A method and device for improving flexibility and transparency at the nodes of synchronous hierarchy data transport networks is disclosed. The method uses, as a network flexibility point, a Multiplex Section Digital Cross Connect MS-DXC and SDH or WDM terminals for mere transport need. The MSOH, and possibly RSOH, sections of the STM-N frame of the high bit-rate SDH signal are handled by the MS digital cross connect in a manner equivalent to the payload section thus providing transparency for the payload and for the MSOH section, as well as, possibly, for the RSOH section too.
