SDSL – An Overview

An SDSL (Symmetric Digital Subscriber Line) is a symmetrical Internet connection with identical upstream and downstream.

The contrast to normal DSL lines offered to private customers is in the symmetry. Bandwidth for private customers only pertains to the downstream; the upstream is generally significantly lower. This is because private customers generally only transfer a small amount of date to the network.

An SDSL connection is usually used as a pure Internet connection by smaller companies or as a backup for an already existing dedicated line. It could also be used to locally network smaller branch offices with the central MPLS or VPN network.

Depending on the location, SDSL connections are offered from 2 Mbit/s up to 40 Mbit/s. In contrast to leased line, these lines are primarily copper-based, which, in comparison to fiber glass, does not guarantee the same level of reliability.

It is important to understand that with an SDSL connection, the bandwidths are not guaranteed. If you require guaranteed bandwidths for your internet access, you should consider a dedicated line.

In addition to the Deutsche Telekom with its product, DSL Business symmetric, a number of other providers have established themselves on the market, including QSC with QDSL Max or Vodafone with  Business DSL Profi. You can find a complete list in the Providers section. A more precise comparison is worth it, not only because of the differences in costs, but because of the SLAs and additional options.

Before you get an SDSL connection, you should be sure it fulfills your requirements. We will gladly assist you and and consult with you, with no commitment, on whether it is the right solution for your company.

leased line or a wireless local loop (WLL) connection might be alternative options.

Features

Depending on the line provider, the features and additional options may vary. It is important to pay close attention. The following features are generally offered:

  • QoS (Quality of Service) with two or more service classes for prioritizing, e.g. voice
  • SLAs (Service Level Agreements) offer different guaranteed availabilities and repair times
  • IP monitor
  • Managed router with customized configuration
  • Statistical IP range

Costs for an SDSL connection

It is difficult to offer a clear cost structure in this area. The prices are dependent upon a number of factors:

  • Technology used (SHDSL.ATM or SHDSL.bis)
  • Provider selection
  • Desired bandwidth
  • Rate model: flat rate or volume rate
  • Desired additional options (e.g. IP monitor)

For a 10 Mbit/s SDSL connection, the average costs are estimated at approx. € 200.00.
