Chapter 1 Introduction
Proscend 100 VDSL LAN Extender is a long reach Ethernet media converter with one Ethernet port (RJ-45 connector) and one VDSL port (RJ-45 connector) 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 ultra-high speed, Proscend VDSL 100 LAN Extender makes your telephone line achieve its best performance than before. It has the advantage of minimum installation time (simply as plug-n-play) 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 LAN  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.

Chapter 2 Hardware Installation
This chapter shows the front panel and how to install the hardware.
2.1 Front Panel
Please see the side view below configure 2.1: 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) LEDs for VDSL (5) RJ-45 connector for VDSL
1. The RJ-45 is designed to connect to the Local Network with the Unshielded
Twisted Pair (UTP) cable. The LEDs on top of RJ-45 connector show the status

2. The following table describes the DIP Switchs’ 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.
