There are some very interesting wikis on telco multiplexer/de-multipexers and tech going back to the beginning. It is fascinating how many calls they could fit down the same line with the Network video link, how many they could without video, other services that most consumers never saw (directly) etc.

They had to develop IIRC phase delay equalizers to compensate for color distortion from the long lines transport.
