The Boost Wifi device is not a router, just a Mesh Access point, so cannot be connected to the bridged port of your Telus Actiontec T3200M.
To my knowledge, other than the initiating Boost Device, all the satellites are Wi-Fi connected, not Ethernet connected. The satellite device Ethernet port CAN be used to connect an Ethernet device to your network. For instance, you could connect a desktop computer lacking a Wi-Fi card to one of the satellites and connect to your network.
You also can't daisy chain the Boost devices, as there is only one Ethernet port on them.
If your home is constructed such that a Wi-Fi mesh would not work well, you may be better to choose Access Point devices specifically created to connect by Ethernet.
