  In this paper we discuss mainly with our proposed non maximally entangled
mixed state defined in (Adhikari \textit{et. al}, \textit{Quant. Inf.
Comp.}\textbf{10}, No. 5, 0398, (2010)). We show that such non maximal
entangled state is dependent on its characteristic parameter. As has been
already shown, that for certain parameter range, the state could be used as a
teleportation channel, we show here that for some other ranges of parameter the
state behaves as a bound entangled state. We also show that for all values of
the characteristic parameter of the state, coherent information is always less
than zero, so that the state can never used in dense coding protocols. We
conjectured the existence of witnesses which can categorize dense codeable
states.
