3.2.3
3.2.3.1
Signals controlling and indicating the internal state of all U
are called INFOs. Four different INFOs (INFO 0, 1W, 1, 2, 3, 4) may be sent over the
U
Activation,...). When the line is deactivated, INFO 0 (=no signal on the line) is exchanged
by the U
When the line is activated, INFO 3 (in upstream direction) and INFO 4 (in downstream
direction) are continuously sent. INFO 3 and 4 contain the transmitted data (B1, B2, D,
M). INFO 1/2 are used for activation and synchronization.
