Abstract

Describes the requirements for the STM-N signals at the network node interface of a synchronous digital network, including B-ISDN in terms of: - bit rates; - frames structures; - formats for mapping and multiplexing of client signals (e.g., PDH, ATM and Ethernet) elements; - functionalities of the overheads.
