Introduction
The process of configuring, engineering, and deploying a Communication Manager system, or a
network of Communication Manager systems, begins with specifying the quantity and the
nature of the endpoints to be accommodated. Principles of traffic engineering are then applied
to determine the quantity and the placement of the various necessary resources. Once the
designed configuration adheres to all specifications and system constraints, the process is
finished.
