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.
Summary:
A working Openreach unit has green: power, PON & LAN lights, anything else indicates a problem.
More info
- Newer ONT installs do not include a Battery Backup Unit (BBU)
- 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.
