Adapter Configuration |
|
|
|
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 |
|
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 | 29 |
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 wall mount 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 wall mount adapter can be reset without any risk, but the old firmware will still be present on the adapter.
