Chapter 1 Introduction
TEX-100 Ethernet Extender is a high-speed Ethernet Extender with one Ethernet port
(RJ-45 connector) and one VDSL port (RJ-45 connector). It is a bridge mode modem,
well accommodating VDSL2 (Very-high-data-rate Digital Subscriber Loop) technology to
extend Ethernet service over single-pair phone line. It is compliant to ITU-T G.993.2
standard and supports VDSL2 30a profile that features 100Mbps of symmetric data rate
over the existing copper wires. Supporting both symmetric and asymmetric
transmission, it can reach up to 100/100 Mbps bandwidth (line rate) within 300M or
10/10 Mbps (line rate) for 1 Km long range connections. By providing ultra-high speed,
the TEX-100 Ethernet 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.
TEX-100 Ethernet Extender delivers everything needed to quickly deploy a high-speed
IP-based network for providing high-speed Internet access, video-on demand services
and voice services. The resulting compact, cost-effective form factor offers Systems
Integrators, small business owners an attractive Long Reach Ethernet solution.

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 VDSL2 profile mode (17a or 30a):
Support up to VDSL2 30a profile to ensure high data rate.
Selectable target band plan:
Symmetric: Support the band plan G.997 and provide the symmetric
transmission on both downstream and upstream.
Asymmetric: Provides highest line rate in short range in asymmetric mode.
Selectable target SNR margin
Compatible with the 724M/708M DSLAM & third party DSLAM.
Compatible with the 2U 19-inch, 17-slot chassis.

Chapter 2 Hardware Installation
This chapter shows the front panel and how to install the hardware.
2.1 Front Panel
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 below:
2.
3. The following table describes the DIP Switches’ setting.

9
Pin 1: OT, RT switch
OT: LAN Extender acts as Central Office (CO) side.
RT: LAN Extender acts as Customer Premise Equipment (CPE) side.
Pin 2: Impulse noise protection
30a: High Speed Mode. Provides communication protection for up to 250ms impulse
noise with latency less than 6 ms.
17a: Long Reach 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 downstream 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.
4. The following table describes the LEDs’ function of the product.
2.2 Rear Panel
The DC Jack on the rear panel can be connected to power supply adaptor with the DC
input.
