Configuring the 3C882 ISDN Modem for a PC 3-10
One Telephone Number per Analog Device. If you have
two telephone numbers and two analog devices, you may
want one telephone number associated exclusively with just
an analog telephone and the other telephone number
associated with just a fax machine.
In this example, shown in Figure 3-10, calls to 908 555 1212
will only be routed to the telephone.
Figure 3-10 Configuration for One Telephone Number per Device
One Telephone Number and Two Analog Devices. If you
have only one telephone number for your ISDN line and two
analog devices, check the Phone Port 1 and Phone Port 2
boxes located in the Number 1 group box, as shown in
Figure 3-11. Calls to that telephone number will ring both
devices allowing you to answer a call using either one.
Note that while you are using the fax machine, for example,
you cannot use the telephone to place or receive calls
because your ISDN line has only one telephone number.
