Foreword: VDSL Point to Point Solution
Attention:
Be sure to read this manual carefully before using this product. Especially Legal Disclaimer, Statement
of Conditions and Safty Warnings.
The NVF-200LS/R ver.S works as Ethernet to/from VDSL subscriber-site conversion bridge. The NVF-200LS/Rver.S uses
QAM-based 4-band VDSL technology which supports max distance 1.9km (6333 ft.) at 5M/5M or 1.3km (4333 ft.) at 15M/15M, or
800m (2666 ft.) at 25M/25M symmetrical data service. The NVF-200R ver.S also works with NVF-800S/NVF-2400S VDSL IP
DSLAM, together to form a cost-effective solution for services such as remote lecturing, telemedicine, video conferencing,
Video-on-Demand (VOD), IP-TV, Internet access, and various high-speed data applications.
The front-panel provides LED indicators of system and interface status. The built-in POTS/ISDN splitter allows a standard POTS
phone or ISDN device to be connected. Full or half-duplex mode of LAN operations is automatically sensed and configured. VDSL
link rates are configured by local bridge or IP DSLAM over auto speed or fix speed function.
Therefore, NVF-200LS/R ver.S supports plug & play operations on the subscriber-site and can do auto and manual selection of the
data speed. An ideal solution for delivering cost-effective, high-performance broadband/multimedia services to Multi-Dwelling Units
(MDU) and Multi-Tenant Units (MTU) such as hotels, campuses and hospitals environments.

Chapter 2. Installing the Bridge
2.1 Hardware Installation
This chapter describes how to install the bridge and establishes network connections and may install the bridge on any
level surface (e.g. a table or shelf). However, please take note of the following minimum site requirements before one
begin. Stick the 4 rubber feet at the bottom to avoid scratches.
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 5-12V / 1A or above
•The bridge should be located in a cool dry place, with at least 10cm/4in of space at the front and back for
ventilation.
•Place the bridge 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 station nearby or transformer station nearby.
•Please note NVF-200 internal splitter, can pass through voice spectrum is 0KHz ~ 630KHz.

2.3 General Rules
Before making any connections to the bridge, please note the following rules:
•Ethernet Port (RJ-45)
All network connections to the bridge Ethernet port must be made using Category 5 UTP 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.
•VDSL Port (RJ-11)
All Home 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 24 gauge below or 26 gauge above.
2.4 Connecting the Bridge
The bridge has one Ethernet port which support connection to Ethernet operation. The devices attached to these ports
must support auto-negotiation or 10Base-T OR 100Base-TX unless they will always operate at half duplex. Use any of
the Ethernet ports to connect to devices such as NIC, Switch, bridge or router.
Note:
1.The RJ11 Line port is used to connect to the wall RJ-11 modular socket (outlet) that is connected to VDSL 4-Band
CPE bridge side (Point to point solution).
2.The RJ11 Phone port of the bridge can be connected to a telephone for making calls.

NVF-200LS/R ver.S 4 Band VDSL CO/CPE Bridge USER’S MANUAL Ver. B.4
10
2.5 Connecting the RJ-11 / RJ-45 Ports
1. The bridge’s RJ-11 ports supports max distance 1.9km at 5M/5M or max rate 25M/25M symmetrical and distances
up to 800m data service across existing phone wiring, without interfering with standard voice transmissions,
easy-to-use which do not require installation of additional wiring. Every RJ-11 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 span within
1.9km or 800m (depends on speed) between the two farthest points. (Figure 2.1)
Figure 2.1 VDSL Point-to-Point application

NVF-200LS/R ver.S 4 Band VDSL CO/CPE Bridge USER’S MANUAL Ver. B.4
11
2. NVF-200LS/R bridge has an embedded splitter between every VDSL side (Line) and POTS (Phone) side. It permits
one to deliver broadband service on the same lines as Plain Old Telephone Service (POTS), PBX, ISDN traffic and
VDSL Signal.
3. When inserting a RJ-11 plug, make sure the tab on the plug clicks into position to ensure that it is properly seated.
4. Do not plug a RJ-11 phone jack 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) does not exceed 100 meters (333 feet).
2. RJ-11 port use 24 ~ 26 gauge with twisted pair phone wiring.
3. We advise using Category 3 ~7 cables for Cable bridge or Router connections to avoid any confusion or
inconvenience in the future when you attached to high bandwidth devices.
4. Be sure phone cable has been installed before NVF-200LS and NVF-200R ver.S powered on.

3.1 Front Panel
The figure shows the front panel. (Figure 3.1)
Figure 3.1 Front Panel
Tip:
At a quick glance of the front panel, it is easy to determine if the CO or CPE bridge has power, if it has
signal from its Ethernet RJ-45 port and if there is phone line signal on RJ-11 port.

3.4 Side Panel
The following figure shows the DIP switch connection. (Figure 3.3)
Figure 3.3 Side panel
At quick glance, it is easy to see that the DIP switch pin 1 is switch ON where it is in auto-speed and that is also the
default mode. (Figure 3.4)
Figure 3.4 DIP switch setting

To set the data speed to 25Mbps simply switch ON the pin 2 while the other pins are switch OFF. To change it to
15Mbps, switch ON the pin 3 while the other pins are switch OFF, for 5Mbps switch on the pin 4 while other are switch OFF.
Remember that no two pins can be activated at the same time or it will result in error and for data speed of 5Mbps. Table
shows the summary of DIP switch configuration. (Table 3-3)

Chapter 4. Firmware Description
Auto and manual data speed selector description:
NVF-200LS/R is a 4band VDSL solution which supports real plug & play and can do auto and manual selection of the
data speed, the setting of the data speed depends on the phone cable length limit, they can support 5M/15M/25M
symmetrical data service but depends on installation environment. If NVF-200LS try to link at 25Mbps data speed but
fails to do so then NVF-200LS data speed must be lower due to the limitation of the phone cable length. If the cable
length is unsure, then auto selection of the data speed at the default setting is recommended. Power must be unplug
before changing of data speed then powered on and wait for VDSL to link again at the correct data speed function.
Speed mode limitation:
1. 5M/5M mode within 1.9km (6333 ft.)
2. 15M/15M mode within 1.3km (4333 ft.)
3. 25M/25M mode within 800m (2666 ft.)
Tip:
With the above phone cable limit based on without PBX noise.
Note1:
We recommend phone cable that must meet Cat. 3 standard or above and without clustering, otherwise the above
guarantee will be void.
Note2:
The performance data above is for reference only, the actual distance will vary on the quality of the copper wire and
environment factors. We recommend using 24~26 gauge and Cat. 3 standard or above phone wiring.

Appendix A: Cable Requirements
A.1 Ethernet Cable
A CAT 3, 4 or 5 UTP (unshielded twisted pair) cable is typically used to connect the Ethernet device to the modem. A
10Base-T cable often consists of four pairs of wires, two of which are used for transmission. The connector at the end of the
10Base-T cable is referred to as an 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)
