This chapter introduces the ADSL line card's general features, factory default settings and hardware.

1.1 Integrated Ethernet Switch Overview

The Integrated Ethernet Switch is an IP-based DSLAM (Internet Protocol Digital Subscriber Line Access
Multiplexer) that connects DSL subscribers to the Internet. It includes the following components:
The IES-3000 or IES-2000 main chassis.
o The ALC1224 ADSL line card (documented in this user's guide) provides ADSL service for
subscribers.
o The management switch card controls the Integrated Ethernet Switch and connects it to an
Ethernet backbone network.
The IES-3000 or IES-2000 splitter chassis.
o The ASC1024 is a splitter card (documented in this user's guide) combines phone service and
ADSL.

1.2 ALC1224 Overview

The ALC1224 (ADSL Line Card) provides ADSL service for 24 subscribers over existing telephone wiring, thus
avoiding the cost and hassle of installing new wiring. ADSL allows you to extend the reach of broadband services
up to 18,000 feet. This makes the ADSL line card perfect for providing high bandwidth broadband service to
subscribers who are spread out over a large area.
The ASC1024 (ADSL Splitter Card) combines voice service and ADSL on the same telephone wiring.
Use this chapter's Telco-50 connector pin assignments along with the directions and safety warnings in the
Integrated Ethernet Switch's User's Guide to install the cards and make the necessary connections. Install the
ADSL line card in the main chassis. Install the ADSL splitter card in the splitter chassis.
