1.3 How to understand the COVERAGE LED colors
The COVERAGE LED displays quality of the network and provides important information that will provide
solutions to common questions, such as why a High Definition (HD) movie is not showing or shows with
pixels. The COVERAGE LED indicator will vary its color depending on the estimated speed of the
Powerline connection. The speed is measured in Megabits Per Second (Mbps).
Color
Information
RED
The current connection has standard quality, normal Internet
activities ex. 20Mbps are possible but the Powerline is unable to
transmit either a Standard Movie or High Definition (HD) Movie.
ORANGE
The current connection has good quality and Internet activities
ex. greater than 20Mbps and less than 40Mbps to transmit
Standard Movie and HD Movie.
GREEN
The current connection has excellent quality and Internet
activities ex. greater than 40Mbps to transmit multiple Standard
Movies and HD Movies.

1.4 Point-to-Point Network
CASE 1: Estimated throughput is less than 20 Mbps. The PLC channel is not able to transmit an SDTV
channel. The COVERAGE LED will be RED as shown in the following figure:
CASE 2: Estimated throughput is greater than 20 Mbps but less than 40 Mbps. The PLC channel is
able to transmit an SDTV channel, but not two SDTV channels simultaneously or one HDTV channel.
The COVERAGE LED will be ORANGE as shown in the following figure:
CASE 3: Estimated throughput is greater than 10 Mbps. The PLC channel is able to play at least two
SDTV channels or 1 HDTV. The COVERAGE LED will be GREEN as shown here:

1.5 Point to Multipoint Network
In the case where the PLC network is composed of three or more adapters, similar situations could arise as
with a point-to-point network.
CASE 1: The COVERAGE LED in G.hn adapter 2 and G.hn adapter 3 will show the estimated level of the
PLC link receiving from G.hn adapter 1.
CASE 2: The COVERAGE LED in G.hn adapter 1 will show the estimated level of the PLC link from which
it is receiving the most amount of traffic at any given time. For example, if G.hn adapter 1 is receiving
traffic at 50Mbps from G.hn adapter 2 and is receiving 25Mbps from G.hn adapter 3, the COVERAGE
LED will show the level with reference to the G.hn adapter 2 link, as shown in the following figure.

Chapter 2 Log In Procedure
2.1 Configure STATIC IP MODE
In static IP mode, you assign IP settings to your PC manually.
Follow these steps to configure your PC IP address to use subnet 10.10.1.x.
NOTE: The following procedure assumes you are running Windows XP. However, the general steps
involved are similar for most operating systems (OS). Check your OS support documentation for
further details.
STEP 1: From the Network Connections window, open Local Area Connection (You may also access this
screen by double-clicking the Local Area Connection icon on your taskbar). Click the Properties
button.
STEP 2: Select Internet Protocol (TCP/IP) and click the Properties button.
STEP 3: Change the IP address to the domain of 10.10.1.x (69<x<255) with subnet mask of
255.255.255.0. The screen should now display as below.
STEP 4: Click OK to submit these settings.

2.2 Logging In
Perform the following steps to login to the web user interface.
STEP 1: Start the Internet browser and enter the default IP address for the device in the Web address field.
For example, if the default IP address is 10.10.1.69, type http://10.10.1.69
STEP 2: A dialog box will appear, such as the one below. Input the default Authentication Password.
Authentication Password: paterna
Click OK to continue.
Note:
The Factory Reset password is: betera

Chapter 3 G.hn Interface
3.1 Basic Configuration
Domain Name string of all nodes in the network.
Force node Type force the modem to have a particular role (END POINT or DOMAIN MASTER)
G.hn profile of all nodes in the network: selecting which G.hn profile must be applied to the network
(PLC 50MHz, PLC 50MHz with MIMO, PLC 100MHz, COAX 100MHz and PHONE 100MHz).

3.2 NDIM Configuration
NDIM mode set to Automatic for enabling automatic DOD selection functionality and set to Manual
for manual configuration of DOD.
Domain ID (DOD) manually set the DOD number from 1 to 15 to use a different preamble seed
than the default 0.
3.3 Encryption Configuration via WEB UI
Pairing Password used for authentication. Write a custom password to manually create a secure
domain.
Available Connections
In this tab table, all the available G.hn connections are presented. Remote node DID and MAC
address, transmission and reception physical speeds.

Chapter 4 IP Interface
4.1 IP config
In the IP configuration tab of one G.hn node, the IPv4 and IPv6 settings can be read and changed.
IPv4 subsection:
DHCPv4 enabled: in the case of choosing "No" (i.e fixed) IP configuration in the previous option, the
IPv4 Address, Subnet Mask, Default Gateway and DNS IPv4 Address should be configured; fill these
fields in. In the case of choosing “Yes” (i.e DHCP) they will be filled automatically when configuration
is received from the DHCP server.
IPv6 subsection:
DCHPv6 enabled: to enable the IPv6 DHCP configuration or choose not to.
DHCPv6 Address: to read the node's DHCPv6 address in case the DHCPv6 is enabled.
IPv6 Link Local Address: to read the node's Link Local address.
Manual IPv6 Manual Address: to configure up to four IPv6 Manual Addresses for the node.
DNSv6 Address: to configure the DNS address.

Chapter 5 Ethernet Interface
The Ethernet table shows the coverage & Info of the Ethernet interface; including Interface, Speed, Duplex,
Interface Type, Mode, Internal PHY & Link.
Powersaving
Ethernet powersaving can be disabled, enabled by Ethernet link or enabled by Ethernet activity; idle timer
can be configured as well.

Chapter 6 Device Interface
6.1 HW information
In this tab, basic information such as MAC Address, Serial Number, HW Product and Revision, ASIC and
Chipset of the selected node is shown. Other information about the Ethernet port is also shown.

6.2 SW information
Shows the FW version and system uptime.
Configuration password
The nodes in the network: to change the configuration password string from the default ("paterna") to
another; decided by the user.
Software update:
Current loaded firmware and API version are shown. SW can be upgraded via FTP or TFTP. L2 is proprietary
and is reserved for future use. Additionally, HTTP protocol can be also used for SW upgrade. Usually, a
reboot should be performed afterwards to make sure the changes are effective.

Chapter 7 Multicast Interface
7.1 MCAST Configuration
In the MCAST Configuration tab of "My Network", IGMP snooping and MLD features can be enabled or
disabled. Also, IGMP multicast IP addresses ranges which the G.hn PLC network will sniff; can be configured.
IGMP Snooping: Enable or Disable.
MLD Snooping: Enable or Disable.
IGMP/MLD broadcast report (allowed): set to NO for enabling reports dropping until the video
source is detected, this is a recommended setting when IGMP/MLD is enabled. Set to YES for
broadcasting reports until the video source is detected; this implies the multicast video stream is
sent as broadcast and it is the recommended state when IGMP/MLD is disabled.
IGMP Multicast ranges configuration: 4 multicast IP address ranges can be configured defining the
minimum and maximum IP addresses of each range. Only multicast traffic within these ranges will be
processed.

Chapter 8 QoS menu
8.1 QoS Configuration
In the QoS configuration tab, the packet classifier can be managed to define a QoS rule for incoming
Ethernet traffic, and assign a priority to be used in the G.hn network. Press the “Update" button for loading
the newly configured settings:
QoS CRITERION: a general criterion can be chosen among "None" (no QoS), "Custom" and
"802.1p".
Type of Frame: with this parameter the type of Ethernet traffic being transmitted by the G.hn
network should be selected. Based on this parameter, the internal offsets in the system are adjusted.
In the QoS tab, Ethernet frame offsets should be set counting number as they appear in the sniffer
SW (for instance, the same field will be in a different position if normal Ethernet frames or 802.1Q
tagged frames exist).
Packet detection 1: first packet detection rule can be configured (offset, bitmask and pattern).
Packets which accomplish it will be sent to the classification module.
Packet detection 2: if second packet detection is also enabled, both, first and second detection
criteria must be accomplished to pass packets to the classification module.
Packet classification: up to 8 classification rules can be defined in this section for packets which
have previously been correctly detected. For 802.1p only priorities can be managed, offset, bitmask
and pattern are predefined to sniff the PCP field.
Default priority: select default priority; which will be applied to non classified incoming packets.
Priority 7 is the highest. Priority 0 is the lowest.
