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 is the advantages of multiplexing?
Because, the higher the data rate, the more cost effective the transmission facility. That is, for a given application and over a given distance, the cost per kbps decline with an increase in the data rate of the transmission facility.
Difference between pri and leased line?
Leased lines are basicaly a data link / line, which is dedicated for data transmission between registered end to end network for enterprise users where as, PRI (Primary Rate Interface) is one of the service which is used by ISDN connection .It uses channel wise data transmission between the networks.The Primary Rate Interface consists of 23 B-channels and one 64 Kpbs D-channel using a T-1 line or 30 B-channels and 1 D-channel using an E1 line. Thus, a Primary Rate Interface user on a T-1 line can have up to 1.544 Mbps service or up to 2.048 Mbps service on an E1 line.
Which of the following is not a common usb data rate?
1.5Mbps
What is baud rate of the modem?
whats the baud rate of the modem of the computer
What are key factors that can affect channel capacity?
Channel capacity - It is the rate at which the data can be transmitted over a given path, or channel, under the given conditions. Key factors affecting the channel capacity are- Data rate- speed of data transmission measured in bits per second. Bandwidth – Maximum. Bandwidth, noise, and error rate.
What key factors affect channel capacity?
The following are the major factors can affect network channel capacity: 1.Data rate-----Bits per second 2.Bandwidth---Cycles per second (Hertz) 3.Error rate
Noisy and Noiseless channels in Data Communication?
A. Noisy Channel: Defines theoretical maximum bit rate for Noisy Channel: Capacity=Bandwidth X log2(1+SNR) Noiseless Channel: Defines theoretical maximum bit rate for Noiseless Channel: Bit Rate=2 X Bandwidth X log2L
How is the channel used in the digital communucation system?
The channel used in a digital communication system is used to convey an information signal. A channel has certain capacity for putting in information that is measured by bandwidth in Hz or data rate.
What does the shannon capacity have to do with communication?
It has to do with data communication. It is called the Shannon channel capacity theory where double the bandwidth equals double the highest data rate. This is of course theoretically and does not take into account white noise (thermal noise), impulse noise, attenuation distortion or delay distortion.

Relation between channel capacity and bandwidth?
According to Shannon's Channel Capacity Equation: R = W*log2(1 + C/N) = W*log2(1+ SNR) Where, R = Maximum Data rate (symbol rate) W = Bw = Nyquist Bandwidth = samples/sec = 1/Ts C = Carrier Power N = Total Noise Power SNR = Signal to Noise Ratio
What measurement unit describes the speed and capacity of a communication channel?
The speed and capacity of a communication channel are typically measured in bits per second (bps) or its multiples such as kilobits per second (kbps), megabits per second (Mbps), or gigabits per second (Gbps). These units indicate the rate at which data can be transmitted through the channel.
What is the difference between the channel spacing and the transmission bandwidth?
Bandwidth is the measure of range or band of frequencies that a channel or path can handle at a maximum rate. whereas, throughput is the average rate of successful message delivery over a communication channel. and Goodput is simply the changing in throughput rate.
What is Maximum data rate of binary signals on a noiseless 3khz channel is?
Nyquist theorem for noiseless channel C= 2Blog22n. C= channel capacity in bps B= bandwidth in KHz 1 KHz= 1000 Hz C= 2*3*1000*log22. =6000 * log2 2. =6000 =6000 bps ..................................... Anu Chawla
Why does increasing the capacity of cache tend to increase its hit rate?
Increasing the cache capacity means more data can be stored in the cache, reducing the likelihood of data being evicted before it is accessed again. This results in a higher probability of finding requested data in the cache, increasing the hit rate as a result.
Which factor affect data rate of a link?
the bandwidth and the signal to noise ratio
