Traffic Encryption Key (TEK) States
STATE_A_START The router is still completing the DOCSIS provisioning
process, or is still performing the KEK key exchange. If this
state persists, it indicates that KEK authorization failed, or that
BPI/BPI+ encryption was not enabled for the router in its
DOCSIS configuration file.
STATE_B_OP_WAIT The router has successfully completed the KEK key exchange,
has sent a key request to the CMTS, and is waiting for a reply.
STATE_C_OP_REAUTH_WAIT The router has sent a reauthorization request and is waiting for
a reply, or the TEK key has been declared invalid. BPI/BPI+
encryption has not yet begun. If this state persists, it indicates
that the TEK key exchange has failed.
STATE_D_OPERATIONAL The router has completed the TEK key exchange, and BPI or
BPI+ encryption is operational between the router and the
CMTS.
STATE_E_REKEY_WAIT The existing TEK keys have expired, and the router has
requested a key update from the CMTS.
STATE_F_REKEY_REAUTH_WAIT The router has requested a key update from the CMTS and is
waiting for a reply. BPI/BPI+ encryption can continue using
the existing keys until they expire.
