a) X-net, local area Network
Four different units of the X-net are placed outside
the main computer room:
(i) The XTA-module
(X-net Terminal Adapter)
(ii) The XAB-module
(X-net Amplifier and Branching Unit)
(iii) The XCP/module
(X-net Communication Port)
(iv) The XCT-module
On fig. 3.1.2-1 is shown a detail from the X-net
installation.
The X-net bus cables are run in the metallic pipe
and branched off in the punction box to the XTA-box,
which includes the XTA-module.
The terminal is connected to the X-net by a signal
cable to the XTA-box.
The XAB-module is housed in a box, which is the
same size as the XTA-box and connected to the X-net
in the same way. However, this box has no terminal-connection.
The XCP- and the XCT-modules can be housed in the
same box, the XCP/CT-box. The XCP-module provides
the interface to the crypto-link to remote sub-
branches.
In the main net-end, the XCP/CT-box contains only
the XCP-module.
In the remote net-end, the XCP/CT-box contains
both modules, a X-net controller is required for
the remote subbranch.
The XCP/CT-box is lower than the XTA-box.

The XTA Box which is used when connecting a terminal
to the dualized X-net contains two XWOs (X-net
wall outlets), one XTA, a filtered CANNON DB 25s
connector and a power supply with power line filtering.

3.2.1 I̲n̲t̲r̲o̲d̲u̲c̲t̲i̲o̲n̲
In this section is provided a more detailed description
of the components of the Processing Units (PU's) in
the three Processing Elements (PE's) of the proposed
configuration.
The datasheet packages separately delivered (see list
of technical litterature, PART II, subpart A of this
proposal) gives further specifications and characteristics
on the modules and other items used as building elements
in the PU's.
For specifications and characteristics for the proposed
terminals and peripherals please refer to the separate-
ly delivered technical litterature.
3.2.2 F̲r̲o̲n̲t̲-̲E̲n̲d̲/̲B̲a̲c̲k̲-̲E̲n̲d̲ ̲P̲r̲o̲c̲e̲s̲s̲o̲r̲s̲
These processors are constructed based on CR80 system
elements.
3.2.2.1 C̲R̲8̲0̲ ̲G̲e̲n̲e̲r̲a̲l̲ ̲D̲e̲s̲c̲r̲i̲p̲t̲i̲o̲n̲
Front- and Back-End Processors are constructed by means
of the modular, fault-tolerant CR80 computer system
by use of various standard modules (Printed Circuit
Boards) organized in units which are interconnected
by galvanic isolated transfer buses structured as illustrated
below, and shortly described in the following.
FIG. 3.2.2.1-1
The CR80 system units are housed in 19" crates (Card
Magazine) for installation in standard 19" racks as
shown in FIG. 3.2.2.1-2.
FIG. 3.2.2.1-2…01……01…CR80 PROCESSOR UNIT & CHANNEL UNIT
3.2.2.1.1 T̲h̲e̲ ̲P̲r̲o̲c̲e̲s̲s̲o̲r̲ ̲U̲n̲i̲t̲s̲ ̲(̲P̲U̲)̲
The PU is a multiprogrammable multiprocessor (up to
5 Central Processor Units, CPUs) utilizing virtual
memory (16 mega 16 bits words) and demand paging. Messages
are transmitted from one PU to the memory of another
via the Supra Net. As all data transfers via the Supra
Net are approved by both PU's Memory Map, full hardware
protection against unintended interference between
PU's is ensured.
The PU is highly flexible because the selectance of
contained modules can be changed. The modules are interfaced
via a dual bus structure for reduction of bus contention
as shown in FIG. 3.2.2.1-3.
FIG. 3.2.2.1-3
3.2.2.1.2 T̲h̲e̲ ̲C̲h̲a̲n̲n̲e̲l̲ ̲U̲n̲i̲t̲s̲ ̲(̲C̲U̲)̲
The Channel Units contain the CR80 I/O controller modules
for interfacing towards peripheral equipment, communication
lines etc. The CU has an internal dual transfer bus
structure to ensure that no single failure can stop
operation of more than one I/O controller as shown
in figure, 3.2.2.1-4.
FIG. 3.2.2.1-4
The transfer buses, data bus A and data bus B, are
connected to two different PU's to ensure continuous
access to the controller modules (CTRL, LTU). The characteristics
of data bus A and data bus B correspond to the internal
buses of the PU.
The CIA-modules constitute the interface between the
word oriented internal transfer buses and the byte
oriented data channels.
The I/O controller modules are all based on the same
principle for interfacing to the channel unit bus structure
and for the external interfaces as illustrated in FIG.
3.2.2.1-5 .
FIG. 3.2.2.1-5
The interface to the CR80 system employs a multiported
RAM memory through which the data is exchanged. The
program for the controller module CPU is either resident
in PROM chips or is down loaded from the CR80. The
DISK CTRL, TAPE CTRL and PRINTER CTRL modules employ
PROM's while the Line Termination Modules (LTU) used
for interfacing communication lines, terminals etc.,
are loaded with programs from the CR80 meaning that
different protocols can be supported without hardware
changes.
The physical interface to the peripherals, communication
lines etc., is an adapter module located at the rear
of the CU Crate. For interfacing to communication
line, a special adapter module (LIA-S) is available.
This module is able to select a spare LTU module to
be used instead of a failing module. The spare LTU
can be back up for a number of active LTU's (n out
of n+1 redundancy). As the internal bus structure
is dualized, the power input is taken from two separate
sources to ensure that a failure in one power source
cannot stop the CU Operation.
3.2.2.1.3 B̲u̲s̲ ̲S̲t̲r̲u̲c̲t̲u̲r̲e̲
A CR80 computing system is organized around several
buses, which are described in this section.
A schematic overview showing the interconnection of
the different buses and units are given in FIG. 3.2.2.1-6.
FIG. 3.2.2.1-6
CR80 BUS STRUCTURE…86…1 …02… …02… …02… …02…
Internal in a Processing Unit two buses are available
for data transfer. Electrically and functionally they
are identical, the only differences are releted to
the type of module which are connected to them.
To the Processor Bus, the CPU's and Memory are connected,
and to the Channel Bus, DMA modules and memory are
connected.
A more detailed description of the Processing Units
and the modules used in it are given in the datasheet
package (see Technical litterature list, Part II A
of this proposal).
The two buses are located on each motherboard, mounted
in the back of the PU-Crate.
Internal in a Channel Unit two buses are used for data
transfer, Data Bus A and Data Bus B. The buses are
identically, and further use the same signals as the
Processor and Channel Buses. These two buses are located
on each motherboard, mounted in the back of the CU-crates.
The Data Channel is a flat cable bus connecting one
Processing Bus and one Channel Bus (located in the
same PU) with one or more Data Buses (located in one
or more CU's).
This is done by means of the Data Channel interface
modules (MAP-MIA), CIA-A & CIA-B; for detailed information
ref. datasheet packages for PU- and CU-modules (see
technical litterature list, Part II A of this proposal).
The SUPRA-bus is used to high speed data transfer between
processing units. The bus itself is a screened pair
of twisted wires.
The Configuration Control Bus is used in the Watchdog
Subsystem. The traffic on the configuration control
bus are directives from the Watchdog about switching
of LTU's and information to the Watchdog about the
Crate Power Supply Voltage Levels.
3.2.2.1.4 W̲a̲t̲c̲h̲d̲o̲g̲ ̲S̲y̲s̲t̲e̲m̲
The Watchdog (WD) consists of four parts:
o A Normal LTU
o A Watchdog Controller Adapter (WCA)
o A Configuration Control Bus Adaptor (CCA)
o Colsole Terminals
The interconnection is shown below:
FIG. 3.2.2.1-7
The Watchdog is used only for local supervision and
control, within the PU.
3.2.2.2. A̲c̲c̲e̲s̲s̲ ̲P̲r̲o̲c̲e̲s̲s̲o̲r̲ ̲a̲n̲d̲ ̲C̲h̲a̲n̲n̲e̲l̲ ̲U̲n̲i̲t̲s̲
In section 3.1.1 was the processor structure explained
and shown in fig. 3.1-1.
In this section is shown the exact configuration of
each PU and CU within the 3 PE's.
Fig. 3.2.2.2-1 shows the configuration of a PU in the
Front-end Processors. The 4 PU's are equipped identically.
The figures 3.2.2.2-2, -3, -4 and -5 show how the 4
CU's of the Front-End-Processors are equipped. It can
be seen, how the peripherals and terminals in the main
computer room are connected distributed on the 4 CU's.
Fig. 3.2.2.2-6 shows the configuration of the two identically
equipped Back-End-PU's.
Fig. 3.2.2.2-7 shows the configuration of the Back-End
CU.
The specifications for all the modules shown on the
figures can be found in the PU and CU datasheet packages
separately delivered with this proposal.
