4. Communications at 128 Kbps – Inverse Multiplex:
Certain algorithms permit the compression of the signal at bit-rates other
than 64Kbps, for example at 128Kbps. With the ProntoNet it is possible to
send or receive audio compressed at 128 Kbps using both the B channels
of the basic rate ISDN connection. This is done by using ‘inverse multiplex’
techniques that split the transmission of the full 128 Kbps over two
channels of 64 Kbps and then sum the parts together again at the other
end.
Inverse Multiplex is often known as ‘bonding’
5. Communications combining 128 and 64 Kbps: It is possible to
transmit encoding audio at 128 Kbps and to receive decoding audio at
64 Kbps or vice versa. Here below there are different examples of it.
