An SDSL (Symmetric Digital Subscriber Line) gives businesses a more efficient and reliable way of transferring data. It is basically a dedicated line that offers high speeds and a completely secure connection to the internet. In a nutshell, SDSL is a cost-effective way for companies to stay connected.

What Does SDSL Offer?

An increasing number of organisations are choosing business SDSL connections. With a consistent upload and download rate, this dedicated line ensures businesses maintain a secure and stable online connection come what may. Business SDSL can offer speeds of up to 32 Mbps with a 1:1 contention ratio - ensuring that online speeds will not be disrupted at peak times. What's more, all our symmetric digital subscriber lines are backed by a 99.9 per cent SLA or Service Level Agreement. Companies across the UK choose SDSL because they recognise that consistent data flow is a key requirement in the modern business world.

Secure SDSL

A business SDSL connection offers increased security - having a dedicated line preserves the integrity of information passed in and out of a company, ensuring data remains private. This type of business broadband solution can also be used to complement a virtual private network, ensuring cost-effective and secure data transfer.

SDSL For Business

It is important to point out that we do not mix commercial traffic with consumer traffic so your company will not suffer a severe slump in performance when it matters most. We understand that data sent over a business SDSL needs to arrive quickly and safely.

Why Use SDSL?

  • Lower cost option that MPLS or leased line, but better than ADSL
  • SDSL connects your business sites together, cost-effectively at high speed
  • SDSL gives your teleworkers a fast and efficient connection to your servers
  • Host your own websites or email servers

As an alternative to SDSL, Telefonix Voice & Data can also provide asymmetric bandwidth, which offers greater bandwidth out to the Internet, rather than from the Internet. The service also gets you uncontended dedicated bandwidth that no other business will share, with a 100% availability target backed by a Service Level Agreement and 24/7, 365/365. For further details, see leased lines.
