This document specifies the M̲S̲A̲ ̲(̲M̲e̲s̲s̲a̲g̲e̲-̲c̲o̲n̲v̲e̲r̲s̲i̲o̲n̲
̲f̲r̲o̲m̲ ̲S̲M̲F̲ ̲t̲o̲ ̲A̲C̲P̲-̲1̲2̲7̲) within the FIKS application software.
The design is based on issue 5 of the Requirements
Specifications.
The main tasks of the MSA are:
- to perform internal conversion, i.e. to convert
FIKS messages from the SMF to the ACP-127 format,
- to perform external conversion, i.e. to convert
FIKS generated messages for NICS/TARE from the
SMF to the ACP-127 format,
- to put SMF messages, for which conversion is not
possible, into the queue for interception.

3.1 F̲U̲N̲C̲T̲I̲O̲N̲A̲L̲ ̲C̲A̲P̲A̲B̲I̲L̲I̲T̲I̲E̲S̲
Messages for conversion are put into the Conversion
Queue (CQ): into CQ2 for internal conversion, or into
CQ4 for external conversion.
Internal conversion means that the converted message
is returned to the FIKS originator. Such messages are
stored in the Node-Mede Queue (NMQ) after conversion.
External conversion means that the converted message
is forwarded to NICS-TARE. These messages are put into
the NICS-TARE Queue (NTQ) before transmission.
Input messages are formated according to the SMF format.
The format of output messages is the ACP-127 format.
Internal converted messages, however, are put into
an SMF envelope due to the transmission throughout
the …02…FIKS network.
Messages, which cannot be converted, are put into the
CIP IC input Queue (CICQ) for interception.
The functional grouping of the MSA is shown in figure
3.1-1.
The SMF message format is shown in figure 3.1-2.
The ACP-127 message format is shown in figure 3.1-3.
When conversion is completed a conversion logging is
performed. For details, see section 2, Applicable Documents
reference 9.
If a ZPW Operating Signal is present in a message which
is sent for conversion, then the ZPW will be inserted
in Format Line 5 of the ACP127 message after the message
DTG e.g.
R 011025Z JUL 88 ZPW 041400Z JUL 88
If a message for conversion is retransmitted (by RTM)
then the Operating Signal (ZDK, ZFG or ZFD) will be
inserted in Format Line 5 of the ACP127 message after
the message DTG, or if a ZPW is present, then it will
be inserted after the ZPW DTG e.g.
R 011025Z JUL 88 ZDK
R 011025Z JUL 88 ZPW 041400Z JUL 88 ZDK
3.2 I̲N̲T̲E̲R̲F̲A̲C̲E̲ ̲D̲E̲S̲C̲R̲I̲P̲T̲I̲O̲N̲
The CIP process receives a message from the SIP process
on the collocated N/M via the trans connection, which
is handled by the NSS process.
The CIP process enqueues an MTCB in the proper conversion
queue by call of the monitor procedure QACCESS.
The QACCESS sends a signal to the MSA process.
The MSA process will try to convert the message:
if succeeded: enqueue an MTCB (pointer to the converted
message) in the proper output queue,
if failed: enqueue an MTCB (pointer to the original
message) in the intercept queue.
3.3 P̲R̲O̲C̲E̲S̲S̲I̲N̲G̲
3.3.1 T̲h̲e̲ ̲M̲o̲d̲u̲l̲e̲s̲
The MSA consists of a main program and a number of
procedures. They are all ordered in a hierachical way.
All procedures are called by use of an index tabel
for details, refer to source list of JMPI ̲DECL.S. An
overview of the main program and the procedures is
given in figure 3.3-1.

3.3.1.0.1 M̲a̲i̲n̲ ̲P̲r̲o̲g̲r̲a̲m̲ ̲S̲M̲F̲-̲A̲C̲P̲
The SMF-ACP main program performs (See fig. 3.3-1(0.1A-D)):
Call WAITEVENT: wait for signal (from QACCESS: message
for conversion).
REPEAT:

goto WAITEVENT and wait for signal.
Call MTCB, RESERVE.
Call MTCB, GETFILE, for update of FILE ̲REF (ref. to
file on IMF) and FD-SMF (file descriptor).
Call QACCESS for deletion of element.
Call MTCB, READ, lookup conversion type (internal or
external), and update of INTERN ̲FLAG.
Call MTCB CREAT and CREATEFILE, for creation of 3 MTCB's

in FILE ̲SA).
Call proc. BUILD ̲FL6, for building format line 6 (written
in FILE ̲SA).
Write FILE ̲TO into FILE ̲SA (format line 7 and 8) by
calling proc. SA ̲FILE ̲TO ̲FILE.
Write FILE ̲XMT into FILE ̲SA (format line 9), by call
of proc. SA ̲FILE TO FILE.
Call MTCB, RELEASEFILE and RELEAS for release of 2
MTCB's and FILE's ( ̲TO and ̲XMT).
Call MTCB, CREAT and CREATEFILE, for creation of MTCB
and FILE ̲ACP, in which the ACP-message is delivered.
Call proc. WRITE ̲FILE, for appending "BT" to FILE ̲SA.
Call proc. BUILD ̲FL12A, for building format line 12A
(written FILE ̲SA).
Call proc. BUILD ̲FL12B, for building format line 12B
(written in FILE ̲SA).

The MSG ID of the converted message will be (Q/P)SA.
If it is an external conversion and MANUEL = TRUE,
then the MSG ID of the converted message will be (Q/P)FN.
The envelope is stored in the SA buffer, and finally
written into the ACP file.

spaces are skipped, so that the index of the SMF buffer
now points to the start of the plaintext of the adressee;
also the number of remaining characters of the line
is calculated.

This procedure updates ANO and AIG bitmaps.
ANO-bitmap: Contains a bit for each NATO-ANO.
INPUT/OUTPUT: A NATO-ANO: lookup the bitmap:
IF bit = 0 THEN SET bit and set WRITE
̲ANO = true.
IF bit = 1 THEN SET WRITE ̲ANO = false.
AIG-bitmap: The bitmap delivered by RDF-monitor.
INPUT/OUTPUT: an XMT: release bit (set bit = 0) in
AIG-bitmap.
The functions are described below:
Reset variable WRITE ̲ANO.
Split input ANO into ID and number.
Test on ID and set offset in bitmap.
IF ANO = conversion-ANO, THEN skip it.
DO lookup in bitmap, and set bit and WRITE-ANO according
to rule.
IF not a NATO-ANO then add 2 to ANO ̲TYPE:
TO ̲ANO becomes a MINUS - TO - ANO,
INFO ̲ANO becomes a MINUS - INFO - ANO.

the NICS-TARE Queue (NTQ).
The output queue for internal converted messages is
the Node/Mede Queue (NMQ).
Also pseudo-MTCB's for messages for interception are
put into the NMQ.

Preparation of the binary object code starts with an
editing of the source text.
Then the source file MSA.S, which includes all source
text, is compiled by running the SWELL compiler, and
the listing is printed.
The object code is then linked by the LINKER.
Finally the binary code may be installed.
Exact instructions may be obtained from the file "INFORMATION"
in the most recent ESP-directory of FIXLIB.
