3)Example of protocol

The signals shaded in the following figure are the most important signals in the procedure.

-Late start

The receiver cannot detect CM signal while it is sending the ANSam signal. Therefore, it sends a DIS signal to inform the availability of V.8 support. The transmitter sends a CI signal that causes the receiver to send another ANSam signal which makes the receiver move to the V.8 procedure.
