Synchronization of a Digital Network

IEEE Transactions on Communications, 1980
A brief description is given of synchronous and plesiochronous digital networks, with discussion of slip rate performance requirements. Various methods of synchronization are described with emphasis on the selection of the preselected alternate master-slave (PAMS) method.

Digital network synchronization

IEEE Communications Magazine, 1995
With respect to network timing, the introduction of SONET equipment into the public network offers both problems and opportunities. Wide-scale deployment of SONET equipment and the use of SONET line timing for reference distribution will eventually provide improved timing performance in terms of both wander and jitter.

Integrated services digital networks: Broadband networks

European Transactions on Telecommunications, 1991
AbstractThis paper deals with the final goal of the evolutionary process of the public telecommunication networks towards broadband capabilities (B‐ISDN), process which is based on the adoption of the Asynchronous Transfer Mode (ATM).At first, a critical analysis is carried out about the transfer modes which gave rise to the definition of ATM.

Network testing system for digital data networks

Computer Networks and ISDN Systems, 1986
Abstract The digital data exchange network testing systems (DNTS) is developed to enhance service quality and reduce maintenance costs in digital data networks. DNTS achieves quick, accurate and systematic fault detection and localization in networks by integrating network test facilities such as terminal, transmission and switching test facilities ...

Bugging the Digital Network

Information Systems Security, 1993
In the Spring 1992 issue of Information Systems Security, John Podesta addressed the FBI's attempt to ensure its ability to eavesdrop on digital communications by imposing a ‘truly radical solution’ on computer software and hardware vendors. As Podesta noted, law enforcement officials have identified three key issues associated with the transition from

Synchronization Techniques for Digital Networks

IEEE Journal on Selected Areas in Communications, 1986
A fault-tolerant network clock regenerator (NCR) will be analyzed, which consists of two digital phase-locked loops (DPLL), and which allows a dynamical configuration control and thus is able to meet CCITT's Recommendations concerning permissible slip rates, frequency inaccuracy, as well as phase jitter and wander.

Generalized digital waveguide networks

IEEE Transactions on Speech and Audio Processing, 2003
Digital waveguides are generalized to the multivariable case with the goal of maximizing generality while retaining robust numerical properties and simplicity of realization. Multivariable complex power is defined, and conditions for "medium passivity" are presented. Multivariable complex wave impedances, such as those deriving from multivariable lossy

Networking Standards at Digital

1985
This talk will examine computer networking standards as they affect Digital’s network products. Of particular importance is the work currently under way in ISO (and elsewhere) on Open Systems Interconnection, although there are other standards developments which must be taken into account.
