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.
Broadband ISDN offers higher data transfer rates (up to 2 Mbps) compared to narrowband ISDN (up to 128 Kbps). Broadband ISDN also supports the transmission of multimedia applications, while narrowband ISDN is mainly used for voice, data, and video conferencing.

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 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.
What is difference between ATM and ISDN?
1-ISDN is a circuit switching where as ATM is a packet switching. 2-ISDN is a point to point fixed bandwidth where as ATM is a variable bandwidth. By----- RAHUL SINGH ABES IT GHAZIABAD
What is the slowest transmission method for broadband technology?
ISDN (64k) is currently the slowest transmission method for broadband. Anything lower is deemed as "dial-up"(56k).

Difference between Narrowband and broadband in ce-03.?
Dial-Up Internet: A dial-up Internet connection is the most basic and therefore the slowest type of Internet connection that you can get. Connection rates for dial-up modems tend to fall between 2,400 bps & 56,000 bps, which is incredibly slow for today's high speed Internet and applications. Dial-up modems are attached internally or externally to a given computer, and then connected using a standard telephone cable. All in all, dial-up Internet connections are outdated and representative of an older and more basic Internet. ISDN: ISDN (Integrated Services Digital Network) Internet connections are a type of digital telephone connection. ISDN connections straddle the line between basic narrowband Internet connections and more advanced broadband Internet connections due to the fact that Basic Rate Interface (BRI) ISDN connections transmit data right around the broadband cutoff at 100 Kbps. Although a better Internet connection option than dial-up, ISDN connections are still more or less outdated. Digital Cable Broadband: Cable broadband Internet connections are the most common type of broadband service. Connecting to the Internet via your cable television signal, cable broadband Internet connections offer data transfer rates of approximately 1.5 Mbps, far exceeding those offered by either dial-up or ISDN connection types. DSL: Digital Subscriber Line Internet connections are the second most common type of broadband service offering data transfer speeds similar to those of cable broadband (_1.5 Mbps). DSL services connect to the Internet via copper telephone wires. The difference between DSL and dial-up / ISDN is that a DSL Internet connection uses a high speed dedicated circuit filtering out standard phone calls and Internet signals. WI-FI: Wireless Fidelity Internet Connections are currently the hot commodity in high speed connectivity. They boast similar transfer speeds as digital cable and DSL broadband, but they don't require any type of physical connection in order to transmit/receive a signal. T-Carrier Broadband: T-Carrier Internet connections are some of the fastest available in the world and are generally reserved for use by large businesses and universities. T1 and T3 Internet connections are the most common T-Carrier types, and can cost as much as $800 and $15,000 per month respectively. T-1 lines boast speeds of 1.54 Mbps whilst T3 lines boast astounding speeds of around 45 Mbps. OC24: An OC24 (Optical Carrier level 24) Internet connection is a fiber optic connection capable of transferring data at a mind-boggling rate of 1.244 Gbps. This is pretty much the fastest Internet connection that you can get and generally serves as the backbone of various NAPS (Network Access Points).
The difference between PSTN and ISDN in hsdpa?
WHAT IS THE DIFFERENCE BETWEEN ISDN AND PSTN ? The PSTN is the Public Switched Telephone Network and is therefore a service provided by a telecommunications company. The ISDN is the Integrated Services Digital Network and is a technology, providing digital end to end connectivity. However, calls originating from an ISDN site, will transverse the PSTN in order to be received by the called party. The call received by the called party, may be digital, if they also have ISDN service, or the call may be converted by the central office to meet the technology being used by the receiving party.
What is the difference between ISDN and SS7?
The Integrated Services Digital Network (ISDN) uses Digital Subscriber Signalling System No. 1 (DSS1) protocol interfaces to connect subscribers to the network. These are User-to-Network (UNI) interfaces. Signalling System No. 7 (SS7) is a suite of signalling protocols used in Network-to-Network (NNI) interfaces. These are connections between network elements within the ISDN.
What companies provide good, inexpensive broadband Internet services?
TheBroadbandGuide.com is a directory of Broadband Internet Provider that listed all home broadband internet access providers for categories like DSL Internet, Cable Internet, ISDN Internet, Wireless Internet and Satellite Internet.
What is the basic difference between ISDN and ADSN connection?
With ISDN you can implement ASDN. ISDN is a way of transmitting digital signals on a network - fiber or analog copper. It allows "virtual circuits" to be configured and bandwidth reduced or raised as needed. This is controlled by signalling messages that goes on a dedicated part of the lines. ASDN is a way of coding signals on a copper wire - where the signals can be ISDN lines. ISDN is the core network technology in the GSM mobile network, which allows this to set up phone connections, and keep these connected as you call while you move around.
