1.1 Introducing the ZyXEL Device
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.
Model names ending in “1”, for example P-660HW-T1, denote a device that works over the

denote a device that works over ISDN (Integrated Services Digital Network).
The DSL RJ-11 (ADSL over POTS models) or RJ-45 (ADSL over ISDN models) connects to
your ADSL-enabled telephone line.
Note: Only use firmware for your ZyXEL Device’s specific model. Refer to the label on
