Q. Why is Cisco delivering the Cisco Catalyst 2955 Series?
A.The migration to Ethernet that began in the enterprise space ten years ago and has moved into the metro, wireless, and service provider markets is now extending to other networks (manufacturing control networks, for example). As Ethernet becomes ubiquitous and far more competitive than any other Layer 2 technology, new markets outside the traditional enterprise wiring closet are converging on Ethernet. New markets require hardware implementations that address the new and different environmental conditions that differ from “traditional” applications.
The Cisco Catalyst 2955 allows Cisco to provide an
The traditional Layer 2 networks that are being replaced with Ethernet solutions have been highly reliable and secure, but significantly limited in terms of bandwidth, interconnectivity, and standardization. By deploying intelligent Ethernet solutions, Cisco can deliver the benefits of an Ethernet architecture with the reliability and security that are a hard requirement in these new markets.
Q. Why is the Cisco Catalyst 2955 the best solution?
A. From a technology perspective, Cisco is the only solution in the market that provides intelligent services in a hardened platform. Most of the networks that are being replaced with Ethernet carry critical information that cannot tolerate latency, downtime, or intrusion from unauthorized users. Multiple features of the Cisco Catalyst architecture, including support for rapid spanning tree, IGMP snooping, storm control, and MAC address notification are critical to establishing a deterministic, secure, and highly available network. These features are only provided by the Cisco Catalyst product family.
From a solution’s perspective, only Cisco can provide an
Q. Are all ITS networks compatible with the Cisco Catalyst 2955 Series?
A. ITS architectures are rapidly moving to a TCP/IP infrastructure. Currently, ITS networks use several architectures, including Synchronous Optical Network (SONET), Asynchronous Transfer Mode (ATM), serial, coax, Ethernet, and wireless. The NTCIP standard has recommended TCP/IP for data structures (for more information, see http://www.NTCIP.org). To be

Q. Why does the Cisco Catalyst 2955 not offer a lifetime warranty like some other Cisco Catalyst products?
A. Given that the environments where the Cisco Catalyst 2955 can be deployed are significantly more demanding and uncontrolled and no active cooling is feasible, the product has a
