The Openreach ONT is actually inside an enclosure which also contains a Battery Backup Unit (BBU) and various wiring.

The ONT requires power, so will need a mains power socket nearby.

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]]
=LED STatus=
 
=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 a Battery Backup Unit (BBU) See: [[999_and_faults]]
The* Older Openreach ONT (Optical Network Termination) such as the one pictured, is actually inside anthe enclosure. whichThis also contains a Battery Backup Unit (BBU) andalong with various wiring and cable management.
* 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]]
