ADSL and ADSL2+ Annex M

BtL Internet Icon

Asymmetric Digital Subscriber Line (ADSL) is a technology similar to DSL. With ADSL, information is downloaded more rapidly than it is uploaded. The speed of ADSL connections depends on how far your premises are from the telephone exchange and the type of ADSL connection required. Maximum download speeds vary from 2Mbps to 24Mbps. Maximum upload speeds generally range up to 1.5Mbps. Different types of ADSL connections include ADSL2+, IP Stream Max, and ADSL2+ Annex M as described below.

ADSL2+ Annex M business broadband is designed for companies that require a higher upstream bandwidth compared to ADSL 2+. ADSL2+ Annex M reduces the normal download speed of an ADSL connection in order to provide up to double the upload speed compared to ADSL 2+. ADSL2+ Annex M will provide the best possible speed that your telephone line will support, up to a maximum downstream of 16Mb and upstream of 2.5Mb by trading some of the download speed.
