Dialogic® DSI SS7MD Programmer’s Manual Issue 3
•VPI
The VPI of the AAL5 stream to be monitored. The VPI must be viable in the mask configured in the ATM_MSG_CONFIG message.
•VCI
The VCI of the AAL5 stream to be monitored. The VCI value must be viable in the mask specified in the ATM_MSG_CONFIG message. Note: 0, 3, and 4 are reserved.
•mgmt_id
ID of management module for status updates.
Notes:
The VPI/VCI combination configured here must not match the default specified for the cell stream.
It is expected that the user has already configured the ATM cell stream to be monitored before this message has been sent, and that the monitoring link is removed before the cell stream is terminated.
Once the message has been received and processed by the management module, API_MSG_RX_IND messages will be sent to the module ID indicated (with the ID field set to the upper layer id).
AAL5 messages of length greater than the maximum configured for the underlying cell stream will be silently discarded. A count of discards may be retrieved via an ATM statistics request: ATM_MSG_R_STREAM_STATS.
