ABSTRACT:
A first group of asynchronous clock converters effect the conversion between a DNE clock and an RDT clock to which DS-0 data and signalling data are synchronized, for the data items which are transferred between a cross-connector and a DNE. A second group of asynchronous clock converters effect the conversion between a CPE clock and the RDT clock to which DS-0 data and signalling data are synchronized, for the data items which are transferred between the cross-connector and a CPE. As a result, cross-connect processes based on the single RDT clock are realized, and loop timings are guaranteed for the DNE and the CPE.
