38 Chapter 1 Getting To Know the ZyXEL Device
Models with “3” as the next to the last character (like the P-2602HWL-D3A) denote a device
that works over ISDN (Integrated Services Digital Network). Models with “1” or “7” as the
next to the last character (like the P-2602HWL-D1A or the P-2602HWL-D7A) 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 web browser-based Graphical User Interface (GUI) provides easy management.
Note: All screens displayed in this user’s guide are from the P-2602HWL-D1 model.
1.2 Features
The following sections introduce your device’s key features.
Built-in Switch
The four 10/100 Mbps auto-negotiating Ethernet ports allow the ZyXEL Device to detect the
speed of incoming transmissions and adjust appropriately without manual intervention. It
allows data transfer of either 10 Mbps or 100 Mbps in either half-duplex or full-duplex mode
depending on your Ethernet network. The ports are also auto-crossover (MDI/MDI-X)
meaning they automatically adjust to either a crossover or straight-through Ethernet cable.
High Speed Internet Access
The ZyXEL Device is ideal for high-speed Internet browsing and making LAN-to-LAN
connections to remote networks. The ZyXEL Device is compatible with the ADSL/ADSL2/
ADSL2+ standards. Maximum data rates attainable for each standard are shown in the next
table.
Note: 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.
