The layer-1 activation / deactivation is controlled by an internal state machine via the
IOM-2 C/I0 channel. The ISAC-SX TE layer-1 control flow is shown in
Figure 30
In the following sections the layer-1 control by the ISAC-SX TE state machine will be
described. For the description of the IOM-2 C/I0 channel see also
The layer-1 functions are controlled by commands issued via the CIX0 register. These
commands, sent over the IOM-2 C/I channel 0 to layer 1, trigger certain procedures,
such as activation/deactivation, switching of test loops and transmission of special pulse
patterns. These procedures are governed by layer-1 state diagrams. Responses from
layer 1 are obtained by reading the CIR0 register after a CIC interrupt (ISTA).
The state diagrams of the ISAC-SX TE are shown in
activation/deactivation implemented by the ISAC-SX TE agrees with the requirements
set forth in ITU recommendations. State identifiers F1-F8 are in accordance with ITU
I.430.
State machines are the key to understanding the transceiver part of the ISAC-SX TE.
They include all information relevant to the user and enable him to understand and
predict the behaviour of the ISAC-SX TE. The state diagram notation is given in
