Customer router connects to yellow socket]] 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]] The ONT requires power, so will need a mains power socket nearby.▼ =Summary:= ~~=LED Status=~~ 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 ~~the~~a ~~BBU,~~Battery ~~and~~Backup ~~are~~Unit ~~also not in a~~(BBU) ~~larger~~See: ~~enclosure.~~[[999_and_faults]] ▲* 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. ▲* 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.
