ADSL2+ is the latest version of ADSL for those who live in proximity to switches managed by an Internet Service Provider. The closer the user lives near the DSLAM, better will be the speed of transmission. VDSL stands for the Very-high-bit-rate Digital Subscriber Line.

What is VDSL Annex A?

For ADSL/VDSL routers, there are two types of WAN interface. While Annex A is for ADSL over POTS, Annex B is for ADSL over ISDN. We may tell the annex type by checking the type or the color of the DSL port.

What is ADSL Annex?

Annex M is an ADSL2+ standard that increases your upstream data rate beyond the limits of standard ADSL2+. Learn how to enable Annex M, what factors affect speeds, and more in this FAQ.

Is UK Annex A or B?

Re: Annex A or B If you’re looking at DSL standard in the UK (ADSL/FTTC), it’s Annex A (POTS).

Should I enable Annex M?

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? An Annex M compatible modem/router (you will need to enable Annex M mode).

What is Annex B?

Definition: Annex I and Annex B Countries/Parties are the signatory nations to the Kyoto Protocol that are subject to caps on their emissions of GHGs and committed to reduction targets–countries with developed economies.

What is line attenuation?

Line attenuation (loss) is a measure of how much the signal has degraded between the DSLAM and the modem. This is largely a function of the distance from the exchange. The lower the dB, the better for this measurement.

What is ADSL Annex M?

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.

What is the difference between ADSL2 and ADSL 2+?

The difference between ADSL2 and ADSL2+ is that ADSL2+ uses twice as much bandwidth long the existing copper wires as ADSL2 does. ADSL2 uses exactly the same bandwidth as ADSL. Local Loop Unbundling (LLU) services use ADSL2+ technology and they can offer faster speeds in many exchanges.

What are the characteristics of ADSL?

The main characteristic of an ADSL connection is that it is faster to download, or receive data, than it is to upload, or send, the information. Depending on your distance from the telephone exchange (or ISP’s central office), you may notice significant variations in the signal strength.

Does Openreach sell ADSL broadband?

Although Openreach used to be owned by BT, it does not mean that BT is the only provider who can sell ADSL packages. Other providers can also offer this broadband package through a process known as Local Loop Unbundling (LLU).

What is an uncapped ADSL connection?

An uncapped ADSL connection essentially allows the user to have unlimited internet usage for a monthly fee. This solution is ideal and cost-effective for small or satellite offices, but we would always recommend that a voice assured variant is used to guarantee voice channels for VOIP.
