D (Delta) channel: 16 kbps

  • D-channel takes care of call set-up, call control (call forwarding, call waiting, etc.), and maintenance
  • Control and maintenance can be done in real-time in D-channel while B-channel is still transmitting data

What do ISDN and DSL stand for?

ISDN: Integrated Services Digital Network DSL: Digital Subscriber Line


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.


Hardware and software needed for ISDN and ADSL?

For ISDN (Integrated Services Digital Network), the hardware required typically includes an ISDN terminal adapter or an ISDN modem, which connects to the user's device and the ISDN line. On the software side, users may need drivers or configuration software to manage the connection. In contrast, ADSL (Asymmetric Digital Subscriber Line) requires an ADSL modem or router to connect to the telephone line, and it usually includes built-in software for configuration and management. Additionally, users may need a compatible computer or device with an Ethernet port to connect to the ADSL modem.


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.

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.
