ALC1024 Overview
ALC1024 Overview 1-1
This chapter introduces the ADSL line card’s general features, factory default settings and hardware.
1.1 ALC1024 Overview
The ALC1024 (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.
WARNING
The ADSL line card has no surge protection!
The ADSL splitter card protects against power surges and lightening on the telephone lines.
Use other surge protection on the telephone lines if you do not use the ADSL splitter card!
Please contact your distributor or customer support if you have further questions (see the
customer support page for contact information).
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.
The following features, default settings and hardware specifications apply to the ADSL line card used with the
MSC (Management Switch Card).
