Is TP-Link VDSL modem SOS-ROC Compliant?

Recently, we received some feedback that NBN is going to implement 2 new functions SOS (Save Our Showtime) and ROC (Robust Overhead Channel) to VDSL2 lines (FTTN and FTTB) at the end of March 2022 (now being postponed). NBN users are curious about whether TP-Link has any DSL products that support SOS and ROC. We will list some questions that you are concerned about in this FAQ.

Q1: Does TP-Link have DSL models that support SOS and ROC?

A1: Currently, we don't have a model that supports SOS and ROC yet. But there has been a plan to support it on some models via a firmware upgrade.

The following table is for your reference. If your model is not included, please don't worry since most models support SRA which is enough to keep a stable connection on an SOS/ROC enabled VDSL2 line.

Note: Plan is not a guarantee, the planned models' list will be updated and TP-Link reserves the right to update the FAQ at any time without notification.

Q2: Will there be any problems with my service after NBN deploys SOS and ROC?

A2: NBN does not mandate that DSL modem routers must support SOS and ROC. For DSL modem routers not supporting these new functions, another function, Seamless Rate Adaptation (SRA) will be required to ensure connectivity under certain noisy conditions. Most TP-Link DSL modem routers support SRA. After SRA is turned on, even if NBN deploys SOS and ROC, the DSL modem router can maintain a stable connection.

How to enable SRA on the TP-Link DSL modem router?

Log into web UI and go to Advanced > Network > DSL Settings > enable SRA
