At time of bidding ILS has a Norwegian subcontractor
to undertake site dsign and preparation on a NATO
program comprising 16 mainsites and 22 remote locations
throughout Europe.
The Maintenance and Technical Support section describes
the Maintenance Planning taking place at Christian
Rovsing. An overview of the mainenance documentation
is presented and CNCP's maintenance activities at the
three sites described.
The Training Section explains how Christian Rovsing
will train CNCP's computer technicians as well as Air
Canadas personnel. A matrix is presented providing
an overview of personnl category vs required courses.
Finally, the 5 proposed courses are described by stating
the objectives of the course and the prerequisites
of the participants.
The installation section describes the activities of
Christian Rovsing and CNCP relaing to installation.
CNCP will receive initial training at Christian Rovsing
and perform the installation at the three sites. Prior
to that, CNCP and Christian Rovsing will perform site
surveys and submit to Air Canada the Civil Works Requirement(CWR)
documentation. The CWR will specify how Air Canada
must prepare the site (equipment room) before installation
of equipment.
The documentation section presents how Christian Rovsing
proposes to develop the documentation for ACDN. The

9.2.2 M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲ ̲P̲l̲a̲n̲n̲i̲n̲g̲
The purpose of the Maintenance Planning Phase is to
establish a complete maintenance program which will
fulfil the contractual requirements for maintenace
and insure system reliability and availability to Air
Canada. Simultaneously it shall provide a solid base
for the development of the detailed maintenance documentation.
During the planning phase Christian Rovsing will be
working closely withtheir maintenance sub-contractor
to insure:
a) continuous resident support at the Network Control
Centre
b) adequate training programs for support staff
c) availability of maintenance specialist for emergency
situations
d) a multi-layered leve of support during and after
installation of the equipment.
e) availability of Recommended Spare Parts
f) availability of Tools and Test Equipment
g) the development of a comprehensive maintenance
plan.
Fig. III 9.2.2-1 illustrates the contens of the documentation
available at the close of the planning phase.
9.2.2.1 M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲ ̲P̲l̲a̲n̲
a) I̲n̲t̲r̲o̲d̲u̲c̲t̲i̲o̲n̲
The basic philosophy used in the configuration
of the system for Air Canada is to enable maintenance,
both preventive and emergency to be performed with
a minimum of system downtime thereby meeting the
availability requirements. This is achieved through
the use of redundant hardware modules and by extensive
use of the board swap principle once the sophisticated
fault detectio software has isolated a faulty assembly.
b) M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲ ̲E̲n̲g̲i̲n̲e̲e̲r̲i̲n̲g̲
Maintenance engineering describes the effort in
the area of maintenance and support necessary prior
to the installation of the equipment.…86…1
…02… …02… …02…
Fig. III 9.2.2-1
Maintenance Planning Activitie…86…1 …02… …02… …02…
The general approach to preventive maintenance
is that the applicable procedures are referenced
via an overall system maintenance sheet incorporated
in the various technical manuas. The special tools
and test equipment which will be used for maintenance
are listed and their applications shown through
scenarios displaying the structure of the hardware
with breakpoints.
A failure reporting system will be generated and
maitained throughout the warranty period. Incorporated
in this system are
- failure reports which will be filled in at
the installations and used in the screening
of systematic errors and used to modify the
spare parts stock
- a log book whichwill be located at each installation
- Field Change Notices used as applicable for
updating of the systems.
c) O̲n̲-̲S̲i̲t̲e̲ ̲M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲
On-site maintenance will be provided by Christian
Rovsing's sub-contractor, CNCP Telecommunications.
The tecnicians selected to perform these tasks
each have several years experience in supporting
similar systems. The technicians will, through
formal training courses, be capable of carrying
out preventive maintenance both on the CR80 equipment
and the cnnected peripherals. The preventive maintenance
required on the CR80 equipment is restricted to
simple tasks such as cleaning of dust filters,
inspection of LED's etc. Emergency maintenance
will typically be carried out on a module exchange
basis The trouble shooting techniques developed
for the system configuration will enable the maintenance
personnel to isolate and replace modules in the
CR80 equipment within one hour. Also the technicians
will perform modifications according to FieldChange
Notices.
d) M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲ ̲M̲a̲n̲a̲g̲e̲m̲e̲n̲t̲
The service technicians at the nodes will be trained
to carry out 1st level maintenance consisting of
preventive and emergency maintenance as previously
described. In most cases logic boards with know
faults will be returned to Christian Rovsing for
repair and then…86…1 …02… …02… …02…
returned to the spare parts complement of the node.
In some instances faulty modules, i.e. power supply,
fan assembly, will be repaired on-site. Christian
Rovsing will provide 2d and 3rd level maintenance
through field service engineers, inhouse repair
facilities, and software maintenance support.
9.2.2.2 M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲ ̲D̲o̲c̲u̲m̲e̲n̲t̲a̲t̲i̲o̲n̲
The maintenance documentation developed for this program
is shown in fig. III 9.2.2.2-1.
9.2.2.3 R̲e̲c̲o̲m̲m̲e̲n̲d̲e̲d̲ ̲S̲p̲a̲r̲e̲ ̲P̲a̲r̲t̲s̲ ̲L̲i̲s̲t̲ ̲(̲R̲S̲P̲L̲)̲
During the maintenance planning phase the RSPL will
be prepared based on an analysis of the H/W. At the
end of the planning phase the RSPL will be submitted
to Air Canada for approval. Hereafter it ill be referred
to as the Approved Spare Parts List (ASPL). Delivery
of the spares will take place simultaneously with the
installation of the equipment at each location. It
will be based on our current predictions of the failure
rate of the CR80 modules and their MTBF values supplemented
by our experience from similar projects. In its final
form the RSPL will be composed of
- CR80D modules
- Special OEM equipment
- Standard OEM equipment
The recommendation of the spares complement or the
CR80D modules is based on wellknown calculation formulas
for probabilities.
The recommendation of spares for the special OEM equipment
is based on the manufacturer's RSPL.
The recommendation of spares for the standard OEM equipment
is baed on our experience from similar projects. The
price will typically amount to 10% of the equipment
price.
9.2.2.4 T̲o̲o̲l̲s̲ ̲a̲n̲d̲ ̲T̲e̲s̲t̲ ̲E̲q̲u̲i̲p̲m̲e̲n̲t̲ ̲L̲i̲s̲t̲
During the maintenance planning phase a list of special
tools and test equipment (TE) will be prepred based
on an analysis of the H/W breakdown of the system.
The list will be incorporated as an appendix to the
maintenance plan and submitted to Air…86…1 …02…
…02… …02…
Fig. III 9.2.2.2-1…01…Maintenance Documentatio…86…1 …02… …02… …02…
Canada at the end of the planning phase. The special
tools and TE will be available at the sites during
the installation phase of the equipment.
The special tools and TE employe during maintenance
of the ACDN will be rather few due to the proposed
maintenance philosophy. Please refer to section 9.2.3.2,
Emergency Maintenance. Consequently, the only test
equipment necessary will be bus analysers. The following
analysersare proposed.
- V24 Communication Tester (RS 232-C)
- Signature Analyser
No special tools and TE are contemplated for the emergency
maintenance of the peripherals, however, some special
tools may be necessary for preventive maintenance.
9.2.3 M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲ ̲A̲c̲t̲i̲v̲i̲t̲i̲e̲s̲
9.2.3.1 P̲r̲e̲v̲e̲n̲t̲i̲v̲e̲ ̲M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲
Preventative maintenance will be carried out by Christian
Rovsing's sub-contractor, CNCP Telecommunications,
in accordnce with the procedures established in the
maintenance manual. The preventive maintenance required
on the CR80 equipment is restricted to cleaning of
dust filters, inspection of LED's etc. and the implementation
of modifications according to fieldchange notices.
The overall design of the system utilizing redundant
hardware will insure that preventive maintenance will
have a minimal effect on the performance of the system.
9.2.3.2 E̲m̲e̲r̲g̲e̲n̲c̲y̲ ̲M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲
Emergency maintenance, i.e. fault dentification and
module replacement will be carried out by the trained
technicians of Christian Rovsing's sub-contractor,
CNCP Telecommunications. Repair of defective subassemblies
will be undertaken by Christian Rovsing at no cost
to Air Canada uring the warranty period, and thereafter
any charges will be regulated by the terms and conditions
stated in the maintenance contract.
Implementation of field changes will be done by CNCP
technicians after instructions from Christian Rovsing.
solation of faulty subassemblies is accomplished by
the use of both on-line and off-line diagnostic software
programs. As stated elsewhere in this proposal, on-line
error detection programs will detect hardware faults
when they occur. This is accmplished both by background
checks and error detection during data transfer from
one subsystem to another. Depending on the type of
fault the "Watchdog" subsystem will reconfigure the
system designating the standby processor as active.
The defecive subsystem is now off-line where further
fault diagnosis can take place in the event the on-line
diagnostic program did not give specific error identifications
pinpointing a specific module. The off-line diagnostic
program provides for a much mre thorough check of the
various elements of a subsystem. In addition, this
program will be used to verify repaired modules.
9.2.3.3 M̲a̲i̲n̲t̲e̲n̲a̲n̲c̲e̲ ̲E̲f̲f̲o̲r̲t̲
The estimated maintenance effort at the Toronto site
will be 240 hours per month. Full-time on site coverage,
as specified in the RFP, will be provided rom the pool
of colocated CNCP computer technicians.
It is estimated that the total preventive and corrective
maintenance effort at the Montreal and Winnipeg sites
will be 60 and 55 hours per month, respectively.
The total maintenance requiremets could subsequently
be marginally adjusted upward or downward, depending
on the actual experience recorded by the sub-contractor,
CNCP.
9.2.3.4 P̲e̲r̲s̲o̲n̲n̲e̲l̲ ̲Q̲u̲a̲l̲i̲f̲i̲c̲a̲t̲i̲o̲n̲s̲
In case Air Canada elects to undertake all maintenance,
the following peronnel qualifications are applicable:
- Computer technician with a minumum of 5 years experience
in similar positions.
- participation in all training courses applicable
for the system.
9.2.4 T̲e̲c̲h̲n̲i̲c̲a̲l̲ ̲S̲u̲p̲p̲o̲r̲t̲
This section describes the Chritian Rovsing support
which will complement the maintenance program through
the warranty period and on.
9.2.4.1 H̲a̲r̲d̲w̲a̲r̲e̲ ̲S̲u̲p̲p̲o̲r̲t̲

After the project definition phase, during which the
Integrated Training Plan is written, the following
documentation is developed:
a) T̲r̲a̲i̲n̲i̲n̲g̲ ̲P̲l̲n̲
Each course is described in detail in a Training
Plan, which includes subsets of the course material.
b) C̲o̲u̲r̲s̲e̲ ̲O̲b̲j̲e̲c̲t̲i̲v̲e̲s̲
To define what the student must learn during the
course, the following is required:
1) The Skills and Knowledge pecification, defining
the outcome of the course.
2) Entry Standard, defining what the student is
able to do, and his knowledge before the course
start.
3) The Training and Enabling Objectives, which
define the gap between 1) and 2) above andthe
targets of the training.
c) I̲n̲s̲t̲r̲u̲c̲t̲o̲r̲'̲s̲ ̲M̲a̲n̲u̲a̲l̲
This manual consists of two volumes for each course.
Volume 1 contains:
a) The Training Plan outlining the course, which
is the instrument for development of the Instructor's
Guide Sheets
b) The Instructor's Guide Sheets and the Lesson
Plans.
Volume 2 contains all the reference material (apart
from selfcontained manuals, guides, etc.), i.e.
visual aids, questionaires, test items, and other
hand-outs. All this material will b referenced
by the Lesson Plans.
d) I̲n̲s̲t̲r̲u̲c̲t̲o̲r̲'̲s̲ ̲G̲u̲i̲d̲e̲ ̲S̲h̲e̲e̲t̲
To establish the outcome of a lesson (or possibly
a set of lessons), the Instructor's Guide Sheet
specifies the planned outcome of the lesson(s),
the training method which could be ued, aids and
references, enabling collection of necessary items
before the lesson is held. This sheet is the baseline
of the Lesson Plan(s).…86…1 …02… …02… …02…
…02… …02…
e) T̲h̲e̲ ̲L̲e̲s̲s̲o̲n̲ ̲P̲l̲a̲n̲
All the Lesson Plans of a course, together with
the Instructor's Guide Sheet, form the detailed
guide for the instruction of the class, and together
they makeup the entire course.
The Lesson Plan defines the main points of the
instruction listed by key points (key words).
The duration of each main point is indicated, the
method of instruction is marked, and the appropriate
references to manuals, aid, tests, slides, etc.
are noted.
The lesson plan, therefore, maps all planned events
during the lesson.
9.3.3 T̲r̲a̲i̲n̲i̲n̲g̲ ̲A̲c̲t̲i̲v̲i̲t̲i̲e̲s̲
Training of the different personnel categories will
be planned, so the training is concluded in advance
of the nstallation of the network in question.
The maintenance training is concluded in advance of
CNCP's upstart of training in Canada.
The courses are conducted at Christian Rovsing's facilities
on equipment, which is later installed in Air Canada'snetwork.
Optionally, courses can be conducted at the network
installations after site acceptance test.
The number of students per class will be limited to
10, unless other agreements are made. It is Christian
Rovsing's experience that 5 teams o each 2 students
is optimum, considering availability of training equipment.
9.3.3.1 T̲r̲a̲i̲n̲i̲n̲g̲ ̲T̲e̲c̲h̲n̲i̲q̲u̲e̲s̲
The main principle of Christian Rovsing's courses is
that student centered training methods are used wherever
possible.
To evaluate the outcome of th courses, oral questions,
quizzes and tests are used during the courses, and
a final practical and theoretical test is performed
by the participants.
The following training methods are used during the
courses:
a) Group-work: Specific tasks are istributed in
writing to the groups to work on.
The tasks may be theoretical or
practical examinations of the various
topics.
b) Reports: The groups report the results of
their tasks in a group session.
c) Discussion: The results of the groupsare discussed
by the class under guidance of the
instructor.
d) Lecture: Lectures are used (limited) for outlining
the basic rules for a given topic.
e) Informal
talk: Informal talk is invoked to obtain
feed-back to the instructor on the
outcme of the instruction.
f) Hands-on: Practical work is used extensively,
as this is the best way to implement
the use of theoretical knowledge
on the various topics covered by
other training methods. In the same
way, the instructor gets feed-backon
the student's understanding of the
topics covered in the instruction.
g) Tests: Tests and questionnaires are used
frequently, as these are highly motivating
and underline important points of
the instruction.
9.3.3.2 T̲r̲a̲i̲n̲i̲n̲g̲ ̲M̲a̲t̲e̲r̲i̲a̲l̲
Christian Rovsing offers to supply the following training

9.4.3.3 T̲y̲p̲i̲c̲a̲l̲ ̲L̲a̲y̲o̲u̲t̲
A typical equipment room layout of the Toronto installation
is shown in figure III 9.4.3.3-1. Room layout of the
Montreal and Winnipeg installations are shon on the
following figures III 9.4.3.3-2 and -3.
The equipment shown in the Toronto layout comprises:
- 2 Nodal Control Processor (NCP) Racks
- 5 Nodal Switch Processor (NSP) Racks
- 4 Electronic Mail Host (EMH)
Computer Racks
- 1 EMH Dic Cabinet
- 3 Network Management Host (NMH)
- Computer Racks
- 1 NMH Disc Cabinet
- 4 Color Displays
- 9 Visual Display Units (VDU)
- 4 Medium Speed Printers (MSP)
- 1 Line Printer (LP)
The tables and chairs shown on the layout have notbeen
quoted.
The layout presented in figure III 9.4.3.3-1 shows
two equipment rooms separated by a glass wall or a
wall with windows. The idea is to keep the noise level
low in the operator area by installing the computer
equipment separated fromthe control centre. A double
door combines the two areas. The tape decks and disk
drives, which have most often to be serviced, are installed
close to the door. The development and test area can
easily be separated from the network control centre
b a new wall. The computer equipment and control centre
equipment have been placed in functional groups and
as can be seen there is provided room for growth within
each group. The projected growth has been dotted on
the layout.
The racks are posit
