Collecting ISDN Phone Line Information
Once your ISDN line is installed by the telephone company, you need to use the following
information to complete the worksheet and configure your Prestige. Much of this information is
provided by your telephone company upon intallation of the ISDN line.

Switch Type - This is the type of switch used by your telephone company. Check with your
telephone company and choose the appropriate option on the worksheet.
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 Prestige will use both B
channels to communicate. If your Prestige is sharing the ISDN line with other devices, then
configure B Channel to Switch/Unused.
Telephone Number(s) - Record on the worksheet the telephone number(s) given to you by your
telephone company. Some switch types only have one telephone number. These telephone
numbers should be in a standard digit format (for example, 5551212). Please note that these fields
only accept digits, so ‘-’ and spaces are not allowed.
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.
Supplemental Service Activation Keys Sometimes called ‘buttons,’ most of the supplemental
services supported by the Prestige require that an activation key be set before a feature can be
used.
You have now collected all of the necessary information about your ISDN telephone line. Make
sure that these values are entered into your ‘Setup Information Worksheet’ before you continue to
the next section.
