UPLF3
A timeout condition might have occurred because the system was not able to activate a switched link to a remote control point.
A possible cause is that a message was issued to the QSYSOPR message queue that pertains to the controller description selected by Advanced Peer-to-Peer Networking (APPN). However, no response to the message was provided.
This timeout also might have occurred because a previous session initiation request for the same local location, remote location, and mode name failed during the switched link activation.
This ends the procedure.
