4.2.3.1.1 I̲n̲t̲r̲o̲d̲u̲c̲t̲i̲o̲n̲
The transport subpackage (TRS) supplies the functions
which are necessary to initialize a specified Transport
Process. Furthermore it includes a number of auxiliary
functions common to different parts of the Process.
The description of the Transport Subpackage also serves
the purpose of giving an overview of a Transport Process
concerning Software Structure, Internal Communication
and Data Structure.
4.2.3.1.2 T̲r̲a̲n̲s̲p̲o̲r̲t̲ ̲P̲r̲o̲c̲e̲s̲s̲
This section introduces the functions which support
a Transport Process within CAMPS.
Six types of Transport Processes are realized:
- TRC/POINT TO POINT
- NICS/TARE
- SCARS/CCIS
- PTR
- PTP
- OCR
The functional breakdown for each type of process is
depicted on figure 4.2.3.1.2-1.
Four main groups of functions have been identified:
- Transport Initialization
- Transport Control
- Outgoing Transport
- Incoming Transport
4.2.3.1.3 T̲r̲a̲n̲s̲p̲o̲r̲t̲ ̲I̲n̲i̲t̲i̲a̲l̲i̲z̲a̲t̲i̲o̲n̲
When a Transport Process is created, the type of transport
and the number of channels/devices to be controlled
must be specified to the process.
The Transport Initialization includes all functions
which are necessary to initialize Transport Control,
Outgoing Transport and Incoming Transport in such a
way that they support the specified type of transport.
4.2.3.1.4 T̲r̲a̲n̲s̲p̲o̲r̲t̲ ̲C̲o̲n̲t̲r̲o̲l̲
The Transport Control takes care of the superior control
functions concerning the outgoing and incoming transport.
(START ̲UP, CLOSE ̲DOWN, Timer Functions etc.)
The functions performed by Transport Control are initiated
by commands received from external subpackages through
a Channel Command Queue (CCQ).
Each channel/device within a Transport Process has
its own Transport Control working independently of
the others.
The Transport Control has its own subpackage "Transport
Control Subpackage" (Ref. 4.2.4), which supplies a
detailed functional description
4.2.3.1.5 I̲n̲c̲o̲m̲i̲n̲g̲ ̲T̲r̲a̲n̲s̲p̲o̲r̲t̲
The Incoming Transport includes the functions which
transfer the messages from IOS to the Analysis Processes.
A number of message lines are detected in order to
separate the message into the field groups which constitute
the External Message Format of a CIF.
Furthermore a number of error checks are performed.
Parameters describing the message are collected and
transferred to the Analysis together with the result
of the error check.
Each channel/device within a Transport Process has
its own Incoming Transport working independently of
the others.
The Incoming Transport has its own subpackage "Incoming
Transport Subpackage" (sec. 4.2.5) which gives a detailed
description of the functions for each type of Transport.
4.2.3.1.6 O̲u̲t̲g̲o̲i̲n̲g̲ ̲T̲r̲a̲n̲s̲p̲o̲r̲t̲
The Outgoing Transport includes the functions which
are closely related to the outgoing traffic.
Outgoing messages are received from the circuit queue
related to the subprocess and transferred to the IOS
for transmission to the external line/device.
The Outgoing Transport appends a number of lines such
as: start of message, text separators, end of message,
page identification etc. (ref. sec. 4.2.6).
The OTS may also generate and transmit Abbreviated
Service Messages (ASM) specified by the Transport Control.
The Outgoing Transport has its own subpackage "Outgoing
Transport Subpackage" (sec.4.2.6) which gives a detailed
functional description.
TRANSPORT PROCESS Figure 4.2.3.1.2-1
4.2.3.2 S̲o̲f̲t̲w̲a̲r̲e̲ ̲S̲t̲r̲u̲c̲t̲u̲r̲e̲
The basic unit in a Transport Process is a subprocess
taking care of all functions related to an external
channel or a stand alone devices (PTP/PTR/OCR).
When a Transport Process has been created it will start
up a subprocess for each channel/device which is to
be controlled by the process.
This section describes the principle software structure
related to a Transport Process. The basic components
of the software structure are shown on figure 4.2.3.2-1
to 4.2.3.2-6.
All functions within a Transport Subprocess are realized
by means of coroutines running under control of the
CSF Coroutine Monitor.
The software is supplied with a specific set of coroutines
for each type of Transport Process. During the initialization
of a Transport Process only the set of coroutines related
to the actual type of Transport is presented to the
Coroutine Monitor.
Each coroutine is constructed as a reentrant procedure.
This makes it possible for all subprocess within a
Transport Process to share the same code minimizing
the resources of memory.
4.2.3.2.1 T̲r̲a̲n̲s̲p̲o̲r̲t̲ ̲I̲n̲i̲t̲
The purpose of the Transport Init module is to initialize
a Transport Process with the number of subprocesses
prescribed by the creating process, i.e. the "Parent
Process".
The initializing includes the following main tasks:
a) Init. of the data structure for each subprocess.
b) Setting up each subprocess with the coroutines
specific for the type of process to let them run
under control of the Coroutine Monitor.
c) Starting up the Coroutine Monitor.
4.2.3.2.2 T̲r̲a̲n̲s̲p̲o̲r̲t̲ ̲A̲u̲x̲i̲l̲i̲a̲r̲y̲ ̲F̲u̲n̲c̲t̲i̲o̲n̲s̲
The Transport Auxiliary Functions include a number
of procedures which are common to the Transport Control,
Outgoing Transport and Incoming Transport.
4.2.3.2.3 T̲r̲a̲n̲s̲p̲o̲r̲t̲ ̲C̲o̲n̲t̲r̲o̲l̲ ̲C̲o̲r̲o̲u̲t̲i̲n̲e̲.̲
The Transport Control Coroutine is responsible for
all functions related to the Transport Control of a
single Transport Subprocess. A specific Transport Control
Coroutine is supplied for each type of Transport.
Each of these coroutines is described in the Transport
Control Subpackage (see section 4.2.4).
4.2.3.2.4 O̲u̲t̲g̲o̲i̲n̲g̲ ̲T̲r̲a̲n̲s̲p̲o̲r̲t̲ ̲C̲o̲r̲o̲u̲t̲i̲n̲e̲
The Outgoing Transport Coroutine is responsible for
all functions related to the outgoing transport of
a single Transport Subprocess. A specific Outgoing
Transport Coroutine is supplied for each type of transport
except for the PTR and the OCR.
Each of these coroutines is described in the Outgoing
Transport Subpackage (see section 4.2.6).
4.2.3.2.5 I̲n̲c̲o̲m̲i̲n̲g̲ ̲T̲r̲a̲n̲s̲p̲o̲r̲t̲ ̲C̲o̲r̲o̲u̲t̲i̲n̲e̲
The Incoming Transport Coroutine is responsible for
all functions related to the incoming transport of
a single Transport Subprocess. A specific Incoming
Transport Coroutine is supplied for each type of transport
except for the PTP.
Each of these coroutines is described in the Incoming
Transport Subpackage (see section 4.2.5).
4.2.3.2.6 S̲u̲b̲p̲r̲o̲c̲e̲s̲s̲ ̲D̲a̲t̲a̲ ̲R̲e̲c̲o̲r̲d̲
The Subprocess Data Record defines all data structures
necessary to support the coroutines within a subprocess.
The Transport Subprocess Data Module includes definition
of a specific data record for each type of Transport
(see section 4.2.3.5).
All Data Records within a Transport Process is initialized
by the Transport Init module.

4.2.3.3.1 D̲y̲n̲a̲m̲i̲c̲a̲l̲ ̲P̲r̲o̲g̲r̲a̲m̲ ̲S̲t̲r̲u̲c̲t̲u̲r̲e̲
When a transport process is created it will first execute
the procedures supplied by the Transport Init module.
Hereby the process is divided into a number of subprocesses
corresponding the number of channels/devices, which
are to be controlled by the process.
For each subprocess a specific number of coroutines
are presented to the Coroutine Monitor (i.e. inserted
in the Ready List).
When the Transport Init procedures are all executed
the program control is handed over to the Coroutine
Monitor. From now on all coroutines within the process
are executed in the order they appear in the Ready
List of the Coroutine Monitor.
The coroutines within a subprocess exchange information
to synchronize the transport (ref. 4.2.3.3.2). Note
however that the subprocesses within a transport process
is independent of each other.
4.2.3.3.2 I̲n̲t̲e̲r̲n̲a̲l̲ ̲C̲o̲m̲m̲u̲n̲i̲c̲a̲t̲i̲o̲n̲
The communication logic within a Transport Subprocess
is realized by means of semaphores through which the
coroutines exchange operations.
To create a Transport Subprocess three semaphores have
been introduced with the following type definitions:
Type TC ̲OPSEM: COROUTINE ̲SEMAPHORE
OT ̲OPSEM: COROUTINE ̲SEMAPHORE
IT ̲OPSEM: COROUTINE ̲SEMAPHORE
The configurations of semaphores and coroutines are
shown on figure 4.2.3.3.-1 to 4.2.3.3.-6 for each type
of Transport Subprocess.
Send and receive functions related to semaphores are
performed by means of procedures defined within the
CSF Coroutine Monitor.
A detailed description of semaphore operations for
all types of Transport Subprocesses is given in section
4.2.3.7.
4.2.3.3.2.1 T̲r̲a̲n̲s̲p̲o̲r̲t̲ ̲C̲o̲n̲t̲r̲o̲l̲ ̲O̲p̲e̲r̲a̲t̲i̲o̲n̲ ̲S̲e̲m̲a̲p̲h̲o̲r̲e̲,̲ ̲T̲C̲ ̲O̲P̲S̲E̲M̲
̲
The main waiting point for the Transport Control Coroutine
(TC ̲COROUTINE) is the TC ̲OPSEM semaphore.
From here the TC ̲COROUTINE may receive operations from
the Outgoing Transport Coroutine (OT ̲COROUTINE) or
the Incoming Transport Coroutine (IT ̲COROUTINE).
Commands from the Channel Command Queue (CCQ) are
also received through the TC ̲OPSEM. In this case the
TC ̲COROUTINE first initiates a System Call
(RECEIVE ̲FIRST ̲QEL) and then associates the answer
to the TC ̲OPSEM.
When a command is available in the CCQ an operation
is sent to the TC ̲OPSEM telling the TC-COROUTINE that
a command is ready.
4.2.3.3.2.2 O̲u̲t̲g̲o̲i̲n̲g̲ ̲T̲r̲a̲n̲s̲p̲o̲r̲t̲ ̲O̲p̲e̲r̲a̲t̲i̲o̲n̲ ̲S̲e̲m̲a̲p̲h̲o̲r̲e̲,̲ ̲O̲T̲ ̲O̲P̲S̲E̲M̲
̲
The main waiting point for the Outgoing Transport Coroutine
(OT ̲COROUTINE) is the OT ̲OPSEM semaphore.
From here the OT ̲COROUTINE may receive operations from
the Transport Control Coroutine (TC ̲COROUTINE). This
makes it possible for the TC ̲COROUTINE to interfere
with the outgoing transport.
The outgoing messages to be transmitted on the external
channel are received from the circuit Queue (CIQ) through
the OT ̲OPSEM. In this case the OT ̲COROUTINE first initiates
a System Call (RECEIVE ̲FIRST ̲QEL) and then associates
the answer to OT ̲OPSEM.
When a message is available in the CIQ an operation
is sent to OT ̲OPSEM indicating that a message is ready
for transmission.
The OT ̲COROUTINE will pack the message lines into a
buffer which is sent to the IOS for outgoing transmission.
This is done by initiating a System Call (APPEND ̲BYTES)
and associating the answer to OT ̲OPSEM.
When the IOS has emptied the buffer an operation is
sent to OT ̲OPSEM telling the OT ̲COROUTINE that the
buffer is idle.
4.2.3.3.2.3 I̲n̲c̲o̲m̲i̲n̲g̲ ̲T̲r̲a̲n̲s̲p̲o̲r̲t̲ ̲O̲p̲e̲r̲a̲t̲i̲o̲n̲ ̲S̲e̲m̲a̲p̲h̲o̲r̲e̲,̲ ̲I̲T̲ ̲O̲P̲S̲E̲M̲
The main waiting point for the Incoming Transport Coroutine
(IT ̲COROUTINE) is the IT ̲OPSEM semaphore.
From here the IT ̲COROUTINE may receive commands from
the Transport Control Coroutine (TC ̲COROUTINE). This
makes it possible for the TC ̲COROUTINE to interfere
with the incoming transport.
The incoming messages from the IOS are also received
through IT ̲OPSEM. In this case the IT ̲COROUTINE initiates
a System Call (READ ̲BYTES) and associates the answer
to IT ̲OPSEM.
When the IOS has filled out a buffer with characters
from the external line, an operation will be sent to
IT ̲OPSEM, telling the IT ̲COROUTINE that the buffer
is ready.
4.2.3.3.2.4 T̲r̲a̲n̲s̲p̲o̲r̲t̲ ̲S̲u̲b̲p̲r̲o̲c̲e̲s̲s̲ ̲O̲p̲e̲r̲a̲t̲i̲o̲n̲ ̲P̲o̲o̲l̲s̲
A transport subprocess is supplied with a specified
maximum of operations by means of which the internal
communication takes place.
The TRS ̲OP ̲POOL semaphore contains those of the operations
which at a certain moment are not being used in the
internal communication, i.e. the idle operations.
A coroutine takes out (receives) an idle operation
from the TRS ̲OP ̲POOL each time a message is to be sent
to another coroutine
An operation received from another coroutine is returned
to the TRS ̲OP ̲POOL when the information has been saved
or decoded.
Operations used for communication with IOS are stored
in IOC ̲OUT ̲POOL and IOC ̲INP ̲POOL. These operations
are connected to a specific buffer structure required
for transmitting/receiving a message through IOS. The
pools simplify the reservation of buffer structures.
The pools mentioned above are initialized with operations
by the Transport Init Module.

The Transport Init Module is called from the main module
"TRANSPORT" which contains the first statement to be
executed when a Transport Process has been created.
The Transport Init Module will initialize a Transport
Process with the type of transport(s) which are specified
by the "Parent Process" (i.e. COPSY).
The following main tasks are included:
a) Setting up a data record for each subprocess within
the process. (See figure 4.2.3.5.1-1).
The subprocess data record for each type of transport
is defined in sec. 4.2.3.5.
b) Presenting a coroutine description to CSF Coroutine
Monitor for each coroutine within a subprocess.
c) Handing over the running of coroutines to the Coroutine
Monitor.

The data area for a Transport Process may be divided
into two main parts (see figure 4.2.3.5.1-1).
a) C̲o̲m̲m̲o̲n̲ ̲P̲r̲o̲c̲e̲s̲s̲ ̲D̲a̲t̲a̲
Contains variables, constants and strings declared
within the program modules for a transport process.
This area is common to all subprocesses within the
process and has the same structure for all types
of transport.
b) Array of subprocess data records defined for the
type of transport which are to be controlled by
the process.
XX ̲PROC ̲DATA ARRAY (1..MAX ̲XX ̲PR ̲PROCESS) OF
TRS ̲XX ̲DATA
with TRS ̲XX ̲DATA equal to one of the following data
records:
TRS ̲TP ̲DATA : (TRC/P TO P)
TRS ̲NT ̲DATA : (NICS TARE)
TRS ̲SC ̲DATA : (SCARS/CCIS)
TRS ̲PTP ̲DATA : (PTP)
TRS ̲PTR ̲DATA : (PTR)
TRS ̲OCR ̲DATA : (OCR)
All data records include the entry "TRANSPORT PARAMETERS".
The other fields are of different type from record
to record.
The TRANSPORT PARAMETERS are initialized with reference
to the other fields of the data record.
All coroutines within a transport subprocess are reentrant
and access the data record by impressing the TRANSPORT
PARAMETERS on a specific address inserted into the
Coroutine Descriptions during the initialization.
When a coroutine is active, the address of its Coroutine
Description is stored into the external variable "RUNNING
COROUTINE" which is updated by CSF Coroutine Monitor.
(ref.fig.4.2.3.7.1-1).

The communication within a Transport Subprocess is
realized by means of semaphores through which the coroutines
exchange information.
The information is stored in operations with a data
structure as defined in section 4.2.3.5.7.2.
The principle flow of operations is described in section
4.2.3.3.2, which defines the semaphores within a Transport
Subprocess.
The types of operations within a Transport Subprocess
is defined in section 4.2.3.5.11.1.
The operation type "IOC ̲REPLY" is related to a special
data structure necessary for communication with IOC
(ref. 4.2.3.5.7.3).
The following tables defines the operations which may
occur within each type of Transport Process.
SEMAPHORE OPERATIONS FOR:
TRC/PTOP TRANSPORT SUBPROCESS
