  We constructed a class of non-maximally entangled mixed states \cite{roy2010}
and extensively studied its entanglement properties and also their usefulness
as teleportation channels. In this article, we revisited our constructed state
and have studied it from three different perspectives. Since every entangled
state is associated with an witness operator, we have found a suitable
entanglement as well as teleportation witness for our non-maximally entangled
mixed states. We considered the noisy channel's effects on our constructed
state and to see whether it affects the states' capacity as teleportation
channel. For this purpose we have mainly emphasized on amplitude damping
channel. A comparative study with concurrence and quantum discord of the state
of ref. \cite{roy2010} has also been carried out here.
