This notification is generated whenever an ANCP session
goes down. A session can go down for several reasons:
1) The ANCP session can be deleted by a manager from the
ancpAnSessionConfigTable, and hence it will also be
removed from the ancpAnCurrentSessionTable.
2) The session can go operational down due to some
malfunction in the network, the AN, or the NAS. In
this case, the ANCP session will be still in the
ancpAnSessionConfigTable and ancpAnCurrentSessionTable,
but the ancpAnCurrentSessionState moves from the estab
state to another state.
This notification is only generated when
ancpAnSessionConfigNotifyDnEnable of this session is set
to true.

This notification is generated when an ANCP session enters
the estab state as given by ancpAnCurrentSessionState.
Since ancpAnCurrentSessionAnInstance identifies the ANCP
session uniquely the other attributes can be derived from
this attribute.
This notification is only generated when
ancpAnSessionConfigNotifyUpEnable of this session is set
to true.
