Here the products in the Mesh are designated with a corresponding "Mesh active" icon. A FRITZ!Repeater or FRITZ!Powerline adapter with FRITZ!OS 7.00 or higher installed can be enabled for Mesh in various ways: - If the product has the factory settings configured and is being connected with the FRITZ!Box for the first time, it will be automatically enabled for Mesh. - If the product is already connected, but not enabled for Mesh, it is added to the Mesh by pressing a button on the product to be integrated and a button on the FRITZ!Box. On the FRITZ!Box, use the button that initiates WPS (depending on the model, press the "Connect" or "WPS" button briefly, or the "WLAN/WPS" button for 6 seconds). Detailed instructions, additional information and the answers to frequently asked questions about Mesh are presented at en.avm.de/mesh-faq. ------------------------------------------------------------- ****Mesh for Telephony and Smart Home**** With FRITZ!OS 7.0, telephony and Smart Home are also compatible with the Mesh. The connections of cordless telephones and Smart Home products are displayed in the FRITZ!Box Mesh Overview. You can use a second FRITZ!Box as Mesh Repeater, and use telephones registered with the second FRITZ!Box with the numbers assigned in the first FRITZ!Box, the "Mesh Master". ------------------------------------------------------------- **Configuring a Second FRITZ!Box as a Mesh Repeater with the Press of a Button** Prerequisites: - Your existing FRITZ!Box supports Mesh (FRITZ!OS 7.00 or higher). - The FRITZ!Box to be deployed as a Mesh Repeater has been updated to FRITZ!OS 7.0 and you have restored its factory settings. Here's how: - Connect the port "LAN 1" of the Mesh Repeater with the Master using a LAN cable. - Initiate the Connect function on both boxes. After the connection procedure is concluded, the second FRITZ!Box is ready for operation as a Mesh Repeater. (It is operating in "IP client" mode and, as a Mesh Repeater, adopts the wireless LAN settings and other important settings from the FRITZ!Box). Please note that this function can be used only if the second FRITZ!Box is permanently connected with the first box by LAN cable. If you received the second FRITZ!Box from your internet provider, the automatic configuration of this feature might not be possible. In this case, configure this FRITZ!Box manually in the user interface as Mesh Repeater. For instructions, see en.avm.de/mesh-faq. ------------------------------------------------------------ **Transmitting the Telephone Numbers of a Mesh Master to Another FRITZ!Box in the Home Network** Once you have added an additional FRITZ!Box to the Mesh, you can configure it so that all telephone numbers are available on each FRITZ!Box. If your FRITZ!Box is connected with a landline, you can use the telephones connected to the second FRITZ!Box to make calls over the internet as well as on the landline. If at least FRITZ!OS 7.0 is installed on both FRITZ!Boxes, the telephone numbers are transferred automatically in the Mesh once the "Telephony in the Mesh" option is enabled. If the new FRITZ!Box is already a component of the Mesh, or if you have already set up telephone numbers on it, these telephone numbers must be deleted and one of the two FRITZ!Boxes must be restarted. Then the new FRITZ!Box must be enabled for "Telephony in the Mesh". To do so proceed as follows: - Click "Home Network" in the user interface of the Mesh Master. - Click "Mesh" in the "Home Network" menu. - Click the "Mesh Settings" tab. - In the "Use Telephony in the Mesh" section, click the "Enable" link next to the respective Mesh Repeater and then confirm that the procedure may be executed on the Mesh Master as well, if asked to do so. The telephone numbers are now distributed in the Mesh and can be assigned to your telephones and other terminal equipment for telephony (for instance, answering machines) on the FRITZ!Box. Note: Telephony Mesh is not the same thing as DECT repeating, which requires the support of special hardware on the FRITZ!Box deployed as the Mesh Master. If you would like to use DECT repeating, you can purchase the FRITZ!DECT Repeater 100 from an electronics retailer. ___________________________________________________________ Instructions for installing the update: Use the update function offered in the user interface to install the update. This automatically offers you the right FRITZ!OS. Click "Wizards", select "Update" and then follow the instructions on the screen. ___________________________________________________________ Š FRITZ!
