DSL enhancements

* A look at ADSL2 and ADSL2+

For a while it seemed as though a new category of high-speed DSL came out every week. Thankfully things have settled down and most DLS technology changes are in the form of enhancements to existing standards.

Such is the case with ADSL2 and ADSL2+.

Specifically ADSL2 increases downstream data rates to more than 12M bit/sec, and extends reach by approximately 600 feet, says our Technology Update author ( ADSL2+ (G.992.5), more than doubles the downstream data rate of ADSL to 20M bit/sec. The first flavors of ADSL delivered 6M bit/sec of voice and high-speed data from the network to the end user. Another thing to remember is that ADSL is the most predominant for business use.

The good news is that ADSL2 will be interoperable with existing ADSL deployments so there won’t be a need for forklift upgrades in the service provider realm.

Not only that but while these new standards will increase range, reach and throughput, they will also offer improved diagnostics.
