<P>The LightStream 1010 is the first in a series of switches that will span from 5 to 40 Gbps, providing services optimized for both cell- and packet-based applications. The LightStream 1010 is an excellent complement to the Cisco BPX<SUP></SUP>, AXIS, and IGX WAN switches as well as the Cisco MC3810 multiservice access concentrator, for an integrated ATM WAN backbone. The LightStream 1010, Catalyst<SUP></SUP> multilayer LAN switches, and Cisco routers are the foundation for many large campus ATM networks based on LAN Emulation and Multiprotocol over ATM (MPOA) today. </P> <P> The LightStream 1010 switch processor and port modules can be used in the Catalyst 5500 multilayer LAN switch, providing many options for deployment in addition to investment protection. In metropolitan-area networks, the LightStream 1010 and Cisco 7200 routers integrate video applications, such as distance learning, and voice applications, such as private branch exchange (PBX) interconnect, over ATM circuit emulation. Building upon the Cisco IOS software, as well as supporting the latest ATM Forum specifications and Tag Switching, the LightStream 1010 offers the most complete feature set of any switch in its class. It delivers the performance, scalability, and robustness required for true production ATM deployment. </P>
