What is Annex M?
Annex M is an ADSL2+ standard that increases your upstream data rate beyond the limits of standard ADSL2+.
Most Australian ADSL2+ uses the Annex A standard, with a theoretical upstream data rate of 1.4 Mbps. Annex M increases the maximum data rate—up to 3 Mbps. Internode have recorded real-world speeds of up to 2.5 Mbps, but typical upstream speeds are around 1.6 to 2.2 Mbps.
Any increase in upstream speeds will result in a matching decrease in downstream speed—usually at a 1:1 ratio. Just like standard ADSL, your speeds also depend on the quality of your wiring, and the length and condition of your phone line.
Why Annex M?
Faster uploads means you can send files to clients and other offices faster. Better upload speeds also improve videoconferencing, VOIP quality and help staff working from home.
Annex M allows dramatic increases in upstream data speeds. Real world speeds are usually around 1.6 to 2.2 Mbps—sometimes even twice as fast as standard ADSL2+!
What do you need?
- Annex M compatible connection (Request a service qualification here)
- An Annex M compatible modem/router (you will need to enable Annex M mode).
