Introduction
The IP-distributed architecture of CS 1000S offers the benefits of location
flexibility for system components. The architecture also provides wiring
control and simplification of space planning, system management, and
databases.
CS 1000S bridges the circuit-switched PBX and the IP network, or it can
operate in an IP-only network. This consolidation of network traffic
simplifies the task of managing communication to a single, efficient IP
network. End users can deploy the CS 1000S in many flexible configurations
