alcCuSvcMsgHeaderThe is is the header that is sent out whenever the protocol module
determines the need to send a service message. This prefix is in the
native character set of the protocol. If the value of alcCuSvcMsgIndex
is non-zero, then the prefix will be sent followed by the appropriate message
followed by the trailer.
Typically this header will be:
<IA><broadcast TA><CMD1><CMD2>
If applicable, the header must include the column and row
number where the message must appear.rw DisplayString .1.3.6.1.4.1.1978.2.10.1.3.1.22 |
alcCuSvcMsgIndexThis provides the index into the service message table: 'svcmsgTable'.
If this index is non-zero, the protocol (when it determines a message is required)
will send the alcCuSvcMsgHeader followed by the appropriate message from this
row in the svcmsgTable, followed by the alcCuSvcMsgTrailer.
Both the header and the trailer are in the native character set of the protocol.
However it is the responsibility of the protocol module to translate the
text of the actual message into the native character set before transmission.rw INTEGER .1.3.6.1.4.1.1978.2.10.1.3.1.23 |
alcCuSvcMsgTrailerThis is the trailer sent whenever a service message is sent.
It is in the native character set of the protocol.
It is only used if the value of alcCuSvcMsgIndex is non-zero.
It will typically be: <EOMc>rw DisplayString .1.3.6.1.4.1.1978.2.10.1.3.1.24 |

when the CU's status (alcCuStatus) changes to enabled-up,
and enabled-down respectively.rw Enumeration .1.3.6.1.4.1.1978.2.10.1.3.1.30 |
alcCuDroppedA count of the number of messages dropped due message sent
which is not being acknowledged by the CU.ro Counter .1.3.6.1.4.1.1978.2.10.1.3.1.31 |
