Ethernet over VDSL2 Bridge Description

IFS’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 or
coaxial cables without the need for rewiring.

The IFS MC250-4T/1CXT Industrial Ethernet Converter has a
switching architecture with 4 RJ-45 10/100Mbps Ethernet ports
and one asymmetric or symmetric Ethernet over VDSL port
(Asymmetric means upstream and downstream rate are not
the same and Symmetric means upstream and downstream
rate are similar) – the VDSL port can be RJ-11or BNC
Connector.

The MC250-4T/1CXT can be set to Master or Slave mode via
a DIP switch. The MC250-4T/1CXT coax symmetric data rate
performance will be 95/99Mbps for at 200m, and 19/13Mbps at

IFS MC250-4T/1CXT User Manual 1

2400m. The MC250-4T/1CXT (BNC) coax performance is up
to 100/65Mbps for asymmetric data rate within 200m and
31/4Mbps for asymmetric data rate at 2.4km.

The IFS MC250-4T/1CXT Industrial Ethernet Converter is
engineered in a slim metal enclosure that conforms to IP30
standards for deployment in demanding industrial
environments.

The IFS MC250-4T/1CXT provides a lower cost 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, 5e or 6 UTP

• Ethernet over VDSL2, Twisted-pair Telephone Wires

• Ethernet over VDSL2 Coaxial Cable

Note: Slave devices (CPE) must connect to the Master device

(CO) through the telephone wire or coaxial cable. To define
the MC250-4T/1CXT as a Master or Slave, please refer to the
Mode DIP Switch section for more detail.

Hardware Overview

The MC250-4T/1CXT provides 4 10/100 Mbps RJ-45, 1 RJ-11
and 1 BNC port for network line connection. The 4 RJ-45 ports
will distinguish the speed of incoming connection
automatically.

This section describes the hardware features of the MC250­4T/1CXT. For easier control of the MC250-4T/1CXT, it's

recommended to get familiar with the LED indicators and port
characteristics. Front panel illustrations in this chapter display

the units LED indicators. Before connecting any network
device to the MC250-4T/1CXT, read this chapter carefully.

Master / Slave

• Master (Central Office) – in Master device mode, usually
the Master device will be located at the data center of the
ISP or enterprise to link to the backbone. For IP video

applications, the Master (CO) setting should be used at the
IP camera for maximum bandwidth availability over
distance.

• Slave (Customer Premises Equipment) – the Slave device
mode, usually the Slave device will be located at branch
office, home or remote side as the long reach data
receiver. The Slave also can be connected to the network
devices such as a PC, VoIP, Wireless Access Point, etc.

When the MC250-4T/1CXT is operating in Slave mode, the
DIP switch 2, 3, and 4 are disabled.

Fast and Interleave mode

• Fast mode guarantees a minimum end to end latency of
less than 1 ms.

6 IFS MC250-4T/1CXT User Manual

• Interleaved mode provides impulse noises protection with a
duration of less than 250 µs. Interleaved mode has a
maximum end to end latency of 10m sec.

Band Plan

• User can switch the Band Plan to either Symmetric or
Asymmetric based on the application. Symmetric band plan

provides better upstream performance while Asymmetric
band plan provides a better downstream performance.

Target SNR (Signal Noise Ratio) Margin

• When fixed SNR margin is selected, the system will
maintain the SNR margin at 9 dB across all usable loop
length.

Note: The default for the DIP switch settings is "ON" for all

four switches, that sets the media converter to CPE mode. For
selecting "CO" mode, please adjust the DIP 1 switch to "OFF".

Please power off the MC250-4T/1CXT before making any
transmission mode adjustments.

The Top Panel

The top panel of the MC250-4T/1CXT consists of a terminal

Installation

Installing the MC250-4T/1CXT

The MC250-4T/1CXT does not require any software
configuration. Users can immediately use any feature of this
product simply by attaching the cables and power plug. There
is some key limitation on the MC250-4T/1CXT. Please check
the following items:

MC250-4T/1CXT: The device is used for Point-to-Point
connection only (Master device to Slave device) and is
equipped with one RJ-11 and one BNC connectors for VDSL2
port for network link connection.

Phone wire: Depending on the quality of the telephone line
being used, the maximum distance of one VDSL segment is

1.6km (5249ft) with AWG 24 telephone wires.

Coaxial: Depending on the quality of the coaxial cable being
used, the maximum distance of one VDSL segment is 3.0km
(9842ft) with 50 or 75 ohm coaxial cable.

The distance achieved will vary according to the quality of
telephone wires and coaxial cables.

MC250-4T/1CXT Application Connection

Two sets of the MC250-4T/1CXTs could be used to link two
local Area networks that are located in different locations.
Through a normal telephone line or coaxial cable, 100/55Mbps
(RJ-11) or 100/65Mbps (BNC) asymmetric backbone, can be
setup with one media converter in Master (CO) mode and the
other in Slave (CPE) mode.

Troubleshooting

SYMPTOM:

VDSL LNK LED does not light after wire is connected to the
VDSL port.

CHECKPOINT:

• Verify that the length of the wire connected between two
MC250-4T/1CXT is not more than 2.4km. Please also try to
adjust the DIP switch of MC250-4T/1CXT to other SNR
mode.

• Please note you must use one MC250-4T/1CXT with
Master mode and the other MC250-4T/1CXT with Slave
mode.

SYMPTOM:

TP LED does not illuminate after the cable is connected to the
port.

CHECKPOINT:

• Verify that you are using the Cat.5, 5e or 6 cables with RJ­45 connector to connect to the port.

• If your device (i.e. LAN card) supports Auto-Negotiation, try
to set it to a fixed speed manually.

• Make sure that both converter and the connected devices
are turned on.

• Make sure that all cables are properly plugged in to the
correct ports.

• Make sure that the cable is not bad.

• Make sure that the power adapters are functional for each
device.

FAQs

Q1: What is the voltage and current rating to power MC250-

4T/1CXT media converter?

A1: 12 ~ 48V DC

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 operators and carrier to
gradually, flexibly, and cost efficiently upgrade exiting xDSL­infrastructure.

Q3: What distances can be achieved between MC250-4T/1CXT
media converters?

A3: Under ideal conditions and use of quality cable maximum
distances of 1.4 km for telephone wire (POTS) or 2.4km for
coax cable can be achieved.

Q4: What is the maximum date rate for MC250-4T/1CXT?

A4: Under ideal conditions and use of quality cable maximum

distances: 200 meters, 99Mbps/63Mbps
(downstream/upstream) for telephone cable or
100Mbps/65Mbps (downstream/upstream) for coax cable.

Q5: What is SNR and what’s the effect?

A5: In analog and digital communications, Signal-to-Noise

Ratio, often written SNR, is a measure of signal strength

16 IFS MC250-4T/1CXT User Manual

relative to background noise. The ratio is usually 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 terminal 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 identify and subsequently isolate and eliminate
the source of noise.

Generally speaking, the higher SNR value gets better line
quality, but lower performance.

Q6: What is band plan and what’s the effect?

A6: VDSL2 defines multiple band plans and configuration

modes (profiles) to allow asymmetric and symmetric services
in the same binder (by designated frequency bands) for the
transmission of upstream and downstream signals. User has
the ability to select fixed band plan. Symmetric band plan

provides better downstream performance while Asymmetric
band plan provides better upstream performance.
