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.
Foreword The VDSL Modem is an Ethernet to VDSL 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.

1.Unpacking Information Check List Carefully unpack the package and check its contents against the checklist. Package Contents • • • • • • Ethernet to VDSL Modem Four plastic feet User Manual AC to DC Power Adapter RJ-45 cable RJ-11 cable Please inform your dealer immediately for any missing, or damaged parts. If possible, retain the carton, including the original packing materials, Use them to repack the unit in case there is a need to return for repair.
2.Installing the Modem Hardware Installation This chapter describes how to install the Modem and establishes network connections. You may install the Modem on any level surface (e.q, a table or shelf). However, please take note of the following minimum site requirements before you begin. Stick the 4 plastic feet at the bottom.
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-11) 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 RJ-11/RJ-45 Ports 1.The Modem’s RJ-11 ports support the transmission of data up to 10Mbps 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 1.9KM (6000 feet) between the two farthest points. (Figure 1.0). 2.
3.The RJ-11 port support 10 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 FCC standard. Notes: 1.Be sure each twisted-pair cable (RJ-45) does not exceeds 100 meters (333 feet). 2.
3.Hardware Description This section describes the important parts of the Modem. It features the front indicators and rear connectors. Front Indicators The following figure shows the front panel. Figure Chapter 2.2 Front Indicators Three LED indicators.
Front Indicators LED Description and Operation The Modem has three LED indicators. LEDs Status Ready (Ready LED) Steady Green Ethernet (Ethernet LED) Steady Green Flashing (LINK/ACT) VDSL (VDSL LED) Steady Green Descriptions It will light up (ON) to show that the product is power good, and system reset OK. Each RJ45 station port on the Ethernet is assigned an LED light for monitoring port “Good Linkage”.
Rear Panel The following figure shows the rear connectors Figure Chapter 2.3 Rear Connectors Modem Rear Side Connectors Connectors Line Phone LWD Ethernet Description For connecting to the RJ-11 wall jack Using a RJ-11 cable For connecting to the telephone or Fax or ISDN modem For recovering LINK status between CPE & CO For connecting to a Ethernet equipped device Power On 1. Check the Modem is properly connected 2.
4.Applications 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 have 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.
Appendix A: Cable Requirement 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.
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.

Appendix C: Troubleshooting Diagnosing the Modem’s Indicators The Modem can be easily monitored through its comprehensive panel indicators. These indicators assist the network manager in identifying problems the hub may encounter. This section describes common problems you may encounter and possible solutions 1. Symptom: Ready indicator does not light up (green) after power on. Cause: Symptom External power supply Solution: Check the power plug by plugging in another that is functioning properly.
2.7 Verify the VDSL switch and VDSL Modem during the same speed mode. You can select VDSL Speed mode by 10 Mbps. 2.8 speed mode can link and work. VDSL default translation mode is 10 Mbps. 3. Symptom: VDSL Link can not be established. Cause: Rusted phone wire, not standard 24 gauge phone wire, not twisted-pair phone wire, Wrong speed mode. Solution: Check if speed of CO and CPE is in the same speed mode else please increase interleaver depth value to 8 or above. 4.

System Diagnostics 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.
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.
Appendix DLink Recover Procedures Operating Procedures: 1. Power on VDSL CO, start the speed change program, change speed mode to 4/1Mbps. 2. Connect phone line between VDSL CO & VDSL CPE. 3. Push still Link Recover Button of VDSL CPE and power on VDSL CPE. 4. Wait for 5 seconds, then release Link Recover Button. 5. Now, VDSL CPE speed mode has changed to 4/1Mbps mode, wait until VDSL CO & VDSL CPE establish link {You can see that both VDSL LEDs(CO & CPE) are steadily on}. 6.
Appendix EAccessories-Bracket Two Brackets The brackets are specially designed to fix the VDSL Modem on the table to avoid someone to freely take it away, like in hotel rooms, internet café or other public areas where providing the internet service. It is suggested to use with the wooden table. This is an optional accessory, please contact with your local dealer for further service. Note: Do not install plastic feet at the bottom of the VDSL CPE Modem when using brackets.
