This chapter describes the key features and applications of your ZyXEL device .
1.1 Introducing the P-660HW-D
The ZyXEL device is an ADSL2+ gateway that allows super-fast, secure Internet access over
analog (POTS) or digital (ISDN) telephone lines (depending on your model).
In the ZyXEL device product name, “H” denotes an integrated 4-port switch (hub) and “W”
denotes an included wireless LAN card that provides wireless connectivity.
Models ending in “1”, for example P-660HW-D1, 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 Services Digital Network). Models ending in “7” denote a
device that works over T-ISDN (UR-2).
Note: Only use firmware for your ZyXEL device’s specific model. Refer to the label on
the bottom of your ZyXEL device.
The DSL RJ-11 (ADSL over POTS models) or RJ-45 (ADSL over ISDN models) connects to
your ADSL-enabled telephone line. The ZyXEL device is compatible with the ADSL/ADSL2/
ADSL2+ standards. Maximum data rates attainable by the ZyXEL device for each standard
are shown in the next table.
Note: 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.
