Installing the Internal I-modem 4-5
Figure 4.2 Default Jumper Settings
In addition to the shunt shown in Figure 4.2, the I-modem is shipped with
two additional shunts. These shunts do not affect the configuration of
your I-modem because they are attached to only one post; change the
positions of these shunts only if you need to change hardware settings.
Notes:
•
The S/T version has an additional set of jumpers.
•
For most configurations, default settings will work. However, if your
environment has multiple ISDN devices or you are using an NT-1, see
the I-modem Command Reference manual.
Windows 95 Users
If you are using Window 95, you should not need to change the Plug and
Play jumper settings, because Windows 95 automatically detects and
configures your Courier.
Other IBM-PC Compatible Operating Systems
If you are using an IBM-PC compatible operating system, you may need
to change the jumper settings to a COM port or IRQ setting that is not
already used by your system.
For information about setting jumpers for different COM ports and IRQ
settings, see Chapter 12, Configuring Your Courier With DIP Switches and
Jumpers.
