SLC1224 Overview
This chapter introduces the G.SHDSL line card's general features, factory default settings and
hardware.
1.1 SLC1224 Overview
The SLC1224 G.SHDSL Line Card is perfect for ISPs or large building applications seeking
to provide high bandwidth broadband services to subscribers while minimizing costs. It
connects up to 24 G.SHDSL subscribers.
G.SHDSL is an acronym for Single-pair High-speed Digital Subscriber Line. ITU-T G.991.2
defines the "G." in "G.SHDSL".
The SEC1024 (SHDSL Extension Card) sends the SHDSL traffic to the rear of the splitter
chassis.
Use this chapter's Telco-50 connector pin assignments along with the directions and safety
warnings in the IES-2000's or IES-3000’s User's Guide to install the cards and make the
necessary connections.
