1.20.2 PS Ring Group
Description
A PS ring group is a way for several portable stations (PSs) to be notified of an incoming call simultaneously,
while using only one channel of a cell station (CS).
Normally when a PS receives a call, one channel of a CS is used to ring the PS (→ 1.20.1 Portable Station
(PS) Connection). If several PSs are members of an incoming call distribution (ICD) group, the available
channels of a CS will become busy just by ringing each PS. Assigning a group of PSs to a PS ring group
alleviates this strain on the CS because only one channel is needed to ring a PS ring group's members.
