"Current cable modem connectivity state, as specified

information is the CM status, as assumed by the CMTS,

other(1)
Any state other than below.
ranging(2)
The CMTS has received an Initial Ranging Request
message from the CM, and the ranging process is not
yet complete.
rangingAborted(3)
The CMTS has sent a Ranging Abort message to the CM.
rangingComplete(4)
The CMTS has sent a Ranging Complete message to the CM.
ipComplete(5)
The CMTS has received a DHCP reply message and
forwarded it to the CM.
registrationComplete(6)
The CMTS has sent a Registration Response message to
the CM.
accessDenied(7)
The CMTS has sent a Registration Aborted message
to the CM.
operational(8)
Value 8 is considered reserved and should not be defined
in future revisions of this MIB module to avoid conflict
with documented implementations that support value 8 to
indicate operational state after completing the BPI
initialization process.
registeredBPIInitializing(9)
Baseline Privacy (BPI) is enabled and the CMTS is in the
process of completing BPI initialization. This state
MAY last for a significant length of time if failures
occur during the initialization process. After
completion of BPI initialization, the CMTS will report
registrationComplete(6).
The CMTS only needs to report states it is able to
detect."
