The present document is applicable to international constant bit rate digital paths at or above 64 kbit/s supported by digital networks. International constant bit rate digital paths may be based on the Plesiochronous Digital Hierarchy (PDH), the Synchronous Digital Hierarchy (SDH) or some other transport network such as cell-based. The present document is generic in that it defines parameters and requirements independent of the physical transport network providing the paths.
