ZyXEL Communications VLC1324G User Manual

VLC1324G User’s Guide

This chapter introduces the VDSL2 line card's general features, default settings and hardware. 

The VLC VDSL2 Line Card is perfect for ISPs or large building applications seeking to 
provide high bandwidth broadband services to subscribers while minimizing costs. One VLC 
provides VDSL2 service for 24 subscribers over existing telephone wiring, thus avoiding the 
cost and hassle of installing new wiring.
The line from the user carries both the VDSL2 and the voice signals.  For each line, the splitter 
card separates the high frequency VDSL2 signal from the voice band signal and feeds the 
VDSL2 signal to the line card, while the voice band signal is diverted to the central office 
switch or PBX (Private Branch Exchange).
Use the Telco-50 connector pin assignments in 

 along with the 

directions and safety warnings in the IES User’s Guide to install the line card and make the 
necessary connections. 

Here are the VDSL2 maximum transmission rates that the VLC supports at the time of writing. 
The actual transfer rates will vary depending on what the subscriber’s device supports, the line 
conditions and the connection distance.
