Manual conventions

Several conventions are used in this document. While certain acronyms are standard in the telecom industry and are understood by most readers, this document treats network components and feature name as proper names and spells out their names to improve the reading of this document.

For some process descriptions, figures or tables are displayed at the beginning of the process to allow the reader to follow most of the process on the same page. This convention is identified with each process.

Where “end points” are mentioned, the full range is included: Service Switching Points (SSPs), Signaling Control Points (SCPs), Home Locator Registers (HLRs), and Short Message Service Centers (SMSCs).
