Preface
About this User’s Manual
This user’s guide gives hardware specifications and explains web configurator and command line configuration,
management and troubleshooting for the ADSL line card. It also gives hardware specifications for the ADSL
splitter card.
ALC1224 Models and Firmware Releases
The firmware version contains a model code. In firmware version V3.50(LK.0) for example; “LK” is the model
code.
 “LK” denotes the ALC1224-71 for ADSL over POTS (Annex A).
 “LV” denotes the ALC1224-73 for ADSL over ISDN (Annex B).
A firmware version also includes the firmware’s release number. In firmware version V3.50(LK.0) for example,
“0” is the firmware’s release number. This varies as new firmware is released. Your firmware’s release number
may not match what is displayed in this User’s Guide.
General Syntax Conventions
 Mouse action sequences are denoted using a comma. For example, click Start, Settings, Control Panel,
Network means first you click Start, click or move the mouse pointer over Settings, then click or move
the mouse pointer over Control Panel and finally click (or double-click) Network.
 “Enter” means for you to type one or more characters. “Select” or “Choose” means for you to use one of
the predefined choices.
 Predefined choices are in Bold Arial font.
 Button and field labels, links and screen names in are in Bold Times New Roman font.
 A single keystroke is in Arial font and enclosed in square brackets. [ENTER] means the Enter, or carriage
return key; [ESC] means the Escape key and [SPACE BAR] means the Space Bar.
 For brevity’s sake, we will use “e.g.,” as shorthand for “for instance”, and “i.e.,” for “that is” or “in other
words”.
Naming Conventions
See also the Integrated Ethernet Switch Overview in chapter 1.
 The ALC1224 (ADSL Line Card) may be referred to as the “ALC”, the “line card” or the “card”.
 “ALC1224” refers to the ALC1224-71 for ADSL over POTS (Annex A). “ALC1224” also refers to the
ALC1224-73 for ADSL over ISDN (Annex B). Differentiation is made where needed.
 The ASC1024 (ADSL Splitter Card) may be referred to as the “splitter card”.
 “ASC1024” refers to both the ASC1024-61 for ADSL over POTS (Annex A) and the ASC1024-63 for
ADSL over ISDN (Annex B) versions. Differentiation is made where needed.
 The IES-2000 or IES-3000 may be referred to as the “Integrated Ethernet Switch”, the “switch” or the
“system”.

ALC1224 Overview

Part I:
ALC1224 Overview
This part introduces the general features default settings and hardware of the ADSL line card.

ALC1224 User’s Guide
ALC1224 Overview 1-1
Chapter 1
ALC1224 Overview
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.
1.3 Features of the ALC1224
ADSL Compliance
• Multi-Mode ADSL standard
 G.dmt (ITU-T G.992.1)
 G.lite (ITU-T G.992.2)
 G.hs (ITU-T G.994.1)

 ADSL2: G.992.3, G.992.41
 ADSL2+: G.992.5
• Rate adaptation support
IEEE 802.1p Priority
Your ADSL line card uses IEEE 802.1p Priority to assign priority levels to individual ports.
Multiple PVC and ATM QoS
The ADSL line card allows you to use different channels (also called Permanent Virtual Circuits or PVCs) for
different services or subscribers. Define channels2on each DSL port for different services or levels of service and
assign each channel a priority. ATM Quality of Service (QoS) allows you to regulate the average rate and
fluctuations of data transmission. This helps eliminate congestion to allow the transmission of real time data (such
as audio and video).
IEEE 802.1x Port-based Authentication
The ADSL line card supports the IEEE 802.1x standard for centralized user authentication and accounting
management through an optional network authentication (RADIUS) server.
Protocol
Multiple Protocols over AAL5 (RFC 1483)
Management
• Remote configuration backup/restore and firmware upgrade
• SNMP manageable
