 Long-Reach

Solution

The Cisco Long-Reach Ethernet (LRE)

networking solution delivers cost-effective,

high-performance broadband access to

multiunit (MxU) buildings (hotels, residential

multidwelling units [MDUs], and multitenant

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.

Catalyst 2924 LRE XL Switch

The Cisco LRE solution includes Cisco

Catalyst

®

 2900 LRE XL switches, the Cisco

575 LRE and 585 LRE Customer Premise

Equipment (CPE) devices, and the

Cisco LRE 48 POTS Splitter.

The Cisco Long-Reach Ethernet solution

delivers everything needed to quickly deploy

an Ethernet-based network with the

performance required to deliver high-speed

Internet access at much greater distances and

drive services like IP telephony and audio/

video streaming. With this technology, a broad

range of customers can benefit from lower

operating costs and rapid deployment. The

LRE solution provides multicast, Layer 2

quality of service (QoS), security,

and Web-based Cisco Switch Clustering

network management.
