Why was DSL not used in the early days of the internet? Did the technology require faster chips that weren’t available at the time?
In: Technology
All the infrastructure was made for phone lines. You could only send sound waves no higher then 4kHz in frequency and of limited quality. Dialup would work over this phone network without any changes to any of the infrastructure in the network. It is even still used today in certain situations. With T1, ISDN, ADSL and now fiber you need to upgrade the entire network infrastructure to these standards. You need to replace the phone exchange with new and modern equipment. But dialup did not require any changes. You could technically run dialup over old phone exchanges from the 1880s if you wanted, but you can not do that with DSL. The only part of the phone system you can keep when upgrading from dialup to DSL is the phone lines.
