Code of Conduct
Power states
Code of Conduct provides rules for the power consumption in:
Full power state:
This is the normal operation mode of the device, where all functionality is enabled.
Low power state:
When there is no user traffic on the device, the device should switch to low power mode. This is a state in which devices
are only allowed to use a limited amount of energy to be able to power its components and respond to user activity.
Example
Take the following example:
The user switches off his computer at 20:00.
There are no other devices connected to the MediaAccess Gateway.
The MediaAccess Gateway switches to low power mode. This results in a considerable drop in the overall power
consumption of the MediaAccess Gateway.

Introduction
The MediaAccess Gateway constantly monitors the user activity and uses this information to optimise the power
consumption:
For example:
The MediaAccess Gateway
reduces the clock frequency of the central processor
when there is no or low user activity.
This lowered clock frequency will result in a lower power consumption of the MediaAccess Gateway.
Disable the USB port(s)
when they are not used
Switch the wireless interface to power reduction mode
.
Wireless access point power reduction mode
When the MediaAccess Gateway access point switches to power reduction mode, the access point is switched off and is
only power on periodically to be able to detect new clients. If new clients are detected the wireless access point is fully
powered again. This is only possible if there are no devices connected to the MediaAccess Gateway.
Power reduction is enabled by default, but it is possible to disable it via the MediaAccess Gateway GUI. To configure power
reduction:
1
Browse to the MediaAccess Gateway GUI.
For more information, see
“Accessing the MediaAccess Gateway GUI” on page 33

.
Example
If we use the same example as in the previous section, you can see that the MediaAccess Gateway is now able to further
reduce the power consumption in periods where less action is required from the MediaAccess Gateway.

Manually Switching Off Services to Reduce Power
ECO button
If you are not using the wireless access point of your MediaAccess Gateway, you might consider to disable the wireless
access point permanently. This allows you to further reduce the power consumption.
To turn the wireless interface:
Off
, press the
ECO
(
) button until the Wireless LED is off.
On
, press the
ECO
(
) button until the Wireless LED is on.
Zero power consumption
If you will not be using your MediaAccess Gateway for a longer time (for example: you are going on holiday), you should
consider to turn off the MediaAccess Gateway. This way no energy will be consumed at all.
However, be aware that if you turn off the MediaAccess Gateway,
all services provided by the MediaAccess Gateway that
require access to the Internet will not be available
. For example:
You will not be able to browse to Internet websites, listen to radio streams etc.
No VoIP calls can be made/received
You will no longer be able to make or receive phone calls over the Internet. Your phone calls will automatically be done via
the traditional phone network (if available).
No Digital TV is provided
If your set-top box is connected to your MediaAccess Gateway, it will no longer be able to connect to the Internet, hence
not be able to service your TV set.
