Error Code Alarm Level Description
Stream Continuity
Error
MINOR Transport stream received by descrambler module has lost
one or more packages (is superseded by High Continuity
Error Rate)
Software download in
progress
NOTIFY Software is being downloaded to the specified descrambler.
SW/HW mismatch MAJOR The HW platform used by the descrambler is also used for
the Decoder and Scrambler cards. During boot an option file
is scanned which tells the card what it is. If the card is told it
is a decoder, but detects that it is the descrambler software
running then this SW/HW mismatch alarm is raised.
Component map
overflow
MINOR The number of pids mapped through the Descrambler has
exceeded the capacity of the card. Try to remove some
service pids.
No CAM CRITICAL CAM module is missing or not responding
CAM communication
error
CRITICAL Error in communication with CAM module.
Currently not in use.
Descrambling failure CRITICAL Descrambler unable to descramble selected service. Please
check that smartcard has access to service.
Bad backplane frame MAJOR Data received were corrupt from the backplane. If this
happens in large number hardware should be investigated.
CAM Reset by operator Information The CAM module has been reset by the operator.
C.6 Scrambler & SCS Module
The scrambler card consists of two software modules: The Scrambler and the SCS.
Most of the alarms from the SCS module is Simulcrypt related, and thus have error
codes from the CA system. Hence the below alarms are general alarms which will
contain more specific information upon triggering of the alarm.
Error Code Alarm Level Description
Transport stream
missing
CRITICAL The scrambler module is not receiving configured transport
stream
Bad backplane frame MAJOR An invalid IP frame arrived at the IP interface on the
backplane.
Missing SCG Update The scrambler expects regular updates of control words. Ths
alarm indicates that more than 60 seconds has elapsed
since the last CW arrived.
This could be the case if the communication towards the CA
system has failed.
SCG Update Late MAJOR A Control Word arrived, but the playout starting point has
already elapsed.
EMM Stream Warnings MINOR EMM stream alarms reported by the CA System. The alarm
description will provide the alarm actually reported by the
CA system.
Major Channel Errors MAJOR A MAJOR Simulcrypt channel alarm.
Major Stream Errors MAJOR A MAJOR Simulcrypt stream alarm
Critical Channel Errors CRITICAL A Critical Simulcrypt channel alarm
Critical Stream Errors CRITICAL A Critical Simulcrypt stream alarm
EMMG Critical Channel
Errors
CRITICAL A Critical Simulcrypt EMM channel alarms
EMM Critical Stream
Errors
CRITICAL A Critical Simulcrypt EMM stream alarms.
C.7 ASI Input Module
Error Code Alarm Level Description
No synch CRITICAL No ASI input synch detected
Input buffer overflow.
Packet dropped.
CRITICAL Transport stream input buffer is overflowing. Packages are
dropped.
In the rare cases when this happens it is usually due to a
configuration where one service has been used for multiple
outputs. The input card is able to copy services in this manner
but at some point the copy process will be too time consuming
which causes input packets to be lost.
