This page is about the FTTP termination device that Openreach install for FTTP customers. ONT stands for Optical Network Terminal, sometimes (mistakenly) called an openreach modem. CityFibre use a different ONT - we have a separate page on that: [[CityFibre ONT]]
=Summary:=
* In short, the ONT in installed inside the customer's premises by CityFibre and converts the fibre connection from the outside world in to a RJ45 port which you plug in to your router with a CAT5 cable.
* The ONT requires power, and a UPS is recommended, see our [[VoIP_Power]] page for suggestions.
Openreach provide an ONT for use with FTTP services. - so when you order a BT-based FTTP service from A&A, an Openreach engineer will install the little ONT unit in your premises. You then connect your Ethernet router to it and set your router with the A&A PPP credentials to log in.
This page is about diagnosing problems with the Openreach ONT.
* A working Openreach unit has '''green: power, PON & LAN''' lights, anything else indicates a problem.
* Your PPPoE capable router will plug in to the LAN port and connect you to the internet.
=More info=
* Newer ONT installs do not include
* Older Openreach ONT (Optical Network Termination) such as the one pictured, is actually inside the enclosure. This also contains a Battery Backup Unit (BBU) along with various wiring and cable management.
▲* Newer ONT installs do not include the BBU, and are also not in a larger enclosure.
* The ONT requires power, so will need a mains power socket nearby.
* Where provided, the battery has a short warranty, and should be maintained by the end user, however, the battery is to keep the unit powered so that the TEL ports can be used during a power outage - we don't use the TEL ports, so you will want to make other arrangements for using a phone during a power outage - eg a mobile phone. See: [[999_and_faults]]
* At least newly installed BT ONTs support Baby Jumbo frames (see [[MTU]])

Openreach will usually install a junction box on the outside of the property. This connects up the fibre from the street to the fibre that goes inside the property.
This is a passive device, doesn't require power, and is just used to connect the two fibres together. The photo shows both a Brown CityFibre unit and a Grey Openreach unit.
