Data Sheet


Catalyst 6000 Family FXS Analog Interface Module


The analog interface module provides enterprises with the ability to connect legacy analog telephony equipment such as phones, speaker phones, and faxes to Cisco Catalyst® 6000 switches.

The Catalyst FXS Analog Interface Module integrates legacy analog devices into the campus multiservice network within Cisco AVVID (Architecture for Voice, Video, and Integrated Data). (See Figure 1.) By providing legacy analog devices with access to the benefits of the campus multiservice network, the useful life and thus the return on investment (ROI) of these devices can be maximized. Migration to a fully converged multiservice network is also simplified.

Benefits of Converged Networks

Based on an Internet model, converged networks rely on a distributed architecture to ensure system availability and scalability. With the trend continuing toward distributed computing, customers are quickly realizing the benefit of having no single point of failure and are able to build as little or as much availability as they need into an integrated solution.

Another key element of a converged network is its open and interoperable nature. This means that customers can choose the best-in-class solution in a number of different areas, where previously they were locked into proprietary applications from a single vendor. As a result, innovation is encouraged and overall networking costs will come down based on market demands and competition, resulting in a lower total cost of ownership (TCO).

One of the primary benefits of a converged network solution is the ability to deploy advanced applications for a competitive advantage while minimizing information technology (IT) expenses. Converged networks based on the Internet model have a distributed and open architecture. Through this open architecture, developers can write next-generation applications on leading development platforms such as Windows NT, TAPI, and JTAPI, ultimately providing customers with a wide range of innovative options.

Supporting Analog Telephony in a Converged Network

At a minimum the analog phone or fax machine needs to behave as if connected to a normal central office or private branch exchange (PBX), and in this respect the Cisco Catalyst foreign exchange station (FXS) analog interface module emulates the central office or PBX.

The analog interface module provides a gateway function between the analog world and the enterprise IP network, offering access to the full benefits of the converged multiservice network. The gateway function encodes the audio signals to G.711 or G.729a, depending on the application, and applies quality of service (QoS) to ensure audio quality. (See Figure 2.)

Extending Analog Station ROI

The analog interface module provides an FXS interface to analog end stations such as analog phones, conference-room speaker phones, and fax machines. This provides a gateway for these devices into the campus multiservice network. Modems are currently not supported devices.

Since analog phones and fax machines can participate in the multiservice network, they have access to new advanced applications and can communicate with devices such as IP phones and H.323 end stations and gateways. The life cycle of these analog devices is extended and the ROI is increased.

Migration to Campus Multiservice Network

Fax machines and conference-room speaker phones are essential elements of a telephony network and should be part of a campus multiservice network. The FXS analog interface module integrates these devices into the IP network.

The migration to a campus multiservice network is simplified by integrating these analog devices into the IP network. Access to and from these analog devices is maintained and they can be migrated to IP end stations over time. (See Figure 3.)

Extended Management Capabilities

With the integration of legacy analog end stations, network administrators will require new tools and features to manage the interface module and associated devices. The FXS analog interface modules provide the network administrator with extended management features to control and monitor the telephony configuration, sessions, analog ports, and devices. Network management interfaces include Catalyst command-line interface (CLI), CiscoWorks, Cisco Voice Manager, and Cisco CallManager.
