The Cisco Long-Reach Ethernet (LRE) networking solution delivers cost-effective, high-performance broadband access to multi unit (MxU) buildings (hotels, residential multi dwelling units [MDUs], and multi tenant unit [MTU] office buildings) and enterprise campus environments such as manufacturing, educational campuses, and medical facilities. Cisco LRE technology dramatically extends Ethernet over existing Category 1/2/3 wiring at speeds from 5 to 15 Mbps (full duplex) and distances up to 5,000 feet. (Actual achievable data rates depend on cable quality, noise and cross talk environment.) The Cisco LRE technology delivers broadband service on the same lines as Plain Old Telephone Service (POTS), digital telephone, and ISDN traffic. In addition, Cisco LRE supports modes compatible with asymmetric digital subscriber line (ADSL), allowing service providers to provision LRE to buildings where broadband services already exist.
