The Analog circuits are of two types:
- Output to generate an analog signal to the outside (uses an Output+GNA pair).
- Input to receive an analog signal from the outside (uses an Input+GNA pair).
Connection of these signals is carried out through the analog matrix
configured by the operator dialogue.
- The matrix is configured COFIDEC -> Analog for the Output signals.
- The matrix is configured Analog -> COFIDEC for the Input signals.
The Analog circuits can be used for example:
- in output, to generate to the outside a signal corresponding to analysis of the contents
of a B channel (use of both Output 1 and Output 2 signals).
- in input / output, to connect to a B channel, the analog two-way signals of an analog
equipment-item (Input1+Output1 use).
