LRE/VDSL (Long-Reach Ethernet/Very-high-data-rate DSL)

Introduction

Cisco Long Range Ethernet (LRE) solution leverages Very High Data Rate Digital Subscriber Line (VDSL) technology to dramatically extend Ethernet services over existing Category 1/2/3 twisted pair wiring at speeds from 5 to 15 Mbps (full duplex) and distances up to 5,000 feet. 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) technologies, allowing service providers to provision LRE to buildings where broadband services already exist.
