ADSL Standards
The ZyXEL Device is an ADSL router compatible with the ADSL/ADSL2/ADSL2+
standards. Maximum data rates attainable for each standard are shown in the next table.
" If your ZyXEL Device does not support Annex M, the maximum ADSL2/2+
upstream data rate is 1.2 Mbps. ZyXEL Devices which work over ISDN do not
support Annex M.
The standard your ISP supports determines the maximum upstream and downstream speeds
attainable. Actual speeds attained also depend on the distance from your ISP, line quality, etc.
