Configuring Direct Dial on the JACE-NP
Configuring direct dial on the JACE-NP consists of three major steps:
• Installing and Configuring Modems
• Configuring the RAS Software
• Granting Dial-in Permissions
Installing and Configuring Modems
You can purchase an internal modem when ordering a JACE-NP, or you can attach
an external one to either of the RS-232 serial ports. When you order an internal
modem with a JACE-NP you must also buy the upgrade to the full version of NT as
the embedded version will not work with the internal modem.
Caution Do not add your own internal modem to a JACE-NP. This invalidates your
warranty.
Supported
Modems
When shipped with an internal modem, a driver for that modem is configured in the
NT OS for COM3. When no internal modem is purchased, a driver for the U.S.
Robotics 56K Fax External modem is configured on COM1.
If you choose not to use our supplied internal modem, or the pre-configured default,
you can use any modem that provides a driver for Windows NT 4.0.
Installing an
External Modem
To install the modem, connect a standard serial cable to the DB-9 male serial port of
your choosing on the JACE (either COM1 or COM2). Attach the other end of the
serial cable to the DB-25 male connector on the modem.
Note The JACE-NP does not support USB-connected modems.
Installing the
Modem Driver
Many modem drivers are provided with the Windows NT 4.0 OS. However, if you
are using a modem driver that is not available in the OS, you must load the driver.
Since the JACE-NP has no floppy disk to load the driver, your JACE-NP must be
attached to a LAN. The LAN provides the access method to the driver file.
Use the following steps to add a modem driver to a JACE-NP.
Procedure 4-4 Installing a modem driver on the JACE-NP.
Step 1 If you are installing the driver on a JACE-NP with Embedded NT, access the
Windows NT desktop with NetMeeting (see “NetMeeting,” page 2-2). Otherwise,
attach a keyboard, monitor, and mouse to access the desktop.
