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

8
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 specications 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.
Note
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.
2.1 Front Panel

2.2 The Rear Panel
The rear panel of the converter is shown below.
● VC-201 / VC-202 Rear Panel
2.2.1 MODE DIP Switch
The converter provides 4 selective transmission modes.
By switching the transmission modes, you can obtain a
best transmission mode to suit with phone line quality or

17
distance of connectivity. The following is the summary table
of transmission setting, bandwidth and distance extensibility
tested for AWG 24 (0.5mm) twisted-pair without noise and
cross talk.
DIP-1 DIP-2 DIP-3 DIP-4
Mode Channel Rate Limit SNR
OFF CO Interleave 50/20 Mbps 9dB
ON(default) CPE Fast No Limit 6dB
● CO / CPE
▪ CO (Central Ofce) – the Master device mode, usually
the CO device will be located at the data center of ISP
or enterprise to link to the backbone.
▪ CPE (customer premises equipment) – the Slave device
mode, usually the CPE device will be located at branch
ofce, home or remote side as the long reach data re-
ceiver. The CPE can be connect to the PC, IP Camera or
Wireless Access Point and etc network devices.
● 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-
terleaved mode has a maximum end to end latency of
10m sec.

18
● Rate Limit: (For CO Mode only)
User has the ability to select xed 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 xed 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.
Note
1.The device is a power-required device,
it means, it will not work till it is
powered. If your networks should active
all the time, please consider using UPS
(Uninterrupted Power Supply) for your
device. It will prevent you from network
data loss or network downtime.
2.In some area, installing a surge
suppression device may also help to
protect your converter from being
damaged by unregulated surge or
current to the converter or the power
adapter.

3. Installing and Using VDSL Converter
3.1 Install the Ethernet Over VDSL2 Converter
The Converter does not require any software conguration.
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

20
asymmetric backbone, but one converter must be Master
(CO mode) and the other one is Slave (CPE mode).
Figure 3-1: VC-201 LAN to LAN connection
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 uorescent light-
ing xtures.
● Water or moisture can not enter the unit Converter.
