Foreword: VDSL2 solution
Attention:
Be sure to read this manual carefully before using this product. Especially Legal Disclaimer, Statement
of Conditions and Safety Warnings.
NV-202G is a 2 x 10/100/1000Mbps LAN over VDSL2 extender, that provide an economical solution for point to point application. It is
compliant with ITU-T G.993.2 VDSL2 standard, and G.998.4 INP standard. NV-202G supports a maximum bandwidth up to 160Mbps
symmetric and G.INP in VDSL2 Profile (17a/30a band profile) solution, and also supports both Master (CO) and Slave (CPE) modes
selectable by DIP Switch, as well as support UPBO / DPBO/ G.INP for preventing noise disturbance, NV-202T is also support
vectoring function for Telecom requirements.
Since VDSL2 has the characteristic of higher bandwidth over shorter distances, the ideal architecture for Telecoms is to use fiber
optic lines as the bac bone and a VDSL2 line as the last mile into the home or office. With outstanding throughput, the NV-202G can
complement a fiber networ to offer the best solution for delivering Triple play (Video/Voice/Data) or point to point application.
Caution:
The NV-202G is for indoor applications only. This product does not have waterproof protection, please do not use in outdoor
applications.

Chapter 2. Installing the LAN Extender
2.1 Hardware Installation
This chapter describes how to install the bridge and establish the networ connections. The NV-202G may be installed
on any level surface (e.g. a table or shelf or rail). However, please ta e note of the following minimum site requirements
before one begin.
2.2 Pre-installation Requirements
Before you start the actual hardware installation, ma e sure you can provide the right operating environment, including
power requirements, sufficient physical space, and proximity to other networ devices that are to be connected.
Verify the following installation requirements:
 Power requirements: DC 12V /1A power source.
 The bridge should be located in a cool dry place, with at least 10cm/4in of space at the front and bac for
ventilation.
 Place the bridge away from direct sunlight, heat sources, or areas with a high amount of electromagnetic
interference.
 Chec if the networ cables and connectors needed for installation are available.
 Do not install phone lines strapped together with AC power lines, or telephone office line with voice signal.
 Avoid installing this device with radio amplifying station nearby or transformer station nearby.

2.3 General Rules
Before ma ing any connections to the bridge, please note the following rules:
 Ethernet Port (RJ-45)
All networ connections to Ethernet port must be made using Category 5 UTP/STP or above for
100/1000Mbps, Category 3, 4 UTP for 10Mbps.
No more than 100 meters of cabling may be use between Ethernet switch or HUB and an end node.
 VDSL2 Port (RJ-11)
All networ connections to the RJ-11port must use 24~26 gauge with twisted pair phone wiring.
We do not recommend the use of the telephone line 28 gauge or above.
The RJ-11 connectors have six positions, two of which are wired. The router uses the center two pins. The
pin out assignment for these connectors is presented below.
Please note that the line port is no polarity, therefore user can reverse the two wires of the phone cable
when installed.

 External Splitter
NV-202G support both POTS and ISDN PBX, and depending on using an external splitter, ma e sure that you
are using one that is compatible with the interface you want to use.
2.4 Connecting the LAN Extender
The bridge has two Ethernet ports which support connection to Ethernet operation. The devices attached to these
ports must support auto-negotiation or 10Base-T or 100/1000Base-TX unless they will always operate at half duplex.
Use any of the Ethernet ports to connect to devices such as Monitor system, Server, Switch, bridge or router.
Notes:
1. The RJ11 Line port is used to connect the telephone that is connected to VDSL2 Master (CO) and Slave (CPE)
both NV-202G (Point-to-Point solution).
2. The Master (CO) mode device must be interconnected to the Slave (CPE) mode device over copper wire. Please
note both NV-202G interconnecting cannot config the same mode, please confirm the DIP switch config before
both NV-202G interconnecting.

2.5 Connecting the RJ-11 / RJ-45 Ports
 The line port has 2 connectors: RJ-45 and terminal bloc . It is used to connect with NV-202G(Master / CO) using a single pair
phone cable to NV-202G(Slave / CPE) bridge side (point to point solution). Ta e note that NV-202G line port RJ-11 and terminal
bloc cannot be used at the same time. Either RJ-11 port is connected or terminal bloc is connected using straight connection
(Figure 2.4) or cross-over connection (Figure 2.5)

 When inserting a RJ-11 plug, ma e sure the tab on the plug clic s into position to ensure that it is properly seated.
 Do not plug a RJ-11 phone jac connector into the Ethernet port (RJ-45 port). This may damage the bridge. Instead, use only
twisted-pair cables with RJ-45 connectors that conform to Ethernet standard.

2 x Giga Lan over VDSL2 extender USER’S MANUAL Ver. A3

Notes:
1. Be sure each twisted-pair cable (RJ-45 ethernet cable) does not exceed 100 meters (333 feet).
2. We advise using Category 5~7 UTP/STP cables for Cable bridge or Bridge connections to avoid any confusion
or inconvenience in the future when you attached to high bandwidth devices.
3. Use 24 ~ 26 gauge twisted pair phone wiring, we do not recommend 28 gauge or above.
4. Be sure the phone cable has been installed before NV-202G is powered on.

2.6 NV-202G Application
The bridge’s line port supports 100Mbps for data service across existing phone wiring. It is easy-to-use which do not request
installation of additional wiring. Every modular phone jac in the home can become a port on the LAN. Networ ing devices can be
installed on a single telephone wire that can be installed within suitable distance (depends on speed) (Figure 2.6)
