Duplex house, one telecom connection - questions

Hello everyone,

I built a two-family house with my parents-in-law, whose living area is rented out.
During the construction of the house, we had a new connection installed through Telekom, in my garage.
So we have a handover point in my garage and an extra Telekom socket for my own residential unit.
Each residential unit has a CAT7 connection cable to this handover point.

Now the soon-to-be tenant wants to sign a contract for telephone and internet with O2.
O2 now wants written confirmation that a line from the apartment to the handover point exists.

Is this normal? Do I have to inform the tenant or O2 that they can install a socket in my garage and that I ensure a connection to the rental property?
Or what is your suggestion? I just want to understand how the usual procedures are and not make any mistakes.

Logically, I have to arrange the appointment for setting up the connection with O2, since the tenant has no access to my garage.

I am grateful for any suggestions and tips.

Best regards, Tito

O2 claims to have confirmed that there is a "first TAE" at the tenant's premises. However, only a network operator is allowed to install it or connect it to the ApL ("handover point"). Apparently, they do not want to be the primary provider for a customer there, but rather just move into a situation where Telekom has already laid down a line and a network termination. Your idea that the O2 technician installs his monopoly TAE in your garage for the tenant is, as far as I know, not exactly prohibited, but not ideal either. The tenant is unlikely to want to plug their "router" there. Tapping off at a TAE Cat.7 (or whatever the DIYer or village electrician calls it) does not succeed without, to put it mildly, "loss of quality". According to your concept, the tenant will be effectively provided with flawless analog telephony – but rather less so with Triple Play.

Hello 11ant,

thank you very much for your response.
Currently, we have the following "boxes" from Telekom in the garage.
I think one is called the handover point and the other is the TAE socket.

My electrician solved it so that a CAT7 cable is run to each residential unit up to the respective fuse box, where the router can then be connected. From there, all LAN cables run to all rooms of the respective residential unit.

So the tenant installs their router centrally in the fuse box and receives the signal via the CAT7 cable from the garage... if O2 then installs a socket there.

Why is a loss of quality to be expected with this variant?
Basically, I would have to pass on exactly what I have described here to O2 so that they know what is available and what is needed, correct?

Regards

This box, see photo, the can with it, belong to Telekom. O2 has no business with it. Caution. Your freedom begins only behind this installation.

Ok good to know... If I remember correctly, Telekom left two red wires open before their TAE socket. Can O2 then install their own TAE socket there? Is that perhaps what I have to confirm to O2? Tomorrow I can take a picture of it, but 99.9% the two open wires between the box and the TAE socket are red/white.

I don't see any photos here (?), but they are not necessary for me either. O2 initially needs a subscriber line from the exchange to the ApL (what you call handover point). From the ApL to your TAE, there is indeed a four-wire cable with only two wires used - your idea that the other two could then be used for the project is technically incorrect and legally to be disregarded anyway.

Can O2 then install its own TAE socket there? Is that perhaps what I have to confirm to O2?

1) No, they have to quarrel with Telekom about who installs the monopolistic TAE – preferably in the apartment – and the monopolistic TAE is then separately connected from the ApL. 2) O2 will want to hear that this monopolistic TAE already exists, which however presupposes an existing previous Telekom subscriber line. Therefore, O2 will probably reject the customer because they cannot rent a "ready" TAL to him.

The tenant thus installs his router centrally in the fuse box and receives the signal via the CAT7 cable from the garage.... if O2 then installs a socket there.

His TAE can certainly also be next to the fuse box, but the cable between the ApL and there should be Telekom cable (star quad).

My electrician solved it so that a CAT7 cable runs to each fuse box in each residential unit, where the router can be connected. From there, all LAN cables also run into all rooms of the respective residential unit.

It’s called Cat.7 because 93% of all electricians have absolutely no idea about it ;-)
