1.2 Introduction to Ethernet over VDSL2
Converter
PLANET’s state-of-the-art Ethernet-over-VDSL2 products
are based on two core networking technologies: Ethernet
and VDSL2 (Very-high-data-rate Digital Subscriber Line).
This technology offers the absolute fastest possible data
transmission speeds over existing copper telephone lines or
coaxial cables without the need for rewiring.
The VC-201/VC-202 Ethernet over VDSL2 converters has a
switching architecture with one RJ-45 10/100Mbps Ethernet
port and one symmetric Ethernet over VDSL port (symmetry

means upstream and downstream rate are the same or
similar) – the VDSL port can be RJ-11 connectors or BNC
connector. The VC-201/VC-202 can be set to CO mode or
CPE mode via a DIP switch. When the VC-20X-CO is used
to connect to the other VC-20X-CPE as a standalone pair, up
to 100/55Mbps asymmetric data rate within 200m and up
to 30/6Mbps asymmetric data rate at 1km. This capability
is ideal for use as an Ethernet extender for your existing
Ethernet network.
PLANET’s VDSL2 Converter solution provides
a
much
cheaper replacement and smooth migration for existing
Long Reach Ethernet (LRE) networks.
The cable specifications of the connection are listed as
following:
● 10BASE-T, Category 3, 4 or 5 UTP
● 100BASE-TX, Category 5 UTP
● Ethernet over VDSL, Twisted-pair telephone wires
● Ethernet over VDSL, Coaxial cable
The two drawings listed below are typical application for the
Ethernet over VDSL converter.
Slave device (CPE) must connect to Master
device (CO) through the telephone wire. Slave
cannot connect to Slave and Master cannot
connect to Master. To define the VC-201 to CO
or CPE, please refer to section 2.2.1 for more
detail.

2. Hardware Description
VC-201 provides 2 RJ-11 ports for voice connection (like
telephone or ISDN) and for network line connection.
VC-202 provides 1 BNC connector and supports 50 ohm
cable with distance of up to 1.6km
Both VC-201 and VC-202 provide 1 RJ-45 ports for two
different running speed –10Mbps, 100Mbps, in the same
converter and automatically distinguish the speed of
incoming connection.
This section describes the hardware features of these
Converters. For easier control of the converter, familiarize
yourself with its display indicators, and ports. Front panel
illustrations in this chapter display the unit LED indicators.
Before connecting any network device to the converter, read
this chapter carefully.

● Fast and Interleave mode: (For CO Mode only)
▪ Fast mode guarantees a minimum end to end latency
less than 1 ms.
▪ Interleaved mode provides impulse noises protection for
any impulse noise with a duration less than 250 us. In-

User has the ability to select fixed data rate. When Rate
Limit is selected, the system will lock the date rate at
50Mbps/20Mbps whenever the calculated SNR margin is
higher than 9 dB. This gives best system stability.
● Target SNR (Signal Noise Ratio) Margin: (For CO Mode only)
When fixed SNR margin is selected, the system will
maintain the SNR margin at 9 dB across all usable loop
length.
Please power off the converter before making any
transmission mode adjustment.
VC-201 and VC-202 require 5V DC power input. It will
conform to the bundled AC adapter. Should you have the
problem to make the power connection, please contact your
local sales representative.

3. Installing and Using VDSL Converter
3.1 Install the Ethernet Over VDSL2 Converter
The Converter does not require any software configuration.
Users can immediately use any feature of this product
simply by attached the cables and plug power on. There is
some key limitation on the Ethernet over VDSL2 converter.
Please check the following items:
● The device is used for Point-to-Point connection only
(Master device to Slave device) and allows data and voice
work on the same telephone or ISDN lines.
● VC-201 Two RJ-11 connectors for VDSL port. One for
voice device connection (like telephone) and the other
one for network link connection.
Depending on the quality of telephone line, the maximum
distance of one VDSL segment is 1.5km (5000ft) with
AWG 24 telephone wires.
● VC-202 1 BNC connector and supports 50 ohm cable.
Depending on the quality of coaxial cable, the maximum
distance of one VDSL segment is 1.6km with 5C coaxial
cable.
● The distance will change by the quality of telephone wires
and coaxial cables.
3.1.1 VC-201 LAN to LAN connection
Two sets of the converters could be used to link two local
Area networks that are located in different place. Through
the normal telephone line, it could setup a to 100/55Mbps

3.1.2 VC-201 Connect to Multi-Port Master
In order, to built up a local Internet in apartment, hotel,
campus and hospitality environment.
The Multi-port Master (for example, VC-810S VDSL2 Switch)
need to be placed In the wiring center (MDF room) and
connect to the telephone line system, on the other hand,
need to install a Slave (VC-201 CPE) converter on the
individual client side and connect to the Multi-port Master
through the telephone lines.
When deciding where to put the converter then you must
ensure:
● It is accessible and cables can be connected easily.
● Cabling is away from sources of electrical noise such as
radios, transmitters and power lines and fluorescent light-
ing fixtures.
● Water or moisture can not enter the unit Converter.

5. Troubleshooting
SYMPTOM:
VDSL LNK LED does not lit after wire is connected to the
VDSL port.
CHECKPOINT:
1.Verify the length of the wire connected between two VC-
201 is not more than 1.5km. Please also try to adjust the
DIP switch or VC-201 to other SNR mode.
2.Please note you must use one VC-201 with CO mode and
the other VC-201 with CPE mode, connect to each other
to make it work.
SYMPTOM:
TP LNK/ACT LED does not lit after cable is connected to the
port.
CHECKPOINT:
1.Verify you are using the Cat.5 or better cable with RJ-45
connector to connect to the port.
2.If your device (like LAN card) supports to Auto-Negotia-
tion, please try to manual set at a fixed speed of your
device to solve this problem.
3.The converter and the connected device’s power are on or
not.
4.The port’s cable is firmly seated in its connectors in the
switch and in the associated device.

6. FAQ
Q1: What voltage that VC-201/VC-202 used?
A1: 5VDC, 2A
Q2: What is VDSL2?
A2: VDSL2 (Very High-Bit-Rate Digital Subscriber Line 2),
G.993.2 is the newest and most advanced standard of
xDSL broadband wire line communications.
Designed to support the wide deployment of Triple Play
services such as voice, data, high definition television
(HDTV) and interactive gaming, VDSL2 enable opera-
tors and carrier to gradually, flexibly, and cost efficient-
ly upgrade exiting xDSL-infrastructure.
Q3: What is the best distance for VC-201?
A3: In order to guarantee the stability and better quality of
network, so we would suggest the distance in 1 kilome-
ter is the best for VC-201.
Q4: What is the best date rate for VC-201?
A4: We provide the data rate of the VC-201 is up to
55Mbps/100Mpbs (upstream / downstream) in 200 me-
ters.
Q5: Can VC-201 compatible with VC-102M / VC-102S?
A5: Our VC-201 is base on ITU-T G.993.2 VDSL2, and VC-
102M / VC-102S is VDSL1, so it can not compatible
with VC-201.
30
Download from Www.Somanuals.com. All Manuals Search And Download.
Q6: Can VC-201 compatible with VC-200M / VC-200S?
A6: Currently NO, although VC-201 and VC-200M/200S are
base on ITU-T G.993.2 VDSL2, but with different chip-
set specification, so far they are not compatible with
each other.
Q7: What is SNR and what’s the effect?
A7: In analog and digital communications, Signal-to-
Noise Ratio, often written SNR, is a measure of signal
strength relative to background noise. The ratio is usu-
ally measured in decibels (dB).
In digital communications, the SNR will probably cause
a reduction in data speed because of frequent errors
that require the source (transmitting) computer or ter-
minal to resend some packets of data. SNR measures
the quality of a transmission channel over a network
channel. The greater the ratio, the easier it is to iden-
tify and subsequently isolate and eliminate the source
of noise.
Generally speaking, the higher SNR value gets better
line quality, but lower performance.
