Adapter Configuration

In order to access the web-based configuration pages, it is necessary to know the adapter’s IP address and for your computer to be connected to the CableLAN adapter (as described in section 2.5). Corinex adapters come with a default IP address

10.10.1.69

.

Open a web browser (Microsoft Internet Explorer v6.0, Mozilla v1.7.2 and Mozilla

Firefox v1.0 have been verified for use with these products.), and type the IP address in the address bar – the URL should be

http://10.10.1.69/

unless you have already changed it to something else.

Changing the default IP address is required, so that two or more devices can be on the same network. The IP address is a device’s unique identifier on a network, so the adapters would not be able to tell each other apart if they had the same identity, just as a postman wouldn’t know which house to deliver to, if two neighbors in a large city had the same street number. Follow the steps below to configure a new

IP address for each adapter:

1. In your computer’s network settings, enter an address in the range 10.10.

X.X (e.g. 10.10.1.2) and set the netmask to 255.255.0.0. This is necessary in order to be compatible with the adapter’s default settings. For details on how

to set up an IP address on your computer, please see chapter 5.

3. Open your web browser and type

http://10.10.1.69

. You will then be able to

configure the settings for your CableLAN adapter.

3.4 Change Configuration Page

3.4.1 Overview

The configuration pages allow you to change the settings on the CableLAN adapter.

Any parameters changed here will be stored in the CableLAN adapter‘s permanent memory, and at the next startup, will be activated automatically. Any changes will take effect immediately after startup, with the exception of the Network Configuration settings (these require a restart of the CableLAN adapter).

The configuration is divided into two sections: “Basic settings” and “Advanced

settings.”

14

Notes :

• A different IP must be set for each adapter on the network. The adapter’s

IP does not need to be in the same range as the PC, except when trying to change the adapter’s settings on the configuration page (10.10.X.X and netmask

255.255.0.0 for an adapter with the default factory settings).

• The adapter’s netmask can also be changed, for example to a type C

(255.255.255.0) if necessary. This is a more advanced option, which you may ignore if you’re not familiar with it.

Corinex AV200 CableLAN Adapter

Adapter Configuration

• If the CableLAN adapter is to be accessed through a router (e.g., in a large office network), the gateway IP needs to be configured. Otherwise, it can be ignored.

WARNING: CHANGING AN ADAPTER‘S IP TAKES EFFECT ONLY

AFTER A RESTART. YOU MAY WANT TO PLACE A LABEL ON EACH

ADAPTER WITH ITS IP ADDRESS, SO YOU DON’T ACCIDENTALLY

LOSE THE ABILITY TO ACCESS IT.

Most of the time, the only thing that needs to be changed is the Network Identifier and the Encryption, in order to avoid interfering with other networks and protect your information. Most people will not need to enter the Advanced settings section.

The AV200 CableLAN network is totally secure with these basic settings.

15

The AV200 technology supports multiple networks on a single circuit. The networks are differentiated by Network Identifiers, which can be set in this section. The

Network Identifier is a string of characters (Network Identifier field) which simply acts as a name for the network. This Network ID must be identical for all adapters on a network. Adapters with different Network IDs will not be able to communicate with each other.

The Network Identifier string can have up to 20 ASCII characters (lettters and numbers). Quote and double-quote characters are not supported. Extended ASCII characters are not recommended.

Corinex AV200 CableLAN Adapter

Adapter Configuration

If you want to enable 3DES encryption in your network, please select one of the input methods and enter the password.

Input methods:

ASCII

HEX

If ASCII is selected, the Encryption Key string can have up to 24 non-extended

ASCII characters. Quote and doublequote characters are not supported.

Extended ASCII characters are not supported.

On the other hand, if HEX mode is selected, the Encryption Key string can have up to 42 hexadecimal digits (for example 34AE4F54B38D). This HEX method is more secure than ASCII.

3.4.3 Advanced Configuration

The advanced configuration section is divided into several subsections, which are described here.

3.4.3.1 MAC Configuration

The following parameters relate to the physical network setup, or topology. The current firmware version (Spirit 2.0.21 at the time of this publication) supports only one topology: In-Home AV. In this In-Home AV topology, two different adapter types can be configured, setting an adapter to function as either an Automatic

EP/AP (End Point or Access Point, depending on the other adapters in the network) or a Fixed AP (assigned Access Point). Section 4 (In-Home AV Network Topology) contains more information about the available network topologies.

16

Corinex AV200 CableLAN Adapter

Adapter Configuration

If you want to configure the CableLAN adapter to function as an automatic EP/AP, please select “EP” from the list. If you want the adapter to behave as a Master, select “Fixed AP” from the list. After selecting one, click “OK” to confirm your choice.

Note: Fixed AP is available only when a Network ID is set on the adapter

(please read below for details on Network Identifiers).

The AV200 technology supports multiple networks on a single circuit. The networks are differentiated by Network Identifiers, which can be set in this section. The

Network Identifier is a string of characters (Network Identifier field) which simply acts as a name for the network. This Network ID must be identical for all adapters on a network. Adapters with different Network IDs will not be able to communicate with each other.

Note: Please refer to section 4.2 for more information about the network types and their Network Identifiers.

If the Network Identifier field is left blank, the default, publicly available network is configured, and the adapter can communicate with all other adapters with empty

Network Identifier fields. When you enter a Network ID, a private network is configured.

Note: The Network Identifier string can have up to 20 ASCII characters.

Quote and double-quote characters are not supported. Extended ASCII characters are not recommended

17

Corinex AV200 CableLAN Adapter

Adapter Configuration

The following picture shows an example of two AV200 networks with different

Network Identifiers:

Communication between adapters (called modems in this picture) is encrypted with a Triple-DES algorithm. The Encryption Key can be set to any string of letters and numbers (Encryption Key field, ASCII or HEX). Saving an empty string (leaving it blank) disables the encryption. After selecting ASCII or HEX and then entering a password, click “OK” to confirm your choice.

Note: The encryption will be enabled only if a non-empty Network Identifier is set.

18

Note: If ASCII is selected, the Encryption Key string can have up to 24 non-standard ASCII characters. Quote and double-quote characters are not supported. Extended ASCII characters are not supported.

On the other hand, if HEX mode is selected, the Encryption Key string can have up to 42 hexadecimal digits (for example 34AE4F54B38D). HEX strings generate stronger keys.

Corinex AV200 CableLAN Adapter

Adapter Configuration

3.4.3.2 Network Configuration

Your Corinex AV200 CableLAN Adapter can be configured to use either DHCP

(automatic IP address assignment), or a fixed IP.

The following parameters are used by the fixed IP configuration. In order for the

CableLAN adapter to correctly communicate with other devices on the network, it is necessary to define a valid IP address, as well as a proper subnet mask and gateway address. These parameters will be saved in the CableLAN adapter’s memory and activated at the next restart.

After changing any of these parameters, click “OK” to save your changes.

Note: Any change in the Network Settings requires a restart of the CableLAN adapter to take effect.

Note: If you forget the IP address of the device, please recover it with the utility “getIP,” which is located on the Documentation CD, or download it from the Corinex website at www.corinex.com.

19

By default, the adapters transmit over a frequency range anywhere from 2 to 32

MHz, and when an access network is detected, the adapters transmit over a range from 13.3 to 33.3 MHz, in order to operate without interfering with each other.

This mode change is done automatically and cannot be configured by the user. It is only possible to enable or disable this „notches“ function. The notches pre-defined in the adapter correspond to the IARU (International Amateur Radio Union) band plan for each world region. If the adapter is running in an environment where it can cause interference to a HAM radio receiver, it is recommended to enable notches, in order to block the CableLAN signal from the frequency bands used by radio amateurs.

Corinex AV200 CableLAN Adapter

Adapter Configuration

Note: It is strongly advised to turn on the notching function.

Power Control is an automatic transmission power control which prevents different networks from overpowering each other.

Power Control is turned on only when other networks are detected in the channel.

If the transmission strength reaches the isolation point between networks, the transmission power is limited from overpowering the other network. If the isolation point is not reached, the adapters continue transmitting as normal.

In order to optimize multicast traffic (video streams, etc.) between AV200 CableLAN adapters, you can specify which adapters should receive the video. Other adapters will then not be able to receive the multicast communication, and therefore the bandwidth will be used only for transmission to the intended recipients, making your broadcast, and your entire network, more efficient.

This form shows the list of multicast bindings, where the IP addresses of adapters are assigned to a unicast (video source) MAC address. This list can be saved to memory on the CableLAN adapter (Save in NVRAM). Bindings can be removed by checking their “Remove” checkboxes and clicking “OK”. Add a new binding to the list by entering the multicast IP address in decimal format (ddd.ddd.ddd.ddd), and the unicast (source) MAC address, in hexadecimal format (XXXXXXXXXXXX), in the appropriate fields and clicking “OK.”

The new IGMP Aware Multicast Syndication feature can be enabled via this form.

This feature is only available on private networks (those with a valid Network

Identifier) and End Points (EP).

20

Corinex AV200 CableLAN Adapter

Adapter Configuration

When AV200 CableLAN Adapters are used for ADSL extension, it is important for the operator to be able to distinguish the type of traffic that each adapter is generating. This is usually done by means of VLAN tagging. The AV200 technology includes the ability to tag all traffic that enters the CableLAN network through each adapter’s Ethernet interface. It is only tagging - there is no VLAN filtering on an

AV200 CableLAN network.

The parameters for VLAN configuration can be set in the form displayed below.

First, the Spirit VLAN can be enabled or disabled (Spirit VLAN Configuration checkbox). If enabled, the VLAN tag (Spirit VLAN Tag field) and priority (Spirit

VLAN Priority field) can then also be configured.

It is possible to configure the Activity LED (in the middle of the front panel). The

LED shows the quality of the network connection to other AV200 devices. There are two configurable speed markers. The adapter simply reads the network speed and changes the blink rate of the Act LED according to these markers. The default values are 25 Mbps and 75 Mbps.

IMPORTANT NOTE: This advanced LED functionality is available only when a Fixed AP (described in section 3.4.3.1) is present on the CableLAN network.

In order to function correctly, the Fixed AP must be connected to your internet connection or to the first device on your network (i.e. modem or router). If there is no Fixed AP on the network, the LEDs may not behave as described below.

The behavior of the LED is described in the table below.

After setting both values, please click OK to save the values to NVRAM. The changes will be applied immediately and the LED behavior may change.

22

Corinex AV200 CableLAN Adapter

Adapter Configuration

Several options are available in this form. The first, and easiest to understand and use, is the Default Priority value. Output traffic generated by adapters with higher default priority will have preference in the network. The rest of the parameters let you configure two Class of Service criteria (Criterion 1 and Criterion 2 checkboxes).

If you select None, 8021p or TOS, custom parameters are hidden, leaving a predefined setting in place.

If you select Custom on the other hand, custom parameters are shown as below and can then be configured.

When several traffic flows are sharing the same network, it is sometimes necessary to establish several levels of priority in order to guarantee that bandwidth-sensitive applications like video and telephony function smoothly under network congestion.

The traffic classifier is a packet inspector that is able to recognize several patterns in an Ethernet frame, and assign a different priority to each of them. To ensure that the classification is done correctly, there is a trigger mechanism prior to the actual classification. The trigger mechanism is also based on pattern recognition of a given location in each Ethernet packet. The following picture depicts the packet classification mechanism:

23

There is one offset, and one bitmask and pattern for the trigger condition. The trigger condition is used to make sure that the Ethernet frame contains, for example, an IP frame. To check this condition, the offset must be set to 16 and the bitmask to 0xFFFF. If the resulting pattern is 0x0800, then the Ethernet frame contains an IP packet and the classification can be made to a known field.

There is another offset and bitmask for the classification condition. The resulting value is compared with a set of patterns. If the value matches a given pattern, the packet will be classified with the specified priority. If the value does not match any

Corinex AV200 CableLAN Adapter

Adapter Configuration

of the patterns, it will get a default priority.

There is a set of pre-defined criteria which classifies traffic based on the 802.1p field of the Ethernet packet or the TOS field of the IP packet.

The configuration page allows you to change the password. Type your new password and confirm by typing it in a second time. If both fields are left empty, the password will be disabled (the message ‘No password installed’ will be shown).

You can turn the password protection back on at any time by simply entering a password, as described above..

Factory reset will restore the adapter‘s default settings. The system will ask for the password, which is “betera“. Then click OK. The adapter will restart with the following configuration:

-

-

-

-

-

Configuration interface password = paterna

Factory reset password = betera

Device type is Automatic EP/AP

Network Identifier is blank

No encryption and no VLAN settings

3.4.9 Hardware Reset

Clicking on this button will restart your adapter. The configuration will remain the same, and any changes made in the Network Configuration section will be applied.

This means that if you’ve changed the IP address, the adapter will restart with the new IP address.

3.4.12 Configuring Video Applications

On a network where real-time traffic must co-exist with massive data transfers, the service classifier must be used to prioritize the more sensitive traffic above the other types of traffic.

As an example, consider the network shown below :

The adapter connected to the ADSL adapter is the access point. Data and video are delivered through ADSL. The access point must prioritize the video higher than other data, to avoid a jittery image whenever there is a heavy data download.

First of all, the Criterion field must be set to Custom, in order to create custom rules for traffic classification.

To prioritize UDP traffic, first the Ethernet packets containing IP packets must be detected. This requires detecting the pattern 0x0800 at offset 16. Because the field to inspect is two bytes, the bitmask must also cover the same space. Therefore,

0xFFFF is used as the bitmask. These values are introduced in the fields Custom

Criterion Offset, Custom Criterion Pattern and Custom Criterion Bitmask.

Once the trigger condition is entered, the classification rules must be specified.

Only the fields that are actually changed will take effect. The rest will be ignored.

IP packets have a one-byte field at offset 27 that indicates the Protocol Type.

UDP protocol is pattern 0x11. Because the field to inspect is only one byte, the bitmask is also one byte. The values are entered in the first available rule (1) as Class

Pattern 1 and Class Priority 1.

The rest of the traffic (FTP, web browsing, etc.) will receive default priority 2. On the other side of the network, the adapter connected to the computer will also classify outgoing data traffic with default priority 2 because no rule has been programmed.

Note: While the offset value is assumed to be decimal, the patterns and the bitmasks are in hexadecimal format by default.

3.5 Firmware Update Page

This page appears when a firmware update is requested from the Change

Configuration page, and it shows the status of the current firmware update.

The Firmware Update page is reloaded automatically every 30 seconds. When the status line shows Ready: finished correctly, the CableLAN adapter can be restarted, and the new firmware will be activated.

If the update process fails, an error message will be shown. In this situation, the

CableLAN adapter can be reset without any risk, but the old firmware will still be present on the adapter.

4.1 Introduction

An In-Home AV network is made up of an access point (AP) adapter and several end points (EPs). In-Home AV networks can have only one AP. However, several In-

Home AV networks can be created in the same space, each of them with its own AP, because each network is isolated by a unique network identifier. An adapter can be configured as a Fixed AP (i.e. it always will be an AP) or an automatic EP/AP. When set to automatic, the In-Home AV protocol decides which adapter will function as an AP. This means that if no Access Point (AP) has been defined, an End Point (EP) will be automatically set to function as an AP.

Note: It is recommended to configure a Fixed AP. This provides increased stability for future reconfigurations and in multi-network environments.

Note: It is not necessary to have full connectivity between all the adapters on a network. The network topology will be configured automatically, allowing for the use of repeaters if the connectivity between two adapters fails.

The necessary steps for setting up a basic In-Home AV network are, for each adapter, as follows:

on the network.

- It is not necessary to configure the In-Home AV MAC, since there is only one available network topology in the current firmware version. To configure a Fixed

AP is optional.

4.2 Network Scenarios

This section contains a few network scenarios, explaining the application and necessary configuration.

There are two types of In-Home AV network.

Corinex AV200 CableLAN Adapter

Video Network Setups

you do not want to change the settings on your network, the network configuration protocol will configure all the adapters automatically. By default,

all adapters are EPs and have a public (empty) network ID. If the protocol

does not detect an AP in the channel, it will change an EP to act as an AP. All

EPs will connect directly to the automatic AP if they can, or to an EP that will

act as a repeater. Then the network will be established.

a network ID must be assigned to all adapters on the network using the

configuration tool. It is recommended to configure a fixed AP (for example the adapter with the video server or Internet access). If the fixed AP is

turned off or is not defined, the network configuration protocol

will select an EP to change to function as an AP (automatic), in order to

configure the network.

4.2.1 Single-Network Scenarios

The following two sections show examples of a single In-Home AV network.

4.2.1.1 Local Area Network using two AV200 CableLAN Adapters

The picture below shows a simple CableLAN network where two adapters are used to make a local area connection available in all outlets of the house. This is the simplest case, where no QoS (Quality of Service) configuration is required.

Network

This picture shows a more advanced CableLAN network with three Corinex AV200

CableLAN Adapters. This is a common network configuration, where Internet access and digital video are delivered through the same ADSL line. This configuration requires some QoS (Quality of Service) settings to guarantee video quality when the network is carrying large amounts of data from the Internet connection.

Note: Either of these two basic scenarios can be enlarged, adding more adapters, computers and set-top-boxes.

4.2.2 Multi-Network Scenarios

A multi-network scenario occurs whenever there are two or more adapters from different networks (different network IDs) on the same circuit. In this case, a coexistence mechanism is included, which allows a secure form of communication without interference from adapters from other networks.

Corinex AV200 CableLAN Adapter

Video Network Setups

In multi-network scenarios, such as the one depicted in the picture above, there is a new entity, called the QoS controller. The QoS controller’s role is to assign channel access to the different networks. The QoS controller acts at the same time as the

AP of one of the networks. In the presence of several networks, the coexistence protocol automatically selects one of the APs as the QoS controller.

4.2.2.1 Two Networks on Different Circuits

If two In-Home AV networks are configured, with no direct visibility between any of the adapters belonging to different networks, then these two networks will behave as two independent networks. Both APs will act as QoS controllers.

4.2.2.2 Two Networks on the Same Circuit

Different networks are defined by different network IDs.

If two In-Home AV networks are configured as public networks, the coexistence protocol will act as if there were only one network. The network ID is transmitted by every adapter to communicate the existence of its network. If an adapter with network ID A receives network ID B, then it knows that there are at least two networks sharing the channel.

For example, one In-Home AV network is configured and running. A second network is configured and becomes active. Then the second network will notify the first network of its existence in some specified access slots, and both networks will automatically be reconfigured and will share the channel. If both networks are configured at the same time, the QoS controller will be selected from all available

APs.

5.2 Improving Network Performance

The latency (delay) of a CableLAN network is higher than that of an Ethernet network. Most operating systems have a default setting of the network latency based on Ethernet figures. To obtain the maximum performance using TCP traffic

(FTP download, for example) the operating system has to be tuned to the new network conditions.

For improving the network performance, we provide scripts for Windows and

Linux operating systems. The scripts can be found on the enclosed CD, in the folder

scripts. The scripts will set the TCP window size to 512 kB.

With a Windows PC, simply double-click on the file tcpwin.reg, provided on the documentation CD in the “scripts“ folder. You can also run the script using the autorun feature on the CD.

5.3 Checking Network Performance

On the Main page, under the heading Available CableLAN Connections, is a list of the MAC addresses of all of the neighboring adapters that have a connection with that adapter. The list also indicates the physical throughput (actual data rate), in terms of both transmission and reception, that the adapter is achieving with each adapter on the network.

5.4 Using Coaxial Filters

A coax filter is a high-pass filter which allows only the TV signal through. This filter blocks the AV200 CableLAN signal (2-34 MHz).

Corinex AV200 CableLAN Adapter

Network Configuration

When to use this filter:

• When you want to isolate your AV200 CableLAN network from the rest

of the coaxial infrastructure, either because you don’t want the CableLAN

signal from your network to go out and disrupt other adapters, or because

you want to isolate this network from the noise, or other traffic, in the rest of

the cable network.

Troubleshooting Guide

The Corinex AV200 CableLAN Adapter has been designed to be a reliable and easy-touse network connection device. Please refer to the list below to aid in troubleshooting or visit

www.corinex.com/retail

and go to the appropriate section for information on your product. There you will find news, manuals and software updates, as well as frequently asked questions (FAQ).

The POWER LED is off.

1. Make sure the CableLAN adapter is properly plugged directly into the electrical

outlet, and that the outlet has power.

2. Try another outlet.

The CableLAN Act LED is off.

1. Make sure there is no analogue TV amplifier or too many T-splitters between

the AV200 CableLAN adapters which should communicate.

2. Try to connect two AV200 CableLAN adapters with a short coaxial cable for

a short test to check the connectivity.

The Ethernet LED is off.

1. Make sure the adapter is connected with an Ethernet enabled device with an

RJ-45 cable and both devices are powered.

To avoid personal injury and damage to the system:

1. The principal method to disconnect the device completely from the electrical

power network (mains) is to unplug the power cord from the wall socket.

2. Never install the unit in wet areas or next to radiators/heaters.

3. Never use the unit outside.

4. Unplug the unit during severe storms.

5. Never open the equipment enclosure.

To verify that your equipment is connected and working correctly, use the standard

Ping utility. In Windows, click on menu Start -> Run, then type the command

ping IPADDRESS -t, where IPADDRESS is the IP address of the computer to which the CableLAN adapter is connected, e.g. ping 192.168.4.1 -t (this process can be interrupted by pressing CTRL+C).

1. Ping the IP address of the computer to which the CableLAN adapter

is connected. If this fails, there is a problem with the Ethernet

network card or with the TCP/IP protocol.

2. Repeat the same process with the other computers on your AV200 CableLAN

network.

41

Corinex AV200 CableLAN Adapter

Troubleshooting Guide

3. If all the computers can ping themselves, try pinging another computer on

your AV200 CableLAN network. If this fails, then there is a problem with the

connection across your AV200 CableLAN network or with the configuration

of the CableLAN adapters. Check the connection to the

outlet, or try a different outlet. Verify the configuration of your

adapters, especially the network number, as only adapters

on the same network can see each other. Please see chapter 3 for details on

configuration.

4. When a connection is made to another AV200 CableLAN device, the Act

LED (in the middle) will be on or blinking, depending on the connection

speed. This is explained in more detail under QoS Settings in section 3.4.7.
