Regulating Termination Charges for Telecommunications Networks

SSRN Electronic Journal, 2000
This paper considers the effects of regulating termination for interconnected, but otherwise unregulated, telecommunications networks. We develop two models, the first that involves fixed market shares and the second, based on the work of Laffont, Rey and Tirole (1998a), which allows for subscriber competition. We show that if a dominant network (i.e.

Terminal detach scenarios in future mobile telecommunications

International Journal of Wireless Information Networks, 1994
In mobile telecommunications the network should monitor the terminal status, i.e.,switched on, switched off, busy. Once a mobile terminal is switched on, it automatically informs the network about its status (attachment action). However, regarding the way that the network can identify that a terminal is switched off (detachment), there are three ...

Telecommunications-Terminal Mute Detection

The Journal of the Acoustical Society of America, 2011
The subject matter provides a method that enable detecting if a party engaged into a tele-conference call is attempting to engage into conversation while a microphone is in a mute mode. The method provides receiving of a signal. The signal is then analyzed to determining if a party is attempting to engage into conversation. If it is determined that the

Musculoskeletal disorders among visual display terminal users in a telecommunications company

Ergonomics, 1994
The relationship between workplace factors and work-related upper extremity musculoskeletal disorders (UE disorders) was assessed in a cross-sectional study of 533 telecommunication employees utilizing video display terminals (VDTs). Cases of UE disorders were defined using symptom questionnaires and physical examinations.

Low reflectance terminations and connections for duplex fiber-optic telecommunication links

Applied Optics, 1981
The signal-to-noise ratio of full duplex fiber-optic telecommunication links using a single fiber with directional couplers is shown to be extremely sensitive to reflections from fiber end terminations and fiber-to-fiber connections. This paper will examine a series of experimental measurements made to determine the reflectance coefficients of several ...
