OVERVIEW

MEG201AE works as a transparent point to point Bridge for Ethernet and/or Telephony

connections using a Transmitter and a Receiver. When used with the VDSL2 switch

MEG821AE it is a Multipoint to Point solution. The MEG201AE uses new VDSL2

technology operating at different frequency bands with the feature to adapt its

performance to the characteristics of the copper medium used. The following cable

lengths and bandwidths are possible according to the band profile setup:

30a (Default band profile) 0-350m at 100Mbps down- and upstream

350-450m at 70-85/40Mbps downstream/upstream

450-600m at 40-60/10Mbps downstream/upstream

600-900m at 20-40/1-5Mbps downstream/upstream

Using Band profile 30a for distances

beyond 900m is not recommended

8d (Alternative band profile) 0-800m at 60-80/15 Mbps downstream/upstream

800-1200m at 30-50/5-10 Mbps downstream/upstream

1200-1500m at 30/2-5 Mbps downstream/upstream

Using Band profile 8a for distances

beyond 1500m is not recommended

Downstream: Traffic from Transmitter to Receiver

Upstream: Traffic from Receiver to Transmitter

For distances higher than those mentioned above, the MEG201AE is not the

recommended product. Other Black Box xDSL products should then be your

choice. Check MDS93x, MDS95x, MDE5xxx or MEG101 series products to get

distances of many many kilometers

These distances may and will vary depending on the quality of your wires. Keep in mind

that every intermediate connection of the cable will possibly increase losses and result in

less reach and/or bandwidth. Avoid cables that are not truly isolated, that may get wet or

are old and corroded. Running high power current nearby is also not recommended due

to the possibility of induced interference.

Avoid using telephony RJ11 ribbon cables. These cables are built with using very

low diameter stranded cables. Using them will mean that bandwidth is lower and

reach is shorter!

The front-panel provides LED indication of system and interface status. The in-built

POTS splitter allows a standard POTS phone to be connected at the Receiver. Full or

half duplex mode LAN operation is automatically sensed and configured. The

MEG201AE features an integrated 4 Port 10/100 Switch. Because of the switch please

consider that some non standard Ethernet Frames will not pass MEG201AE.

MEG201AE is configured by Web management. The serial port is intended to be used

by support staff with technical skills only. The standard IP addresses of the MEG201AE

set up are:

Transmitter MEG201TAE 192.168.16.249

Receiver MEG201RAE 192.168.16.250

Use the Webbrowser of your choice (older versions of Netscape or IE may not be able to

show you all options) to address MEG201AE. The default password is admin

INSTALLATION

For most applications you just need to connect the Transmitter and Receiver and power

them up (Picture shows Transmitter on the Left, Receiver on the Right)

Since the Receiver and Transmitter have their own IP addresses please check that the

addresses 192.168.16.249 and 192.168.16.250 are not in use by any other of your

network equipment. Initially, it may be useful for you to just connect Transmitter and

Receiver to the VDSL Line without connecting any other network equipment.

When using the VDSL2 switch (MEG821AE) please do not forget that all Receivers have

the same default IP address. It is recommended to change the IP address of each

receiver on its own before connecting to the switch.

For wire lengths within the distance limits previously mentioned (<900m), the system will

automatically establish the Link and set itself up. The MEG201AE is built using a

switching chipset and so some special Ethernet Frames will not pass across the VDSL

Link. Standard TCP und UDP traffic will pass to the other side transparently. The

MEG201AE is optimised for TCP traffic. If you use UDP traffic for Video Transmission

with high Frame sizes you will experience non optimal results.

After the Link between the Transmitter and Receiver has been established successfully

the WAN/LINK LED will be in a steady on state. At this point you should set up

appropriate IP addresses for the Transmitter and Receiver. You do this by either using a

PC within the subnet of the default IP addresses (192.168.16.x) or by setting a

temporary IP address by RS232 connection. See the next chapters for more information.

_____________________________________________________________________________

CONFIGURING BY WEB

The MEG201AE can be configured by using a Web browser. The modems have default

IP addresses and to use the Web Configuration method you need a PC within the same

subnet as the default IP addresses of MEG201AE.

MEG201AE Transmitter 192.168.16.249

MEG201AE Receiver 192.168.16.250

You can for example set your PC up with IP address 192.168.16.1. Please consult the

manual of your operating system on how to do this. If you can not change the IP address

of your PC then choose the alternative method to configure the IP address of

MEG201AE by RS232 serial (see below).

By entering the IP address as the URL into your browser you can get access. A window

will appear asking you for login. The default password is admin.

(Transmitter on Left, Receiver on Right)

The Screen you will see looks very similar for both the Transmitter and Receiver. Click

on Advanced Setup to configure the modem. The next screen will show you:

As you can see the Receiver offers you more options to configure. This is because you

can use the Receiver as an ADSL2+ Modem to be used with your incoming Internet

Service Provider Line as well as a point to point solution. Since the purpose of this

manual is to describe setup for your VDSL2 link please leave the options for

WAN/NAT/Firewall/Route and uPnP unchanged!

VDSL2

Channel Config

Lets you control the bandwidth passing across the Link.

(Factory Default is 64 kbps Minimum and 102400 kbps Maximum)

Also gives you the chance to set up Interleave. Higher Interleave values may give you a

more consistent latency.

(Factory Default is 1ms)

Line Config

Lets you configure the target SNR value for your Link that is acceptable. By lowering

that value you may get a link at a higher reach, but it will not be stable.

(Factory Default is 6 db)

Profile Config

Lets you configure the profile being used for your Link.

You can choose Profile, Band Plan, Filter and Tone Mode for the Transmitter.

You can choose Filter and Tone Mode for the Receiver.

Filter and Tone Mode of Transmitter and Receiver need to match.

(Factory Default for Filter is Off, for Tone Mode is V43)

The choosen Profile and Band Plan of the Transmitter are automatically

detected by the Receiver

The Profile and Band Plan tell the Modems which frequencies are being used and how

data is processed and transferred. The Filter and Tone Mode tells the modem

specialities about the line.

Optimal Setups:

Profile 30a, Annex C_8K, Filter Off and Tone Mode V43 for High Bandwidth

Profile 8d, Annex A M1_EU32, Filter Off and Tone Mode B43 for Long Distance

Bands Config

Let you configure special frequencies to be used.

Do not make any changes unless specifically advised by Black Box!

CONFIGURING BY RS232

MEG201AE features a Serial RS232 Port. Use a straight through (1:1) cable to configure

the MEG201AE using Hyperterminal or any VT100 application of your choice.

You need to setup a bitrate of 115200bps with 8N1 without any handshaking.

If the MEG201AE has been powered up already you will see a prompt by hitting the

ENTER key:

/ #

If you have not powered up MEG201AE, please do so and wait until the boot process is

finished. The boot process finishes with the following (for the Transmitter, the Receiver

looks very similar):

As you may identify from the commands above MEG201AE is a Linux based device.

Many of the common Linux commands can be used here. However, please consider that

you purchased a VDSL2 modem device, not a PC. And always keep in mind that Black

Box gives you support for configuring a standard VDSL2 modem. If you try to use the

MEG201AE as a Linux hardware platform and modify its internal software structure

there is no support or warranty on the unit.

_____________________________________________________________________________

You can use the Serial Interface to configure an IP address by this command:

ifconfig adm0 <ipadress> netmask <subnetmask>

(Example: ifconfig adm0 192.168.16.240 netmask 255.255.255.0)

This configuration is activated immediately but is only temporary because not stored in

flash memory. We recommend you continue configuring by Web method.

Other commands very useful:

rawaccess –e (Factory Default)

reboot (RESET)

ping (check connectivity to an IP address)
