Explain the number unobtainable tone in strowger telephony, Computer Engineering

Assignment Help:

Explain the number unobtainable tone in strowger telephony with waveforms and the timings.

In the following figure illustrates the number unobtainable tone that is continuous 400 Hz signal. This tone might be sent to the calling subscriber because of a variety of reasons as the called party line is out of order or disconnected, and an error in dialing leading to the selection of a spare line. In the several exchanges the number unobtainable tone is 400 Hz intermittent along with 2.5 s on period and 0.5 s off period.
