E1.0 is essentially a 2Mbits/s connection.
In total you have 32 Time Slots. You have to exclude two Time slots as
they are used for signalling and Frame alignment / synchonisation.
Time Slot 0 (Frame Alignment / Synchronisation) and Time Slot 16 (signalling) are reserved.
This leaves you with 30 Time Slots to use.
For the Internet a connection of 64kbits/s is quite slow. You have to consider that a lot of the
content is rich and this means a lot more bandwidth will be required. You could group Time slots so that
you have provide more bandwidth to customers that are willing to pay.
