1.2 Introduction to Ethernet over VDSL2 Bridge
Data Connect'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 2). This
technology offers the absolute fastest possible data transmission
speeds over existing copper telephone lines without the need for
rewiring.
The 2178HSEE & HSEE4 Ethernet over VDSL2 Converter / Bridge
has switching architecture with 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 beRJ-11connectors. The 2178HSEE & HSEE4 can
be set to CO mode or CPE mode via a DIP switch, when the
2178HSEE / HSEE4-COisusedto connecttotheother 2178HSEE /
HSEE4 CPE as a standalone pair, up to 100/100Mbps symmetric
data rate within 300m and up to 50/2Mbps asymmetric data

rate at 1.4km. This capability is ideal for use as an Ethernet
extender for your existing Ethernet network.
Data Connect'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
The two drawings listed below are typical application for the
Ethernet over VDSL2 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 the2178HSEE / HSEE4 to CO or
CPE, please refer to section 2.2.1 for more detail.

2. Hardware Description
The 2178HSEE provides 1 RJ-11 port for VDSL2 connection, for
both VDSL2 connection and voice connection service operate at
the same time. The additionalsplitterfrompackageof 2178HSEE
can help 2178HSEE work in this way easily.
The2178HSEE4 provides 2 RJ-11 ports for voice connection (like
telephone) and for network line connection.
The2178HSEE provide 1RJ-45 portand2178 HSEE4 provide 4RJ-45
ports for two different running speed –10Mbps, 100Mbps, in the
same converter / bridge and automatically distinguish the speed
of incoming connection.
This section describes the hardware features of the Ethernet
over VDSL2 Converter / Bridge. For easier control of the
converter / Bridge, 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 / Bridge, read this chapter carefully.

2.2.1 MODE DIP Switch
The Ethernet over VDSL2 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 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 Prole SNR
OFF CO Interleave 17A 9dB
ON (default) CPE Fast 30A 6dB

17
nDIP-1: Mode (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 receiver. The CPE
can be connecting to the PC, IP Camera or Wireless Access
Point or other network devices.
Note
When the Ethernet Over VDSL2 Converter oper-
ates at CPE mode, the DIP switch 2, 3, 4 is no
function.
nDIP-2: Channel (Fast and Interleave mode)
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. Interleaved
mode has a maximum end to end latency of 10m sec.
n DIP-3: Prole (17A/30A)
User has the ability to select prole. When 30a is selected
that provides better downstream/upstream performance in
short distance, when 17a is selected that provides longer
distance link capability. Refer to section 1.4 specication for
details.
nDIP-4: SNR (9dB/6dB) Target SNR (Signal Noise Ratio)
Margin
When SNR margin is selected, the system provide 9dB/6dB
SNR margin for across all usable loop length.

Note
1. By default, the four DIP switch are at “ON”
position that will operate as “CPE”. For operate
as “CO”, please adjust the DIP 1 switch at
“OFF” position. Then adjust other DIP switch
accordingly to fulfill different network applica-
tion demand.
2. Please power off the Ethernet over VDSL2
Converter, before making any transmission
mode adjustment.
2.2.2 DC power jack
2178HSEE / 2178HSEE4 require 5V DC 2A power input. It will
conform to the bundled AC adapter. Should you have the
issue 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 Ethernet
Over VDSL2 Converter / Bridge from being
damaged by unregulated surge or current to
the Ethernet Over VDSL2 Converter / Bridge or
the power adapter.

3. Installing and Using VDSL Converter
3.1 Install the Ethernet Over VDSL2 Converter
The Ethernet over VDSL2 Converter / Bridge 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 / Bridge. 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 lines.
2178HSEE provides one RJ-11 connector for VDSL port and
the port can build VDSL2 connection easily. For voice device
connection, the additional splitter from 2178HSEE package is
an idea choice.
2178 HSEE4 provides two RJ-11connectors 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 1.4km (4593ft) with AWG
24 telephone wires. The distance could vary by the quality of
telephone wires or the installed environment.

3.1.1 2178HSEE / 2178HSEE4 LAN to LAN connection
Two sets of the Ethernet over VDSL2 Converters / Bridge
could be used to link two local Area networks that are located
in different place. Through the normal telephone line, it could
setup a 100/100Mbps symmetric backbone, but one Ethernet
over VDSL2 Converters / Bridge must be Master (CO mode) and
the other one is Slave (CPE mode).
