Telekom ONT with O2

Hello ​@Nawart ,

Welcome to the community.
We're delighted that you're interested in a fiber optic connection with us. 
You can also use the router with a connection from us. However, you cannot use the ONT, as it is tied to a DTAG connection. You will need to get a new one.

You can find instructions for your router from the manufacturer. 

Best regards
Maria

​@o2_Maria , So what type of ONT i can get, any ONT can work or only spesifc ones? from the website when i’m trying to initiate the contract, i don’t see any option for ONT , only Firtzbox routers with builtin Modems.

Thank you 

When you are on the page to choose the router, you have to select that you want to use your own:

Later in the process, you have to enter your Modem ID which is the ID of your Telekom modem. 

Inside “Schnittstellenbeschreibung” (https://www.telefonica.de/impressum/schnittstellenbeschreibungen-der-betreiber-oeffentlicher-tknetze.html) you can read all about the requirements of the ONTs to use. 

Hello ​@Nawart ,

It's great that 5G_Tester has already provided such excellent support here.
Did this post help you, or do you still have questions?

Best regards
Maria

Thank you ​@5G_Tester and ​@o2_Maria ,

Thank you all

Thank you ​@5G_Tester , it is my own device

Hey ​@Nawart ,

I’m happy to see that 5G_Tester was able to answer all your questions 😊 have you ordered the fiber connection with us yet? 

If you like, keep us posted on the installation process and let us know if any further questions come up 🌻

Kind regards, Rebecca

Hello ​@Nawart,

have you succeeded with the connection?

I have the same problem, I connected Telekom ONT, changed Modem ID on the O2 portal, but the ONT is blinking green continuously, means no link established. After I changed Modem ID, my FritzBOX has lost fiber connection, means changes have been applied.

​@VolodymyrD , no not yet, my contract starts April , but i hope ​@5G_Tester  can help you

Hello ​@Nawart,
we're glad that the tips from 5G_Tester helped. Please keep us updated here to let us know if everything worked out.
Kind regards, Bianca

Hello ​@VolodymyrD,
thank you for posting your question here in the community. What is the current situation? Is everything working now, or can we still help you?
Kind regard, Bianca

Hello ​@o2_Bianca,

the situation is unchanged, still no answer or solution. So far I use FritzBox in bridge mode to passthrough PPPoE connection to my UniFi gateway, but would be happy to get rid of it and replace with Telekom ONT.

Hey ​@VolodymyrD ,

The Telekom ONT you have must be “registered” with us. The best way to do this is by phone. You can also contact our English hotline:
