ABSTRACT:
A transmission apparatus includes an aggregate-side interface unit coupled to an optical transmission line, a cross-connect unit which performs cross-connect with respect to a synchronized digital signal supplied from the aggregate-side interface unit, and a network signal processing unit which switches the synchronized digital signal in a unit of a network signal as the synchronized digital signal is supplied from the cross-connect unit.
