Foreword: VDSL2 Router solution
Attention:
Be sure to read this manual carefully before using this product. Especially Legal Disclaimer, Statement
of Conditions and Safety Warnings.
Netsys' NV-720R is a management of the VDSL2 CPE router that leverages the extraordinary bandwidth promise of VDSL2 (max.
100Mbps symmetric) technology, the next step in the delivery of new high-speed Internet applications in commercial environments.
Quick, easy, economical to install and maintain, the NV-720R works over existing copper wire infrastructure. NV-720R is a CPE
(Customer Premise Equipment) device. And compitable with the NV-802S(8Ports VDSL2 IP DSLAM) and NV-700L (VDSL2 CO
Router).
Netsys NV-720R will allow operators worldwide to compete with cable andsatellite operators by offering services such as HDTV,
VOD, videoconferencing, high speed Internet access and advanced voice services including VoIP, over a standard copper
telephone cable.Netsys NV-720R is seen by many operators as an ideal accompaniment to a FTTP rollout, where for instance fiber
optic is supplied direct to an apartment block and from there copper cable is used to supply residents with high-speed VDSL2.
Caution:
The NV-720R is for indoor applications only. This product does not have waterproof protection, please do not use in outdoor
applications.

Chapter 2. Installing the Router
2.1 Hardware Installation
This chapter describes how to install the router, and establish the network connections. The NV-720R may be installed
on any level surface (e.g. a table or shelf). However, please take note of the following minimum site requirements
before you begin. The NV-720R has 2 pre-installed rubber feet.
2.2 Pre-installation Requirements
Before you start the actual hardware installation, make sure you can provide the right operating environment, including
power requirements, sufficient physical space, and proximity to other network devices that are to be connected.
Verify the following installation requirements:
•Power requirements: DC 12 V / 1A
•The router should be located in a cool dry place, with at least 10cm/4in of space at the front and back for
ventilation.
•Place the router away from direct sunlight, heat sources, or areas with a high amount of electromagnetic
interference.
•Check if the network 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 stations nearby or transformer stations nearby.
•Please note that the voice spectrum allowed by the NV-720R internal splitter is 0 KHz ~ 120 KHz.

2.3 General Rules
Before making any connections to the router, please note the following rules:
•Ethernet Port (RJ-45)
All network connections to the router Ethernet port must be made using Category 5 UTP/STP or above for
100 Mbps, 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 network 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. RJ-11 Pin out Assignments

2 NC Unused
3 DSL Used
4 DSL Used
5 NC Unused
6 NC Unused

2.4 Connecting the Router
The router has four Ethernet ports which support connection to Ethernet operation. The devices attached to these
ports must support auto-negotiation /10Base-T / 100Base-TX unless they will always operate at half duplex. Use any of
the Ethernet ports to connect devices such as Monitor systems, Servers, Switches, bridges or routers.
Notes:
1. The (RJ11) Line port is used to connect the telephone that is connected to VDSL2 CO and CPE router
(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.

NV-720R ADSL2+/ VDSL2 Modem Router USER’S MANUAL Ver. A.2

2.5 Connecting the RJ-11 / RJ-45 Ports
The line port has 1 connector: RJ-11. It is used to connect with NV-700L(CO) using a single pair phone cable to NV-720R(CPE)
bridge side (point to point solution). (Figure 2.1)
When inserting a RJ-11 plug, make sure the tab on the plug
clicks into position to ensure that it is properly seated.
Do not plug a RJ-11 phone jack connector into the Ethernet
port (RJ-45 port). This may damage the router. Instead, use
only twisted-pair cables with RJ-45 connectors that conform
to Ethernet standard.
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
making Bridge or Router connections to avoid any
confusion or inconvenience in the future when you attach
high bandwidth devices.
3. Use 24 ~ 26 gauge twisted pair phone wiring, we do not
recommend 28 gauge or above.
4. Be sure phone wire has been installed before the
NV-720R boot.

2.6 VDSL2 Application
The router’s line port supports up to 3km for data service across existing phone wiring. It is easy-to-use and do not requires
installation of additional wiring. Every modular phone jack in the home can become a port on the LAN. Networking devices can be
installed on a single telephone wire that can be installed within a suitable distance. (Figure 2.2)

2.6.1 Connect the NV-802S and the NV-720R to the Line
The objective for VDSL2 is to pass high speed data over a twisted pair cable. In the setup, connect NV-802S to NV-720R
through phone wire(24~26 AWG) or line simulator or any other hardware representation of a cable network, with or without noise
injection and crosstalk simulations.
2.6.2 Connect the NV-802S and the NV-720R to LAN Devices
In the setup, usually an Ethernet tester serves as a representation of the LAN side as well as a representation of the WAN side.
2.6.3 Run Demos and Tests
The Ethernet tester may send data downstream as well as upstream. It also receives the data in order to check the integrity of
the data transmission. Different data rates can be tested under different line conditions.

Before user installed power and device, please read and follow these essentials:
 Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the
wires are perpendicular at the intersection point.
Note:
Do not run signal or communications wiring and power wiring through the same wire conduit. To avoid interference, wires with
different signal characteristics should be routed separately.
 You can use the type of signal transmitted through a wire to determine which wires should be kept separate. The rule of thumb
is that wiring sharing similar electrical characteristics can be bundled together.
 You should separate input wiring from output wiring.
 We recommend that you mark all equipment in the wiring system.
