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-202P is a Long Reach Ethernet Extender with PoE equipped with two 10/100Mbps Ethernet ports with power injector. It delivers
data and electrical power to access points using standard Category 5 Ethernet cable that provide an economical solution for
commercial-grade applications.
Operators in various enterprises will now be able to deploy PoE devices in any service location, install networ security cameras,
wireless access point security / VOIP, or access control systems in any place where you have basic wire connectivity.
The NV-202P also supports both central office (CO) and customer-premises equipment (CPE) modes selectable through DIP Switch.
Compliant with ITU-T G.993.2 VDSL2 standard, the NV-202P supports a maximum bandwidth of up to 100Mbps symmetric in VDSL2
solution. 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-202P
can complement a fiber networ to offer the best solution for delivering Triple play(Video/Voice/Data) or home entertainment
services.
Caution:
The NV-202P is for indoor applications only. This product does not have waterproof protection, please do not use in outdoor
applications.

Chapter 2. Installing the Bridge
2.1 Hardware Installation
This chapter describes how to install the bridge and establish the networ connections. The NV-202P 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.
If you experience any error or problem, please be sure, Netsys will care for you and the problem. Please contact your local
dealer for support. If you are told to send the device for RMA and repair, ALWAYS ship the whole device with power
supplies.
Verify the following installation requirements:
 Power requirements: DC 48V power.
 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 the bridge Ethernet port must be made using Category 5 UTP/STP or above for
100Mbps, Category 3, 4 UTP for 10Mbps.
No more than 100 meters of cabling may be use between the MUX 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
Our devices support both ISDN interfaces U(2w) and S/T(4w). When 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 Bridge
The bridge has two Ethernet ports which support connection to Ethernet operation and PoE function. The devices attached to these
ports must support auto-negotiation or 10Base-T or 100Base-TX unless they will always operate at half duplex. NV-202P fast
Ethernet port is used to connect to external power splitter(PoE) or build in power splitter of networ ing devices such as IP CAM,
VOIP, wireless AP, sensor scanner or other power splitter(PD side) more than 30W.
Notes:
1. The RJ11 Line port is used to connect to telephone that is connected to VDSL2 CO and CPE bridge
(Point-to-point solution).
2. The Slave device (CPE) must be connected to the Master device (CO) through the telephone wire. The Slave
cannot be connected to another Slave, and the Master cannot be connected to another Master. Please confirm the
DIP switch status before the lin is established.

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 from NV-202P (CO) using single pair phone cable
to NV-202 (CPE) side (point to point solution). Ta e note that NV-202P line port 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)
Figure 2.4 NV-202P line ports straight connection Figure 2.5 NV-202P line ports crossover connection
 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.

NV-202P Long Reach Ethernet Extender with PoE User’s Manual Ver. A
11
Notes:
1. Be sure each twisted-pair cable (RJ-45 Ethernet cable) does not exceed 100 meters (333 feet).
2. We recommend use Category 5~7 UTP/STP cables for Cable bridged 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-202P is powered on.

2.6 VDSL2 bridge Application
1. User can use NV-202 bridge (CO mode) to connect NV-202P bridge (CPE mode), or use NV-202P bridge (CO mode) to connect
NV-202 bridge (CPE mode) that to do a variety of applications. The bridge’s line port supports 100Mbps maximum for data service
across existing phone wiring. It is easy-to-use which do not require 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)

2. If user need use over 1.5 m cable length and also need bigger bandwidth application, such as connect to ip camera. User can
use NV-202P (CO mode) and NV-202 (CPE mode) to achieve the IP surveillance for long distance application. (Figure 2.7)
