DSL (Digital Subscriber Line) delivers internet through traditional copper telephone lines. It was one of the first forms of broadband and is still used by some businesses today—especially in areas where newer options aren’t yet available.
vDSL (Very-high-bit-rate DSL) is an upgraded version of DSL that offers faster speeds over short distances. While both are being phased out in many areas, they can still be a useful option in the right scenario.
How It Works for Businesses
DSL uses copper phone lines to deliver data. It’s available anywhere a phone line exists, though the distance between your business and the service provider’s central office impacts your speed.
vDSL uses the same copper lines but with improved technology. It typically delivers higher speeds and is more reliable than basic DSL, especially in buildings with newer wiring and closer proximity to network infrastructure.
Typical Speeds and Performance
Standard DSL typically delivers 10 to 30 Mbps download and 1 to 10 Mbps upload. vDSL can reach speeds of up to 100 Mbps down and 30 Mbps up, depending on line quality and distance.
Latency is moderate and generally sufficient for basic business tasks like email, file sharing, and cloud access. Video calls and VoIP may work, but performance can vary.
Pros and Cons
Why Businesses Choose This Option:
- Very low monthly costs
- Available in older buildings and legacy infrastructure
- Quick installation with minimal setup
Things to Consider:
- Speed and reliability depend heavily on distance and line condition
- Lower performance than modern options like fibre or cable
- Being phased out in many areas as networks are upgraded
When It Makes Sense
DSL and vDSL may still be viable in areas where no other broadband options are available. They’re also occasionally used as backup connections or in legacy setups where equipment is already in place.
For businesses with very basic connectivity needs, DSL offers a low-cost way to get online—at least until better service becomes available.
