America, select your ISDN switch type. For DSS1 and 1TR6, verify this field to make sure that you have the proper firmware loaded.

∙B Channel Usage - Determine which connection is appropriate for your B channel and check the corresponding option on the worksheet.

If your Prestige is the only device using the ISDN line, then configure B Channel Usage to Switch/Switch so that your device will use both B channels to communicate. If your Prestige is sharing the ISDN line with other devices, then configure B Channel Usage to Switch/Unused.

∙Telephone Number(s) - Record on the worksheet the telephone number(s) given to you by your ISDN provider. Some switch types only have one telephone number. These phone numbers should be in a standard digit format (for example, 5551212). Note that these fields will only accept digits, so - and spaces will not be accepted.

∙Analog Call - Check the appropriate Analog Call option on the worksheet for each telephone number. This information is later used to configure the Prestige in routing an incoming analog call. Set to Phone1 or Phone2 if you wish to route the incoming analog call for this telephone number to PHONE port number 1 or 2.
