Communication Server 1000S Overview

Page 12 of 44 Description and features

Introduction

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, refer to Data Networking for Voice over IP (553-3001-160).

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.

WARNING

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.

Telephony Feature Processing is based on the existing Meridian 1 Call Processing software and provides industry-leading feature capabilities.

The Virtual Connection Manager allows IP-based devices that are registered with the Call Server to access the same feature capabilities as existing telephony devices. In this way, the Meridian 1 feature set is made available to evolving IP devices and soft clients, and is the switching foundation of CS 1000S. In addition to access to the Telephony Feature Processing of a Call Server, devices can also access other services in the network, such as XML and IM. The Virtual Connection Manager supports IP Phones and a wider suite of devices and services.

Communication Server 1000S Overview

Page 14 of 44 Description and features

The Circuit Switching Manager evolved from Meridian 1 software. This migration strategy enables Telephony Feature Processing for future releases of CS 1000S to control existing Meridian 1 hardware components. In this way, the investment in existing equipment is preserved while new capabilities are added at a managed pace.

Features

Key features of the CS 1000S system are as follows:

• capacity

• flexibility and redundancy

• software applications

• enhanced system management

• terminal equipment

• interworking/interoperability

Capacity

The CS 1000S Call Server can support up to four Media Gateway 1000S (MG 1000S) systems, and each MG 1000S can support a Media Gateway 1000S Expander (MG 1000S Expander).

The MG 1000S has a Small System Controller (SSC) card and has four available slots for flexible configurations of line and trunk cards.

The Call Server can support up to 1000 IP Phones.

Flexibility and redundancy

The CS 1000S can be deployed in many flexible configurations in a LAN or WAN environment. The system can be deployed in a single location, multiple buildings in a campus setting, or a network of multiple locations with distributed Call Servers or branch offices.
