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 Concentrator (VDSL switches), 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. The VDSL solution provides multicast, Layer 2 quality of
service (QOS), Link Aggregation (LACP) dynamic trunking group, security,
GVRP, IGMP for VOD (Video on demand) and SNMP RMON management
and Web-based Switch network management.
The VDSL Concentrator is a 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.
The Concentrator uses the phone line networking technology endorsed by
the VDSL, and the Concentrator utilizes the already existing telephone wire

APPLICATION FOR HOME NETWORKING
The 10Mbps Converter is used to connect any device equipped with a
standard 10/100Mbps Ethernet port to a VDSL LAN.
The Converter 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 Converter 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 Converter uses a frequency division multiplexing approach that
enables standard telephone wiring to simultaneously carry POTS voice,
ISDN and VDSL signals without any of the services impacting each other.

Appendix C: Troubleshooting
Diagnosing the Converter’s Indicators
The Converter 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: Defective External power supply
Solution: Cheek the power plug by plugging in another that is
functioning properly. Check the power cord with another
device. If these measures fail to resolve the problem,
have the unit power supply replaced by a qualified
distributor.
2. Symptom: Link indicator does not light up (green) after making a
connection.
Cause: Network interface (e.q, a network adapter card on the
attached device), network cable, or switch port is
defective.
Solution:
2.1 Power off them Power on the VDSL Modem.
2.2 Verify that the switch and attached device are powered on.
2.3 Be sure the cable is plugged into both the switch and
corresponding device.
2.4 Verify that the proper cable type is used and its length does
not exceed specified limits.
2.5 Check the converter on the attached device and cable
connections for possible defects.
2.6 Replace the defective converter or cable if necessary.
2.7 Verify the VDSL switch and VDSL Modem during the same
speed mode. You can select VDSL Speed mode by 10 Mbps.
Only same speed mode can link and work. VDSL default
translation mode is 10 Mbps.

VDSL CPE CONVERTER USER’S MANUAL VER. A.5

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. 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.
Transmission 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

VDSL CPE CONVERTER USER’S MANUAL VER. A.5
18
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.
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
