The LightStream® 1010 is the first member of Cisco Systems' midrange Asynchronous Transfer Mode (ATM) switches for multiservice applicationsfrom the ATM workgroup and campus backbone to metropolitan-area networks and alternative service provider backbones.
Building upon 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 production ATM deployment.
The LightStream 1010 uses a five-slot, modular chassis featuring the option of dual, fault-tolerant, load-sharing power supplies and can support up to eight hot-swappable port adapter modules (PAMs). The 5-Gbps, shared-memory, fully nonblocking switch processor of the LightStream 1010 and the port modules can be used in the Catalyst® 5500 multilayer LAN switch. In either platform, up to eight OC-12 (622-Mbps) ATM ports can be supported.
OC-12-ATM Port Adapter Module
Unlike other switch architectures, the shared-memory architecture of the LightStream 1010 allows all the advanced traffic management and other mechanisms of the switch to be implemented not on the port modules, but on the field-replaceable feature card on the switch processor module. This scenario lowers the costs of the interface modules and facilitates the upgrading of switch features without impacting the port modules. Future members of the LightStream family of switches will utilize all the current PAMs, preserving investments and facilitating the sharing of spares.
The multimode fiber 622-Mbps Synchronous Optical Network (SONET), (STS-12c)/Synchronous Digital Hierarchy (SDH) Synchronous Transport Module level 4 (STM-4) PAM supports a single port. With a typical reach of 500m, the module is ideal for very high-performance intercampus links. This PAM supports an SC-type connector for ease of use.
The SMF, 622-Mbps SONET STS-12c/SDH STM-4 PAM supports a single port, and with its intermediate reach of 15 km, it is ideal for very high-performance intercampus, metropolitan, or wide-area links. This PAM supports an SC-type connector for ease of use.
The SMF, 622-Mbps SONET STS-12c/SDH STM-4 PAM supports a single port, and with its long reach of 40 km, it is ideal for very high-performance intercampus, metropolitan, or wide-area links. Because of its expanded distance, this module is extremely useful in service provider networks. This PAM supports an SC-type connector for ease of use.
