The password can be up to 20 alphanumeric characters long. · Enter the Tel No (telephone number) that the Internet module dials for Internet access. · Enter the Backup No (telephone number). This allows the Internet module to dial an alternative telephone number for Internet access in the event that the first number is unreachable. If no number is entered here then only the first number is used. If the first attempt to dial the ISP is unsuccessful, the number is redialed a number of times which can be set within the range 1 ­ 10. The number of retries applies first to the main telephone number and then to the backup telephone number, if it is used. · Max calls/day sets a threshold on the maximum number of ISDN calls allowed per day. When this threshold is exceeded, the profile is disabled and must be manually reset using the pop up RESET button on the screen. If Max calls/day is set to zero, then there is no restriction on the number of calls that can be made in any day. · Max call duration sets the threshold on the maximum duration in hours during any day that calls can be made. · IP address is normally left at the default setting, which is 0. 0. 0. 0, which allows the address to be assigned by the ISP at connection set-up. In certain circumstances, the ISP may assign a static IP address that is entered here. · NAT enabled ­ yes is the default setting. This allows all PCs connected to the local LAN to concurrently access the Internet. The profile must be enabled to allow users to use the ISDN for Internet access. · Click on the Save button · Click on the Send button · Press the RESET button on the screen for the changes to take effect. · Timebands takes you into the Timebands menu, which allows you to restrict Internet access to certain times of the day.
