It will try these two alternatives indefinitely. If the dial backup attempt succeeds, the value of S-register S34 determines the interval of the dial backup connection before going back to check the leased line. ATS34=0 ATS34=n; (1 ≤ n ≤ 255; default: 30) The dial backup line continues to be used indefinitely. Reattempts leased line after n minutes. If the leased line has still not been recovered, the modem will continue to use the dial backup line. A semi-auto dial backup is selected if S44.2=1. In this mode, when making dial backup, the modem will display DIAL BACKUP? and wait for the user's confirmation. Only when the panel confirmation is pressed will the modem start the dial backup. This saves unnecessary dial backup connections when the line is not in use, e.g., non-business hours. Aborting from Leased-Line Operation If the leased line has not been connected, pressing any key on the front panel will abort the attempt to connect on the leased line. If dial backup is enabled, backup action will be taken. Pressing any key again will abort the backup action and revert to the IDLE SCREEN display. Disconnecting a Leased-Line Connection Disconnecting (manually) the leased line will force the LCD-model to switch to the IDLE SCREEN. Either going on-line manually or, if you have set the leased line as the power-on default, turning the power OFF and ON, will make the modem go to the leased line again. Pressing the DATA/VOICE switch on the non-LCD model will switch the modem on/off the connected leased line. 12-4
