Telephone Troubleshooting 359
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.
H3PingIP shows the following information:
Port — The UDP Destination Port
Tx — The number of packets transmitted
Rx — The number of packets received
mS — The delay time, in milliseconds
If you ping a device on a subnetwork different than the one on which the
telephone is located, the delay time is greater.
