Stackable VDSL Switch With Gigabit Ethernet  Interfaces
Stackable VDSL Switch
Features
DHS-3212V/DHS-3224V
The DHS-3212V /DHS-3224V  Stackable VDSL Switches leverage the extraordinary bandwidth promise of VDSL technology, the next step in 
the delivery of new high-speed Internet applications to home and office users. As CO (central office) devices, these switches provides VDSL 
access to the CPE (consumer premise equipment) such as the Bridge Remote Units from the subscribers in the multi-unit, multi-tenant 
buildings. These switches connect to the service provider's public optical network (PON) through their Gigabit Ethernet fiber interfaces. The 
DHS-3212V/DHS-3224V thus provide the last-mile connection by extending the public high-bandwidth network to people living and working 
in business parks, apartments, dormitories, campus and hospitals. 
High-speed Internet Access
Preserving Existing Infrastructure
Proven Performance at 1,500 Meters
Scalable Expansion
With VDSL, you can now have smooth delivery of streaming 
media, video conferencing, media-rich Web surfing and intensive data 
exchange. VDSL operates over the copper wires in your phone line in 
much the same way that ADSL does, but at as high as 15Mbps 
downstream and 15Mbps upstream. This compares with 8Mbps 
downstream and 800Kbps upstream for the highest ADSL G.dmt full 
rate.
The DHS-3212V/DHS-3224V switches preserve users' existing 
infrastructure by delivering data at multi-megabit asymmetrical 
throughput per port to the subscribers side over any twisted-pair wires.
The switches deliver VDSL speeds at extended cable distance coverage. 
Proven distance is 1,050 meters (3,000 feet) on the ordinary phone line 
or Cat. 3 wiring. Depending on the quality of the cable (Cat. 4 or 5 or 
better), your data throughput can be up to 5Mbps at 1,500 meters, 
10Mbps at 1,200 meters, and 15Mbps at 1,050 meters.
The switches are stackable to 6 units per stack, giving your installation 
the flexibility of scalable expansion. 2 port density selections are 
available:
  DHS-3212V with 12 VDSL ports
  DHS-3224V with 24 VDSL ports
Ethernet Connection
Complete FTTH/FTTB Solution
Both switches provide an open slot for installation of an optional 
Ethernet port module. Port modules available for selection include:
DHS-321GL 1000BASE-LX module supporting 5 km fiber cable 
  distance. This module provides a Gigabit port to connect the switch to a 
  public optical network.
DHS-321FX 100BASE-FX module supporting 2 km fiber cable 
  distance. This module provides a Fast Ethernet fiber port that can be 
  used to cascade together stacks of  VDSL switches located in different 
  buildings.
DHS-321FL 100BASE-FX module supporting 15 km fiber cable 
  distance. This module 
provides a Fast Ethernet fiber port that can be 
  used to cascade together stacks of  VDSL switches located in different 
  buildings.
DHS-321TX 10BASE-T/100BASE-TX module. This  module provides 
  a Fast Ethernet twisted-pair port that can be used to cascade VDSL 
  switches that are closely clutched together. This port can also connect 
  to a management station to configure and monitor the traffic going 
  through DHS-3212V/DHS-3224V stack.
The DHS-3212V/DHS-3224V Stackable VDSL Switches are part of 
D-Link's total solution for Fiber to the Home/Fiber to the Building that 
takes advantage of the VDSL-over-Ethernet technology. This solution
