Updated: Sep 18
When you order a new nbn® service, you may hear terms like Service Class 12 or Service Class 24. These “service classes” are codes used by nbn® to describe the current state of the connection at your property. Each service class indicates:
What type of technology is at your address.
Whether the necessary cabling or equipment is installed.
If a technician is required before you can go live.
Understanding Service Classes
Understanding service classes is crucial for a smooth connection experience. Here’s a breakdown of the different service classes based on technology types.
FTTP (Fibre to the Premises)
Class 0: Planned for fibre, not yet ready.
Class 1: Fibre available but no connection box (NTD) installed.
Class 2: External equipment installed, but internal NTD still missing.
Class 3: Fully ready — NTD installed and service can be activated quickly.
Fixed Wireless
Class 4: Planned but not ready yet.
Class 5: Serviceable, but antenna and/or NTD not installed. Technician required.
Class 6: Antenna and NTD already installed — can usually be activated remotely.
FTTN / FTTB (Fibre to the Node or Building via Copper)
Class 10: Planned, not yet ready.
Class 11: Copper available, but jumpering or lead-in work required.
Class 12: Copper line connected at the node — can usually be activated without a site visit.
Class 13: Fully serviceable and ready for activation.
HFC (Hybrid Fibre Coaxial)
Class 20: Planned for HFC, not ready yet.
Class 21: Lead-in required; NTD not installed.
Class 22: Lead-in complete, but wall plate or NTD missing.
Class 23: Lead-in and wall plate installed, NTD still required.
Class 24: Lead-in, wall plate, and NTD all installed — ready for activation.
⚠️ Important: In some cases, the HFC NTD (nbn® modem) may have been removed from the premises by a previous occupant. If this happens, a replacement NTD must be ordered before you can connect. First Responder Broadband can arrange this for you.
FTTC (Fibre to the Curb)
Class 30: Planned, not ready yet.
Class 31: Lead-in exists but premises not yet connected.
Class 32: Lead-in in place, but the nbn® connection device (NCD) not installed.
Class 33: NCD required, connection mostly ready.
Class 34: NCD installed — service ready to activate.
⚠️ Important: Similar to HFC, the FTTC NCD may have been removed from the property. If this is the case, a new NCD needs to be ordered before activation. First Responder Broadband will assist with this process to ensure you can get online.
