Personal computers, PCs, require special security considerations, due to their proliferation, accessibility, and mobile nature.
A key element necessary to make ISDN Centrex services a commercial success is the development of new applications packages that build on and expand the functionality of basic ISDN services.
The rapid proliferation of heterogeneous devices, complex network architectures and distributed services leads to a growing demand for monitoring solutions.

A properly designed and installed metal chassis reduces radiated fields from Printed Circuit Boards (PCBs).
The choice of a modulation method or code for processing a signal preparatory to transmission over a communication channel depends on a multiplicity of conflicting parameters.
The popularity of multimedia services has introduced important new challenges for broadband access network management.
© 1983-2012 IEEE. Optical communications networks include basic components such as EDFAs and WSSs that present a polarization gain imbalance.
We demonstrate a novel polarization-division multiplexed (PDM) differential quadrature phase-shift keying (DQPSK) receiver.
The dependence of propagation performance on the signal baudrate is investigated by simulations for WDM PDM-16QAM systems operating at a spectral efficiency of 4 b/s/Hz.
