Most Asked question:
What is the differance between Annex A and Annex B?
ADSL can be put on the telephoneline by either the Annex A or the Annex B method. In most countries Annex A is applied on the analog telephonelines. On a ISDN line only ADSL Annex B can be used. The reason for this is that the bandwidth used by Annex A overlaps with the bandwidth used by the ISDN line
