ZyXEL Communications Prestige 28641 User Manual page 27

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
modem, A/B adapter, or select Ignore if you don't want to utilize
this option.
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 your
worksheet before you continue to the next section. For DSS1 and
1TR6 ISDN, refer to Chapter 3.
