Carrier Provisioning: ISPs remote-flash ONTs via ACS (TR-069), pushing device-specific configs, VLAN profiles, and firmware images. XPON images let carriers standardize hardware across GPON/EPON footprints.
Auto-Provisioning Flow: Device boots → fetches ACS URL via DHCP options or bootfile → authenticates → downloads configuration and firmware as needed.
Rollback & Fail-Safe: Robust deployments include an A/B partition or dual-image boot to allow rollback if an upgrade fails.
