DSL: widely available, but line length matters
Before you sign a DSL contract, it pays to check which data rate is realistic on your line – with line length, upload, router costs and the product information sheet at a glance.
DSL usually uses the telephone line for the final stretch. The performance you can actually get depends on factors such as line length, network build-out and the wiring in your building. That is why availability and the product information sheet (Produktinformationsblatt) matter more than the tariff name.
When DSL is a good fit
DSL can be a sensible choice if stable speeds of 50 to 250 Mbit/s are offered at your location and several providers are available. For normal household use, you don’t automatically need the highest tier you can book.
- Widely available
- Often several providers to choose from
- Predictable tariff structures
- Upload usually lower than download
What to check in the contract
Compare the minimum, normally available and maximum data rates stated in the product information sheet. Also check whether router rental, a connection fee or delivery costs are added.
Frequently asked questions
Is VDSL the same as fibre?
No. With VDSL, the fibre usually only reaches a street cabinet; the last stretch to the building runs over copper. FTTH brings fibre all the way into the flat or building.
How fast is DSL really at my address?
The achievable data rate depends mainly on the length and quality of the copper line between the cabinet and the building. The binding figures are the three values in the product information sheet (Produktinformationsblatt): minimum, normally available and maximum data rate. An availability check using your full address tells you more than the advertised speed tier.
Can I use my own router with DSL?
Yes. Germany has free choice of terminal equipment (Routerfreiheit): you may run your own router on the line, and the provider must give you the access details you need. A rented router can still make sense if support and firmware updates are included – in that case, include the rental in the effective price.
