Answer Posted / sukhbir singh
We need to calculate why a Time Slot occupies 64 bits.
Lets Start-
Audible Voice Frequency is of range 3.5Khz to 4Khz. As per
sampleing theorm, rate of sampling should be twice the max.
freq. i.e. 4X2=8Khz which means you require 8000samples per
second to quantize the analog voice signal.
As a fact, one sample requires 8-bits.
Therefore, 8000 samples would require - 8000X8=64000bits
i.e. 1 voice sample will need at least 64kbps to travel.
Now, E1 is designed as such to have 32 time slots, each
with a BW of 64kbps.
Thus, E1=32X64=2048 Kbit i.e. 2Mbps
Hope this clarifies.
