CHAPTER 1

System Description

This chapter describes the system features, specifications and applications of the IES-5000

series.

1.1 System Description

The IES-5000 series are IP-based DSLAMs (Internet Protocol Digital Subscriber Line Access

Multiplexer) that connect DSL subscribers to the Internet. As a high-performance but yet

compact and versatile platform, they can conveniently give telephone company central offices

and Internet Service Providers (ISPs) the ability to deliver broadband Internet access to DSL

subscribers.

The IES-5000 platform allows for convenient management and support of various DSL

technologies. The IES-5000M chassis can hold a maximum of eight line cards, so up to 384

DSL subscribers can simultaneously utilize a wide range of powerful broadband services.

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. A single management switch

card can provide the convenience of centralized network traffic supervision.

The IES-5000 also has dual, hot-swappable power modules that reduce the chance of system

shutdown.
