For apartments and units. Fibre runs to your building, and the building's phone wiring carries it to your home.

## About FTTB

- **How it connects**: Fibre runs to a communications room in your building. The building's copper phone wiring connects it to the phone socket in your unit.
- **What you need**: A VDSL2 modem-router plugged into your phone socket. Set its internet connection to Dynamic IP (DHCP). There is no PPPoE login and no VLAN tag.
- **Speed**: The copper inside a building is usually short, but its condition varies from building to building.
- **Power**: NBN® services don't work in a power outage, and you can't make calls over them, including to Triple Zero (000).

**Your line speed.** Your line may not reach a plan's top speed. After connection we check your line's maximum attainable speed. If it can't support your plan, you can move to a lower plan with a pro-rata credit, or cancel with no exit fee.

## Frequently asked questions

### Why does my modem need to be VDSL2?

FTTB carries your internet over the building's copper phone wiring using VDSL2. A router without a VDSL2 modem built in can't connect to it.

### How do I know if I have FTTB?

Check your address at https://crazytel.com.au/crazynbn/fttb/. We'll show your connection type, and if it isn't FTTB, we'll take you to the right plans.

### Is there a contract?

No. Every plan is prepaid and month to month, with no lock-in contract and no exit fees.

### Can I change plans later?

Yes, any time. Your old plan is credited and the new plan is charged pro-rata. Upgrades need enough balance to cover the difference.
