Chapter 1: Introduction

Introduction

GE Security'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 coaxial cables without the need for rewiring.

The MCE-Coax Ethernet over VDSL2 converters have a switching architecture with one RJ-45 10/100Mbps Ethernet port and one asymmetric Ethernet over VDSL port. The VDSL port uses a BNC connector. The MCE-Coax can be set to CO mode or CPE mode via a DIP switch. When the MCE-Coax-CO is used to connect to the other MCE-Coax-CPE as a standalone pair, you can get up to a 100/65Mbps asymmetric data rate within 200m and up to

70/10Mbps asymmetric data rate at 1.6km. This capability is ideal for use as an Ethernet extender for your existing Ethernet network.

GE Security's VDSL2 Converter solution provides a much cheaper replacement and smoother 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, 6 UTP

• Ethernet over VDSL, Coaxial cable

Figure 1 shows a 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 MCE-Coax to CO or CPE, please refer to the Mode DIP

Switch section for more detail.

Hardware Overview

MCE-Coax provides 1 BNC connector and supports 75-ohm cable with a distance of up to 1.6km. It has 1 RJ-45 port for two different running speeds -

10Mbps, 100Mbps, in the same converter and automatically distinguishes 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.

Front Panel

The MCE-Coax front panel provides a simple interface monitoring the converter.

Chapter 2: Hardware Overview

CPE (customer premises equipment) - the Slave device mode, usually the CPE device will be located at a branch office, home or remote side as a long reach data receiver. The CPE can be connected to the PC, IP

Camera or Wireless Access Point and various network devices.

Fast and Interleave mode: (For CO Mode only)

• Fast mode guarantees a minimum end to end latency of 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.

Rate Limit: (For CO Mode only)

User has the ability to select fixed data rate. When a Rate Limit is selected, the system will lock the data rate at 50Mbps/20Mbps whenever the calculated SNR margin is higher than 9 dB. This gives the best system stability.

Target SNR (Signal Noise Ratio) Margin: (For CO Mode only)

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

Power Information

Remove power from the converter before making any transmission mode adjustments.

MCE-Coax requires 5V DC power input.

NOTE:

The device is a power-required device, which means that it will not work untill it is powered. If your networks are active all the time, please consider using UPS (Uninterrupted Power Supply) for your device. It will prevent network data loss or network downtime.

In some areas, 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.

Installtion

Installing Ethernet with the VDSL2

Converter

The Converter does not require any software configuration. Users can immediately use any feature of this product simply by attaching the cables and plugging the power in. There are certain key limitations on the Ethernet over VDSL2 converter. Please check the following items:

• This device is used for Point-to-Point connection only (Master device to

Slave device).

• 1 BNC connector and supports 75 ohm cable. Depending on the quality of coaxial cable, the maximum distance of one VDSL segment is 1.6km with 5C coaxial cable.

• The maximum distance will change with the quality of coaxial cables.

FAQs

Troubleshooting

SYMPTOM:

The VDSL LNK LED is not lit after the wire is connected to the VDSL port.

CHECKPOINT:

1. Verify the length of the coaxial cable connected. The cable length between two MCE-Coaxs should not exceed 1.6km. Also try to adjust the

DIP switch of MCE-Coax to another SNR mode.

2. Please note one MCE-Coax must be in CO mode and the other MCE-Coax must be in CPE mode for communication to work.

MCE-Coax Converter User Manual 19

Chapter 4: Troubleshooting and FAQs

SYMPTOM:

The TP LNK/ACT LED does not lite after the cable is connected to the port.

CHECKPOINT:

1. Verify you are using the Cat.5 or better cable with an RJ-45 connector to connect to the port.

2. If your device (like LAN card) supports Auto-Negotiation, please try to manually set at a fixed speed for your device to solve this problem.

3. The converter and the connected device's power is not on.

4. Make sure that all the cabling is firmly seated in its connectors in the switch and in the associated device to which the port's cable is attached.

5. The connecting cable is correctly working and is the correct type.

6. The connecting device, including any network adapter, is functional.

FAQs

Q1: What voltage does the MCE-Coax use?

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 operators and carrier to gradually, flexibly, and cost efficiently upgrade exiting xDSL-infrastructure.

Chapter 4: Troubleshooting and FAQs

Q3: What is the best distance for MCE-Coax?

A3: In order to guarantee stability and a better network, we suggest that the distance of 1.6 kilometer is the maximum distance for the MCE-Coax.

Q4: What is the best date rate for the MCE-Coax?

A4: The data rate of the MCE-Coas is up to 65Mbps/100Mpbs (upstream / downstream) in 200 meters.

Q7: What is SNR and what's its 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 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 the better the line quality, but lower performance.
