Traffic Class 4

The important things you need to know when migrating business services to the nbn® network.

Introducing Traffic Class 4 (TC4) – Designed for business internet and standard data services

We offer three wholesale traffic classes to service providers (TC1, TC2 and TC4), which they use to create products to sell directly to you.# Each traffic class has a different primary purpose;

TC4 is designed primarily for general internet and standard data services and has the following features:

  • Available across all access technologies.
  • Asymmetrical wholesale download and upload speeds*
  • A ‘best effort’ service suitable for non-critical business data applications

Traffic Class 1 (TC1) is designed for voice (specifically for Voice over Internet Protocol [VoIP] services), and Traffic Class 2 (TC2) is designed to accommodate many business-critical data services such as video conferencing.*
