The ZyXEL Device is an ADSL router compatible with the ADSL/ADSL2/ADSL2+
standards. It allows super-fast, secure Internet access over the analog (POTS) or digital
(ISDN) telephone line (depending on your model). 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.
Models ending in "1", for example P-660RU-T1, denote a device that works over the analog
telephone system, POTS (Plain Old Telephone Service). Models ending in "3" denote a device
that works over ISDN (Integrated Synchronous Digital System). Models ending in "7" denote
a device that works over T-ISDN (U-R2).
