Internet and TV via E1 digital stream?

Question

Computer networks

Can the E1 digital stream transmit Internet data and television, or is it only for voice?
If yes, then I need to provide the n-th number of subscribers with Internet at a speed of 5 Mbps
It was calculated according to the Erlang table that one subscriber needs to allocate 1 channel
Since the whole thing is transmitted in digital form, it is logical to use digital
streams
bit rate E0 = 64kbit/s
Further ascending E1,E2,... There the number of channels increases but not their bandwidth
Please explain what am I doing wrong?

Answer 1

By increasing the number of channels, their bandwidth also increases, since in any combination of channels there is an additional control channel that controls the total bandwidth.
If you are not familiar with PRI, BRI - it is worth reading how they are combined and reduced to E1.

Answer 2

Read the article on Habré.
In short, there are devices, multiplexers / demultiplexers, that can cut the incoming stream into channels of 64 kilobits on one side and collect it in a heap on the other side.
5 megabits will fit into E2, for example, if you look at the plate from the article.
