This value will correspond to the amount of idle time (no Internet activity) that will pass before the Gateway automatically ends your PPTP session. 7IP settings must be used when establishing a PPTP connection. Fill in the Initial IP Address and the Initial Subnet Mask fields if your ISP has provided you with these settings. Alternatively, if the PPTP server is located in your DSL modem, click Suggest to select an IP address on the same subnet as the PPTP server. FirewallOn the main frame of the Firewall setup screen is a menu with five tabs: Virtual Servers, Special Applications, PCs Privileges, URL Filter, and Security. Virtual ServersSelecting the Firewall option on the main menu displays the Virtual Servers setup screen. (Figure 45 ) Virtual DMZ Figure 45 Virtual Servers Screen 64CHAPTER 5: GATEWAY CONFIGURATION DMZ (De-Militarized Zone) Host is a computer without the protection of the firewall. This feature allows a single computer to be exposed to unrestricted 2-way communication from outside of your network. This feature should be used only if the Virtual Server or Special Applications options do not provide the level of access needed for certain applications. To configure one of your computers as a DMZ host, enter the last digit(s) of the IP address of the computer in the IP Address of DMZ Host text box, and then click Apply. Virtual Server Activating and configuring a virtual server allows one or more of the computers on your network to function as a public server. For example, one of your computers could be configured as an FTP server, allowing others outside of your office network to download files of your choosing. Or, if you have created a Web site, you can configure one of your computers as a Web server, so that others can view your Web site. To configure a virtual server: 1Click New on the right side of the screen to open the Virtual Server Settings dialogue box. (Figure 46 ) 2Enter the last digit(s) of the IP address of the computer in the Server IP Address text box. 3Select the Service from the pull-down list.

(Figure 47 ) Figure 47 Custom Setup Screen 4Click Add to save the settings. The port numbers are specified using a comma-separated list, with hyphens to denote port number ranges. So for example, entering 2, 3, 5-7 would cause ports 2, 3, 5, 6, and 7 to be activated. Special Applications Figure 48 Special Applications Screen Select Special Applications tab to display Authorized Application setup screen. (Figure 48 ) Some software applications require special or multiple connections to the Internet and these would normally be blocked by the firewall. For example Internet Telephony or Video conferences require multiple connections. So that these special applications can work properly and are not blocked, the firewall needs to be told about them. In each instance there will be a 66CHAPTER 5: GATEWAY CONFIGURATION trigger port and incoming port(s), where traffic on the trigger port tells the firewall to open the incoming ports. Each defined Special Application only supports a single computer user, and up to 10 Special Applications can be defined. Any incoming ports opened by a Special Application trigger will be closed after five minutes of inactivity. To configure special applications: 1Click New. 2Select the applications from the pull-down list. (Figure 49 ) …

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 October 7, 2003 RE: Accton Technology Corporation FCC ID: HED3CRWE554G72 After a review of the submitted information, I have a few comments on the above referenced Application. 1) Please provide an additional photograph underneath the shield/copper tape located on the bottom of the board. 2) The users manual page 123 mentions that the device must utilize shielded interface cables. However, page 101 states the device may uses shielded or unshielded cables. Additionally, the testing configuration given in the test report page 9 does not clearly label the UTP cable as shielded or unshielded. Given the prevalence of unshielded UTP, please confirm if the device was tested with a shielded or unshielded UTP cable. If the device was tested and meets the requirements with an unshielded UTP cable, it would be best to remove the phrase "(for example, use only shielded interface cables when connecting to computer or peripheral devices)" from the manual. However if a shielded cable is required, please have the manufacturer confirm that the unit ships with a shielded cable and remove the reference to unshielded cables on page 79. 3) The calculation on note 1 on page 53 of the test report appears incorrect. 103.7 - 57.53 = 46.17. Please correct. Timothy R. Johnson Examining Engineer mailto: [email protected] The items indicated above must be submitted before processing can continue on the above referenced application.

ISSUED BY: Advance Data Technology Corporation LAB LOCATION: No. 81-1, Lu Liao Keng, 9 Ling, Wu Lung Tsuen, Chiung Lin Hsiang, Hsin Chu Hsien, Taiwan, R.O.C. Lab Code: 200376-0 FCC ID: HED3CRWE554G72 Report No.: RF920612H04 ADT No. 920612H04 2 RF Exposure Measurement 1. 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) calibrated for antenna measurement in ADT, 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. RF Exposure Limit According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm 2 ) Average Time (minutes) (A)Limits For Occupational / Control Exposures 300-1500......F/3006 1500-100,000......56 (B)Limits For General Population / Uncontrolled Exposure 300-1500......F/15006 1500-100,000......1.030 F = Frequency in MHz FCC ID: HED3CRWE554G72 Report No.: RF920612H04 ADT No. 920612H04 3 3. Friis Formula Friis transmission formula : Pd = (Pout*G) / (4*pi*r 2 ) where Pd = power density in mW/cm 2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in cm Pd is the limit of MPE, 1 mW/cm 2 . If we know the maximum Gain of the antenna and the total power input to the antenna, through the calculation, we will know the MPE value at distance 20cm. Ref. : David K. Cheng, Field and Wave Electromagnetics, Second Edition, Page 640, Eq. (11-133). 4. EUT Operating condition The software provided by Manufacturer enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. 5. Classification This device is not fixed inside the host equipment, it is connected with host through wire. So it is easy to be re-located in the place where at least 20 cm far away from the body of the user. Warning statement to the user for keeping at least 20cm or more separation distance with the antenna should be included in users manual. So, this device is classified as Mobile Device.
