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.
