General Exchange Architecture
System Background
Digital exchanges put calls through by newly arranging the speech signals coded with 8-bit words
(PCM time-slots). The code words are transmitted serially on PCM lines. The sampling frequency
of 8 kHz produces PCM frames with a duration of 125 s. The transmission rate on the line
determines how many code words (speech channels) can be accommodated within a sampling
period. With a data rate of 2048 kbit/s for example, there are 32 time-slots of 8 bits each. 4 lines
with a data rate of 8192 kbit/s have a transmission capacity of 512 channels.
