Distributed Communication System (DCS)
Provides the ability to connect two or more switching systems together to operate as one
large switching system. Each individual switching system is referred to as a node. The DCS
environment consists of all the different nodes connected together.
Feature transparency is provided for a limited number of attendant, voice terminal, and
Applications Processor (AP) features. Feature transparency means that the use of the feature
is the same whether it is being activated within a node (system) or between nodes (systems).
The following attendant features are transparent in a DCS environment:
