SLC1024 Overview
This section introduces the SLC1024 and its factory default settings.
5.1 Introduction
The SLC1024 G.SHDSL (G.991.2 Single-pair High-speed Digital Subscriber Line) Line Card is perfect for ISPs
seeking to provide broadband services to subscribers while minimizing costs.
The SLC1024 provides G.SHDSL service for 24 subscribers over existing telephone wiring, thus avoiding the
cost and hassle of installing new wiring.
G.SHDSL allows you to extend the reach of broadband services up to 18,000 feet. This makes the SLC1024
perfect for providing high bandwidth broadband service to subscribers who are spread out over a large area.
G.SHDSL’s symmetric high-speed transfer rates make it a very useful option for businesses.

Port-based VLAN (Virtual Local Area Network)
IEEE 802.1Q Tagged VLAN
Your SLC1024 uses the IEEE 802.1Q Tagged VLAN (Virtual Local Area Network), which allows your device to
deliver tagged/untagged frames to and from its ports. The SLC1024 supports up to 255 VLANs and the maximum
VLAN ID 4094.
IEEE 802.1p Priority
Your SLC1024 uses IEEE 802.1p Priority to assign priority levels to individual ports.
Fast Mode
The fast mode makes use of the “tag” subset of the IEEE 802.1Q standard to identify the source port of a frame
and speed traffic through a service gateway.
