What is the difference between NBN Traffic Classes?
NBNCo offers wholesalers three traffic classes.
Traffic Class 4 is the standard, ‘best-effort’ service that most people are familiar with. TC-4 is suitable for most general purpose applications, but offers no guaranteed bandwidth. Speeds are asymmetrical.
- 12Mbps / 1Mbps
- 25Mbps / 5 Mbps
- 25Mbps / 10Mbps
- 50Mbps / 20Mbps
- 100Mbps / 20Mbps
- 100Mbps / 40Mbps
- 250Mbps / 25Mbps
- 250Mbps / 100Mbps
NBN Fixed Wireless services support only 12/1, 25/5 and 50/20 plans. Speeds over 100Mbps require Fibre to the Premises.
Traffic Class 2 offers symmetrical download and upload speeds with a guaranteed minimum Committed Information Rate (CIR) and maximum latency, jitter and packet loss.
Zero Point Networks doesn’t offer Traffic Class 2 services, as these requirements are met by our Enterprise Ethernet solutions
Traffic Class 1 is designed for Business Voice services. It guarantees the full amount of bandwidth will always be available.
- 1 fixed phone line
- Up to 2 concurrent phone lines
- Up to 3 concurrent phone lines
- Up to 6 concurrent phone lines
- Up to 12 concurrent phone lines
- Up to 25 concurrent phone lines
What should we use?
For most small businesses, TC-4 NBN is adequate, but if you rely heavily on your phones it may be worth considering a dedicated TC-1 NBN connection for your phone system. If an interruption to your Internet service would cost you money, consider SD-Internet or Enterprise Ethernet.
