Openreach FTTP ONT: Difference between revisions

Revision as of 19:16, 13 April 2022

(Newer) Openreach single port ONT

(Newer) Openreach single port ONT ports

(Older) Openreach ONT, powered off!

(Older) Openreach ONT, powered on and working OK

(Older) Openreach ONT, cover removed. Customer router connects to yellow socket

This page is about the FTTP termination device that Openreach install for FTTP customers.

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.

LED Status

Openreach ONT LED Status
LED	Colour	Meaning	Notes
Top (ONT) LEDs
TEL1	Off		We don't use the Tel ports
PORT1 or LAN	Blinking/Flashing green	Data being transmitted	Good
PORT1 or LAN	Off	ONT has no ethernet link to the router	Bad. Check the connection/cable to the router
LOS (Loss of service) PON (Passive Optical Network)	PON solid green, LOS off	Connected and should be working	Good. This is how it should be normally
	PON flashing green, LOS off	ONT is starting up	Wait a bit for steady green and all should be well...
	PON off, LOS solid red	Possible fault with the fibre	Bad. Check fibre not damaged, reconnect fibre, power cycle ONT
POWER	Solid green	Device has power	Good
POWER	Off	Power is off	Bad. Check mains power and connection to BBU/ONT
Bottom right (BBU) LEDs
STATUS	Solid green		Good
STATUS	Off
FAULT	Solid red	Battery fault	Bad. Replace the AA batteries inside
FAULT	Off		Good. No fault
CHARGING	Solid orange	Batteries are not fully charged	Wait; the batteries are charging (usually after a power cut)
CHARGING	Off	Batteries are not being charged	Good. The batteries are fully charged
