GR 588 CORE : ISSUE 1

This document is a module of LSSGR, FR-64. Defines the generic requirements for the Customer Premises Message Registers feature. ABSTRACT Message registers allow the customer to receive a running account of the accumulated message units on lines with this feature. This is done by providing charging information, in terms of message units, based on the duration of each call, the location of the called party, and the type of calling party. This service is mainly used by Private Branch Exchange (PBX) customers such as hotels, motels, hospitals, and other business customers; however, the feature may be applied to any line that does not have four- or eight-party service.
