Introduction
The CS 1000S is an IP PBX that was introduced to address the increasing
demand for Voice over IP (VoIP) and support the convergence of voice and
data networks. In addition to supporting powerful new IP features, including
Session Initiation Protocol (SIP), the CS 1000S provides continued support
of the traditional Meridian suite of features.
CS 1000S expands the system’s capabilities to leverage the flexibility of IP
WANs. It provides seamless network integration, simplified management,
greater flexibility in network deployment, and reduced costs for supporting
an increasingly distributed global user community.
CS 1000S is more than an IP PBX. It is the architecture that evolves, using
open standards, to deliver future Advanced Applications, Interactive
Multimedia Services, Integrated Desktops, and Management Services.
Migrating to an IP telephony network
CS 1000S architecture provides an IP-based alternative to traditional
Meridian 1 architecture. It is designed to enable IP-based communication
models while protecting the investment of Meridian 1 end users as they
migrate to new technologies. Figure 1 illustrates the key components of this
architecture.
WARNING
Before a CS 1000S system can be installed, a network
assessment must be performed and the network must be
VoIP-ready.
If the minimum VoIP network requirements are not met,
the system will not operate properly.
For information on the minimum VoIP network
requirements and converging a data network with VoIP,
