Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

1. INTRODUCTION
A number of boards in the ISPBX system have DIL switches and/or straps, which have to be
set in the correct position during installation or replacement of the boards. This chapter
contains all the boards which do have those switches/straps. Also directions are given how to
set those switches/straps to suit a particular mode of application. In general the PCT boards
have more than one circuit mounted; so in that case the switches/straps have to be set for each
circuit individually.

An ALC-E provides the 2-wire line interface between an analogue extension and the ISPBX.
The ALC-E board has 16 of those interfaces (circuits).
It is possible to use only eight of the ALC-E circuits by means of strap X1-1. In this way an
ALC-E can also be used as an ALC-A.
The strap is drawn in position 101-102 for 16 ALC-E circuits: for 8 ALC circuits the strap must
be placed in position 102-103.

2.4. ALC-G
An ALC-G provides the 2-wire line interface between an analogue extension and the ISPBX.
The ALC-G replaces all versions of the ALC-E and ALC-F. It can not be used instead of the
ALC-A.
The ALC-G is a board with 16 interfaces (circuits). Connectors are fitted to the board for a
possible future extension board. The hardware is designed in such a way that the adjustment
range of the transmission characteristics matches with the currently known country
requirements. The maximum line current is 35 mA and reverse polarity is supported.
Note: The line polarity of the ALC-A and the ALC-E is the opposite of the line polarity of the ALC-F
and the ALC-G.
Two packages can exist on a card, an initial and a downloaded package. The initial package is
factory-installed and can only be modified in the factory.
PPU systems and systems of PMC release < or equal 405.08/505.08 only use an initial package
on the board, even if another package is downloaded. The transmission plan is set by means
of the DIL-switches.
As from SSW 805.28 and PMC packages 405.10/505.10,. the ALC-G uses only the
downloaded package. In this case the DIL-switches are not used for the transmission plan.
Without downloading, the card can be used on SSW 640/SSW2xx/SSW300/SSW7xx/SSW8xx
up to PMC 405.08/505.08 (and not with PMC 405.09/505.09).
• Transmission Plans
An ALC-G board can simultaneously contain two downloaded transmission plans, each
circuit can have either one of these transmission plans. The transmission plan is specified
with the bytes 13 and 14 of signalling group 32xx. When bytes 13 and 14 are 0 (default),
then the used transmission plan is specified with the bytes 33 and 34 of signalling group
9800. Bytes 33 and 34 are 1 by default.
A circuit can alternate between the two downloaded transmission plans.
Example:
Byte 13 of signalling group 3205 = 3 (English), transmission plan A.
Byte 14 of signalling group 3205 = 1 (International), transmission plan B.
Bit 4 of sigalling group 3205 = 0, so 3205 uses plan A
Bit 4 of signalling group 3204 = 1, so 3204 uses plan B
Bit 4 of signalling group 3210 = 0, so 3210 uses plan A.
ASBRDS:11,1,6,3205,35;all circuits have plan A.
CHPCTB:11,1,12,3204;only circuit 12 uses plan B.
15. 11
CHPCTB:11,1,15,3210;circuit 15 uses plan A.
• Signalling Parameters
Signalling parameters are downloaded for all circuits on an ALC-G board, two of these
signalling parameters are projectable for each individual circuit: on/off hook debouncing
and ground key debouncing time.

2.5. ALC-GP
The ALC-GP board (ALC-General Protected, 12NC: 9600 040 28000) has the same
functionality as the ALC-G except for a protection circuit per line to fulfil the requirements for
the Chinese market (YD/T 950-1998). These requirements include the ITU-T K.20:1996
recommendation.
2.6. ALC-G(R)
The ALC-G(R) is the redesigned version of the ALC-G and ALC-GP.
The ALC-G(R) has the same functionality as the ALC-GP : it provides the 2-wire line interface
between an analogue extension and the ISPBX.The board contains 16 interfaces (circuits). The
ALC-G(R) replaces all versions of the ALC-G and ALC-GP. It can not be used instead of the
ALC-A. See the description of the ALC-G for more details of the LEDs, connectors and DIP
Switch Settings.
19. 15
2.7. ALC-GM/GD
The ALC-GM/GD replaces all versions of the ALC-E, ALC-F and ALC-G/GP/G(R).
See the description of the ALC-G for more details of the LEDs, connectors and DIP Switch
Settings.
The ALC-GM/GD provides the 2-wire line interface between an analogue extension and the
ISPBX :
- the ALC-GM is a mother board with 16 interfaces (circuits).
- the ALC-GD is a daughter board with 16 interfaces (circuits).
When the daughter board (ALC-GD) is present on the mother board (ALC-GM), the
combination offers 32 interfaces in total.
The ALC-GM fits in a PM2500 shelf just like an ALC-E or ALC-F (all 16 circuits). However the
combination ALC-GM plus the daughter board ALC-GD is mechanically to wide to fit in a
PM2500 board position.
Note that the ALC-G/GP/G(R) can not be used as a motherboard to mount the ALC-GD
daughterboard !!!
Projecting aspects :
- the ALC-GM with the daughter board ALC-GD has to be projected as one ALC with 32
circuits, board type 59 and signaling group 321C.
- the ALC-GM without the daughter board ALC-GD has to be projected as one ALC with
16 circuits, board type 6 and signaling group 3205 or 3210.
- signalling group 321C is supported from PMC packages 405.10.01 en 505.10.01 and all
PMC-G 810 packages.Board type 59 is supported from SW805.28 onwards.

Figure 3-1 Layout Front Connector FBA & FBD
There are two types of KTLCs: the 8 circuits per board versions with a fixed transmission plan
and the 8 circuits per board version with a software selectable transmission plan.
The fixed transmission plan KTLCs are:
- KTLC01 :according to transmission plan 01 (e.g. required for the Netherlands);
- KTLC02 :according to transmission plan 02 (e.g. Germany);
- KTLC03 :according to transmission plan 03 (e.g. United Kingdom).
The software selectable transmission plan KTLC is KTLC-A: transmission plan set by the
signalling block. The transmission plans supported by the KTLCs can also be used in other
countries next to the ones listed above.
The KTLC to be used in a specific country depends on the local transmission plan. The
transmission levels of the various KTLC boards are selected by means of strap settings; see
figurefor the location of the straps.
23. 19
• Strap X1.1
The straps of X1.1 are used to set the mode of operation of the KTLC; see the table
below. For normal operation of the key telephones, all straps of X1.1 must be installed.

This strap is used to connect or disconnect the back-up battery of the memory circuits on
the KTLC board. With the battery connected these circuits retain user-defined data during
a system power failure. User defined data is also retained when the board is removed from
the shelf, but only if the shelf has been powerless during removal!
User defined data is not retained when the board is removed from the system.
- operation with battery back-up (normal operation):strap on position 101-102.
- operation without battery back-up (factory setting):strap on position 102-103.
When removing the KTLC from an operational system, remove and re-install the strap on
101-102 for about one second to clear the contents of the memory in order to avoid the
possible corruption of the user programmed data.
Note: When the board is stored the strap must be positioned on 102-103 to prevent a fully
discharged battery.
• Strap X3.1
The straps of X3.1 are used to select the correct transmission levels; the setting of X3.1
depends on the type of KTLC and the local transmission plan.
Tablegives the strap settings for the transmit levels; tablegives the settings for the receive
levels. Both tables indicate the strap settings per transmission plan for a few countries. For
countries not mentioned in the tables one should use the default settings of the KTLC;
these settings are:
- KTLC01 : the settings for the Netherlands.
24. 20
- KTLC02 : the settings for Germany.
- KTLC03 : the settings for United Kingdom.
Note: Make sure that the settings of X3.1 corresponds to the local transmission plan before
installing the board.
• Fuses
New KTLC types have 8 fuses (0.2 A, 8.5 Ohm) to give extra protection to the data
circuits. Fuse F1.1 belongs to the extension connected to the first output, F1.2 to the
second extension etc.

3.2. KTLC-A/E
The KTLC-A/E provides a 4-wire interface between up to 8 or 16 SOPHO SETs of the K series
(K160, K260, K261, K365) and the ISPBX. The a/b wires are used for voice; the c/d wires are
used for control information from/to the SOPHO SET.
The KTLC-A is an 8 circuit board, consisting of a single (mother) board. The KTLC-A is
delivered with an on-board memory backup battery.
The KTLC-E is a 16 circuit board and is a combination of the KTLC-A (mother board) and a
daughter board. KTLC-E does not have an on-board memory backup battery; the battery
cannot be fitted onto the mother-board if used as a KTLC-E.

Figure 3-5 Layout Front Connector FAB & FCC (on daughter-board)
The KTLC-A and KTLC-E have electronic 'automatic recovery' fuses, so no replaceble fuses
are used.
The transmission plan and the transmission levels are set by the software in the signalling
block. Refer to the Signalling Data Manual for further details concerning the meaning and
possible settings of the signalling group bytes.
The default value for the KTLC-A signalling block (2304) is transmission plan 01.
The on-board memory of the KTLC may contain user data. If a mains power failure might
29. 25
occur this memory has a back-up power supply via an on board battery.
• Strap X2.1
This strap is used to connect or disconnect the back-up battery of the memory circuits on
the KTLC board. With the battery connected these circuits retain user-defined data during
a system power failure.
User defined data is also retained when the board is removed from the shelf, but only if
the shelf has been powerless during removal!
In all other circumstances this strap has to be removed for a while before inserting the
board into the shelf. An example of such a situation is when removing the board with the
shelf powered up. The data stored in the on-board processor and associated memory is
mutilated in that case: the strap should be removed before re-inserting it so that the
processor and memory can be reset.
- Operation with battery back-up (normal operation):strap present;
- Operation without battery back-up (factory setting):strap not present.
• Strap X2.2
This strap must be placed (watchdog active)
• Strap X3.1
Strap 101-201 of X3.1 must not be placed; the board is then configured as KTLC-A.
The remaining straps of X3.1 must be placedfor normal operation; they are used for
factory testing.

4. DIGITAL LINE CIRCUITS
4.1. DLC-A/B/C/D
The Digital Line Circuit-A or B (DLC-A, DLC-B) provides a number of two-wire 2B+D
accesses to the ISPBX. Each access is a Philips proprietary Usinterface at a nominal bit rate of
152 kbit/s. The Usinterfaces can be used to connect terminal equipment, such as SOPHO-SET
S-range and LAMs. The DLC-A/B/C/D can operate in combination with a Line Driver Card
(LDC) when line powered terminals are connected.
The DLC-A controls a maximum of 3 DLC-Bs placed in the same Unit Group; the DLC-C
controls one DLC-D placed in the same Unit Group: controlling is done via frontcabling; see
figure.
The number of Usinterfaces of the DLC boards is:
- DLC-A : 3x(2B+D) Usinterfaces.
- DLC-B : 4x(2B+D) Usinterfaces.
- DLC-C : 7x(2B+D) Usinterfaces.

The DTX-I can replace a DLC-I or DTU-BA. When operating as a DLC-I or DTU-BA, only 7
circuits are used.
Note: There is also a stripped version of the DTX-I which provides 7 four-wire 2B+D S0
interfaces:the DTX-I (7).
Each line of the DTX-I has two straps of 3 pins which connect the power supply to the center
taps of the transmission line transformers for phantom power feeding purposes and for the
selection of master or slave, when used as a trunk connection; see the figure below.

System Ground
Figure 4-9 Meaning of strap X5.1 ... X5.30
The strap at the receiver side has the reference Rn and at the transmit side Tn: R stands for
receiver, T for transmit and n is the related line number.
When the DTX-I is used as a DTU-BA, the DTU-BA can operate either as Terminal
Equipment (TE) or as Network Terminator (NT) in a network. When changing over from TE
to NT (or vice versa) also the projecting data has to be changed. Check the projecting data to
see how the DTU-BA is projected.
• Strap Settings
Each circuit of the DTX-I can be used to connect:
- a terminal : connect, on Rn and Tn side, the straps 101&102 to
deliver the line power;
- a trunk line (TE side) : connect, on Rn and Tn side, the straps 102&103: no line
power, no sync. (=slave);
- a trunk line (NT side : on Rn and Tn side, no straps made: no line power, sync.
is delivered (=master).
When a DTX-I is projected as a DLC-I or a DTU-BA the following restrictions apply:
- A maximum of 7 lines (0 ... 6) can be used, even in case of a DTX-I(15);
- No mix of trunk and terminal circuits is allowed;
- The board is not downloadable.

DO NOT MOUNT A STRAP ON X2.1 AND X3.1. THIS WILL
DAMAGE THE PROCESSOR AND POWER SUPPLY.
• Terminal Equipment
When the DTU-BA is used as interface to the PSTN or another PBX it operates as a TE.
It expects to receive an external clock reference from an NT to synchronise with. This
means that a clock signal is available on frontconnector FC 101; this clock signal can be
used as the input clock for a CRU, when necessary.
• Network Terminator
When the DTU-BA is used as an NT, it operates as the master and it provides the
synchronisation clock for the TE. This means that no clock signal is available on front-connector
FC 101.
When two DTX-I (used as DTU-BAs) form one transmission link (max. distance 1000 meters)
one DTX-I must be strapped as DTU-BA NT and the other as a TE.

4.5. DTX-I(R)
The DTX-I(R) is the redesigned version of the DTX-I. The DTX-I15(R) provides 15 four-wire
2B+D accesses to the ISPBX. Each access contains an S0 interface which can be configured as
follows :
- as an extension interface (network side) to connect ISDN terminal equipment;
- as a trunk/tie line interface (user side) to make a connection to the ISDN.
Note: There is also a stripped version of the DTX-I(R) which provides 7 four-wire 2B+D S0
interfaces : the DTX-I7(R).
Strap Settings
Note that a strap summary is printed on the DTX-I(R) board between connectors FBA and
FBD. Each circuit of the DTX-I(R) can be used as :
- an EXTension to connect ISDN terminals
The straps must be placed on position 101&102 (factory setting).
The transmit and receive pairs of an interface are connected to -40 V and system ground
respectively, in order to power the connected terminals.
- a Trunk line
The straps should be parked in the position 102&103.
The transmit and receive pairs are isolated from -40 V and ground, in order to avoid high
ground currents flowing between two systems.

Front connectors
At the front of the DTX-I(R) four F122 connectors (FAB, FBA, FBD & FCC) are available to
connect the four-wire S0 interfaces. The pinning of these connectors is identical to the DTX-I.
Clock Reference
When the DTX-I(R) is used as interface to the PSTN or another PBX it operates as a slave
(TE). The PBX may need an external clock reference from the master network (NT) to
synchronise with. For this purpose a clock signal is available on front connector FC 101; this
clock signal can be used as the input clock for a CRU, when necessary.

4.6. DLX-U
The Digital Line eXtensions - Upninterface (DLX-U) provides 2 wire accesses for extensions
with Upninterface. There are two types: the DLX-U(15) and DLX-U(31).
The DLX-U(15) provides 15 accesses.
The accesses are 2B+D types which can be used in two different modes (the 'board type' and
the 'signalling group' in the projecting data determine the mode):
- 1B mode : This means that only one B-channel is applied and the second remains
unused.
- 2B mode : This means that both B-channels are applied.
The DLX-U(31) provides 31 accesses. The accesses are 2B+D types, but only one B-channel
is applied. This is called the 1B mode.
The circuits in relation to the lines differ per DLX-U and operating mode:
- DLX-U(15) in 1B mode:
circuit 0: PPU - DLX-U control channel (IMP)
circuit 1 ... 15: access 1 ... 15
- DLX-U(15) in 2B mode:
circuit 0: PPU - DLX-U control channel (IMP)

The Digital Line eXtension-Long line interface provides accesses for extensions with a Uk0
(2B1Q) interface.
The DLX-L provides 15 accesses with 2B+D interface of which :
- one B-channel is used (1B mode, Philips proprietary)
- two B-channels are used (2B, ITU compatible).
The mode depends on the signalling group and board type. Mixed mode (1B and 2B) on one
board is not possible.
The DLX-L has the following characteristics:
- It has Uk0 interfaces: a 2-wire, 98 ohms balanced, 2B1Q interface with a datarate of 144
kbits/s;
- On layer 3, it supports TMP, 1TR6 and Euro (ETSI): protocol selection on layer 3 is
automatic;
- It is able to support power to the terminals, nominal -58 volts with a current of 45 mA;
- It is intended to service voice and data terminals;
- When no Uk0 terminal is available, the board can be connected via a Private Network
46. 42
Terminator for Long lines (PNT-L), which converts the Uk0 (2B1Q) into an S0bus;
- Under optimal conditions, the DXL-L with a PNT-L supports a maximum line length of 3.5
km (0.4mm cable) or 5.5 km with 0.5mm cable (Filotex 0.5 cat.3).
The layout of the front connectors of the DLX-L is the same as for the DLX-U.
The LEDs on the board have the following meanings:
MEANING LEDs
Table 4-1 Meaning of the LEDs
• PNT-L
The PNT-L is a private network terminator that converts the Uk0 (2B1Q) 2-wire interface
provided by the DLX-L into a standard 4-wire S0bus. The use of a PNT-L for connecting
terminals to the DLX-L is necessary when no terminal with the Uk0 (2B1Q) interface is
available. The PNT-L is mains-powered and provides power to the connected terminal(s).
The interface between DLX-L and PNT-L is powered by the DLX-L. The PNT-L is
transparent for the layer 3 protocols (TMP, 1TR6 and Euro-ISDN).

5.1. ATU-SS
The ATU-SS (Subscriber Signalling) is a 2-wire line interface which connects the ISPBX system
to a PSTN. The a/b wires of the ATU-SS, when not interworking with a Metering Circuit (MC)
or Emergency Switch-over Unit (ESU), are directly connected to the MDF via front connector
FBC.
When the ATU-SS interworks with MCs and/or ESUs the a/b wires are, via a front connector,
first connected to an MC, MCE or ESU card and via that card to the MDF.
Note: Depending on the type of ATU-SS the card accommodates 4 or 6 ATU-SS circuits.

5.3. ATU-EM
The ATU-EM is a 2 or 4-wire line interface which connects the ISPBX system to another PBX.
The signalling used consists of two unidirectional 2-wire DC signalling links: the m/mm wires
for sending and the e/ee wires for the receipt of signals. There is no difference in signalling
between the 2 and 4-wire version.
All wires of the ATU are directly connected to the MDF via front connector:
- FBC:2-wire ATU-EM
- FAD:4-wire ATU-EM

5.3.3. ATU-EM-D
The ATU-EM-D is designed for special projects only.
This board serves as an interface between the SOPHO and equipment using a digital (64 kbit/
sec) interface as described in the ITU recommendations G703.1.
The board contains 4 circuits. The data channels are 4-wire for a co-directional connection (2
pairs: one in each direction) and 8-wire in case of a contra-directional interface (2 pairs for
data, one in each direction, and 2 pairs for timing signals, one in each direction). The signalling
is E&M signalling via separate E&M wires as is used on the ATU-EM boards. The
synchronisation can be extracted from the incoming data stream (circuit 0 only) or from the
special input connector on the board.
Strappings/connectors
shows the connector layouts. The strappings and the connector locations are shown in. The
connector/circuit relation is as follows:
Connector FAB Circuit 0 (data)

5.4. ATU-CH
The ATU-CH (Cailho Signalling) is a 2-wire line interface which connects the ISPBX system to
a PSTN. It is a symmetrical DC signalling, using phantom signals. The a/b wires are switched
in parallel and have the same polarity (earth or minus). The soil is used for the common earth
connection. The a/b wires of the ATU-CH are directly connected to the MDF via front
connector FBC.
When the ATU-CH interworks with MCs and/or ESUs the a/b wires are, via a front connector,
first connected to an MC, MCE or ESU card and via that card to the MDF.

a/b and c/d wires (4-wire).
- LKC and LKD select the source and terminating impedances.
- LKE selects the transformer DC current cancellation for 2-wire mode.
- LKF selects the duplexor circuit (hybrid) for the 2-wire mode.
- LKG selects the level adaptors for the 2-wire or 4-wire mode.
- LKJ and LKK serve for reversed connection of the polarized seizure detector, which is
necessary for correct functioning due to the cross connected a/b and c/d wires in the 4-
wire mode.
- LKH determines whether the pads for an unamplified line are included or not in the 4-wire
mode. For long line compensation or in case of an unamplified line the strap is absent,
otherwise present.

initialisation of the ATU-G is loaded from a ROM on the board.
In the table below the DIP switches are depicted. See figure for the location of the DIP
switches.
Note: The required signalling type and transmission plan can also be downloaded from the PPU
with PPU package 142 or higher. Then all 8 switches must be set to OFF
The ATU-Gs support transmission rates up to 19.2 kbits/s. Note that this figure depends
on other elements (e.g. the quality of the PSTN line). When higher rates are used, it is
advised to test thoroughly in advance.
