Problems with Telekom. Crossed cable?

The lines will probably be activated after the order is received, and the neighbors must have reported earlier.

That is little. You can gladly write to me, at gmx (de) I have the same name as here, maybe a solution can be found.

Thank you
I will write to you during the morning.

Best regards

and if you book a higher plan, do you get a higher faster volume?

Sounds like there are no ports left free on the linecard.

Instead of calling the hotline, I would try to contact the Telekom Hilft Team in writing. I find the staff there more competent than those in the call center. Telekom either has its own support forum, but these are also active in various computer forums. You can enter Base and Computer into a search engine.

Good luck.

This simply means that your KVZ (cable distribution box - small gray box on the street) is not directly connected to an MSAN (DSL server - large gray box with ventilation slots in the lid), but that a copper cable was laid between an existing MSAN and the KVZ to which the area is connected, or an existing cross-connection was used. When that is full, it's a problem, because there are only 3 options: civil engineering work (which won't be done for just one connection), Telekom upgrading your KVZ with an MSAN (which won't happen because of the proximity to the other MSAN), or a neighbor moves out and cancels their internet (have you ever thought about the neighborhood being bombarded with folk music?!).

Your internet would then run several kilometers from the KVZ to the switching center, hence the 6 Mbit due to high line attenuation.
Your neighbors' signal takes a shortcut at the KVZ with a few meters to an MSAN located somewhere nearby.

It sounds like there are no more ports available on the linecard.

That would be another "line shortage" – the experienced T technician is notified of this, and if you call it a crossover cable, that's usually correct.

A new LC would actually be the lesser problem for him, because upgrades are usually done quickly there.

and if you book a higher tariff, do you get higher faster volume?

I would book immediately! More than 6 Mbit/s is not possible.
