Before You Begin 13
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.
• SPID Number(s) - (For North America only) The SPID
(Service Profile Identifier) is a number used by a central office
switch for identification purposes. With the switch information,
see the previous table for the number of SPIDs you must enter.
You have now collected all of the necessary information about
your ISDN phone line. Make sure that these values are entered into
