NBN FTTN - Level 1 Checks

NBN FTTN - Level 1 Checks

The NBN Level 1 Checks for FTTN (Fiber to the Node) are a series of troubleshooting steps aimed at diagnosing and resolving issues related to the VDSL (Very High Bit Rate Digital Subscriber Line) broadband service. Let's elaborate on each of these checks:

1. **VDSL Modem/Router Rebooted for this Service**:

   - This step involves restarting the VDSL modem/router that provides internet access to your FTTN service. It is a common troubleshooting practice to ensure that the modem/router is functioning correctly and to refresh its connection to the network. Rebooting can resolve minor connectivity issues and helps establish a stable connection.

2. **Checked Telephone Cable from the Phone Socket to the Modem**:

   - Here, the technician or user inspects the telephone cable that connects the phone socket (usually a wall socket) to the VDSL modem. The purpose is to verify that the cable is not damaged, frayed, or otherwise compromised. Additionally, the connection should be secure to prevent signal loss or interference.

3. **Performed a Line Isolation Test**:

   - A line isolation test involves disconnecting all devices, such as phones, fax machines, or other equipment, from the PSTN (Public Switched Telephone Network) phone line, except for the VDSL modem. The goal is to isolate the VDSL modem and check if the issue is related to other devices connected to the same line. If the problem is resolved during this test, it indicates that one of the disconnected devices may be causing interference.

4. **Tested an Alternate VDSL Modem**:

   - In this step, an alternative VDSL modem is used to test the service. This alternative modem is known to be in working condition. The MAC (Media Access Control) address of the alternative modem may be required for record-keeping. This test helps determine whether the issue is specific to the original modem or if there are broader network or line issues.
if the router is provided by NetVault, please skip this step.

5. **Checked Building Internal Cabling/Wiring**:

   - The final check involves inspecting the internal cabling and wiring within the building to ensure there are no faults or issues outside of the carrier network's responsibility. This includes looking for problems such as loop impairments (where the signal loops back on itself) and bridge taps (extra wires connected to the line that can disrupt the signal). If issues are found here, they may require the services of a professional technician to resolve.


These Level 1 checks are systematic troubleshooting procedures designed to diagnose and potentially resolve common FTTN internet service issues. If the problem persists after these checks, further investigation and potentially more advanced diagnostics may be necessary, please contact us at support@netvault.net.au
