What follows is a short explanation of the more common error and warning messages you are likely to see in the Description field while debugging the connection between the P-971M and the CMTS. Refer to DOCSIS 2.0 for additional information on SNMP status messages for cable modems. Error and warning messages are shown in boldface type.

DHCP Warning - Non-critical field invalid in response (Critical).

The P-971M has received a response to its DHCP request from the cable operator’s CMTS, but the responding DHCP server did not include all of the required fields in the message. This message might also appear if one of the required fields in the DHCP message contains an invalid value. Reconfigure the DHCP server so that it sends all of the required fields.

DHCP ERROR - The DHCP response does not contain all of the required fields or the PS (Portal Services) is unable to determine provisioning mode.

The P-971M has received a response to its DHCP request from the cable operator’s CMTS, but the responding DHCP server did not include all of the required fields in the message. Please refer to appendix C of the DOCSIS 1.0 RF specification, appendix D of the DOCSIS

1.1RF specification, appendix D of the DOCSIS 2.0 RF specification, and RFC 868 for further information. Reconfigure the DHCP server so that it sends all of the required fields.

SYNC Timing Synchronization failure - Failed to acquire FEC framing (Critical)

When attempting to lock on to the downstream channel your P-971M could not acquire forward error correction (FEC) framing.

SYNC Timing Synchronization failure - Failed to acquire MAC framing (Critical)

Your P-971M attempted to lock on to the downstream channel and was able to acquire forward error correction (FEC) framing, but then failed to lock on to media access control (MAC) framing. Note that this is not an ethernet MAC frametype.
