This document describes the function of the NOP Subsystem.
1.1 I̲N̲T̲R̲O̲D̲U̲C̲T̲I̲O̲N̲
The purpose of the NOP is to generate control message
to be released in the FIKS network when an event occurs.
1.2 A̲B̲B̲R̲E̲V̲I̲A̲T̲I̲O̲N̲S̲

3.1 F̲U̲N̲C̲T̲I̲O̲N̲A̲L̲ ̲C̲A̲P̲A̲B̲I̲L̲I̲T̲I̲E̲S̲
3.1.1 N̲O̲P̲ ̲M̲a̲i̲n̲
When a MTCB containing an event is inserted in the
NOP input queue, the NOP will generate a control message
and release it to the output queue. In this way the
NOP will generate all control messages from the SCC
to the rest of the network except from the 24-hour
MEDE-statistic.
When information is needed except from those in the
MTCB they will be read in the regions:
- FST
- FRT
- FNC
- TABUPD
3.1.2 G̲E̲T̲ ̲C̲A̲S̲E̲
The GET ̲CASE procedure will determine which event has
been queued to the NOP. It will look up the MTCB to
see the event type.
3.1.3 G̲E̲T̲ ̲C̲M̲P̲A̲R̲S̲
The GET ̲CMPARS procedure will build the data body of
the control message according to the event type. The
control message will be written to file if needed.
3.1.4 C̲M̲ ̲G̲E̲N̲
The CM ̲GEN procedure will build a control message with
a binary header and a data body.
The MTCB pointing to the control message is created
and updated.
The control message is queued for output.
3.1.5 P̲M̲T̲C̲B̲ ̲G̲E̲N̲
The PMTCB ̲GEN procedure generates a MTCB containing
a ISH- or NTS-command. The MTCB is queued for output.
3.1.6 G̲E̲T̲ ̲O̲R̲I̲G̲
The GET ̲ORIG procedure reads the OWN ̲ID (i.e. the id
of current SCC) in the FST region.
3.1.7 G̲E̲T̲ ̲S̲C̲C̲ ̲S̲T̲
The GET ̲SCC ̲ST procedure reads the status of the two
SCC's in the FST region.
3.1.8 G̲E̲T̲ ̲S̲E̲Q̲N̲O̲
The GET ̲SEQNO procedure reads a sequence number in
the FST region. The number must be used in ISH- and
NTS command control messages. The sequence number
in the FST region is incremented.
3.1.9 G̲E̲T̲ ̲N̲N̲ ̲I̲D̲ ̲T̲R̲
The GET ̲NN ̲ID ̲TR procedure returns the neighbour node
id from a node id and a trunk No. The information
is read in the FNC region.
3.1.10 G̲E̲T̲ ̲R̲O̲U̲T̲M̲
The GET ̲ROUTM procedure will return a routing mask
to be used in the control message. The mask is generated
in accordance with the type of control message in which
it shall be used.
3.1.11 G̲E̲T̲ ̲R̲E̲L̲ ̲D̲T̲G̲
The GET ̲REL ̲DTG procedure reads the system time. The
time will be used for indicating the create time for
the control message.
3.1.12 G̲E̲T̲ ̲A̲I̲G̲ ̲P̲A̲R̲S̲
The GET ̲AIG ̲PARS procedure will update the MTCB category
according to the requested type of AIG update. The
AIG update is written to file.
3.1.13 G̲E̲T̲ ̲A̲N̲O̲ ̲P̲A̲R̲S̲
The GET ̲ANO ̲PARS procedure will update the MTCB category
according to the requested type of ANO update. The
ANO update is written to file.
3.1.14 G̲E̲T̲ ̲U̲S̲P̲ ̲P̲A̲R̲S̲
The GET ̲USP ̲PARS procedure will update the MTCB category
according to the requested type of USP update. The
USP update is written to file.
3.1.15 G̲E̲T̲ ̲R̲O̲U̲T̲ ̲P̲A̲R̲S̲
The GET ̲ROUT ̲PARS procedure will generate the routing
table for the requested node/mede. The routing table
is extracted from the FRT region. The routing table
is written to file.
3.1.16 C̲R̲E̲ ̲S̲E̲Q̲ ̲T̲A̲B̲
The CRE ̲SEQ ̲TAB procedure will generate a table telling
in which order the routing tables has to be released
to the network. This is done to assure that all routing
tables are distributed correctly.
3.1.17 M̲T̲C̲B̲M̲I̲N̲I̲T̲
The MTCBMINIT procedure will identify the NOP for the
MTCB Monitor and get file descriptors to the system
volumes.

the created MTCB.
3.1.24 G̲E̲T̲-̲T̲A̲-̲P̲A̲R̲S̲

according to the requested type of TA-update. The TA-update
is written to the file containing the control-
message to be transmitted to the network
