[. . . ] RIP: RIP v1, RIP v2, RIP v1+v2 and RIP v2 Multicast. The size of the largest datagram (excluding media-specific headers) an IP attempts to send through the interface. Apply RFC 1483 Bridged Connections Description: A user-definable name for this connection. VPI/VCI: Enter the information provided by your ISP. Encapsulation method: Select the encapsulation format, this is provided by your ISP. 44 4. 3. 2. 2 DNS A Domain Name System (DNS) contains a mapping table for domain name and IP addresses. On the Internet, every host has a unique and user-friendly name (domain name) such as www. billion. com and an IP address. An IP address is a 32-bit number in the form of xxx. xxx. xxx. xxx, for example 192. 168. 1. 254. You can think of an IP address as a telephone number for devices on the Internet, and the DNS allows you to find the telephone number for any particular domain name. Since an IP Address is hard to remember, the DNS converts the friendly name into its equivalent IP Address. You can obtain a Domain Name System (DNS) IP address automatically if your ISP has provided it when you logon. Usually when you choose PPPoE or PPPoA as your WAN - ISP protocol, the ISP provides the DNS IP address automatically. You may leave the configuration field blank. Alternatively, your ISP may provide you with an IP address of their DNS. If this is the case, you must enter the DNS IP address. If you choose one of the other protocols, RFC1483 Routed or Bridged, check with your ISP, as it may provide you with an IP address for their DNS server. You must enter the DNS IP address if you set the DNS Server address on your PC to the LAN IP address of this router. 45 4. 3. 2. 3 ADSL ADSL Mode: There are four modes "Open Annex Type and Follow DSLAM's Setting", "Annex A Only", "Annex L Only" and "Annex M Only" that user can select for this connection. Modulator: There are four modes "AUTO", "ADSL multimode", "ADSL2"and"ADSL2+" that user can select for this connection. DSP Firmware Version: DSP code version DMT Status: DMT Status Operational Mode: To show the state when user select "AUTO" on connect mode. Annex Type: To show the router's type, e. g. Annex A, Annex B Upstream: Upstream rate Downstream: Downstream rate 46 4. 3. 3 System There are six items within the System section: Time Zone, Remote Access, Firmware Upgrade, Backup/Restore, Restart and User Management. 4. 3. 3. 1 Time Zone The router does not have a real time clock on board; instead, it uses the Simple Network Time Protocol (SNTP) to get the current time from an SNTP server outside your network. Choose your local time zone, click Enable and click the Apply button. After a successful connection to the Internet, the router retrieves the correct local time from the SNTP server you have specified.
