Additional subscriber service provision method for telecommunications peripherals

摘要

The additional subscriber service updating method has the communications peripherals (TA1-TAn) coupled to an exchange device (LE) arranged in a group (SHG) to which individual services and/or characteristics are assigned. A specific group call number (PDN) may be assigned to the subscriber group, the exchange device storing the connection information for the subscriber group peripherals and the subscriber service and characteristics information as an organisation unit (OGRP).
