What is the difference between bsc and msc in gsm?
Mobile services Switching Center (MSC). It acts like a normal switching node of the PSTN or ISDN, and in addition provides all the functionality needed to handle a mobile subscriber, such as registration, authentication, location updating, handovers, and call routing to a roaming subscriber. These services are provided in conjuction with several functional entities, which together form the Network Subsystem. BSCs connect to a single MSC and each BSC typically controls several Base Transceiver Stations (BTSs).Some of the BTSs may be co-located at the BSC and the other may be remotely located and connected to the BSC by · microwave link or · leased line.
What kind of Technology was in 1970?
A lot of technology you still have today. Some you don't - in 1970, men went to the moon, which they cannot do now. There were computers, but no personal computers. No computers on a chip. No electronic calculators. We used typewriters and sent mail on paper. No cellphones, all phones were land lines except walkie-talkie radios used by military, fire, police, and taxi. The TV signal was analog, less than VGA, and color TV was still expensive enough that a lot of folks watched black and white. Satellite communication existed but was expensive, and so were cables under the sea. If you made an international call you generally used a human operator to set it up and it could cost you a day's salary to talk for 15 minutes. Cars were commonplace and jet aircraft were fairly normal, but still expensive. Deregulation, which reduced prices to make jet travel common, would not happen until President Carter. Trains, boats, and trucks were similar to today except containerization was still rare, so shipping things was still expensive and slow. Clothes, food, houses, those things were not so different than today. Just, not so globalized. Answering machines were rare and expensive. Reel to reel tape recorders were expensive and unusual, mostly used in studios. Cassettes (even 8-track) were not around yet. A small transistor radio was about the size of a paperback book. No Walkman, no boom-box. MacDonalds was very new and not found in all cities. Traffic lights were on a fixed cycle, they did not detect cars waiting. Radio was AM or FM, there were no digital technologies for voice or video, except for using digital encoding (similar to ISDN or 8-bit WAV) for some long distance lines. Aspirin was still the painkiller, and penicillin was still the antibiotic. Heart transplants had been done? Medical science was not too clear on what caused heart disease, and there were no cures for cancer apart from surgery. There was not yet a consensus that smoking caused cancer. No nanotechnology, actually not even microtechnology. But most kinds of heat engines - steam, gasoline, diesel, jet - were almost as good as today, and so were electric generators and motors. The USA and Canada took electricity to be normal, as did most of western Europe and Japan.
The speed of BRI ISDN interface is?
Maximum speed supported by ISDN BRI is 128 Kbps
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
When was ISDN Show created?
ISDN Show was created in 1997.
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 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.
Full name of ISDN?
ISDN stands for Integrated Services Digital Network
Why T1 better than ISDN?
ISDN VS T1 Both are Digital, T1 is 24 Channels ISDN is 2. Each Channel is 64K ISDN = 2 Voice or 128Kbps T1 = 23 Voice Channels or 1.5Mbps www.intelletrace.com
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 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.
