AlphaCom supervision of protocol converter daemons

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

SIPD is connected to ACDP port 31
RMD is connected to ACDP port 32 

• 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:

/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_IDLE_FRAME, no:339  "" P1: 31, P2: 150, P3: 0 Peer on ACDP port 31 is node 150 device 0
