  We study the phase diagram of the sine circle map lattice with random initial
conditions and identify the various types of dynamical behaviour which appear
here. We focus on the regions which show spatio-temporal intermittency and
characterise the accompanying scaling behaviour. Directed percolation exponents
are seen at some points in the parameter space in the neighbourhood of
bifurcation boundaries. We discuss this behaviour as well as other types of
behaviour seen in the parameter space in the context of the phase diagram.
