1 Introduction
VDSL2 LAN Extender is a Long Reach Ethernet media converter with one
Ethernet port (RJ-45 connector) and one VDSL port (RJ-45 connector).
This model is a bridge mode modem, well accommodating VDSL2
(Very-high-data-rate Digital Subscribe Loop) technologies to extend
Ethernet service over single-pair phone line. Supporting both symmetric
and asymmetric transmission, it can reach up to 100/75 Mbps bandwidth
(line rate) within 300M or 10/10 Mbps (line rate) for 1 Km long range
connections. By providing ultrahigh speed, VDSL2 LAN Extender makes
your telephone line achieve its best performance than before.
It has the advantage of minimum installation time (simply as plug-nplay)
and minimum expense by allowing video streaming and data to share the
same telephone pair without interference.
1.1 Features
Cost effective bridge function to connect two Ethernet LANs
Support flow control on Fast Ethernet port via PAUSE frame or
Back Pressure
IEEE 802.1Q VLAN tag transparent
Easy installation via simple plug-and-play
Selectable CPE and CO mode via DIP switch:

Two working modes are built in the same unit, which keep the
flexibility of installation and easy provision of service but lower
inventory of service provider.
Selectable fast and interleaved mode:
Fast mode guarantees a minimum end to end latency less than1
ms. Interleaved 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 m sec. Interleaved mode
is the default mode.
Selectable target data rate and target SNR margin:
User has the ability to select fixed SNR margin (9 dB) or fixed target
data rate. When fixed SNR margin is selected, the systems will
maintain the SNR margin at 9 dB across all usable loop length.
When fixed target data rate is selected, the system will lock the data
rate up to 50 Mbps/30 Mbps whenever the calculated SNR margin
is higher than 9 dB. This gives best system stability and is the
default mode.

2.1 Front Panel
This chapter shows the front panel and how to install the hardware.
Front panel can be separated into five parts from left to right:
(1) DIP switch
(2) RJ-45 connector for Ethernet
(3) LEDs for Ethernet
(4) LED for VDSL
(5) RJ-45 connector for VDSL
The RJ-45 is designed to connect to the Local Network with the
Unshielded Twisted Pair (UTP) cable.

2.1.1 Switches
The following table describes the DIP Switches’ setting:
Pin 1 Pin 2 Pin 3 Pin 4
Side Channel Rate Limit SNR
Off CO Interleave Symmetric 9dB
On CPE Fast Asymmetric 6dB
Pin 1: CO, CPE switch
GO: LAN Extender acts as Central Office (CO) side.
GPE: LAN Extender acts as Customer Premise Equipment (CPE) side.
Pin 2: Impulse noise protection
Interleave mode: Provides communication protection for up to 250ms
impulse noise with latency less than 6 ms.
Fast mode: Direct data transmission with latency less than 1 ms.

Pin 3: Band Plan
Symmetric: Support the band plan G.997 and provide the symmetric
transmission on both down stream and upstream.
Asymmetric: Provides highest line rate in short range in asymmetric
mode.
Pin 4: General protection
9dB: Better channel noise protection with SNR up to 9 dB
6dB: Original channel noise protection with 6 dB SNR
