1.3.1
IP Related System Message and Its Reason (33-R)
About System Message “33-R” Outputted From IPPAD Circuit Card
(1) FNC=05H (Sequence error), INF=01/02H, FLT=xxH is outputted.
Fault reason
•
Trouble during circuit card (IPPAD) initialization
•
Trouble during registration process of IP station
<
(a) Confirm all circuit card and IP stations are operating normally.
(b) If all operation is normal, accept it as an impulsive error and continue monitoring. When not activating
normally, change the circuit card (in case of IPPAD). Contact NEC maintenance personnel when prob-
lem is still not solved after performing this procedure.
About System Message “33-R” Outputted Only from IPPAD Circuit Card
(1) FNC=03H, INF=01H, FLT=02H (Excessive RTP packet loss) is outputted
Fault reason
•
When packet loss has occurred
•
When voice data suddenly cut or muted.
•
Circuit card fault (IPPAD)
<
Hardware fault or network problem might be the reason, thus system will notice there was a impulsive
problem processing the voice data.
(a) Verify the System Message and faulty part when voice data is suddenly cut off or muted.
(b) Contact the network administrator or confirm each network equipment when this fault occurs fre-
quently.
