How to understand communication networks?

Question

Computer networks

Starting from the E1 stream, PDH, SDH, WDM. Further Ethernet, protocols TCP/Ip. And most importantly, how it all interacts with each other. Through what equipment different networks are interfaced, for example, Ethernet and SDH, circuit and packet switching. Maybe there is literature where all this is consistently stated. Thanks
