8.4 LAPD Primitives

The following table summarizes supported LAPD primitives: Message Type Description DL_DA_IN Indicates that a packet of acknowledged data has been received by the trunk from the remote party. DL_DA_RQ Sent by the application to the AG ISDN protocol stack to request the stack to transmit a packet of acknowledged data. DL_EST_CO Indicates that equipment on the remote side of the ISDN trunk has acknowledged a SABME message sent by the ISDN protocol stack, and has sent back a UA message indicating that the data link is established. DL_EST_IN Indicates that a SABME message has been received by the AG ISDN protocol stack. The stack automatically acknowledges the message by sending back a UA message, and establishes the data link. DL_EST_RQ Sent by the application to the AG ISDN protocol stack to request the stack to establish a data link. The stack transmits a SABME message over the trunk. DL_REL_IN If the AG ISDN software is in the IDLE state, this message indicates that an establishment request sent by the AG ISDN protocol stack was not successfully answered. If the software is in the DATA_LINK_ESTABLISHED state, this message indicates that the data link has been broken. DL_U_DA_IN Indicates that a packet of unacknowledged data has been received by the trunk from the remote party. DL_U_DA_RQ Sent by the application to the AG ISDN protocol stack to request the stack to transmit a packet of unacknowledged data.
