P-2602H(W)(L)-DxA Series User's Guide 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. Table 2 ADSL Standards DATA RATE STANDARD ADSL ADSL2 ADSL2+ UPSTREAM 832 kbps 3.5Mbps 3.5Mbps DOWNSTREAM 8Mbps 12Mbps 24Mbps 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. 38 Chapter 1 Getting To Know the ZyXEL Device
