Calix (what I run) and most other platforms you provision the services to the ONT using a profile that defines the speed available and priority level, which is a feature built into the PON MAC standard. It allows you to define high priority vs guaranteed speed vs best effort traffic services but does not do any per flow management or polite QoS or DPI.
We have gotten complaints before from a customer who moved from a Preseem FQCodel enforced wireless plan to the same speed plan on Calix PON, because of this. We decided to consider that an upsell opportunity because those are usually the lowest plan customers.
