Operational Mode Command/Status Bits
The bits of this group are used during normal operation, hence they are evaluated in
every frame. They include all VIP receiver status bits and some of the command bits.
The operational mode command/status bits are buffered in the Data RAM.
The VIP receiver status bits do not reflect a status change, but the status itself, i.e. the
current value of the line interface INFOs, until the values change.
The FECV is only reported to the DELIC upon changes.
Command/Status Transmission
The command/status bits are transmitted/received by the TRANSIU at the same rate as
data transmission rate, starting with the 8 kHz FSC.
Transmit Direction
• The command information per VIP is prepared by the DSP in the VIPCMR0-2
• The command bits from initialization command group are prepared by the DSP in the
• TRANSIU operation mode command format in the Data RAM:
