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

1.1 System Description

The Integrated Ethernet Switch (IES) Multi-Service Access Node (MSAN) connects subscribers to
the Internet and voice services. As a high-performance yet compact platform, it conveniently gives
telephone companies and Internet Service Providers (ISPs) the ability to deliver broadband Internet
access and voice services to subscribers. The IES platform allows for convenient management and
support of various technologies.
The IES can hold a maximum of four line cards, so up to 128 DSL and 256 VoIP subscribers 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.

1.2 Applications

These are the main applications for the IES:
• 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 in a large residential building or
multiple tenant unit (MTU). This application leverages existing phone line wiring to provide voice
service and Internet access (with DSL modems) to all tenants. The MDF (Main Distribution Frame)
is the point of termination for the outside telephone company lines coming into a building and the
telephone wiring in the building. Note that xDSL service can co-exist with voice service on the same
line.
