Each bit of this value set to '1' indicates a specific fault in the Media Gateway processor. Octets are numbered in the order in which they appear in the PDU. Bits are numbered from the most-significant leftmost bit in the octet (bit 0) to the least-significant rightmost bit (bit 7). Cajun numbering continues across octets, so that octet 1 bit 0 is called bit 8 in the Cajun scheme. That number is also shown below, with the octet value for each single bit set. Cajun Octet Octet bit# bit# value Meaning 0 0/0 0x80 Memory failure. 1 0/1 0x40 DHCP request failure. 2 0/2 0x20 Firmware download failure. 3 0/3 0x10 Software watchdog alert - MG processes restarting. 4 0/4 0x08 Internal Communications Controller expected but not present. 5 0/5 0x04 Internal Communications Controller automatic reset. 6 0/6 0x02 Media Gateway busy-out. 7 0/7 0x01 Configuration upload failure. 8 1/0 0x80 Primary controller not found. 9 1/1 0x40 No controller found. 10 1/2 0x20 Registration failure. 11 1/3 0x10 H.248 control link down. 12-13 1/4-5 Unused. 14 1/6 0x02 Maintenance test failure. 15 1/7 0x01 Maintenance test failure over threshold. 16 2/0 0x80 Configuration download failure. 17-23 2/0-7 Unused.
