VDSL Point to Point Solution
The NVF-200LS/Rver.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-200Rver.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 modem or IP DSLAM over auto speed or fix speed function.
Therefore, NVF-200LS/Rver.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.

2. Installing the Modem
Hardware Installation
This chapter describes how to install the modem and establishes network connections and may install the modem 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.
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 5V/1A or above
•The modem should be located in a cool dry place, with at least 10cm/4in of space at the front and back for
ventilation.
•Place the modem out of direct sunlight, and away from heat source or area with a high amount of
electromagnetic interference.
•Check if the network cables and connectors needed for installation are available.

General Rules
Before making any connections to the modem, please note the following rules:
•Ethernet Port (RJ-45)
All network connections to the modem 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 phone wiring.
•We do not recommend using 28 gauge or above phone line.
Connecting the Modem
The modem 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.
The RJ-11 line port is used to connect to the RJ-11 modular socket (wall outlet) that is connected to the VDSL 4-Band
CPE modem side (Point to point solution).
The RJ-11 phone port of the modem can be connected to a telephone for making calls
.

Connecting the RJ-11 / RJ-45 Ports
1. The modem’s RJ-11 ports supports max distance 1.9km at 5M/5M or max speed 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 1).

2. NVF-200LS/R modem 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. The RJ-11 port support max 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, 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 modem.
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 modem 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-200Rver.S power on.

3. Hardware Description
This section describes the important parts of the modem. It features the front panel, side panel and rear connectors.
Front Panel
The figure shows the front panel. (Figure 2)
Figure 2 Front Panel
At a quick glance of the front panel, it is easy to tell if the CO modem has power, if it has signal from its Ethernet RJ-45
port and if there is phone line signal on RJ-11 port.

Side Panel
The following figure shows the DIP switch connection. (Figure 4)
Figure 4 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 5 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.

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 NVL-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:
5M/5M mode within 1.9km (6333 ft.)
15M/15M mode within 1.3km (4333 ft.)
25M/25M mode within 800m (2666 ft.)
With the above phone cable limit based on without PBX noise.
Note:
We recommend phone cable that must meet Cat 3 standard or above and without clustering, otherwise the above
guarantee will be void.

Appendix A: Cable Requirements
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 RJ-45 connector and it consists of eight pins. The Ethernet standard uses pins 1, 2, 3
and 6 for data transmission purposes. (Table 4)

Standard telephone wire of any gauge or flat type, 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 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 6)

The Aand 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 5)
