VDSL Point to Point Solution
The VDSL (Very High Data Rate DSL) networking solution delivers cost-effective, high-performance broadband access to multiunit
buildings (hotels, apartment, and multi-tenant unit office buildings) and enterprise campus environments such as manufacturing,
educational campuses, and medical facilities. VDSL technology dramatically extends Ethernet over existing Category 1/2/3 wiring at
speeds 10Mbps (full duplex) and distances up to 1200 meters. The VDSL technology delivers broadband service on the same lines as
Plain Old Telephone Service (POTS), digital telephone, and ISDN system. In addition, VDSL supports modes compatible with
asymmetric digital subscriber line (ADSL), allowing service providers to provision VDSL to buildings where broadband services already
exist.
The VDSL solution includes VDSL IP DSLAM (VDSL switches), VDSL CO(Point to Point), and VDSL Modem for Customer Premise
Equipment (CPE) device.
The VDSL solution delivers everything needed to quickly deploy an Ethernet-based network with the performance required to deliver
high-speed Internet access at much greater distances and drive services like IP telephony and audio/video streaming. With this
technology, a broad range of customers can benefit from lower operating costs and rapid deployment. This solution provides a RS-232C
console port for monitoring
VDSL status and to configure speed.
This device is a CO side solution, and bridge between external Internet backbone through a router for IP sharing and the building
110D telephone rack or telephone box. It utilizes the available telephone wire to enable high-speed Internet access to building residents.
VDSL Modem uses the phone line networking technology endorsed by the VDSL, and utilizes the already existing telephone wire to deliver 4/1,
5/10/15 Mbps Internet access on each RJ-11 port.
This gives users a low-cost, end-to-end solution and eliminates the need to train installation teams on multiple systems.

Foreword
This is an Ethernet to VDSL CO side adapter that enables high speed internet access to building residents, campuses students and
hotel guests by connecting Ehternet equipped computers, set-top box or any internet access device to the existing telephone wires.
The VDSL Modem uses the phoneline networking technology endorsed by the VDSL, an association of industry-leading companies for
in– networking focus on the existing telephone wire.
The Modem utilizes the already existing telephone wire to deliver 10Mbps internet access with no interference on the existing telephone
service. It allows user to make calls while access the internet on the same wire simultaneously. It ev en allows staying connected 24
hours on internet connections, thus, eliminating dial up prior to internet access.
The Modem is simple to install and use. One RJ-45 Ethernet connects to a Router, Ethernet Switch or to LAN card. The RJ11 ports
available to connect to any existing modular phone jack.
There are two RJ-11 jack on the Modem to provide a phone extensions.

requirements, sufficient physi c al space, and proximity to other network devices that are to be connected.
V erify 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 sour ces or areas with a high amount of electromagnetic
interference.
•
Check if network cables and connectors needed for installation are available
5
General Rules
Before making any connections to the Modem, 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-1 1)
All Home network connections to the RJ-11Port made using 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. You can also connect to another
compatible Modem to an RJ-45 port on the other device.
The RJ11 Line port is used to connect to the wall RJ-11 modular socket which is connect to VDSL CPE Modem side (Point to point
solution)
The RJ11 Phone port of the Modem can connected to a telephone and a computer sharing one telephone wire for making calls and
accessing the internet at the same time
6
Connecting the RJ-11/RJ-45 Ports
1. The Modem’s RJ-11 ports support the transmission of data up to 4/1, 5/10/15Mbps across existing phone wiring, without interfering with
standard voice transmissions, easy-to-use 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
1.9/1.5/1.2/1km (depend on speed) between the two farthest points. (Figure 1.0).
2. VDSL CO Modem has embedded Splitter between every VDSL side (Line) and POTS (Phone) side. It permit you can delivers broadband
service on the same lines as Plain Old Telephone Service (POTS), PBX, ISDN traffic and VDSL Signal.

3.The RJ-11 port support 4/1,5/10/15 Mbps connections. When inserting a RJ-11 plug, be 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 exceeds 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 cable for Cable Modem or Router connections to avoid any confusion or inconvenience in the
future when you upgrade attached to high bandwidth devices.

APPLICATION FOR HOME NETWORKING
The 10Mbps Modem is used to connect any device equipped with a standard 10/100Mbps Ethernet port to a VDSL LAN.
The Modem has been designed to operate on the telephone wire installed in homes throughout the world. They utilize the same
modular patch cords and connectors commonly used for telephones.
To install the Modem or to access the Internet, you simply plug into your existing telephone jacks just like you would a telephone
modem or a fax machine. There is no need for special splitters, terminators or filters. In fact, there is no need to add or modify the
home telephone wiring at all.
The Modem uses a frequency division multiplexing approach that enables s tandard telephone wiring to simultaneously carry POTS
voice, ISDN and VDSL signals without any of the services impacting each ot her.

Power and Cooling Problems
If the POWER indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power
cord, or internal power supply as explained in the previous section. However, if the unit power is off after running for a while, check
for loose power connections, power losses or surges at the power outlet, and verify that the fan on back of the unit is unobstructed
and running prior to shutdown. If you still cannot isolate the problem, then the internal power supply may be defective. In this case,
contact your dealer.
Installation
Verify that all system components have been properly installed. If one or more components appear to be malfunctioning (e.g., the
power cord or network cabling), test them in an alternate environment where you are sure that all the other components are
functioning properly.
T ransmission Mode
The default method of selecting the transmission mode for RJ-45 ports is 10/100 Mbps ETHERNET, for RJ-11 port are 10Mbps
VDSL. Therefore, if the Link signal is disrupted (e.g., by unplugging the network cable and plugging it back in again, or by resetting
the power), the port will try to reestablish communications with the attached device via auto-negotiation.
If auto-negotiation fails, then communications are set to half duplex by default. Based on this type of industry-standard connection policy, if
you are using a full-duplex device that does not support auto-negotiation, communications can be easily lost (i.e., reset to the
wrong mode) whenever the attached device is reset or experiences a power fluctuation. The best way to resolve this problem is to
upgrade these devices to a version that support Ethernet and VDSL.
42
Physical Configuration
If problems occur after altering the network configuration, restore the original connections, and try to track the problem down by
implementing the new changes, one step at a time. Ensure that cable distances and other physical aspects of the installation do not
exceed recommendations.
System Integrity
As a last resort verify the switch integrity with a power-on reset. Turn the power to the switch off and then on several times. If the
problem still persists and you have completed all the preceding diagnoses, then contact your dealer.
