What is a difference between broadband ISDN and narrowband ISDN?
Here are some differences between broadband ISDN and narrowband ISDN: 1) Narrowband ISDN uses 64 kb/s channel, while broadband ISDN uses 100 mb/s channels. 2) Broadband uses call relay, while narrowband uses frame relay. 3) In narrowband, ISDN information carries narrow frequency, while in broadband, ISDN uses a wide band of frequency.
Which best describes the benefit of using Frame Relay as opposed to a leased line or ISDN service?
Your materials are out of date. No-one much uses Frame Relay or leased line these days, and ISDN has essentially vanished except for maybe a few antique lines. Find something better to study.
What is the function of ISDN's data link layer?
Ensures that control and signaling information flows properly and is received
What is N-isdn and B-isdn in detail please?
first of all isdn is integrated sevice digital netork it is used for all the communications n -isdn and b-isdn are the parts of isdn n -isdn is the first generation isdn it uses 64-kpbs channel and has acircuit switching implementation b-isdn is the second generation isdn it supports uery high data rates 100 and more mbps it supports packet switching
What is the difference between b-isdn and n-isdn?
B-ISDN is a circuit switching process. The N-ISDN is a virtual switching process (packets). ISDN stands for Integrated Service Digital Network.
What is a TE2 device used for in an ISDN connection?
Connecting a non-ISDN terminal to ISDN through a TA
What could case frame relay to no longer be necessary in the future?
Frame relay was designed to be used with ISDN networks. That technology have been surpassed by broadband DSL and fiber optic networks which don't use frame relay so it gradually being phased out.
When was ISDN Show created?
ISDN Show was created in 1997.
A company is investigating the use of an isdn service to act as backup for the ASDL service they use?
a company is investigating the use of an isdn service to act as backup for the ASDL service they use to communicate with branch offices.they discover that the isdn bri service uses two 64 kb/s B channels which function do the b channels perform
What is a difference between broadband ISDN and narrow band ISDN?
The most important development in the computer communications industry in the 1990s is the evolution of the integrated services digital network (ISDN) and broadband ISDN (B-ISDN). The ISDN and B-ISDN have had a dramatic impact on the planning and deployment of intelligent digital networks providing integrated services for voice, data and video. Further, the work on the ISDN and B-ISDN standards has led to the development of two major new networking technologies; frame relay and asynchronous transfer mode (ATM). Frame relay and ATM have become the essential ingredients in developing high-speed networks for local, metropolitan and wider area applications. The ISDN is intended to be a worldwide public telecommunications network to replace existing public telecommunication networks and deliver a wide variety of services. The ISDN is defined by the standardization of user interfaces and implemented as a set of digital switches and paths supporting a broad range of traffic types and providing value added processing services. In practice, there are multiple networks, implemented within national boundaries but from the user's point of view, the eventual widespread deployment of ISDN will lead to a single, uniformly accessible, worldwide network. The narrowband ISDN is based on the use of a 64 kbps channel as the basic unit of switching and has a circuit switching orientation. The major technical contribution of the narrowband ISDN effort has been frame relay. The B-ISDN supports very high data rates (100s of Mbps) and has a packet switching orientation. The major technical contribution of the B-ISDN effort has been asynchronous transfer mode, also known as cell relay. CIRCUIT SWITCHING The circuit switching is the dominant technology for both voice and data communications. Communication via circuit switching implies that there is a dedicated communication path between two stations. That path is a connected sequence of links between network nodes. On each physical link, a channel is dedicated to the connection. The three phases involved in a communication via circuit switching are circuit establishment, information transfer and circuit disconnect.
Can you use an ordinary telephone or fax machine over ISDN?
yes, we can but we need terminal adapter to connect with ISDN if ordinary line is used . terminal adapter use to convert non ISDN to ISDN.
What are advantages of using basic rate interface contention resolution in an ISDN network?
Avoiding frame collisions Avoiding transmission time lags Improving network Performance
