Foreword: VDSL Point to Point Solution
The NVF-400L/R utilizes Ethernet to/from VDSL subscriber-site conversion-bridge and uses QAM-based 4-band VDSL technology
which supports high bandwidth up to 25Mbps symmetrical data service.
The NVF-400L also works with NVF-200R or NVF-400R, 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 for 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 IP DSLAMs over a fix speed and auto speed function.
Therefore, NVF-400L/R supports auto speed and plug & play operations in the subscriber site to form an ideal solution for delivering
cost effective, high performance broadband/multimedia services to Multi-Dwelling Units (MDU) and Multi-Tenant Units (MTU)
environments such as hotels, campus, hospitals and telecom.
Attention:
Be sure to read this manual carefully before using this product. Especially Legal Disclaimer, Statement
of Conditions and Safty Warnings.
Caution:
The NVF-400 is for indoor applications only. This product does not have waterproof protection. Do not use in harsh environments
(Over temperature range: 0°C ~ 50°C (32°F ~ 122°F)).

Chapter 2. Installing the Bridge
2.1 Hardware Installation
This chapter describes how to install the bridge and establishes network connections. You 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
you begin. 2 rubber feet at the bottom are pre-installed 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 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 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-400 internal splitter, can pass through voice spectrum is 0KHz ~ 630KHz.

2.3 General Rules
Before making any connections to the bridge, 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 made using 24~26 Gauge with twisted pair phone wiring.
•We do not recommend using 28 Gauge or above phone line.
2.4 Connecting the Bridge
The bridge has four 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.
3.The console port is not available for use. It is use for engineering debug only.

2.5 Connecting the RJ-11 / RJ-45 Ports
1. The bridge’s RJ-11 ports supports maximum distance up to 1.9km at 5M/5M or maximum speed at 25M/25M
symmetrical with distances up to 800m data service across existing phone wiring without interfering with standard
voice transmissions, it is easy to use and does not require the installation of any 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 (depending on speed) between the two farthest points. (Figure
2.1)
Figure 2.1 NVF-400L/R application

NVF-400L/R 4 Band VDSL CO/CPE Bridge with 4 Ports Switch USER’S MANUAL Ver. A.5

2. NVF-400L/R bridge has embedded splitter between every VDSL side (Line) and POTS (Phone) side. It permits you
to deliver broadband service on the same lines as Plain Old Telephone Service (POTS), PBX, ISDN traffic and
VDSL Signal.
3. The RJ-11 port support maximum distance 1.9km at 5M/5M or max speed 25M/25M symmetrical and distances up
to 800m data service. When inserting a RJ-11 plug, be sure to 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 phone wiring, we do not recommend 28 gauge or above.
3. We advise using Category 3, 4, 5 cables for Cable Bridge or Router connections to avoid any confusion or
inconvenience in the future when you upgrade attached to high bandwidth devices.
4. Be sure phone cable has been installed before NVF-400L/R powered on.

Chapter 4. Firmware Description
Auto speed function description:
NVF-400L/R is a 4 band VDSL solution which supports auto speed function and real plug & play. It can support
5M/15M/25M symmetrical data service but depends on installation environment and cable limit length. It can also do auto
speed function while phone cable be re-plug in between NVF-400L and NVF-400R, or both be re-power on. NVF-400L will
try to link at 25M/25M mode first, if the link fails, it will auto speed down to 15M/15M mode, and if the link fails again, it will
auto speed down to 5M/5M, then stay on this mode until re-plug in phone cable or re-power on them, to restart auto speed
function again, both link up need one to three minutes which depend on phone cable length by auto-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)

A.2 Telephone wire
Standard telephone wire of any gauge or type-flat, twisted or quad is used to connect the Modem to the telephone network.A
telephone cable typically consists of three pairs of wires, one of which is used for transmission. The connector at the end of
the telephone cable is called an RJ-11 connector and it consists of six pins. POTS (plain old telephone services) use pins 3
and 4 for voice transmission.A telephone cable is shown below. (Figure A-4)

Figure A-4 Telephone cable
The A and B connectors on the rear of the Modem are RJ-11 connectors. These connectors are wired identically. The RJ-11
connectors have six positions, two of which are wired. The Modem uses the center two pins. The pin out assignment for
these connectors is presented below. (Table A-2)
