Speed Limitations for NTD’s
For NBN services that are installed with an NTD, there are specific speed limitations associated. This is primarily for customers intending to provision multiple services (on different UNI-D ports) on a single NTD.
The limitation on the NTD, as it is classified as Traffic Class 4: Up to 1000/400 Mbps. It is not a limitation on the network. Basically, the NTD will only support up to 1000 Mbps in total.
Example:
2 NBN services, each with 500Mbps, or
1 NBN service with 1000Mbps.
