The feature is designed for the scenario that requires only one WAN service in different applications. The Auto Detection page simply provides a checkbox allowing users to enable or disable the feature. Check the checkbox to display the following configuration options. 70 Enter the PPP username/password given by your service provider for PPP service detection. Select a LAN-as-WAN Ethernet port for auto-detect: Select the Ethernet Port that will be used as ETHWAN during auto-detection. 71 WAN services list for ATM mode: A maximum of 7 WAN services with corresponding PVC are required to be configured for ADSL ATM mode. The services will be detected in order. Users can modify the 7 pre-configured services and select disable to ignore any of those services to meet their own requirement and also reduce the detection cycle. WAN services list for PTM mode: A maximum of 7 WAN services with corresponding VLAN ID (-1 indicates no VLAN ID is required for the service) are required to be configured for ADSL/VDSL PTM mode and ETHWAN. The services will be detected in order. Users can modify the 7 pre-configured services and select disable to ignore any of the services to meet their own requirement and also reduce the detection cycle. 72 Click "Apply/Save" to activate the auto-detect function. Options for each WAN service: These options are selectable for each WAN service. Users can pre-configure both WAN services and other provided settings to meet their deployed requirements. Auto Detection status and Restart The Auto-detection status is used to display the real time status of the Auto-detection feature. The Restart button is used to detect all the WAN services that are either detected by the auto-detection feature or configured manually by users. The following window will pop up upon clicking the Restart button. Click the OK button to proceed. 73 Auto Detection notice Note: The following description concerning ETHWAN is for multiple LAN port devices only. 1) This feature will automatically detect one WAN service only. If customers require multiple WAN services, manual configuration is required. 2) If a physical ETHWAN port is detected, the Auto Detection for ETHWAN will be fixed on the physical ETHWAN port and cannot be configured for any LAN port; if the physical ETHWAN port is not detected, the Auto Detection for ETHWAN will be configured to the 4 th LAN port by default and allows it to be configured for any LAN port as well. 3) For cases in which both the DSL port and ETHWAN port are plugged in at the same time, the DSL WAN will ha ve priority over ETHWAN. For example, the ETHWAN port is plugged in with a WAN service detected automatically and then the DSL port is plugged in and linked up. The Auto Detection feature will clear the WAN service for ETHWAN and re-detect the WAN service for DSL port. 4) If none of the pre-configured services are detected, a Bridge service will be created. 74 6.2 Security To display this function, you must enable the firewall feature in WAN Setup. For detailed descriptions, with examples, please consult Appendix A - Firewall. 6.2.1 IP Filtering This screen sets filter rules that limit IP traffic (Outgoing/Incoming). Multiple filter rules can be set and each applies at least one limiting condition. For individual IP packets to pass the filter all conditions must be fulfilled.

Introduction In this document, we try to prove the safety of radiation harmfulness to the human body for our product. The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The Gain of the antenna used in this product is measured in a Fully Anechoic Chamber (FAC), and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis transmission formula is a far field assumption, the calculated result of that is an over-prediction for near field power density. We will take that as the worst case to specify the safety range. 2.
