QUESTION NO 6
-------------
Section 1.4 will be amended with the following text
added as last part of section: "In the following, the
terms circuit and channel are of logical nature, whereas
line is the actual physical implementation of a channel.
A circuit may have one or more channels associated;
outgoing message traffic is always queued for a circuit
followed by transmission over a channel according to
a simple algoritme, e.g. first channel available in
a certain order."

refer section 2.3".
QUESTION NO 20
--------------
Section 4.2.4.1. will be amended to clarify the command
executian conditions: In section 4.2.4.1. pg. 166:
"Completion of command format followed by entry of
the confirmation code will cause the execution of the
command". In section 4.2.4.1 c): ".... entering the
mnemonic command. For certain commands as specified

QUESTION NO 23
--------------
Messages will be printed at the printer positions which
are available to the supervisor (refer section 4.3.5.2
and 4.3.5.3). The wording "Low speed" will be removed.
QUESTION NO 24
--------------
The incoming message reception and analysis is directed
towards parameter isolation and not fault finding except
when it concerns security parameters. This is illustrated
by the tables 4.2.1.2.1.-1, 4.2.1.2.2.-1 and 4.2.2.1.1.-1,
4.2.2.1.2.-1. Documents like Annex B have been worked
out and agreed upon with the CAMPS purchaser and presents
a set of rules for the CAMPS system. Likewize, we expect
to discuss with the CROSSFOX purchaser the importance
of the format line parameters in order to dertermine
which
1. have to be correct
2. may be corrected automatically by the MPF system
based on redundant information.
3. may be left incorrect in the message.
QUESTION NO 25
--------------
The following text will be amended to section 4.2.4.8.
as 3rd subpara: "Each report format will be subject
to agreement by purchaser during design", and the following
text will be added to section 4.2.4, 4th subpara: "A
precedence ranking of all transactions originated or
received at supervisory position will be proposed as
part af system design".
QUESTION NO 27
--------------
The answer to this question will additionally include
the answer to question 28. the contents of section
4.2.4.9(b) will be amended to clarify automatic/semiautomatic
diagnostics and maintenance programs. The complete
text of this section is replaced as follows: "The Processor
Units and the watch-dog assembly in coorporation will
facilitate the execution of on-line automatic selfdiagnosis
based on equipment monitoring and the analysis of software
completion codes. Special emphasis will be put an fault
isolation and performance degradation evaluation in
connection with periferal equipment. Consequent automatic/semiautomatic
reconfiguration actions are described in section 4.2.4.9.
c). Further to the selfdiagnosis (and possibly as a
result of a diagnostics report) the operator at the
engineering position may start the execution of automatic
on-line test programs which will not interrupt the
normal operation of the system. Same programs may be
run at the redundant PU (status changed from operational
to off-line or from stand-by to off-line) and will
include the execution of test of off-lined periferal
equipment".
The section 4.2.4.9.c. will be amended to clarify the
automatic/semiautomatic actions resulting from detections
of fault conditions. The existing text of this section
will be replaced by the following amendment, which
in turn will be followed by the answer to question
29 inserted as the last part of the section: "The detection
of a fault condition will result in the automatic withdrawal
of the faulty equipment from service and in many cases
switch over to redundant units. A report is always
issued at the printer of the engineering position with
details concerning the possible need for operator intervention.
QUESTION NO 28
--------------
Refer to answer for question 27.
QUESTION NO 29
--------------
Section 4.2.4.9(c) will be amended to further clarify
the reconfiguration actions executable from the engineering
position in case of failure and also for the case of
maintenance etc. The following text will be inserted
at the end of section 4.2.4.9(c)." "The operator at
the engineering position will have the facilities to
specify equipment switchover and and/or the withdrawal
in an orderly way of equipment from service as a result
of possible error/degradation indications, need for
maintenance, or other purposes. System monitoring will
be performed automatically to ensure the existence
of at least the minimum configuration for maintaining
proper service, such as the continuation of message
accountability. In case of violations a report will
be issued to the engineering position.
QUESTION NO 30
--------------
Section 4.2.6.3 will be amended as follows: "Storage
occupancy with respect to messages is defined as the
percentage of allocated message storage capability
which is occupied. It will be maintained .....".
QUESTION 31
-----------

by a received service message. The format of this message
shall for ACP 127 be of type abbreviated service message
(FL1, 2, 3, 4 and 5 only) with a suitable and easely
detectable text in format line 5. A similar format
is proposed for an ACP 126 service message. The final
layout is subject to agreement with purchaser.
QUESTION NO 33
--------------
Mounting of a volume means the physical process of
applying a new disk to the drive. According to IFB,
para 5.1.2.7.2(g) the "time" associated with retrieval
is from the issue of the retrieval request which we
interpret as the "suitable procedure" following the
loading mentioned in 5.1.2.7.2 . Consequently, section
4.2.7.2(d) may for clarification be amended: "10 minutes
from the time the volume is loaded and the issue of
a subssequent retrieval request".
QUESTION 34
-----------
Section 4.2.7.1 contains the requirements a) to c)
of para 5.1.2.7.4 of the IFB, when introducing the
following amendment concerning CTS and ATOMAL messages:

are kept".
Section 4.2.7.2 b) contains the requirement e) when
inserting the following clarification in the last sentence:
"Release DTG without zone suffix".
Section 4.2.7.2 b) will be amended to contain the requirement
d) as the last sentence: "Data messages are only retrievable
for retransmission and will not be displayed locally".
Section 4.2.1.3 will be amended to contain as the third
para: "Data messages are not subject to local delivery".
QUESTION NO 35
--------------
Section 4.2.8.4. will be amended with the following
addition: "The off-loading is a back-ground activity
(low priority process), which will not impact the concurrent
normal processing. The transfer is basically a transfer
from on-line to off-line storage media".
QUESTION NO 37
--------------
Section 4.2.9.5 will be amended with the following
text: "... resetting of the PU(S) and specification
of the restart category(the latter being a sigle command/from
the operators console). Further actions are automatics".
QUESTION NO 38
--------------
Section 4.2.9.6. will be amended to clarify the measures
taken to ensure message traffic continuity. The existing
test will be replaced as follows: "Message traffic
continuity after failure will be ensured in a manner
which depends on the failure category as follows:
a) A total system failure involves the loss of traffic
data base, partly or in full, up to the time of
failure. In this case a service message is sent
to the alternate MPF requesting the transfer of
its data base. System users will be informed of
the status concerning messages in preparation at
this MPF as soon as the data base has been established.
b) Other failures, where the historical database is
intact to the moment of failure, will result in
the following recovery actions:
- transmission of not fully transmitted outgoing
messages with new transmission sequence number.
- resumption of retransmission of not yet transmitted
relay traffic.
- retransmission of messages of the highest precedence
levels for which receipts are still pending (the
possible recovery of receipts as a result of
retransmission requests (refer below) will be
ignored and the duplicate nature of the message
will be indicated).
- the supervisor may inhibit the retransmission
of relay traffic received earlier than a specified
point in time. He may also prevent retransmission
on basis of addressee, routing or precedence.
Each message thus treated will result in a log
entry with suitable annotation.
- system users will be informed of the status of
messages in preparation at this MPF.
QUESTION NO 40
--------------
Section 4.2.9.9. will be amended to read: "System data
tables will be residing on dual disks which in connection
with frequent back-up of dynamic system data to the
same disks will provide the continuity in recovery
situations"
