3.2.2.2 Telesyn Implementation
In most cases, the initial configuration of the Telesyn will have at least one ADSL16 or ADSL8S card. These
cards can be either ANNEX A or ANNEX B versions.
The ADSL2+ mode is a new, evolving specification for ADSL (G.992) that enables higher downstream band-
width, based on ITU G.992.5. ADSL8S and ADSL16 Annex A hardware currently in the field will support the
ADSL2+ mode using the new software.

Following are the MAP and SM features that ADSL supports. See the Telesyn User Guide for information on
