If the modem configuration is incorrect, the Ping-to-Defaults procedure can be
used to restore default settings.
The technique is identical to that used for the Ping-of-Life procedure, except that
a different MAC address (01-90-D0-00-01-FF) is used.
Execute the following steps to reset the modem to its default settings:
1. Add the following to the arp cache:
arp -a <any IP address> 01-90-D0-00-01-FF
2. Reset the modem and wait for the self test to end.
3. Ping the IP address:
ping <any IP address>
