ᐅ Two-family house, one telecommunications connection – questions

Hello everyone,

I built a two-family house together with my parents-in-law, and their living area is rented out.
During the construction, we had a new connection installed by the telecom provider in my garage.
So, there is a distribution point in my garage, and for my own unit, an additional outlet from the telecom provider.
Each living unit has a CAT7 cable running to this distribution point.

Now, the upcoming tenant wants to sign a contract with O2 for phone and internet service.
O2 is asking for written confirmation that a cable from the apartment to the distribution point exists.

Is this normal? Do I need to inform the tenant or O2 that they can install an outlet in my garage and that I will ensure the connection to the rental unit?
Or what would you suggest? I just want to understand the usual procedures and make sure I don’t make any mistakes.

Of course, I have to schedule the installation appointment with O2 since the tenant has no access to my garage.

I appreciate any advice or tips.

Best regards,
Tito

O2 is said to have confirmed that there is a "first wall socket" (TAE) at the tenant's premises. However, only a network operator is allowed to install this or connect it to the building termination point (BTP). Apparently, they do not want to be the initial service provider for a customer in this case, but rather just take over where Telekom has already installed a line and a network termination.

Your idea that the O2 technician would install their exclusive wall socket in your garage for the tenant is, as far as I know, not exactly prohibited but also not ideal. The tenant is unlikely to want to plug their router into there. Tapping off at a Category 7 wall socket (or whatever term a DIYer or local electrician might use) is not possible without, to put it mildly, some loss of quality.

According to your plan, the tenant could essentially enjoy flawless analog telephony—triple play services would be less likely.

Hello 11ant,

thank you for your reply.
Currently, we have the following "boxes" from Telekom in the garage.
I believe one of them is the demarcation point, and the other is the telephone outlet (TAE socket).

My electrician set it up so that a CAT7 cable runs to each residential unit’s electrical panel, where the router can be connected. From there, all LAN cables run to the rooms within each unit.

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

Why is this setup likely to cause a loss in quality?
Basically, I would need to share exactly what I described here with O2 so they know what is available and what is needed, correct?

Regards

This box, as shown in the photo, and the associated enclosure belong to the telecommunications provider. O2 has no involvement with it. Caution. Your responsibility begins only beyond this installation.

Okay, good to know...
If I remember correctly, Telekom left two red wires exposed before their TAE socket.
Can O2 then install their own TAE socket on this? Is this perhaps what I need to confirm with O2?
I can take a picture of it tomorrow, but there is a 99.9% chance that the two exposed wires between the box and the TAE socket are red/white.

I don’t see any photos here (?), but for me, they’re not necessary. O2 first needs a subscriber line from the exchange to the demarcation point (which you refer to as the handover point). From the demarcation point to your telephone connection outlet (TAE), there is a four-core cable with only two wires in use – your assumption that the other two could be used for this purpose is technically incorrect and legally irrelevant anyway.

1) No, they have to coordinate with Telekom about who installs the monopoly TAE – preferably inside the apartment – and this monopoly TAE is then operated separately from the demarcation point. 2) O2 will want confirmation that this monopoly TAE already exists, which in turn requires an existing Telekom subscriber line. Therefore, O2 will most likely reject the customer since they cannot rent a "ready" subscriber line (TAL) to them.

The TAE can also be located next to the electrical panel, but the cable between the demarcation point and there should be Telekom cable (quad cable wired in a star topology).

My electrician solved it by running a CAT7 cable to each housing unit’s respective electrical panel, where the router can be connected. From there, all LAN cables go to the various rooms of each unit.

It is called Cat.7 because 93% of all electricians have absolutely no idea what that means ;-)
