SIPD and RMD are connected to AMCD through local IP sockets using Stentofon Simple Link Layer

  • The daemon send an idle frame to AMCD every 5? second.
  • If no idle frame is received from the daemon within 30 second the daemon is terminated by AMCD using either:
/opt/amc/script/rmd stop

or 

/opt/amc/script/sipd stop
  • 5 seconds later the deamon is restarted by AMCD using:
/opt/amc/script/rmd start

or 

/opt/amc/script/sipd start
  • If no new idle frame is received from the daemon within 30 second the stop/start procedure is repeated, this sequence will be repeated 5 times.


Example of Syslog AlphaLog report for this sequence: 

W(204.65) INFO_DP_LINK_DOWN, no:337  "" P1: 31, P2: 150, P3: 0 DP link down, port 31  node 150 device 0
W(204.65) UNEXP_SIG, no:338  "sipd start" P1: 31, P2: 0, P3: 0 
W(204.65) INFO_DP_IDLE_FRAME, no:339  "" P1: 31, P2: 150, P3: 0 Peer on ACDP port 31 is node 150 device 0
