Introduction

Making Converged Networks a Reality

Introduction

The Cisco ICS 7750 is an all-in-one solution that enables you to migrate from a circuit-switched network to an IP telephony network. The Cisco ICS 7750 is a six-universal-slot, industry-grade chassis system. Each universal slot accepts a router/gateway or single-board computer card to address the widest range of data and voice connectivity and application needs.

By deploying the Cisco ICS 7750 with quality of service (QoS)-enabled Catalyst series switches, you can choose the switching solution that best meets your needs.

The Cisco ICS 7750 also supports the Cisco IP Phone 7900 series, a new generation of display-based intelligent communication devices that can be powered from Catalyst 3524-PWR XL switches, an integrated Catalyst switch card, or the Catalyst inline power patch panel.

Figure 1-1 shows the Cisco ICS 7750 chassis with two Catalyst 3524-PWR XL switches.

Description

Multiservice router/voice gateway

Multiservice Route Processor 200 (MRP200) and MRP300

MRP3-8FXOM1 card

Analog station interface (ASI)

1-6

MRP200 and MRP300 cards run Cisco IOS and provide the functionality of multiservice routers and H.323-compliant voice gateways.

MRP3-8FXOM1 provides MRP capabilities along with analog Foreign Exchange Office (FXO) M1 support.

Analog station interface (ASI) cards add support for high-density analog Foreign Exchange Station (FXS) ports (8- and 16-port versions are available). Flash memory is an option that is available for the MRP and ASI cards.

Single-board computer/
application server

System processing engine (SPE)

1-6

SPE cards run integrated Web-based system management software (Cisco ICS 7700 System Manager), call-processing software (Cisco CallManager), and IP telephony applications (Cisco Unity).

Ethernet switch

System switch processor (SSP)

7

The SSP card runs Cisco IOS and integrates the Cisco ICS 7750 with your switched Ethernet 10/100 backbone.

Hardware monitor

System alarm processor (SAP)

8

The SAP card sends fault detection and system monitoring information to the fault management module that is embedded in the Cisco ICS 7700 System Manager software.



Note For additional information about processor cards, see Chapter 2, "Processor Cards Feature Summary."


Making Converged Networks a Reality

The Cisco ICS 7750 is a new offering in the Cisco Architecture for Integrated Voice, Video, and Data (AVVID) product line. By combining the elements needed to build a complete IP telephony system, including data and voice networking, the Cisco ICS 7750 provides a truly "converged" solution. The modular design of the Cisco ICS 7750 gives you the flexibility to choose the capabilities you need now while enabling you to add capacity, redundancy, and e-business applications as your needs change.

Cisco AVVID

The Cisco ICS 7750 is built on the open and scalable Cisco AVVID. Cisco AVVID includes three components: infrastructure, such as switches and routers; clients, such as IP phones, H.323 videoconferencing equipment, and PCs; and applications, such as call control. Cisco AVVID is an architecture for integrated data, voice, and video over a common IP transport. For more information, refer to the white paper Architecture for Voice, Video and Integrated Data.

Cisco IP Telephony Architecture

Cisco AVVID is an open, standards-based architecture for Voice over IP (VoIP). Unlike traditional office environments, in which the data and voice networks are separate (see Figure 1-2), in a converged network, the telephony and IP components are integrated (see Figure 1-3).

Advantages of Converged Networks

Because converged networks use a single, packet-based infrastructure for all data, voice, and video communications, implementing such networks reduces costs. The following are additional advantages of converged networks:

Budget leverage. You can reduce your telecom budget and devote the money saved to other purposes, such as information systems.

Integration of campus and branch office networking equipment. By deploying products such as the Cisco MCS 7800 series, the Cisco ICS 7750, and Cisco IP Phones, you can phase out proprietary technologies with high capital and operations costs—such as private branch exchanges (PBXs).

Support for emerging software applications. Use of the open, standards-based Cisco AVVID architecture helps you take advantage of the latest business applications, such as unified voice and e-mail messaging, web-based call centers, and computer telephony integration (CTI).

Cisco IP Phones do away with the costs and inconvenience associated with traditional telephone moves, adds, and changes by taking advantage of the Dynamic Host Configuration Protocol (DHCP).
