System Introduction
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 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 and voice
services to subscribers.
The IES-5000 platform allows for convenient management and support of various
technologies. The IES-5000M chassis can hold a maximum of eight line cards, so up to 384
subscribers (576 when using the ALC1272 72-port line card) can simultaneously utilize a wide
range of powerful broadband services. Additionally, the 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.
1.2 Applications
These are the main applications for the IES-5000:
• Internet access, voice over IP and multimedia services for Multiple Tenant Units (MTU).
• Other applications include video services, telemedicine, surveillance systems, remote
servers systems, cellular base stations and high-quality videoconferencing.
1.2.1 MTU Application
The following diagram depicts a typical application of the IES-5000 in a large residential
building, or multiple tenant unit (MTU), that leverages existing phone line wiring to provide
voice service and Internet access to all tenants (with DSL modems). The MDF is the point of
termination for the outside telephone company lines coming into a building and the telephone
wiring in the building. Note that ADSL/VDSL service can coexist with voice service on the
same line.
