MA5680T GPON ONT VLAN transparent transmission problem

I would like to ask how the transmission function with MA5680T   ONT VLAN, i.e. ONT pass through all of the VLAN business?

There are many transparent keyword command, should be different meanings in different places?

For example, line template under gem mapping, the port VLAN business template has the transparent keyword.

Also in the template TLS specifically what is the meaning?

What is this? Like or not.
