# FTTN/B (Fibre to the Node/Basement) or VDSL2

Check and note down the status lights of the VDSL2 Modem

* Power
* Sync/DSL
* Internet/WAN
* Ethernet/LAN

Note: Include if blinking or solid

Ensure SRA (Seamless Rate Adaption) is enabled, and if possible, in Dynamic mode for both upstream and downstream

{% tabs %}
{% tab title="Service Outage/Offline - No SYNC, No DATAFLOW (including inability to authenticate)" %}
**Pre-checks/Troubleshooting**

* Verify that the VDSL2 modem onsite is connected to the Telephone wall socket correctly. Ensure that internal wiring has no issues
* Has another Telephone Line Cable and VDSL2 modem tested? (Test the telephone line cable)

**Perform nbn diagnostics check via the Partner Portal NBN Self-Diagnostics Tool**

* Perform Line State Test to check the current operational status of the DSLAM port. If the DSLAM port is in an operationally up state, but the CPE modem indicates no sync, proceed to the next step. If the DSLAM port operational state and the CPE modem sync state do not align, raise a fault.
* Perform Port Reset to fix VDSL2 modem sync issues. Ensure you wait around 3-4 minutes after the reset completes to allow the CPE modem to attempt to sync before conducting further testing, or the results may be invalid.
* If the modem is still not able to get sync, there could be a bridge tap or a connection issue inside or outside the premises. Raise a fault.
  {% endtab %}

{% tab title="Service Degradation/Speed Issues" %}
**Pre-checks/Troubleshooting**

* Has another Telephone Line Cable and VDSL2 modem tested? (Test the telephone line cable)
* Perform an isolation test by plugging laptop/computer directly into the VDSL2 modem via ethernet cable and run Hosted Network’s WAN Diagnostic Tool. Ensure all other devices are disconnected for accurate results
* If slow speeds are not experienced on isolation tests, it is potentially a CPE issue. If slow speeds continue to be experienced, continue to the next step.
* Confirm with the End User if the speed issues are constant or only occurring at specific times. If the speed issues are constant, raise a fault. If the speed issues are only experienced at certain times of the day, capture this information from the End User before raising a fault and re-run the speedtest outside these certain times of the day.
* Check the CPE if capable of handling the expected speed (Interface, configuration, etc.)
  {% endtab %}

{% tab title="Dropouts" %}
**Pre-checks/Troubleshooting**

* Has another Telephone Line Cable and VDSL2 modem tested? (Test the telephone line cable)
* Check the CPE for any issues and consider firmware upgrades
* Ensure that internal wirings has no issues
