Sagemcom 5290 Transparent Passthrough Mode + Wifi Question

Were getting frontier fiber at one of our business sites. From what I understand Sagemcoms bridge mode is called "Transparent Passthrough Mode" Is this available on the 5290 model?

Also they are using wifi for their phones (lulz) will passthrough mode be possible in this configuration?

Any help is appreciated. I need to be onsite tomorrow morning, and I can't find a fucking manual anywhere.

Thanks.
