What do ISDN and DSL stand for?

modem
What is difference between lease line and ISDN line?
Leased line is a permanent fast internet connection. Unlike ISDN If needed you can connect your company with a very fast leased line from 64k - 2MBs while ISDN maximum speed is 128 K. A leased line is an ideal solution for a company who wish to trade on-line 24 hours a day. For users with small capacity demands ISDN offers three distinct advantages over dedicated leased line: Cost. Because ISDN is an on-demand technology, you only pay for the time each B channel is active.
What is Protocol Stack?
Integrated Services Digital Network (ISDN) is a digital, point-to-point network capable of transmitting speeds of about 2Mbps. A computer connects to an ISDN line via an ISDN adapter and uses the same type of wiring as a Telephone wire. The only difference is ISDN can carry analog (voice) and digital signals, so it can be used to connect to the internet. It can be connected by the phone company but it is rarely used as it needs special equipment and is more expensive than other way.
ISDN network security concerns?
What is ISDN? As a short word, some network engineers use ISDN network terminology for WAN connection using ISDN technology. ISDN stands for Integrated Services Digital Network which provides switched (dialed) digital WAN services in increment of 64 Kbps.ISDN Network availability is widespread, but you can still find places where it is simply not available. One key reason to use dialed connections of any kind, including ISDN network, might be to send and receive data for only short periods of time. Routers frequently use ISDN network to create a backup link when their primary leased line or Frame Relay connection is lost. ISDN technology uses T-carrier technology to quickly and efficiently send digital data streams over existing phone lines.ISDN network ChannelISDN network includes two types of interfaces: Basic Rate Interface (BRI) and Primary Rate Interface (PRI). Both BRI and PRI inISDN technology provide multiple digital bearer channels (B channels), over which temporary connections can be made and data can be sent. Because both BRI and PRI have multiple B channels, a single BRI or PRI line can have concurrent digital dial circuits to multiple sites, or multiple circuits to the same remote router to increase available bandwidth to that site.
What is Integrated Services Digital Network?
An isdn stands for integrating services digital network ,it is a communication media througt which we can transmitte our voice,video and data, in isdn line two modem are used to for commnication one at source and other at the destination ,these modems are called isdn modem this is Qadar wafa from Kabul qadarwafa_4all@yahoo.com qadarwafa@multinet.af qadar-08@hotmail.com
What is the type of telephone line that provides connection with transmission speeds in the range of 56kbps or 45 mbps or more?
56 kbps is ISDN (Integrated Services Digital Network), which uses a switched circuit to connect from point to point. 45 Mbps is probably DS3.
What is the difference between ISDN and DSL?
DSL vs ISDN ConnectionDSL, or Digital Subscriber Line, make use of existing telephone lines to transfer data to users at high speeds - as much as 100 times faster than standard analog modems. With the help of DSL, all websites which usually takes minutes to download through a dial-up connection can be downloaded in seconds. In addition to this, huge files can be delivered in seconds, and bandwidth-hogging applications such as online meetings and video cams work efficiently. ISDN ConnectionISDN, or Integrated Services Digital Network, on the other hand uses phone lines in use to deliver data, voice and fax transmissions over the same phone line. Till the time DSL was introduced, ISDN was considered as the least expensive option for small and medium-sized companies to get a fast digital connection to the Internet or a corporate Local Area Network (LAN). ISDN connection transfers at speed up to 128 kbps, considerably faster than a dial-up modem connectionDSL vs ISDNThe DSL vs ISDN table given below highlights key differences between both the technologies :DSL vs ISDN Connection ISDN ConnectionMaximum Speed 128kbpsDSL ConnectionDSL Speed - Average 384 kbpsDSL Speed - Top Speed 1.5kbpsFeaturesConsistent Data RateYesYesYesSame Speed Both DirectionsYesYesYesPer Minute Usage FeesYesNot ApplicableNot ApplicableTransfer Rate in seconds100 KB Word File831500 KB PDF attachement391331 MB image file782672 MB Power Point file1565213As shown in the DSL vs ISDN table above, DSL main advantage over ISDN is even the slowest DSL connection is still faster than any ISDN connection available. In addition, since DSL is "always on," there are no per-minute charges.

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.
