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:

Explanation:
The PS ring group has four (for KX-TDA50) or six (for KX-TDA100/KX-TDA200/KX-TDA600) 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 (for KX-TDA50) or six (for
KX-TDA100/KX-TDA200/KX-TDA600) PS members which are in range of two different CSs. When a call
arrives, each CS uses both (for KX-TDA50) or all three (for KX-TDA100/KX-TDA200/KX-TDA600) of its
channels to ring each of the member PSs within its range.
