Cisco Systems WS-C2950ST-24-LRE

The Cisco Catalyst 2950 Long-Reach Ethernet (LRE) solution delivers cost-effective, high-performance intelligent services to enterprise campus environments and multi tenant buildings (for example, hotels, apartment buildings, and office buildings). The Catalyst 2950 Series is an affordable product line that brings intelligent services, such as enhanced security, high availability and advanced quality of service (QoS), to the network edge - while maintaining the simplicity of traditional LAN switching. The Cisco LRE technology dramatically extends the reach of Ethernet up to 5000 feet over existing Category 1/2/3 wiring at speeds from 2 to 15 Mbps symmetric. LRE co-exists on the same medium as Plain Old Telephone Service (POTS), digital telephone, and ISDN traffic, and co-exists with asymmetric digital subscriber line (ADSL) in the same wire bundle, allowing service providers to provision LRE to buildings where broadband services already exist.
The Cisco Catalyst 2950 LRE solution includes the fixed-configuration Cisco Catalyst 2950 LRE switches, the Cisco 575 and 585 LRE customer premises equipment (CPE) devices, and the Cisco LRE POTS Splitter. Each LRE link is terminated with either the Cisco 575 or 585 LRE CPEs, and a POTS splitter is required when POTS traffic coexists with the LRE link over the same line. The two built-in Gigabit Ethernet Small Form-Factor Pluggable (SFP) ports support 1000BASE-SX and 1000BASE-LX modules. The dual SFP-based and copper Gigabit Ethernet implementation provides customers with tremendous deployment flexibility - allowing customers increased availability with the redundant uplinks. Embedded in Catalyst 2950 Series switches is the Cisco Cluster Management Suite (CMS) Software, which allows users to simultaneously configure and troubleshoot multiple Catalyst desktop switches using a standard Web browser. In addition to CMS, Cisco Catalyst 2950 LRE switches provide extensive management tools using Simple Network Management Protocol (SNMP) network management platforms such as CiscoWorks for Switched Internetworks.
