ICD Groups vs. PS Ring Groups
Assigning PSs to either an ICD group or a PS ring group will allow multiple PSs to receive group calls
simultaneously. The differences between the two are highlighted below:
Members can ring simultaneously when a call is received
Calls can be distributed to member extensions using different
methods
The CS is less likely to be busy; ringing all member PSs uses only
one CS channel
Members can log-in, log-out, and use Wrap-up time, ICD Group
button
Both PTs and PSs can belong to the same group
Each member can belong to more than one group
Calls can wait in a queue if they cannot be answered

Explanation:
The PS ring group has four members which are in range of two different CSs. When a call arrives, each CS
uses one channel to ring all member PSs within its range.
The ICD group has one proprietary telephone (PT) member, as well as four PS members which are in range
of two different CSs. When a call arrives, each CS uses both of its channels to ring each of the member PSs
within its range.
