SRAPP consists of five major subsystems: Collection, Processing, Distribution, Storage, and Backup.

See a Screen Shot of the Main Recording Application


Data is retrieved into the system block-by-block and formatted into tape image files.  A real-time background process then processes these files into logical components such as IBM or DMS standard tape labels, binary AMA data files, and batch header and trailer information.    These files are stored and copies are sent to the Processing subsystem.

Tape Image files for down stream data deployment in IBM Labeled Tape format are cataloged, and placed in the Storage subsystem.  These files provide the root data recovery source if re-processing is required


Another real-time background process now processes these files to the dual database host servers.  All file conversion activity is logged and the files are made available to the Storage subsystem.  Functions such as normalizing, filtering, reformatting, mapping, as well as other user-defined operations occur here.  Normalized database tables are now ready for immediate System Query Language (SQL) analysis.  Standard Belcore or Nortel AMA formatted binary flat files are placed in the Storage subsystem and are now ready for immediate teleprocessing and deployment to billing systems.

Header and Trailer tape label information, as well as AMA file Header and Trailer record information is cross-checked with processing counters and all information is stored to the dual database host servers.   If discrepancies are found, the errors are recorded in the log files and a notification message is dispatched to all Remote Monitor Consoles.

Optionally, in real-time, another background processing task performs an integrated conversion process that builds EMI-210 formatted billing records.  These standard EBCDIC encoded files are placed in the Storage subsystem ready for billing.


The Storage subsystem catalogues and places the processed files in shared disk space for a specified period of time.  This shared disk space area is protected by standard and enhanced security mechanisms that allow and restrict access to the data in a security wise environment.   Catalog and Log File information is provided in both Database Table format and Flat Text File format – flat text log files have their own directory.  Database file catalog and log entries can be easily reported with SQL.

Files marked as being downstream processed are quickly and automatically moved to a sub directory for an additional selected period of time.  The files remain here for recovery or re-processing by the system in the event of downstream failures.   Files remain until taken off-line by the Backup subsystem.


The Distribution subsystem supports file distribution to remote sites
Data can be pushed out over the network automatically using FTP or TFTP
Data can be pulled out onto the network using the integrated FTP Server
Other authenticated Windows systems can directly access the data
Unix systems can directly access the data using Network File System (NFS)

AMAStore® Application

AMAStore® is the front-end convergence processing application for SRAPP.   AMAStore® is a complete integrated processing module that converts Automatic Message Accounting switching system records to a standard database format for rating, billing, analysis, and redistribution.

AMAStore® has been designed to provide high-power unattended batch processing of multiple AMA sources. AMA data collected in real-time is automatically processed to the common database without continual user interaction.

  • Detects and protects against duplicate blocks
  • User defined filtering, reformatting, and data validation
  • The ability to easily accommodate user-defined processing tasks
  • Proven compatibility with existing billing systems
  • Extensive error reporting and logging capabilities
  • Builds normalized congruent database tables independent of switching system type
  • Efficient high speed processing
  • No data is ever discarded


User Reporting and Analysis Application  (AMAReport Desktop Suite)

AMAReport comes with the most popular analysis queries built right into the Windows based Graphical User Interface.  These queries provide immediate access and review of switching system test call, routing, timing, and billing data.

Provides switching system tradesmen and management personnel with instantaneous verification of call data

  • Helps improve routing related profitability
  • Helps prevent fraud
  • Helps prevent revenue leakage at the source
  • Helps verify billing system accuracy
  • Helps verify Carrier Access Billing Charges
  • Helps detect and Report Transit Tandem Usage
  • Provides Real-Time AMA record search and report generation
  • Find and Report Wireless and CLEC terminating usage
  • CIC / OCN Usage Reporting
  • Traffic & Engineering / Busy-hour studies
  • Quickly locate and review tracers and call traps
  • Phantom Traffic Detection

Extensive Management Report Generation Tools

SRAPP has been certified for operation utilizing Microsoft Windows 64-Bit Technologies and Server Platforms.   Interface with Unix Operating System is achieved utilizing Windowa Server 2003 R2 64-Bit Network Files System (NFS).

Web interface Optional

Because the SRAPP Host Server Systems are state-of-the-art open-architecture systems, it is possible to add processing module functionality including Data Filtering, Coping, Reformatting, Auditing and User Defined Distribution Processing.

In addition to the standard processing features, Sierra can provide custom processing modules based on user-defined requirements.  Such modules can perform processing functions that automatically upload to centralized computing centers and ensure that important data arrives at selected destinations in a timely fashion.
