Prestige 324 User's Guide Table 6-9 Dial Backup Setup LABEL DESCRIPTION Configure Budget Select this check box to have the dial backup connection on during the time that you select. Allocated Budget Type the amount of time (in minutes) that the dial backup connection can be used during the time configured in the Period field. Set an amount that is less than the time period configured in the Period field. Period Type the time period (in hours) for how often the budget should be reset. For example, to allow calls to this remote node for a maximum of 10 minutes every hour, set the Allocated Budget to 10 (minutes) and the Period to 1 (hour). Idle Timeout Type the number of seconds of idle time (when there is no traffic from the Prestige to the remote node) for the Prestige to wait before it automatically disconnects the dial backup connection. This option applies only when the Prestige initiates the call. The dial backup connection never times out if you set this field to "0" (it is the same as selecting Always On). Apply Click Apply to save your changes back to the Prestige. Reset Click Reset to begin configuring this screen afresh. 6.11 Advanced Modem Setup 6.11.1 AT Command Strings For regular telephone lines, the default "Dial" string tells the modem that the line uses tone dialing. "ATDT" is the command for a switch that requires tone dialing. If your switch requires pulse dialing, change the string to "ATDP". For ISDN lines, there are many more protocols and operational modes. Please consult the documentation of your TA. You may need additional commands in both "Dial" and "Init" strings. 6.11.2 DTR Signal The majority of WAN devices default to hanging up the current call when the DTR (Data Terminal Ready) signal is dropped by the DTE. When the "Drop DTR When Hang Up" check box is selected, the Prestige uses this hardware signal to force the WAN device to hang up, in addition to issuing the drop command "ATH". WAN Screens 6-21
