Using Direct Dial
Now that you have set up direct dial on your Niagara hosts, you must set up a few
more things in order to use it.
If your host will be making application-initiated calls (see the “User- versus
Application-initiated Connections” section on page 4-4), you must configure the
station address book so it knows where to find the host with which it wants to
communicate.
Making a user-initiated connection requires other configuration, and a manual
process to contact the remote host.
These topics discuss using direct dial on your hosts:
• Configuring the Station for Dial-out
• Making a User-initiated Connection from an Engineering PC
Configuring the Station for Dial-out
Note For most application-initiated connections, after you configure the station to find the
remote host, you do not need to do anything else—the station makes the connection
when it needs to. However, acknowledging alarms is different. The process is this:
1. Open the Alarm Console and acknowledge the alarm from the remote station.
2. Wait for the station to connect to the remote host.
3. Acknowledge the alarm a second time.
Failure to follow this process may result in you having to manually clear the alarm
acknowledgement database.
Configure the remote host in the station’s address book, as follows:
Procedure 4-10 Configuring the station for dial-out.
Step 1 Using the Java Desktop Environment (JDE), open the station running on the
JACE-NP.
Step 2 In the tree view, right-click the station name and choose Go > AddressBook.
Step 3 Click the Add Address button.
Step 4 In the New Address dialog box (Figure 4-23), fill out the following information:
• Station Name—The Niagara station name of the remote station. Must be
unique from other station entries in the AddressBook.
• User Name—An existing user account in the remote station. Specific security
rights for this user are not needed.
