Using H3Pingip - 3Com NBX 100 Administrator's Manual

Using H3PingIP

You can use the H3PingIP menu item to ping another device on the
network to test the telephone's connectivity and to check the packet
delay.
When using H3PingIP to test for connectivity, you must use the IP address
of a device that is connected to the NBX system NCP. You should not use
the NCP IP address. The NBX Business Telephone uses the IP Gateway and
subnet mask information programmed into it using the AB16 and AB17
buttons.
