Overview
The figure below shows the general architecture of a digital exchange.

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.
