3.1 G̲E̲N̲E̲R̲A̲L̲ ̲S̲Y̲S̲T̲E̲M̲ ̲D̲E̲S̲C̲R̲I̲P̲T̲I̲O̲N̲
Christian Rovsing A/S 's proposal for the system architecture
of the ACCESS System is based on our extensive experience
of designing highly reliable and secure systems to
military users and civilian users with unique requirements
e.g. airline companies using our flexible CR80 computer
system. The CR80's is characterized by its reliability,
security and flexibility.
R̲e̲l̲i̲a̲b̲i̲l̲i̲t̲y̲
Our computer, the CR80 has been used to implement extremely
high reliable communication front ends, by using the
hot stand by concept in two systems working in parallel.
The same computer system is used in large cost effective
communication systems, where one computer is used as
a back up for several active computers.
S̲e̲c̲u̲r̲i̲t̲y̲
Many unique features of the CR80 allows the construction
of highly secure systems. The hardware of the CR80
provides total segregation of all application program
under control of a memory mapping hardware module.
The operating system software of CR80 called DAMOS,
Distributed Advanced Multiprocessing Operating System,
is built around a small highly secure kernel and a
number of operating system processes, each with its
own security profile.
Christian Rovsing A/S 's concept for implementing secure
systems entails a system architecture which differs
from the old fashion large mainframe systems, where
the software system, including both system software
and appliction software, is one large addressing room
with no or only minor segregateion of the various parts.
Christian Rovsing A/S has been following the US DOD
work on the definition of multilevel secure systems,
and we have presented our concept to DOD with great
success. Christian Rovsing A/S is presently in the
coding and integration phase of a large Computer Aided
Message Processing System, CAMPS to NATO which is being
evaluated by TRW from a security point of view before
deployment. The preliminary result of this evaluation
concludes that the CR80 equipped with the DAMOS operating
system is well suited for implementing a secure system
in accordance with military requirements.…86…1

F̲l̲e̲x̲i̲b̲i̲l̲i̲t̲y̲
The CR80 is a very flexible computer system, it allows
implementation of many functionally different systems
from very small systems (0.6 MIPS), e.g. protocol converters
to huge integrated systems (more than 30 MIPS), e.g.
Network Communication Systems.
The flexibility of the CR80 has been used by Christian
Rovsing A/S to implement a variety of different systems.
Similarly our customers have benefited from the flexibility
of the CR80 by getting expandable and field upgradable
systems with a large growth potential. The same hardware
modules are used to build both small and large systems,
allowing the sharing of spare parts for many different
systems.
3.1.1. A̲C̲C̲E̲S̲S̲ ̲S̲Y̲S̲T̲E̲M̲ ̲D̲E̲S̲C̲R̲I̲P̲T̲I̲O̲N̲
The proposed Access System will be described from three
different points of view,. i.e. the Hardware, Software
and the Communication Subsystem
3.1.1.1 A̲C̲C̲E̲S̲S̲ ̲C̲O̲M̲P̲U̲T̲E̲R̲ ̲H̲A̲R̲D̲W̲A̲R̲E̲
Christian Rovsing A/S propose to divide the computing
system in a front end and back end system. The front
end system will perform all the application processing
initiated by the terminal users, while the back end
subsystem will perform and coordinate all tasks related
to Data Base Management. By doing this it will also
offload the front end subsystem (Ref. FIG. 3.1.1.-1)
F̲r̲o̲n̲t̲ ̲E̲n̲d̲ ̲S̲u̲b̲s̲y̲s̲t̲e̲m̲
The Access Front End System consists of two sets of
fully dualized CR80 Systems. Each dualized system
comprises of two interconnected CR80. Each dualized
system is interconnected within itself to allow total
load sharing, when both CR80 computers are active and
all hardware modules are operational.
The fault tolerant front end system will continue to
work after the occurrence of a single point failure
because all system parts has been dualized. However,
as a consequence of the load sharing concept, where
no system part is kept as spare, a single point failure
will cause a lower performance. Because no system portion
is kept as spare, a single point failure might cause
a lower performance. Christian Rovsing A/S can configure
the front system in accordance with a graceful degradation
principle which maps the Access requirements for different
application classes:
1) No erroneous hardware modules will permit the processing
of all applications without limitations during
peak hour load.
2) A single error in a CPU Board (each CR80 computer
is configured with 2 CPU's) or a mirrored disc
controller will cause the removal of low priority
applications for the user group served by the CR80
in question during busy hour traffic.
3) One or more failures in one of two interconnected
CR80 Systems will cause the removal of low and
medium priority applications during busy hour traffic.
4) Double errors, which cause one system to fail completely
while the second system is running in degraded
mode will entail the removal of low, medium and
high priority applications if the system load is
substantial.
On top of these failures, which can be controlled automatically,
the flexibility and modularity of the CR80 Computer
System allows manual hardware module swopping. This
provides the system survivability in extreme failure
situations.
B̲a̲c̲k̲ ̲E̲n̲d̲ ̲S̲u̲b̲s̲y̲s̲t̲e̲m̲
The Back End System consists of a dualized CR80 System
and a mirrored set of dedicated Intelligent Database
Machine, IDM. The dualized CR80 monitors and coordinates
all tasks to be performed on the IDM. The dualization
used on the CR80 Back End System is the n + 1 concept
in its initial version (due to small workload), where
one Processor Unit, PU is stand by for one active PU,
while the associated Channel Unit, CU is dualized within
itself by having its two buses connected to the active
and the stand by PU respectively and by having a mirrored
set of all hardware modules.
The dedicated mirrored IDM's maintain two identical
versions of the data base. The IDM allows implementation
of many DMBS features in hardware and firmware resulting
in a much more cost effective and efficient DBMS implementation
than the old fashion host embedded DBMS Implementation.
The IDM ensures complete data base integrety independent
of terminal and other peripheral events, because of
the strict and well defined interface between the IDM
and the rest of the system.
The mirrored IDM concept serves several objectives:
- ensures fast and easy back up in case of disc failures,
because the system can continue operations with
only one operative IDM.
- load sharing between the two IDM is obtained by
a very high degree, because approximately 80% of
all data base transactions are 'read only' which
can be performed on each IDM in an alternating
scheme, while only 20% of the transactions are
'creates' or 'updates' requiring amendments to
both IDM's.
- avoidance of frequent periodic back up copying
and transaction filing, which entails long off
duty hour manning of the system.
The success of the CR80 is closely related to the three
main features mentioned earlier, reliability, security
and flexibility. These three characteristics are synonymous
with the three requirement set up by US Air Force,
i.e. ease of use, growth potential and operation and
maintenance.…86…1 …02… …02… …02… …02…
E̲a̲s̲e̲ ̲o̲f̲ ̲U̲s̲e̲ is imperative in a system with extreme
high reliability features, hence Christian Rovsing
A/S has dedicated many resources to build a computer
system with a logical architecture with modular building
blocks. In order to reach a high availability Christian
Rovsing A/S is using only first class quality, military
approved components with long time between failures.
On the other side, we are keeping time to repair as
low as possible by using extensive diagnostic software,
which locates failures to a single board and then we
provide board, swopping, i.e. replacement of a failed
module with error free modules without removing power
from the system.
G̲r̲o̲w̲t̲h̲ ̲P̲o̲t̲e̲n̲t̲i̲a̲l̲ on the proposed ACCESS is very large.
The initial ACCESS configuraton consists of 6 Processor
Units, i.e. 4 front ends and 2 back ends, while standard
CR80 configuration can have up to 16 PU's controlled
by the operating system software DAMOS. Further expansion
can be achieved by segregating the front ends and the
back ends under two DAMOS carnations.
The initial processing power within each PU is achieved
by two CPU boards, while DAMOS in its standard version
supports up to five CPU's per PU.
A rough estimate of the growth potential in processing
power under DAMOS standard is that while initial processing
is covered by 12 CPU's in 6 PU's the maximum standard
processing power is 80 CPU's in 16PU's. This is more
than 500% expansion capability.
The number of pheripherals in a CR80 Configuration
is practically unlimited and all types of peripherals
can be attached because the individual peripheral processors
are implemented on various boards, e.g. disc controller,
tape controller, line termination units.
The amount of memory that can be attached to each PU
is 1 Megaword and 15 Megaword in associated CU's.
Disc and tape storage can be attached to the extent
requested
O̲p̲e̲r̲a̲t̲i̲o̲n̲ ̲a̲n̲d̲ ̲M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲ features have been automated
to a large extent. A watchdog microcomputer monitors
and controls each fault tolerant system, i.e. one back
end and 2 front end systems. The purpose of a watchdog
is to receive 'keep alive' signals from all modules
in a system and to initiate reconfiguration in case
of module fall-outs.
The page is intentionally left blank.
The mirrored disc and data base concept also provides
easy and safe operation in a very cost-effective fashion
because of load sharing for all read requests (app.
80% of load).
Special maintenance and diagnostic software will provide
easy error location and repair when errors do occur.
3.1.1.2 A̲C̲C̲E̲S̲S̲ ̲C̲O̲M̲P̲U̲T̲E̲R̲ ̲S̲O̲F̲T̲W̲A̲R̲E̲
The proposed ACCESS System will run under control of
the CR80 operating system DAMOS, Distributed Advanced
Multiprocessing Operating System, which resides in
the CR80's of both front end and back ends. The two
mirrored IDM's, Intelligent Database Machines are equipped
with software/firmware to implement a relational database.
D̲A̲M̲O̲S̲
This is Christian Rovsing A/S's standard operating
system used to control all different types of CR80
configuration in a highly secure manner, well suited
for implementation of systems in military environments.
DAMOS can support from 1 to 5 CPU's in each processor
Unit, PU's and it allows 16 PU's to be run as one integrated
system. DAMOS can utilize 16 Megawords per PU, 1
Megaword in the PU itself and 15 Megawords in attached
Channel Units. Each execution of a program is called
a Process and each process can address 64 kiloword
of instructions and 64 kilowords of data. Each process
is totally segregated from other processes by a hardware
mapping modules, which ensures a highly secure system
. Instruction areas can not be modified. Similarly
the DAMOS itself is controlled by a small kernel which
monitors the processing of all other processes and
hence performs security checks on executing software.
R̲e̲l̲a̲t̲i̲o̲n̲a̲l̲ ̲D̲a̲t̲a̲ ̲B̲a̲s̲e̲ ̲M̲a̲n̲a̲g̲e̲m̲e̲n̲t̲ ̲S̲y̲s̲t̲e̲m̲
The DBMS is implemented on two dedicated machines to
provide the most cost-effective and efficient system.
Similarly the relational concept is much more user
friendly than earlier concepts like structural and
network organization.
A simple comparison of the three data base models,
relational, hierarchial and network provides the following
results:
- the language features required to declare a relational
data base are a subset of those required to declare
a hierarchial data base, and these in turn are
a subset of those required to declare a network
database;
- the language operators required to manipulate a
relational database are a subset of those required
to manipulate a hierarchial database, and these
in turn are a subset of those required to manipulate
a network database;
- (For a given operator, as applicable) the language
operators required for a relational database are
a subset of those required for a hierarchial database,
and these in turn are a subset of those required
for a network database.
However, one major draw back has prevented the relational
database from being used more widely than the other
two, and that was performance requirements. When implemented
on traditional host computer system, the relational
database concept could not be tuned to the extent of
the other two models.
Now, due to the three earlier simple characteristics
it has been feasible to implement many data base management
functions directly in hardware and firmware with the
result that all short-comings of the relational model
has been more than offset by using dedicated systems.
The IDM provides integrated data dictionary for all
database items, and the transaction management features
ensures a selfcontained integrated database after system
failures. The IDM controls multiple simultaneous users
and provides extensive access control to protect information
if the database. Audit logging of transactions are
provided. The IDM can also store user defined commands
to simplify and minimize execution time.
E̲a̲s̲e̲ ̲o̲f̲ ̲U̲s̲e̲ of ACCESS software will be provided by
Christian Rovsing A/S because our experience in implementation
of user friendly man-machine systems like CAMPS to
NATO will ensure that the US Airforce gets the best
System Menus and prompts are used throughout the system
and HELP functions are available to the inexperienced
user. Similarly the relational database concept is
more user friendly than previous concepts.
S̲e̲c̲u̲r̲i̲t̲y̲ features is one of the major characteristics
of the DAMOS operating system, and the positive response
Christian Rovsing A/S has got from NATO, TRW and DOD,
who have reacted to us will ensure the US Airforce
that security aspects are well covered in this proposal.
F̲l̲e̲x̲i̲b̲i̲l̲i̲t̲y̲ has always been a major objective to Christian
Rovsing A/S. We use the same operating system for all
types of systems and our customers are ensured growth
capabilities due to this concept.
O̲p̲e̲r̲a̲t̲i̲o̲n̲s̲ ̲a̲n̲d̲ ̲M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲ has been automated to the
extent possible by extensive use of maintenance and
diagnostic software.
I̲m̲p̲l̲e̲m̲e̲n̲t̲a̲t̲i̲o̲n̲ and especially field upgrades are easily
obtained because of the standard versions of DAMOS
is already prepared for all different possible configuration.
3.1.1.3 C̲O̲M̲M̲U̲N̲I̲C̲A̲T̲I̲O̲N̲S̲
The proposed ACCESS System will utilize the X-Net local
area network to interface all remote and local terminals,
i.e. VDU's CGDU, Video Copies and Letter Quality Printers.
The local area network of ACCESS is built of 8 dualized
X-Nets in order to provide the requested minimum delay
and the requested free terminal connect points. The
dualization concept ensures that a single point failure
in a net will not prevent any terminal from operative
usage.
G̲r̲o̲w̲t̲h̲ ̲P̲o̲t̲e̲n̲t̲i̲a̲l̲ is achieved in ACCESS's Configuration
because new X-Nets can be added to the front ends as
requested. Each X-net has a bit rate of 2 Megabits
giving a total bit rate of 16 megabits. The X-Net is
already in use as a virtual circuit switching system
with a uniform delay for data transfer in the Danish
Defence Integrated Communication System, FIKS. This
capability of mixing packet switching and line switching
is a prerequisite for a digitized voice communication.
The digitizing technic called Line Predictive Coding,
LPC can be used to transform the voice to 2400 bit/sec
data frames, which can be line switched on the X-Net.
Regarding video communication, then the X-Net utilizes
coaxables known from TV-antenna connections, but the
provided hardware modules and software used in the
X-Net must be replaced with more efficient equipment.
F̲l̲e̲x̲i̲b̲i̲l̲i̲t̲y̲ is provided in the ACCESS local area network
by the installation of 8 dualized X-Nets. Each X-Net
is only supporting approx. 50 terminals, while 250
can be served on each net, giving 200 spare terminal
positions for terminal mobility.
I̲m̲p̲l̲e̲m̲e̲n̲t̲a̲t̲i̲o̲n̲ of the local area network can be done
within the procedures allowed in the ACCESS RFP, i.e.
2 inch tubes. Connections to remote site using encrypted
lines can be established anywhere on an X-Net.

3.3.1 C̲e̲n̲t̲r̲a̲l̲ ̲C̲o̲m̲p̲u̲t̲e̲r̲ ̲E̲q̲u̲i̲p̲m̲e̲n̲t̲ ̲-̲ ̲R̲o̲o̲m̲ ̲-̲ ̲B̲B̲3̲0̲
A proposed equipment room layout of the ACCESS Computer
System installation is shown in FIG. I 3.3.1-1 and
2. FIG. I 3.3.1-1 shows the first increment installation
(C1) and FIG. I 3.3.1-2 shows a proposed expansion
of the installation in room BB30 with second increment
and augmentation equipment.
3.3.1.1 F̲i̲r̲s̲t̲ ̲I̲n̲c̲r̲e̲m̲e̲n̲t̲ ̲I̲n̲s̲t̲a̲l̲l̲a̲t̲i̲o̲n̲
a) the equipment shown in the first increment installation
(FIG. I 3.3.1-1) comprises:
Pos 1-8 two front end procesors FP1, FP2)
mounted in 2x4 standard 19" rack
Pos 9-11 one backend processor (BP)
mounted in 3 standard 19" racks
Pos 12-13 two Disc Drive interfaces, one cabinet
each.
Pos 14-29 2 x 8 data base disc drives in 16
cabinets.
Pos 30-31 one position (table) with two operator
consoles, one for each frontend processor.
Each console is a hardcopy printer
with keyboard.
Pos 32-33 one position (table) with one operator
console, for the backend processor.
The console consists of a visual display
unit and a hardcopy printer with keyboard.
Pos 34 one optical character reader, selfcontained
Pos 35 one color camera, selfcontained
Pos 36 one color graphic copier, selfcontained
Pos 37-38 one position (table) with graphic
digitizer equipment
Pos 39-40 two line printer, pedestal mounted
Pos 41 one high speed low impact printer,
pedestal mounted.
The tables and chairs shown have not been quoted.
a) The layouts reflect the floor space required by
cabinets and the operator positions. The access
dimensions on FIG. I 3.3.1-3 thru 4.
b) The layout shows room BB-30 divided into three
areas separated by two walls with windows. Only
two of the areas are to be used for the first increment
installation as indicated. The idea is to keep
the more noisy computer and data storage equipment
separated from the working positions. A double
door combines the two areas. Another double door
at the entrance to the working area is proposed.
The hallway at entrance to room BB-30 has been
maintained in the main passage way or walking area
through the two doors as can be seen from the drawing.
REV. 1 1983-03-18
c) The layouts reflect the floor space required by
cabinets and operator positions. The access dimensions
for racks and terminal equipment are shown on FIG.
I 3.3.1-3 thru 5.
The racks and disc cabinets are positioned such
that sufficient clearance is maintained for access
to the front and rear of the equipment. The disc
cabinets are on rolls and are pulled out in the
passageway for access to the rear of the cabinet.
Otherwise, only few constraints as to the placement
of the equipment exist. The final layouts will
take into account human factors, segregation of
functional activities, access for maintenance and
other considerations or preferences of the operating
personnel.
One of the tasks to be performed at the site survey,
as described in PART II, section 7.2.1, is to work
out the optimal layout in conjunction with AFCC.
d) The fact that room BB-30 is provided with a computer
floor has been utilized in the proposed layout.
The heaviest rack is well within the floor load
limit of 1200 Kp/m…0e…2…0f… (250 lbs/sq foot) for the raised
floor as can be seen from the following calculation:
Floor load of heaviest rack:
̲ ̲W̲e̲i̲g̲h̲t̲ ̲ ̲ ̲ = ̲ ̲ ̲3̲2̲5̲ ̲k̲g̲ ̲ ̲ ̲ = 516 kg/m…0e…2…0f… (106 lbs/sq
foot)
Floor space 0.6 x 1.05 m…0e…2…0f…
Since the rack is provided with access space at
front and rear, the distributed floor load is considerably
smaller. Equipment Weight and Dimensions are given
in table 3.3.1-1.
e) All equipment shown is air ventilated. The equipment
racks are cooled by fans with intake in the front
and exhaust at the top, as shown in FIG. I 3.3.1-6
thru 7. The disc drives are cooled by fan with
air intake at the bottom of the cabinets and exhaust
at the top, as shown in FIG. 3.3.1-8.
The raised floor is to be provided with grills
at each disc drive location and computer floor
ventilation is required.
f) Power to equipment is fed from individual fuse-protected
208 VAC or 120 VAC outlets. The required power
supply for equipment and equipment rooms are given
in table II 6.1-1. (The power supply characteristics
are given in Section 3.2 and Part II, Section 6.1,
where other environmental characteristics are also
listed.
g) It must be emphasized that AFCC is responsible
for the building reconstructions (i.e. walls, windows,
door, raised floors etc) to be made in BB-30 and
the installation of airconditioning and power.
It is also anticipated that AFCC will provide
and install signal cable ducts.
Contractor will specify his requirements to the
installations in the site preparation requirements
(SPR). Contractor will provide and install the
signal cables between his equipment in the AFCC
provided cable ducts below the raised floors.
Contractor will connect his equipment to the power
outlets provided by AFCC. The required location
and quantity of the power outlets will be specified
in the SPR.
3.3.1.2 E̲X̲P̲A̲N̲S̲I̲O̲N̲ ̲I̲N̲ ̲R̲O̲O̲M̲ ̲B̲B̲-̲3̲0̲
a) The proposed expansion of the first increment installation
is shown in FIG. I 3.3.1-2.
As can be seen from the figure there is available
space in Area A for installation of up to 17 additional
disc drives and 4 more backend processor racks.
It is anticipated that the two frontend processors
do not require additional rack space for the C2
and C3 expansion. Nevertheless, an extra rack
can be placed next to FP#1.
Up to 2 x 8 disc drives can be added to the first
increment installation in Area A without requiring
installation of extra backend processor racks.
If additional disc capacity is required two more
backend processor racks are to be installed.

3.3.2.1 N̲E̲T̲W̲O̲R̲K̲ ̲T̲O̲P̲O̲L̲O̲G̲Y̲ ̲A̲N̲D̲ ̲C̲O̲N̲D̲U̲I̲T̲/̲C̲A̲B̲L̲E̲
̲R̲U̲N̲S̲
a) Christian Rovsing proposes a local area network
for ACCESS consisting of eight dualized communication
nets called X-Nets (see part II, sections 1 and
2)
The network is prepared for support of up to 1968
terminal devices (8 X-net, each with 246 terminal
devices) without hardware modifications to the
network.
b) The Network Topology is shown in FIGURE 3.3.2-1
and 2.
The network controllers (XCT) and computer interface
(TIA) are located in room BB-30 of building 500
and the network cables are distributed from this
room to all designated areas within building 500,
50l, 40, 4l and 407. This means that only branching
units and amplifiers called XAB are to be installed
outside room BB-30, in building 500 and 501. It
is anticipated that the communication interfaces
(XCP), which interfaces to the crypto-
graphic units will be installed in the crypto-room
of building 50l. In the crypto-rooms of building
40, 4l, 407 is also installed an XCP, together
with an X-Net Controller (XCT) as shown.
c) Coaxialcable with an outer dia of 7mm is used for
the network. The Net is laid out so that every
room can be serviced. The distribution of terminals
on each branch of an X-Net is shown on the Topology
Drawing. The room number and the quantity of C1
and C2 terminals for each room is indicated and
the number of terminal outlets are summarized for
each branch. In order to show the expandability
and flexibility of the proposed net a number of
additional terminal device connections are evenly
distributed throughout building 500/501 and indicated
on the topology drawings next to the C1/C2 figure
as "EXT XWO". …86…1 …02… …02… …02… …02…
For each X-net branch is therefore shown:
- the quantity of C1/C2 terminals
and their distribution on allocated
rooms.
- the total EXT XWO number within
a branch evenly distributed on the
junction/pull boxes referred by
J-number.
This has been amplified in table I. 3.3.2-1.
The EXT XWO figure, therefore, specifies the number
of termination boxes (XTA/XWO), which can be installed
on each branch at terminal relocations, during
C3 expansion, or later expansions. The EXT/XWO
figure has been calculated considering a maximum
length of 800M per X-net branch, the requirement
for 1800 terminal device connections evenly distributed
throughout building 500/501, a maximum of 64 terminal
devices per branch and a maximum of 246 terminal
devices per X-net.
d) The proposed conduit/cable runs for all the designated
areas within buildings 500, 501, 40, 41 and 407
are shown in FIG. I 3.3.2-3 thru 12. The Steel
Electrical Metallic Tubing (EMT) Conduit is run
above the suspended ceiling in the hallways of
buildings 500, 40, 41 and 407. In Building 501
the EMT is run above the suspended ceiling within
the rooms.
The Conduit run has been drawn so that every room
in buildings 500/501 can be reached from a junction/pull
box. In buildings 407, 40 and 41 at least the indicated
rooms are serviced.
The location of junction/pull boxes and branching
units/amplifiers are shown on the drawings.
A total of 345 junction/pull boxes each of size
300h x 210w x 110d are evenly distributed throughout
the buildings.
Each junction/pull box is shown with "taps" which
specifies the following:
- terminal device connections (taps)
for C1/C2 terminals are indicated
with room number.
- additional terminal device connections (taps)
on each X-net are specified by a number of
possible connections per junction/pull box.
(The number is written within a circle attached
to each junction box on the conduit/cable plan
drawings).
- The sum of terminal device connections for
C1/C2 and encircled connections exceeds 1800.
e) It should be noted that the number of possible
connections (encircled number) to a junction/pull
box can be varied within a X-net branch i.e. the
number of connections to a junction/pull box can
be adjusted to the X-net within a certain area
of the building.
f) The branching units/amplifiers (XAB) are indicated
with a triangel symbol on the drawings and are
anticipated to be located above the ceiling near
the lift shafts in building 500/501. A total of
56 XAB Boxes each of size 300h x 210w x 110d are
proposed.
The termination boxes containing XTA/XWO for the
C1 and C2 configuration of terminals are only indicated
on the conduit/cable plans. A network detail with
a typical installation is shown on figure 3.3.2-13
and 14. It is anticipated that the XTA/XWO boxes
for the C1 terminals only are to be installed during
the first increment installation and only Termination
boxes containing XTA/XWO for C1 terminals have
therefore been proposed.
A total of 287 termination boxes for C1 terminals,
each of size 300mm(h) x 210mm (w) x 110mm(d) are
proposed. (One for each terminal device).
g) Figure I. 3.3.2-13, 14 show a typical distribution
to terminal devices from a junction box.
The figures show how a conduit/cable installation
can be performed in a local area. Note that connection
of additional terminals are made directly from
the first installed termination box.
The connection between the junction/pull box is
made with 1 1/4" EMT and so is the connection of
additional termination boxes.
The conduit between the junction/pull boxes are
2" EMT and a total length of 4000m has been estimated
from the drawings. The 1 1/4" EMT between junction/pull
boxes and termination boxes in the terminal rooms
have been estimated to 1800m for the C1 terminals.
Note that the 2" conduit length can be reduced
if the penetrations to different floors can be
made at convenient places. The conduit run between
floors has been made through the lift shafts in
this proposal. Suitable penetrations are to be
considered on a site survey.
