Testing the TCP/IP software

Test the TCP/IP software if subscribers are experiencing difficulties with:

• Voice mail subscribers not being able to send or receive messages to or from remote voice mail systems via Message Networking.
• Digital networking using TCP/IP.

To test the TCP/IP software:

1. Start at the Administration menu, and select Diagnostics > TCP/IP Diagnostics > Send & Receive Test Packets
   The system displays the Send and Receive Test Packets To & From page. For information about the fields on this page, click Help.
2. Type the IP address of the system for which you want to run the test in the IP Address field.
3. Click Save to run the test.
   When the test is finished, the system displays the Send and Receive Test Packets To & From results page. This window shows the results of sending 10 test packets from the Message Networking system to itself.
4. Examine the packet loss field in the Ping Statistics displayed on the Test Packets Results page. The value for this field is either 0% or 100%, as described below.
• If 0% packet loss is reported, the test is successful. This result indicates that the problem is not with the Message Networking system's TCP/IP software; however, the problem could be with the LAN card or the network. To further isolate the problem, test the connection between the Message Networking system and a subscriber's PC.
• If 100% packet loss is reported, the test failed. Check with your LAN administrator to ensure that you used the correct IP address for the system. This result could indicate a problem with the Message Networking system's TCP/IP software. Reboot the system, and repeat this test. If the test still fails, contact your remote services center.
