The author introduces basic concepts, technologies and a standard for the network node
interface (NNI) for synchronous digital networks. Basic requirements for such networks and …

The main concepts and interfacing and multiplexing techniques for an NNI (network node
interface) as set forth in CCITT (International Consultive Committee for Telephone and …

The authors describe a synchronous digital transmission system using the network node
interface (NNI) that compiles with CCITT recommendations G. 707, G. 708, and G. 709. To …

The author discusses the applications of the newer cross-connect systems that terminate
and cross-connect DS3-rate signals. He gives some background on the operation of the …

Synchronous equipment using the CCITT standard network node interface (NNI) is being
developed. The equipment consists of three kinds of modules: a skip-level multiplexer which …

A unified framework and terminology is presented for synchronization design in digital
systems, borrowing techniques and terminologies from digital system and digital …

The authors describe a broadband switch architecture that is able to offer both the
asynchronous and the circuit emulation transfer modes (ATM and CEM) for nonisochronous …

The integration of broadband services into ISDN (integrated services digital network)
requires the introduction of novel switching and transmission facilities. Service requirements …

N integrated digital network which combines digital transmission and switches can provide
efficient and economical paths to carry analog and digital information. Digital networks have …

The general aspects of timing and synchronization in digital communications networks are
reviewed. The properties of the links and nodes carrying and switching time-multiplexed …
