with
Chapters 3 to 9 of this guide.
Note BAMS performs only limited data validation on the information provisioned into its tables. It is
important that you enter data carefully and understand the algorithms and their implementation.
BAMS values entered through the MML command-line interface are case sensitive; the verbs and
keywords are not.
Generating BAF Records
The following section explains how BAF records are generated from Cisco MGC switch data.
Interworking of BAMS Configuration Tables
The first step in using BAMS is understanding the billing area that must be covered. Are there special
cases for billing within the area? Are there banded areas with special rating? Do some number prefixes
receive different treatment? Are special billing records required for these (or other) circumstances?
The answers to these questions are important in creating zones that are used to define interactions
between different origination and termination NPA-NXX combinations. These interactions also
determine the call types that are used to decide which BAF record to use for billing output. See the “Call
Area Provisioning Example” section on page 5-9 for more details.
Once the billing area information has been gathered, it can be tabulated as shown in Table 5-1.
Prerequisites for BAF Records
The following steps are required before Bellcore AMA Format (BAF) and Cisco Media Gateway
Controller (MGC) End of Call 1110 ASCII records can be generated:
1. The Billing and Measurements Server (BAMS) collects the individual call data blocks (CDBs)
generated by the Cisco MGC. This is performed by the Polling (POL) task.
