An optical transport network (OTN) is a digital wrapper that encapsulates frames of data, to allow multiple data sources to be sent on the same channel. This creates an optical virtual private network for each client signal. ITU-T defines an optical transport network as a set of optical network elements (ONE) connected by optical fiber links ...
Automatically switched optical network. Automatically Switched Optical Network (ASON) is a concept for the evolution of transport networks which allows for dynamic policy-driven control of an optical or SDH network based on signaling between a user and components of the network. [1] Its aim is to automate the resource and connection management ...
Open Transport Network (OTN) is a flexible private communication network based on fiber optic technology, manufactured by OTN Systems. It is a networking technology used in vast, private networks with a great diversity of communication requirements, such as subway systems, pipelines, the mining industry, tunnels and the like (ref).
ITU-T Recommendation G.709 Interfaces for the Optical Transport Network (OTN) describes a means of communicating data over an optical network. [1] It is a standardized method for transparent transport of services over optical wavelengths in DWDM systems. It is also known as Optical Transport Hierarchy (OTH) standard.
Task switching, or set-shifting, is an executive function that involves the ability to unconsciously shift attention between one task and another. In contrast, cognitive shifting is a very similar executive function, but it involves conscious (not unconscious) change in attention. Together, these two functions are subcategories of the broader ...
Psychology. Cognitive flexibility[note 1] is an intrinsic property of a cognitive system often associated with the mental ability to adjust its activity and content, switch between different task rules and corresponding behavioral responses, maintain multiple concepts simultaneously and shift internal attention between them. [1] The term ...
Cognitive shifting is the mental process of consciously redirecting one's attention from one fixation to another. In contrast, if this process happened unconsciously, then it is referred to as task switching. Both are forms of cognitive flexibility. In the general framework of cognitive therapy and awareness management, cognitive shifting ...
A person paying close visual attention to their use of a bottle opener, ignoring the other people around them. Attentional control, colloquially referred to as concentration, refers to an individual's capacity to choose what they pay attention to and what they ignore. [1] It is also known as endogenous attention or executive attention.
