External cellular recovery device

A cellular recovery device, comprising:

• a cellular modem to send a first plurality of cellular data packets to a network via a cellular communication system and to receive a second plurality of cellular data packets from the network via the cellular communication system;
• an Ethernet physical transceiver to:
• send a first plurality of Ethernet frames to a remote host via an Ethernet link between the remote host and the cellular recovery device;
• receive a second plurality of Ethernet frames from the remote host via the Ethernet link, the remote host including a router/switch;
• receive a first control message originating from the remote host for the cellular recovery device to process the transfer of data between the Ethernet physical transceiver and the cellular modem;
• receive a second control message from the remote host;
• and
• match a first matching pattern in the second control message to a first predetermined pattern;
• and
• a central processing unit to process the transfer of data between the Ethernet physical transceiver and the cellular modem;
• a memory to store therein a first base operating system image and a second base operating system image, wherein:
• the first base operating system image supports managing the transfer of data between the Ethernet physical transceiver and the cellular modem;
• and
• the second base operating system image supports recovery of a software failure in the remote host;
• and
• a programmable logic chip including a plurality of programmable hardware logic gates, the programmable logic chip being operative to:
• receive data from the Ethernet physical transceiver about the first matching pattern in the second control message;
• issue a command to perform at least one action in the cellular recovery device based on the first matching pattern of the second control message;
• initiate the central processing unit loading the first base operating system image or the second base operating system image as an operating system running on the central processing unit according to the first matching pattern of the second control message;
• initiate the central processing unit loading the second base operating system image as the operating system running on the central processing unit according to the first matching pattern in the second control message, wherein once recovery of the software failure in the remote host has been completed, the Ethernet physical transceiver is operative to:
• receive the first control message from the remote host;
• and match a second matching pattern in the first control message to a second predetermined pattern;
• receive data from the Ethernet physical transceiver about the second matching pattern in the first control message;
• and
• initiate the central processing unit resetting and loading the first base operating system image as the operating system running on the central processing unit according to the second matching pattern in the first control message.
