What is the maximum bandwidth for ISDN BRI?
the maximum data rate for ISDN BRI is 128 Kbps -Big-Elk
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
Does a primary key have to be an integer in an Access database?
No, it does not. A primary key can be different types of data, not just an integer.
What did ISDN do?
With the advent of the Integrated Service Digital Network (ISDN), the telecommunications network no longer had to separate voice, text, data, and image traffic

Which layer of the OSI model does ISDN Q921 operate?
data link
What is the function of ISDN modem?
LAN interconnect (WAN)Joins Local Area Networks on a dial-up basis. This is useful where there are low traffic volumes required between the two LANs for applications such as e-mail, remote printer access, or small file transfer on an intermittent basis.Video conferencingMeetings that use a Video Conference eliminate much of the expense and travel involved with conventional meetings. Fully interactive audio and video makes it almost like being there.ISDN leased line backupIf a dedicated data circuit is mission critical to your business, ISDN can be used as a cost-effective standby in the event of a communications failure in your primary link(s).Bandwidth on demandIf your peak traffic requirements cause congestion on your primary link(s) at certain time during the day, ISDN can be used to carry the excess capacity, therefore providing extra bandwidth on demand.Security monitoringISDN makes surveillance of remote sites possible, including enhancements such as remote scan and zoom. The live ISDN video link can be initiated via motion detectionHigh quality audioYou can achieve much higher audio quality using ISDN with special communications software - so much so that ISDN is the preferred service for broadcasting purposes.Group 4 FacsimileG4 faxes, the fastest and best quality faxes of today, require ISDN. They can provide very high quality reproduction and consistently faster transmission than traditional faxes.Bandwidth on demand data networksLarge bandwidths can be dialled on demand with Primary Rate ISDN, providing a highly flexible data network. This means you can increase or decrease data transfer capacity to multiple sites as and when required - and charges are based on the duration of your calls.
What is the relation between access and database?
Access is no security Database has security limited data can store in access we can specify the size and file growth. we can store n number of data's only primary key can specify in access. but in database we can specify primary key as well foreign keys and other keys.
What is the maximum data rate for ISDN BRI?
ISDN BRI is a Basic Rate Interface for ISDN networks (Intergrated Services Device Network). It consists of 2 Channels: B+D. B channel is used for data and voice and consists of two 64Kbps channels=128Kbps. D channel is used for the signal and control of the interface and is 16Kbps. Together the B+D chanels are refered to as 2B+D. The maximum data rate on a BRI is therefore 128Kbps. NOTE:PRI is Primary rate Interface which uses 23x64Kbps B channel and 1x64Kbps D channel (T-1)
what device to use if you were to connect your computer to an analog data service provider?
ISDN Adapter
What is ISDN and What is it's necessity?
Integrated service Digital network. ISDN is a circuit-switched telephone network system, that also provides access to packet switched networks, designed to allow digital transmission of voice and data over ordinary telephone copper wires, resulting in better voice quality than an analog phone. It offers circuit-switched connections (for either voice or data), and packet-switched connections (for data), in increments of 64 kbit/s. Another major market application is Internet access, where ISDN typically provides a maximum of 128 kbit/s in both upstream and downstream directions (which can be considered to be broadband speed, since it exceeds the narrowband speeds of standard analog 56k telephone lines). ISDN B-channels can be bonded to achieve a greater data rate, typically 3 or 4 BRIs (6 to 8 64 kbit/s channels) are bonded.
What is Primary file organization?
primary file organization says that how data itself is stored on the storage device. a secondary logical maintinance of physically stored data that helps us to speed access to the physically stored data.
