The Traffic Service Position System (TSPS) No. 1 (see Fig.
New telephone services are regularly being conceived which place large demands upon existing switching facilities--demands which are increasingly difficult to satisfy with electromechanical techniq
Digital storage in the Stored Program Control (SPC) 1A is provided by the piggyback twistor (PBT) memory store.
In a typical T S P S No.
At the outset of telephony, connections between telephones were established by operators through cords, plugs, and jacks at switchboards.
Dielectric optical waveguides have become interesting since it has been demonstrated that the losses of dielectric materials can be quite low.
In this letter, we demonstrate a module that simultaneously performs optical time-slot interchange and wavelength conversion of the bits in a 2.5-Gb/s data stream to achieve a reconfigurable time/w
A novel liquid microlens with photopolymerizable components is described (see Figure).
We report on the generation of an optical clock up to 1.2 THz using a Quantum Dash mode-locked laser and a spectral filter, selecting two or three lines, which are separated by the desired spacing.
For supporting a more efficient usage of available spectrum by mobile communication in unlicensed bands, a solution for robust and frequency agile receivers is proposed.
