CHAPTER

Overview

This chapter describes the Cisco LRE CPE, a Long-Reach Ethernet (LRE)
customer premis es equipm ent (CPE) device and has the se topics:

• Features

• Front-panel descript ion

• Rear-panel des cript ion

78-11469-04

A Cisco LRE CPE device, hereafter referred to as the CPE, is based on
very-high-data-rate digital subscriber line (VDSL) technology. The CPE connects
a computer or laptop to a Catalys t LRE sw itch at dist ances of up t o 4921 feet
(1500 meters) by using LRE techn ology over ordinar y telephon e lines.

Note A CPE connects a computer or LAN to an LRE switch that transmits a high-sp eed

signal over a telephone d ata c on necti on. A Ci sco LRE CPE converts a
VDSL-based signal on the telephone line to an Ethernet signal to the computer.

The Cisco 575 LRE CPE, Cisco 576 LRE 997 CPE, and the Cisco 585 LRE CPE
have these features:

• IEEE 802.3 10BASE-T com pli ance

• On the 575 L RE CPE a nd 57 6 LRE 99 7 CPE, o ne aut onegoti at ing

10/100BASE-T Ethernet p ort

Features

Chapter 1 Overview

• On the 585 L RE CPE , four au to negoti ating 10 /1 00BASE-T Et he rnet p or ts

• Status LEDs showing Ethernet activity and LRE l ink status

• Data rates of u p to 15 M bp s a t di sta nces of u p to 49 21 feet (15 00 me ters )

Note Data rates are r educed for lo nger distan ces . Data r ates ar e conf ig ured

through a Catalyst LRE switch. Refer to the switch hardware
installation guide and the switch software configuration guide for
your switch model for more informa tion.

• An internal splitter that allows regular telephone services, such as voice or

Integrated Services Digital Network (ISDN), to travel on the same lines as
LRE traffic.

Certain Cisco LRE CPE devices are not supported by cert ain Catalyst 2950 LRE
switches. In Table 1-1, Yes means that the CPE is supported by the switch; No
means that the CPE is not supported by the switch.
