Testing the ISDN Line
LoopTest tests the board’s ISDN line by establishing two
ISDN B channels in a loopback connection. One channel is set
up to accept incoming calls, and the other channel calls the first
channel. When the connection is established, the calling
channel sends data, which is checked when it arrives at the
receiving channel. At the end of the test, LoopTest stops the
communication. If an error occurs during testing, LoopTest
displays a warning and stops the communication at that point.
To check your ISDN line, do the following:
1. Before executing the LoopTest, to avoid incoming call
conflicts, disable the RAS Server, as follows:
a. From the Start menu, select Settings, and then
Control Panel. Then double-click the Services icon
to display the Services dialog box.
b. Select Remote Access Server from the list of
services, and click Stop.
A pop-up message informs you that the Virtual
Motion RAS Port Manager will also be stopped.
c. Click OK.
d. When the Services dialog box reappears, click
Close.
2. From the Start menu, select Programs, then
Interphase WAN Adapters, and then Loop Test.
