Q. What do you mean by sub address?
A sub address, though a part of the ISDN address, isn't considered as an integral part of the numbering scheme. Sub address is carried in a separate field in user-network interface message. It may or may not be present in a call setup message. Sub address is normally transparent to the network and it the equipment at the destination that analyses sub address information for routing to the appropriate terminal. A typical address using both ISDN number and sub address is displayed in figure. Here an ISDN number identifies a T reference point and a sub address one of the many S reference points. On the other hand, as reference point can also be addressed by using direct inward dialing (DID) feature.
Question 1 Explain the term telecommunication and how its implied meaning has changed over time and outline major developments in telecommunication technologies Question 2
Q. Explain Current-to-Current Amplifier ? The circuit given in Figure is to amplify a current fed to the input of the op amp. Applying KCL at Y, i 1 + i S = i o S
With a maximum excess delay of and a chip duration of , the multipath components fall in delay bins. This means that we experience leakage of energy between chips and the channel i
Low-pass electronic filter: The capacitors and inductors are the reactive elements of the filter. The number of elements ascertains the order of the filter. In this situation,
