IES-2500 User’s Guide

Chapter 1

Hardware

This chapter describes the key features and applications of your IES-2500.

The IES-2500 (Integrated Ethernet Switch) is an IP-based DSLAM (Internet Protocol Digital Subscriber Line
Access Multiplexer) that connects DSL subscribers to the Internet. As a high-performance yet compact and
versatile platform, it lets multi-tenant units (MTUs), hospitals, hotels, schools, university campuses and ISPs
conveniently deliver broadband Internet access. The IES-2500’s low cost and easy management make it a perfect
DSL-provider solution.

The IES-2500 platform allows for convenient management and support of various DSL technologies. It has the
ability to hold a maximum of six VDSL line cards (without a management switch card) providing service for up to
144 subscribers or five ADSL line cards (with a management switch card) providing service for up to 120
subscribers. Additionally, the DSL line cards are hot swappable; thus, you do not need to interrupt the service of
other cards to change or service an individual card.

Overview

1.1 Front Panel

The following figure shows the front panels of the IES-2500 main chassis and IES-2000 splitter chassis with
installed line and splitter cards.

Card Installation 1-1

1.2 Back Panel

The following figure shows the back panel of the IES-2500 main chassis.

Figure 1-2 IES 2500 Back Panel

1.3 Features

Main Chassis

The main chassis has slots for hot-swappable DSL line cards and a management switch card.

Splitter Chassis

The splitter chassis has slots for hot-swappable splitter and extension cards, and Telco-50 connectors or wire
wrapping pins for connecting to the subscribers and the PBX (Private Branch Exchange) or PSTN/ISDN (Public
Switched Telephone Network)(Integrated Services Digital Network) switch.

Hot Swappable DSL Line Cards

The IES-2500 uses hot swappable DSL line cards.

Hot Swappable Splitter Cards

The IES-2500 uses hot swappable splitter cards.

Management Switch Card

The IES-2500 accommodates a management switch card that switches traffic and forwards it between the DSL line
cards and other Ethernet switches.

Hot Swappable Fan Module

The IES-2500 is equipped with a hot swappable fan module to provide easy maintenance, greater reliability and
increased system operating lifetimes.

Power Module

You can easily access the IES-2500’s power module, located on the upper left side of the rear panel, to change a
fuse.

Scalable Platform for Future Expansion

1-2 Card Installation

IES-2500 User’s Guide

The flexible design of the IES-2500 allows service providers to start with minimum cost. As the number of users
and applications increases, additional DSL line cards can be added to support more subscribers.

1.4 Applications

The following sections describe example applications for the IES-2500. This figure gives an example overview.

Figure 1-3 Application Overview Example

1.4.1 IP DSLAM

The IES-2500 operates as an IP DSLAM in a telephone company’s central office. It provides DSL service over
telephone wires to subscribers. The following figure shows the IES-2500 set up in a telephone company’s central
office.

Figure 1-4 IP DSLAM Application Example

1.4.2 MTU Application

The following figure depicts a typical application of the IES-2500 in a large residential building, or multiple tenant
unit (MTU), that leverages the existing phone line wiring to provide Internet access to subscribers in the building.

A subscriber connects a computer to the phone line in a unit using an ADSL modem. The other end of the phone
line is connected to a port on the IES-2500. The IES-2500 aggregates the traffic from subscribers and then forwards
it through an Ethernet connection to the Internet.
