ADSL2 Bonding


ADSL2+ is by far the most popular broadband technology deployed in Australia today. It works extremely well for many, many users at a very affordable price point.

Some facts about ADSL2+

The ‘A’ stands for ‘Asymmetric’ which means download speeds are faster than upload speeds

It’s a copper-based broadband technology, so that means performance will be limited by distance from the exchange

Most ADSL2+ services are geared towards home or small business users, so will usually be contended, further limiting performance

ADSL2+ upload is very easy to ‘max out’, and when it is fully utilised, overall latency skyrockets and your download speeds and general 'usability' will be severely impacted

We go into these issues in detail in our Technologies and Networks section.


ADSL2+ falls just short for some users Many business customers are finding that as their usage grows, and their business operations become more dependent on their broadband, they outgrow the capability of their ADSL2+ connection. The symptoms could be slow download or upload, dropouts or complaints from staff and customers.

This growth hasn’t happened over night – it’s been a gradual process that will likely continue. Businesses in these circumstances probably don’t want to make the jump to a full-blown corporate grade solution with the associated cost. They just want ADSL2+ that ‘works a bit better’ than their current connection.

The current provider can’t give them more because there’s nothing they can do about how far they are from the exchange.
The current provider could give a better grade, or uncontended, service at a higher price, but what’s the point if speed is ultimately limited by distance from the exchange?

Most ADSL2+ services (and ADSL1 services) would work much better if they had a bit more upload speed and better still if usage was properly managed and they were also not contended with other users.


Bonding ADSL2+ True bonding means that any single user connection, whether download or upload, can take advantage of the combined speeds of the services being bonded.

Load balancing differs from true bonding in that the first user's connection is sent across one ADSL and the second user's connection is sent across the second ADSL, so that each user only ever experiences a maximum speed equal to that of a single ADSL service.

Businesses can implement load balancing themselves with a dual-WAN router, but for true bonding, the service provider must also be involved.

A bonded ADSL2 service from Pacific Wireless bonds multiple ADSL services at the carrier level and the customer is simply presented with a single port which carries significantly improved performance.



A Pacific Wireless bonded ADSL2 service has the following benefits:

  • Speeds at the sum of the combined rates of the services (less a small overhead)
  • We provide the ADSL2 services and modems, so they are high-grade and uncontended
  • We implement traffic management techniques to ensure latency does not skyrocket when upload is maxed-out

By combining these three techniques, customers can expect a 4-fold improvement in overall user experience with a bonded ADSL2 service when compared with a single ADSL2.
