What is Bonded ADSL?
Bonded ADSL is a broadband technology that combines multiple ADSL lines into a single, faster, and more reliable internet connection, because instead of relying on just one slow ADSL connection, Bonded ADSL merges two or more lines, effectively doubling or tripling the available bandwidth.
💡 Who is it for?
✔️ Businesses in rural or underserved areas without access to fibre broadband.
✔️ Companies requiring higher bandwidth for cloud applications, VoIP, or video conferencing.
✔️ SMEs looking for a cost-effective alternative to leased lines.
How Does Bo nded ADSL Work?
Bonded ADSL works by aggregating two or more ADSL connections into one virtual network, using specialised bonding equipment.
🔍 Here’s a step by step on how it works:
Multiple ADSL lines are installed at the business premises.
A bonding router combines the individual connections into one high-speed link.
The bandwidth from each ADSL line is merged, providing faster speeds than a single connection.
If one line fails, the others continue operating, ensuring minimal downtime.
