Parameter Description
System dependability (DEP-S) and call processing (VT) send error messages and advisories to signalling task (SIT). The SIT converts these messages from binary to ASCII format and distributes them as signalling messages (SIM) to defined output devices.
These signalling messages can be selected and can be suppressed. The information required for this is located in the database ADS in tables SDT (signalling distribution table) and FET (error element table) - see Diagnostics Service Manual A30950-S1-X301-*-7620.
The tasks of the AMO-SIGNL (signalling control) are as follows:
1.
to manipulate the message signalling, i.e., whether messages are to be signaled and if so, to which symbolic devices;
2.
to regenerate the data administered by the AMO-SIGNL;
3.
to output an SIT-internal error statistics table and to erase it;
4.
to cancel the alarm memory (AL) in the attendant console task (see SHB Volume ’Dependability’).
5.
to administer the error element special table (FST) (SIT table for controlling the priority of messages depending on the action involved).
6.
to activate and deactivate certain items to controlling message output. These are
- IMPTMSG (forced output of important messages, replaces the former F1000)
- FILTER (only restart messages and special events)
- ALLMSG (all messages to this device)
- SHORTFM (short message)
7.
To handle user defined text
8.
to display system data
state of SWU
state of ADP
state of ref clock
state of trunk failure switchover
alarms

Definitions
An edited signalling message (SIM) consists of a header line and optional supplementary lines in accordance with the section ’Format of the Output Message’ in Volume ’Dependability’. An example is shown below.
The components of the header line are as follows:
1.
Message identification (MID) with code CD (1 digit) and message number NO;
2.
Priority for remote operation CD (2 digits) and number (1 digit);
3.
serial number of message
4.
Action;
5.
Originator module;
6.
Error class (EVT), F1 field;
7.
Error (SUBEVENT), F2 field;
8.
Date;
9.
Time of day.
The components 4, 5,6 and 7 are contained in the received message and are edited using text tables.
The components 1,2 and 3 are added by SIT via the SDT from the FET.
For each signalling message class, the following are defined in SDT:
•
EVT_STATE
:
For evaluation of EVT signalling
SEV_TYPE
:
For evaluation of SUB-EVT
E_M_IDX
:
Error class mask index
FE_NUM
:
Number of error elements of EVT
FET_IDX
:
Start index of EVT in the error element table.
For each signalling message, i.e., for error elements (RS_SUB_EVT), within a message class the following are defined in FET (DA_S_ST_FET_ARRAY):
•
S_FREE
:
Identifier for signalling the error element
•
MSG_ID_KEY
:
Code for message identification
’A’ alarm
’F’ error
’M’ advisory
’U’ undefined error element
•
MSG_ID_NO
:
Number of MSG_ID in the range of 1000 - 9999
•
AFR_PRIO
:
Priority for AFR (consisting of code (CD) and number (NO))
’E’ Unambiguous error (error with single implication)
’M’ Ambiguous error (error with multiple implications)
’1’-’9’ Priority
•
DEV_ACT
:
Current symbolic devices for SIM output
•
DEV_KONF
:
Configured symbolic devices
S_M_IDX
:
SEV/error text masks IDX for field F2 of SIM header line
The components marked with ’•’ can be manipulated by the AMO.
The edited SIM are output to defined logical devices to which corresponding physical devices are assigned.
Following are the symbolic devices of SIT:
DPT1
Data processing terminal
DPT2
Printer
DPT3
Not used (e.g., spare for filetask)
DPT4
HISTO file
NDP4
No output to DPT4 for given MID
ATND
Attendant console (ATND)
AFR
Remote operation
MAP
Maintenance and alarm panel.
SICO
signalling control
AFR1
automatic fault report (multiple destination 1)
AFR2
automatic fault report (multiple destination 2)
AFR3
automatic fault report (multiple destination 3)
Note
The MAP receives only the component ZUSTAND (state) of the received error message or advisory from SIT.

Table for user defined texts (FMTEXT)
This is a table with 30 entries for user defined text per message id (Fxxxx). Each element consists of
•
MSG_ID_KEY
:
Code for message identification only ’F’ allowed
•
MSG_ID_NO
:
Number of the MSG_ID in the range from 1000 - 9999
•

This is a table for the following switch functions (see below)
•

Error Element Special Table (FST)
For certain error numbers, it is necessary to ascertain the priorities (important for remote operations) on the basis of the action in question. For this purpose, a local table of signalling tasks (SIT) exists, the administration of which is carried out by the AMO-SIGNL.
Each element (DA_M_ST_FE_STAB_ELEM_STR) of the FST (DAD_S_ST_FE_STAB) contains the following components:
•
MSG_ID_NO
:

•
