Overview
This section introduces the ALC1024 and its factory default settings.
4.1 Introduction
The ALC1024 ADSL Line Card is perfect for ISPs seeking to provide broadband services to subscribers while
keeping costs low.
The ALC1024 provides ADSL service for 24 subscribers over existing telephone wiring, thus avoiding the cost
and hassle of installing new wiring.
The ALC1024 also simultaneously combines voice service on the same telephone wiring, thus saving subscribers
the cost and inconvenience of installing an extra phone line.
ADSL allows you to extend the reach of broadband services up to 18,000 feet. This makes the ALC1024 perfect
for providing high bandwidth broadband service to subscribers who are spread out over a large area.
