4.3.4 Transparent Data
DLI_PROT_SEND_TRANS_DATA can be used only when SLC envelope service is configured.
It can not be used when SLC protocol service is configured. The header formats are
detailed in Section 5.15 on page 80.
DLI_PROT_SEND_TRANS_DATA contains a single SLC block. The application writes this
command to the ICP to transmit a control block or an information block through the
WAN interface to the SLC network. The application reads this response when the ICP
reports a block received from the WAN interface to the SLC network. The application is
responsible for handling all SLC protocol requirements beyond the simple SLC enve-
lope service supported by the ICP. See Section 2.1 on page 21.
