This document presents switching system generic requirements for public telecommunications services. This GR updates a group of
Feature Specific Documents (FSDs) previously found in Issue 2 of TR-TSY-000528, LSSGR: Coin and Charge-a-Call. TR-TSY-000528

This GR is intended to be in the form of a single FSD covering all pertinent aspects of switch requirements relating to public
telecommunications services. The public telecommunications services generic requirements presented in this document supersede any
similar proposed generic requirements published or implied before the publication of this document.
