Chapter 2. Installing the Bridge
2.1 Hardware Installation
This chapter describes how to install the bridge and establish the networ connections. The NV-320SE 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 54V 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 5a UTP/STP or above for 1Gbps,
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 Switch 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-320SE 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 the 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-202/NV-500/NV-320SE (CO side) to
NV-320SE(CPE side) by single pair phone cable . Ta e note that NV-320SE 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)

 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.
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-320SE is powered on.

Appendix A: Cable Requirements
A.1 Ethernet Cable
A CAT 3~7 UTP (unshielded twisted pair) cable is typically used to connect the Ethernet device to the Modem. A: 10/100TX
cable often consists of four pairs of wires, two of which are used for transmission. The connector at the end of the 10/100TX
cable is referred to as a RJ-45 connector and it consists of eight pins. The Ethernet standard uses pins 1, 2, 3 and 6 for
data transmission purposes. (Table A-1 10/100TX)
B: 1000TX cable often consists of four pairs of wires, all of which are used for transmission. The connector at the end of the
1000TX cable is referred to as a RJ-45 connector and it consists of eight pins. The Ethernet standard uses pins 1, 2, 3, 4, 5
and 6 for data transmission purposes. (Table A-1 1000TX)
