1. Introductions

The VDS-0120, a VDSL2 (Very high-bit-rate Digital Subscriber Line) PSE LAN Extender,

provides a broadband transmission up to 100/60Mbps of downstream/upstream data rate over

single pair copper line for point-to-point Ethernet connectivity. With 100/60Mbps data rate,

VDS-0120 supports transmission distance up to 300 meters, and 30/10 Mbps for 1km long range

connection. Users may also select a fixed data rate or a fixed SNR margin for different copper line

ranging. With Power Sourcing Equipment, VDS-0120 provides power supply over Ethernet cable to

the 802.3af compliant power device.

With plug and play features and minimum installation time, each VDS-0120 can be configured into

either CO for central side or RT for remote side by dip switch setting. The VDS-0120 conforms to

the ITU-T G.993.1 and G.993.2 to meet VDSL/VDSL2 and SG15Q4 DMT for network requirements.

A pair of V102 and VDS-0120 offers a cost effective solution for bandwidth-hungry applications

such as LAN-to-LAN connectivity, Video Streaming, FTTB, and MDU/MTU over single twisted pair

telephone line.

3. Features

¾ITU-T G.993.1, G.993.2 VDSL/VDSL2 and SG15Q4 DMT Compliance

¾100/60Mbps DownSream/UpStream for distance up to 300 meters

¾Supports VDSL2 connection up to 2000 meters

¾IEEE802.3af compliant -48V Power-Sourcing-Ethernet (PSE) standard

¾Minimum 15.4Watt for Class 3 output power

¾RJ11 for DSL interfaces + RJ45 for Ethernet LAN port

¾Five LED Indicators

¾4 Dip Switches for Configuration Settings

¾Trellis Coding support up to 1024 Discrete Multi-Tone (DMT) bins

¾Auto MDIX for 10/100 BaseT Ethernet LAN Ports

¾Low-Latency for Video/Voice/Data applications

¾Line Surge Protection

¾Selectable Fast and Interleaved modes

zFast mode guarantees a minimum end to end latency less than 1 ms.

zInterleaved mode provides impulse noises protection for any impulse noise with a

duration less than 250 us. Interleaved mode has a maximum end to end latency of 10

ms. Interleaved mode is the default mode.

¾Selectable fixed data rate and fixed SNR margin

zUser may select fixed SNR margin (9 dB) or fixed target data rate.

zWhen fixed SNR margin is selected, the systems will maintain the SNR margin at 9 dB

across all available loop length.

zWhen fixed target data rate is selected, the system will lock the data rate at 50/20Mbps

whenever the calculated SNR margin is higher than 9 dB. This will result in the best

system stability and is the default mode.

4. Packing Contents

Inside the package you should find:

(1) One VDS-0120 VDSL2 PSE LAN Extender

(2) One AC to DC Power Adaptor (DC12V/2.5A)

(3) One User Manual CD

Please check if the packing is damaged or any component is missing. If so, please contact your

distributor.

5. LED Indicators

On the front panel of VDS-0120, there are four LED indicators as the following

VDS-0120 Rear Panel

POWER:“Green On” indicates power is on and normal.

LAN:“Green On” indicates Ethernet LAN port is in connection.

“Flashing” indicates Ethernet LAN data activities.

DSL:“Green On” indicates VDSL2 is in connection.

“Flashing” indicates VDSL2 is in line handshaking.

M/S:“Green On” indicates VDS-0120 is set as Slave (VTU-R) mode.

“OFF” indicates VDS-0120 is set as Master (VTU-C) mode.

PSE:“Green On” indicates VDS-0120 is providing power over Ethernet.

“OFF” indicates the Power Sourcing Equipment is OFF.

6. Dip Switches Settings

Pin 1 Pin 2 Pin 3 Pin 4

VTU-C/R Mode Rate Limit SNR

OFF VTU-C Interleaved 50/20 Mbps 9dB

ON VTU-R Fast Full Rate 6dB

Pin 1: VTU-C/R Switch

VTU-C: VDS-0120 will act as at the Central Office (CO) side.

VTU-R: VDS-0120 will act as at the Customer Premise Equipment (CPE) or Remote side.

Pin 2: Mode for impulse noise protection

Interleave mode: Protection for up to 250ms impulse noises with latency less than 6 ms.

Fast mode: Direct data transmission with latency less than 1ms.

Pin 3: Rate limit control

50/20 Mbps: Line rate limited to 50/20 Mbps.

Full Rate: Provides up to 100Mbps/60Mbps line rate in short line.

Pin 4: Signal to Noise Ratio (SNR)

9dB: Higher SNR margin (9dB) will result in less error with more stable VDSL2 link.

6dB: Original and Normal channel noise protection with 6 dB SNR.
