ARGUS 155
1 Introduction
1 Introduction
The Compact Allrounder
Combi tester for xDSL, Ethernet, ISDN and Triple Play
As a latest generation high-end combi tester, the ARGUS 155 contains an extremely
powerful ADSL/VDSL chipset that meets today's demanding technical requirements. The
ARGUS 155 is the only handheld tester and analyzer to integrate VDSL2 (all profiles),
ADSL (Annex A, B, J, L, M) and SHDSL (2, 4 and 8 wire), Ethernet, ISDN PRI/E1, 
BRI/S/T/U and POTS interfaces in a single measurement device - without having to swap
modules. 

GigaBit Ethernet Interface and Tests
Thanks to its Gigabit Ethernet interface (GigE), the ARGUS 155 achieves a download
speed of up to 200 Mbit/s with HTTP and FTP downloads, such as is already standard with
fiber optic modems (ONT) on the LAN interface. If the Ethernet cabling is faulty, the
ARGUS 155 can immediately locate the source of the fault by means of cabling tests via
the GigE interface. This makes it possible, for instance, to detect shorts, opens or
mismatches, but also the delay or polarity of the wire pairs, among other things.

SHDSL Interface
Flexible expansion capabilities mean that the existing interfaces can be extended with
additional functions, as required. For example, the SHDSL interface also operates in
SHDSL.bis as well as optionally in ATM, TDM or EFM modes.

Copper Tests (Cu Tests)
Copper tests (Cu tests) for physical line qualification without synchronization with the
DSLAM are always included. If necessary, these tests can also be considerably extended
in the field by simply connecting the new compact ARGUS Copper Box via USB, thus
enabling all important electrical parameters such as voltage, current, isolation resistance,
symmetry and manymore, to be automatically and quickly determined via tip, ring and
ground. The TDR (Time Domain Reflectometer) function makes it possible to measure line
lengths and trace sources of faults. A high-impedance connection enables a Line Scope to
display the time and frequency domains (FFT) in real time. The optional Active Probe II,
which is required for this, can be connected to an existing DSL connection and switched
between symmetrical and asymmetrical operation.

1 Introduction
Triple Play Quality and IPv6
The ARGUS 155 tests the quality of VoIP, IPTV and data services over xDSL and Ethernet
with optional Triple Play test functions. Thanks to its integrated handset, it can simulate not
only terminal equipment such as a telephone, PC or STB, but can also determine all
relevant quality parameters and evaluate voice quality according to the MOS method. It
tests IPTV suitability by means of a stream analysis, a VoD test, a channel scan or an IPTV
long-term analysis. Several of these IP tests can also be performed using the new, more
powerful IPv6 protocol.
Easy Operation
The large 320 x 240 pixel colour display and an intuitive menu structure, among other
things, guarantee user-friendly operation. A high-performance Li-Ion battery pack ensures
long operating times in the field.


Software updates can be downloaded to a PC free of charge and then loaded into the
ARGUS at any time. They are available at http://www.argus.info/en/service/downloads/.
Note:
Details on the use of the PRI interface can be found in the related separate
manuals.
You should find these manuals in the package with the delivered equipment. In
addition, you can always download the latest manuals from our website at 
http://www.argus.info/en/service/downloads/ or request them from our service
department.

1 Introduction
The Concept of the ARGUS Firmware User Interface
The ARGUS firmware presents - on a graphic Status screen - the results of tests made with
the latest in measurement technology. In this manner, all of the important processes can be
shown on a single screen together with main sequences with all the convenience and
transparence to which ARGUS users are accustomed.
In this manner - with its intuitive menu structure - the ARGUS makes it easy to not only 
configure, start and perform tests but also to examine the test results:
-
The physical layer - Layer 1 (e.g. DSL) - can be started and stopped completely
independently of the higher layers such as Virtual Lines (L2/3), services or tests.
-
Layer 2 (VLAN, VPI/VCI) and Layer 3 parameters (PPP, IP) are combined in 
independent Virtual Line profiles (VL profiles). Multiple VL profiles can be configured
and started on a single DSL access. It is also possible to bridge and route multiple 
Virtual Lines concurrently.
-
Thanks to the introduction of services between the Virtual Lines (VLs) and the Data,
VoIP and IPTV tests, it is now possible to take an incoming call even when the ARGUS
is used as an IP phone with VoIP activated.
You will find other important information about profile structures on our website.

Power management
In battery mode, the ARGUS will automatically power down after it has been idle for
5 minutes (this setting can be changed, see page 356). Reasonably enough, the
ARGUS will not power down during a test (e.g. Loopbox) or when it is in Trace
mode.
As an alternative, it is possible to operate the ARGUS using the included plug-in power
supply. When the power supply is connected, the accumulator is automatically
disconnected. Regardless of whether the power supply is connected, the accumulator
should always installed using the ARGUS. This will ensure, among other things, the
uninterrupted operation of the real-time clock.
Unplug the power supply from the mains, once the ARGUS is switched off and will
no longer be used (Battery charging).

ARGUS 155
7 Operation on an ADSL Access
Example: skew + bad contact

If a line is in good condition, the values will
fall as the frequency rises; for a very short
line, they will be nearly horizontal. In this
example, a short line is shown. The
upstream and downstream values from
the DSLAM and the downstream values
calculated by the ARGUS may sometimes
be skewed in the HLOG graphs. Other
times the DSLAM may not send the
upstream value of the HLOG or may even
send one that is false.
DSL connections are often possible even
though one of the two wire pairs is high
impedance or even open (with just
capacitive coupling). Such defective lines
commonly cause frequent interruptions
and/or loss of data. The following can
cause such problems: oxidized access
lines, bad contacts in the telephone
wallsockets, loose terminal clamps or
badly insulated lines. In such cases, the
attenuation on the line is higher for low
frequencies than it is for high frequencies.
This can be recognized by the unusual
relationship between the upstream and
downstream attenuation or nature of the
HLOG curve. Where the problem is
caused by one of the wires, the
attenuation is often lower for low
frequencies than for higher frequencies.
<Menu>
Example: Bridge tap
Opens the graphic functions 
(see page 46).
<Continue> ARGUS will return to the 
Bits/tone graphs.
The example at the side shows what is
known as a drop. This may indicate a stub
line (bridge tap).
Using the rule of thumb:
L[m] = 50 / f [MHz],
and knowing the frequency in MHz (in this
example 0.535 MHz), it is possible to
estimate the approximate length of the
stub line:
L [m] = 50 / 0.535 MHz = 93 m 
There is a stub line of approximately 93 m
in length.

7 Operation on an ADSL Access
The ARGUS determines the following ADSL connection parameters:
ADSL connection parameters:
ATM
The actual usable ATM bitrate in kbit/s.
Attainable ATM
This is the theoretically attainable bitrate in kbit/s.
Relative capacity
Utilization of the line as a percentage.
Latency mode
Depending on the configuration of the DSLAM, the ARGUS will
display either Interleaved or Fast.
Attenuation
The line’s attenuation in dB over its entire length and
bandwidth. Certain types of access are not suitable where the
line attenuation is particularly high. When considering the
attenuation values to determine the recommended access
types, it is better to use the dB values in the Hlog graphs with a
300 kHz cursor setting.
Output power
Output power in dBm referenced to 1 mW.
SNR margin
Signal-to-noise margin in dB The SNR margin is a measure of
how much additional noise the transmission can withstand and
still achieve a BER (Bit Error Rate) of 10-7. This value is the
amount of reserve that a line has to deal with interference. 
Rule of thumb: The SNR margin downstream should be at least
twice the SNR margin upstream or more.
Impulse noise prot.
The Impulse Noise Protection (INP) is an indicator of the quality
of the protective mechanism as far as impulse noise is
concerned. The number of DMT symbols, which can be
completely distorted in succession, without an error occurring
on the higher layers.
Interleave delay
This is the delay (in ms) caused by interleaving the data blocks.
FEC
Forward Error Correction
The number of transmission errors corrected using the cell
checkbytes.
f (far):
Errors that the DSLAM has detected and informed
the ARGUS.
n (near):

8.3 The ARGUS in the VTU-R Access Mode
Determining the VDSL connection parameters
The ARGUS is connected directly to the VDSL access (either before or after the splitter)
using the included xDSL cable or a patch cable. In this case, the ARGUS replaces both the
modem and the PC. The ARGUS will set up a VDSL connection and determine all of the
relevant VDSL connection parameters. The ARGUS displays the VDSL connection
parameters and saves them after the connection is cleared down if desired.

In general, the ambient temperature range found in the "Technical Data" apply to
operation on an SHDSL access page 16. However, even if the ambient
temperature is less than 50°C if the ARGUS is run in a high performance mode for
a long time, it is still possible that the protective features of the ARGUS described in "Warning and Safety Notes" (page 12) may still shut it down to
protect it against overheating.

selection
The clock setting depends the direction on the connection (transmitting
or receiving). In the case of synchronous clocking, the receive and the
transmit clocks are the same. Where plesiochronous clocking is used,
the two directions use different clocks. Bit stuffing is used to equalize
the clock differences. 
- synchronous 
- plesiochronous (TDM only)
- plesiochronous (NTR) (TDM only)
(The SHDSL clock will be derived from the Network Timing Reference)
Default setting: synchronous
Use the keypad to select the B and Z-channels. Up to 36 B channels
and up to 7 Z-channels can be selected. If an * is entered for the B and
Z-channels, the ARGUS will automatically determine the channel
assignment.

Wire pairs

The ARGUS always uses wire pair 4/5 (Line 1) for SHDSL 2-wire. In the
case of SHDSL n-wire, the ARGUS uses wire pair 4/5 1(Line 1) plus a
second wire pair (Line) from the list below. 
The order of the wire pairs can be changed:
- 2nd wire pair (Line 2) for 4-wire 
- 3rd wire pair (Line 3) for 6-wire
- 4th wire pair (Line 4) for 8-wire 
The wire pair 4/5 (Line 1), however, is always the master.

However, where necessary, the second, third and fourth wire pairs
(Lines 2 to 4) can each be marked and using the < > softkey on the left

can be moved down a position in the list or using the < > softkey on the

right can be moved up a position in the list. Please make certain that
you confirm your changes by pressing the
key to ensure that the
changes are accepted.
The following are the usual default (preset) settings: 

SHDSL 4-wire or the SHDSL 8-wire) banana plug cable or patch cable (n-wire). In this
case, the ARGUS replaces both the modem and the PC. The ARGUS will set up an
SHDSL connection and determine all of the relevant SHDSL connection parameters. The
ARGUS displays the SHDSL connection parameters and saves them after the connection
is cleared down if desired.
Use only the cable included in the package!

The ARGUS determines the following SHDSL connection parameters:
SHDSL connection parameters:
SNR margin
Signal-to-noise margin in dB. The SNR margin is a measure of
how much additional noise the transmission can withstand and
still achieve a BER (Bit Error Rate) of 10-7. This value is the
amount of reserve that a line has to deal with interference.
SNR
Signal-to-noise ratio in dB.
Attenuation (dB)
The line’s attenuation in dB over its entire length.
Output Power
Output power in dBm referenced to 1 mW.
CRC
Cyclic Redundancy Check
Number of all CRC anomalies (CRC6 checksum errors), also
known as Code Violations (CV). The ARGUS adds up the
number of CRC errors in the one-second periods.
LOSWS
Loss of Sync Word Seconds 
The number of seconds in which one or more sync word errors
occurred.
ES
Errored Seconds 
The number of seconds in which one or more sync word errors
occurred and/or one or more CRC anomalies occurred.
SES
Severely Errored Seconds 
The number of seconds in which one or more sync word errors
occurred or at least 50 CRC anomalies occurred.
US
Unavailable Seconds 
Number of seconds in which the SHDSL connection was not
available. At the latest after 10 SESs have occurred in a row, the
connection is no longer available. The 10 SESs are counted as
part of the time that the connection is not available. Once the
connection has become unavailable, it will first be considered to
available again after at least 10 seconds pass in which there are
no SESs. The 10 seconds without SESs are not counted as part
of the time that the connection is not available.

Autonegotiation / Ethernet Link Parameter
The default setting supports "autonegotiation" for the Ethernet link.
Setting: Autonegotiation "on"
When negotiating the link parameter, the ARGUS notifies the remote end that the following
are supported (these settings are fixed; they cannot be reconfigured):
- 10, 100 or 1000 Mbit/s (for details on 1000 Mbit/s, see the Gigabit Ethernet manual)
- half or full-duplex
- Flow control on / off (when on: sym. and asym. pause)
Manual setting of the Ethernet link parameter
Setting: Autonegotiation "off"
When "autonegotiation" is deactivated, the speed, duplex mode, flow control (flow control =
"Pause" mode) are set in the profile (see page 107).
- 10, 100 or 1000 Mbit/s, Default setting: 100 Mbit/s
- half or full duplex, Default setting: Full
- Flow control on / off (flow control is only reasonable when operating in full duplex)
Default setting: on
One-sided Autonegotiation
If a device which has autonegotiation enabled (on) attempts to connect to a
device on which autonegotiation is disabled (off) or not supported, no information
will be exchanged with the remote end. The speed will still be determined even without
autonegotiation by listening for NLP signals (10Base-T) or a 100Base-TX idle pattern 
(parallel detection). In this case, the device using autonegotiation will generally fall back to
half duplex (duplex mismatch is possible). This may lead to a conflict between the duplex
modes with "poorer" performance.

11 Virtual Lines (VL)
11 Virtual Lines (VL)
Virtual Lines (VL) are used to gather the settings for Layer 2 and Layer 3 into a profile - a
VL profile. These profiles can hold information about, for example, the protocols, VPI/VCIs,
VLANs and PPP data (in their own subordinate PPP profiles). With the aid of Virtual Lines,
it is possible to perform tests on multiple VPI/VCIs or VLANs and various protocols. 
Up to 20 Virtual Line profiles can be saved in the ARGUS. The settings in a VL profile, for
example, the protocol setting, can be edited. Regardless of the state of the physical layer
(Layer 1), the VL profile can be assigned to one or more services. 
Therefore, it is possible to run a data test (such as an IP ping test) and a VoIP test (like a
VoIP call) on the active access without having to setup Layer 1 (DSL, Eth) again - in spite of
the fact that the protocols are different.

11.2 Virtual Line Profile (VL Profile)
Explanations of the various types of profile:
Profile (1 - 20), see page 34:
- Under the access parameters, you will find the Layer 1 settings (Phys. parameters,
MAC address) and the assignments for the Data, VoIP, IPTV and VoD services.
- In addition to the access parameters, these profiles also hold the settings for the
Bridge/Router and the test parameters.
- Each profile can be assigned an individual profile name.
Virtual Line profile (Virtual Lines 1 - 20)
- These hold the settings for Layers 2 and 3.
- Virtual Line profiles are assigned to services.
- Each Virtual Line can be assigned to multiple services.
- PPP profiles can be assigned to the Virtual Line profiles.
PPP profile (1 - 20)
- These profiles hold all the data relevant for dialling.
- PPP profile are assigned to the Virtual Line profiles.
- Each PPP profile can be assigned to multiple Virtual Line profiles.

11 Virtual Lines (VL)
The relationship between the types of profiles
After all of the settings have been reset (see page 359), profiles (1-20) each have only one
Virtual Line profile (1-20) that is assigned to the Data service. Each Virtual Line profile 
(1-20) is assigned a PPP profile.
In this default state, none of the other services (VoIP, IPTV or VoD) are assigned a Virtual
Line profile or PPP profile. 
The assignment of other Virtual Line profiles and PPP profiles to services will be described
beginning on page 116.

11.3 Virtual Line Activation
In order to activate a Virtual Line, a service or test must first be started. In order to start a
test, a service must first be configured and assigned a Virtual Line. In this example, the
Data service has been configured and assigned a Virtual Line.
11.3.1 Starting a service
The ADSL connection is active.











Using the cursor keys, move from the
Layer 1 box over the Virtual Line to
the "Data" service.

If the physical layer is not yet
active, it will be started
automatically when the service or
test is started.

<Start> Start service
Now the physical layer (ADSL), the Virtual
Line, and the Data service are all active.
This is indicated by the green "check
marks".

service will be displayed.
<Config> Configure the settings of the
respective test (in this
example, IP ping).
For more details, see the
chapter on Tests (page 148).
11.3.2 Assigning additional Virtual Lines
The ARGUS can use multiple services (e.g. Data and VoIP) with a single Virtual Line. In
this example, ADSL is active. The Data service has been selected. In the following, we will
explain how multiple services can be connected using a single Virtual Line.

In order to configure a Virtual
Line (which is connected the
Data service in this example) for
use with other services, its
current service must first be
stopped.
The physical layer remains
active.


Use the cursor keys to
select the VoIP service.














In the next step, it is possible to activate
another service.
119
11 Virtual Lines (VL)


The "Data" and "VoIP" services are active.
It is now possible to perform various tests
on both the "Data" and the "VoIP" 
services.








The displays and operation of IPTV and VoD (Video on Demand) services are like those of
VoIP.
Other examples of different Virtual Line assignments:

Example 1:


One Virtual Line is connected to the Data
service and another to the VoIP service.
The Virtual Line for VoIP can use different
protocol data from that of the Virtual Line
for Data.








Example 2:

A Virtual Line was configured for the Data,
VoIP, IPTV and VoD services. 
In this example, the IPTV and VoD 
services are active.

In the case of the IPTV service it
is possible to setup up to four
Virtual Lines.
The ARGUS will however display
these together as a single Virtual
Line.
For more details, see the chapter
on IPTV (page 201).

In order for the ARGUS to perform these tests (with the exception of the ATM tests: VPI/
VCI scan, ATM OAM ping and Loop), you must first configure a Virtual Line. The confi-
guration of a Virtual Line is described in the chapter devoted to Virtual Lines, see page 111.

14 Loop
A loop can be setup on an SHDSL line (in EFM mode), as well as on an Ethernet line. A
loop will take all incoming Ethernet frames at Layer 1 (L1) and send them back to the
sender unchanged. 
In the case of a loop on Layer 2 (L2) of the OSI model, the ARGUS swaps the source MAC
address with the destination MAC address and then sends all the incoming Ethernet
frames back.

The following parameters are required for the Loop:

16.1 IP Ping
In the IP ping test, the ARGUS checks whether it is possible to setup a connection to an
Internet Service Provider (ISP) - or another computer or server address - via an Ethernet
connection (IP network) or via an xDSL connection (over a DSLAM and the ATM/IP
network): The ARGUS sends a test packet to a predefined IP address (remote site) and
then waits for a packet in reply. Based on the received packet, it is possible to evaluate the
ATM/IP network availability and delay. It is also possible to determine the path's maximum
data packet size. The following parameters are required for the IP ping:

Depending on the network (or router), test packets
may be divided into multiple packets.
off
Fragmentation is not permitted, i.e. the test packets
may be rejected by the network (or router). In this
case, the ARGUS will not receive a packet in reply.
auto
The ARGUS determines the maximum packet size for
the path to the destination address (Path-MTU) and
splits the test packet into smaller packets. These can
then be sent with the minimum of delay (since the
network/router need not fragment the test packet).

file. The ARGUS will display the current "net download rate", the user data of the IP
packets, and once the HTTP download is over the average speed (in the case of multiple
download attempts). The following parameters (which are stored in the profile) are required

A total of up to 10 user-defined server profiles can be created. These
server profiles will then be available for the HTTP download, FTP
download and the FTP upload tests. The profiles hold all of the
parameters required for the HTTP download, FTP download and the
FTP upload.
Server
address
Enter the IP address or URL of the server from which the ARGUS
should download the file. In the case of an Upload test: Enter the upload
destination (server address) to which the ARGUS should send the data.
For information on the softkeys, see page 149.
Download
filename
The name of the file that the ARGUS should retrieve in the download
test (HTTP download or FTP download). 
When entering a www address alias, please see page 163)
For information on the softkeys, see page 149.
Upload file
name
The filename under which the data – sent in the FTP upload test –
should be saved on the server.
Default setting: file
Upload file
size
Sets the size of the file that the ARGUS will send in the FTP upload test.
Range: 0 to 999 999 999 bytes
Default setting: 1 000 000 bytes
User name
Entry of the user name for the (FTP or HTTP) server.
For more information on the operation, see page 149.
Password
Entry of the password for the (FTP or HTTP) server.
For more information on the operation, see page 149.
Number of
up-/
downloads
The number of times that the ARGUS will retrieve the data from the
source address in a Download test. In the case of an Upload test: This
sets how often the ARGUS will send the data of the file to the
destination. "Zero“ means continuously. In which case, the test must be
terminated manually.
Range: 1 to 9 999 (0 = continuous)
Default setting: 3
Number of
parallel
downloads
The number of packets into which the requested download should be
divided and downloaded in parallel (see page 163). 
Range: 1 to 10 
Default setting: 3
Profile name Entry of a name for the profile
162
ARGUS 155
16 IP Tests
If an alias www address is entered as the "Source/Destination" address, the
ARGUS will "only" download the one HTML page during the HTML download
test. The ARGUS does not evaluate the HTML code, so any link to a “true” www
address will be ignored. In this case, the ARGUS will not display an error
message since the “Source/Destination” address specified will have been loaded
without error.

When entering the “Source” address (server address and download filename)
make certain that you use the correct notation (upper and lower case), otherwise
the ARGUS will report an Error 301 (Moved Permanently) or Error 404 (Not
Found).

If the ARGUS requests multiple downloads, it will reduce the number of
downloads requested to suit the number of downloads supported by the server.
This may result in a deviation from the parameters set. This can, for example, be
the case if the size of the requested file is unknown.
Where the name of the file to be downloaded exceeds the maximum permissible
length, it is possible to get around this by using the "Server" field for part of the
address.
The server name may be up to 80 characters long while the file name may be 60
characters long.

16.6 FTP Server
In FTP server mode, the ARGUS acts as a server for FTP requests. In this case, the
ARGUS will handle both FTP download and upload requests. 
These requests can be sent by a second terminal (e.g. a second ARGUS) on an xDSL or
Ethernet connection.
In this manner, it is possible to perform an end-to-end test of the throughput and determine
the highest average transfer rate attainable for this connection.

The throughput test is illustrated in the following on an Ethernet interface.
In this example, two ARGUS testers are used. One is used as an FTP server while the 
second requests an FTP download.

ARGUS 1 - FTP Server

No settings need to be made on the ARGUS that acts as the FTP Server. Simply start the
FTP server single test on the selected interface.

Start FTP Server (in the example: Ethernet is already active)


The profile shown on the display 

The ARGUS acts as a VoIP terminal with which a telephone (voice) call can be set up. The
ARGUS uses the Session Initiation Protocol (SIP) as the signaling protocol for VoIP. VoIP
calls can be set up with or without a registrar or proxy. The ARGUS can be used to setup a
VoIP connection (DSL telephony) via xDSL or Ethernet. The MOS/R-factor of the RTP data
stream will determined and displayed as an evaluation of the voice quality.
Three "VoIP accounts (Profiles)" can be configured for use in VoIP telephony:
Protocol-independent parameters:

However, pressing the "Cancel" key once will only clear down the connection (if
there is one). The ARGUS will remain registered with the registrar (VoIP service
active) so the ARGUS can still be called (an incoming call can be rejected or
accepted). Deactivate the VoIP service to clear the registration with the registrar. 
In this case, the existing connection will, however, not be cleared down.

18.4 Video on Demand (VoD)
In the VoD-STB mode, the ARGUS requests a data stream from a VoD server. Depending
on the type of access under test, the ARGUS replaces the STB or the modem and STB. 
VoD services are often made available via RTSP (Real-Time Streaming Protocol), which is
a control protocol that supports functions such as wind forward, rewind, pause etc.
Nonetheless, the ARGUS also supports the FTP, HTTP and MMS protocols. During the
test, the ARGUS checks the regularity of the incoming packets, the loss of packets, the
packet and PCR jitter as well as other possible errors. 
Depending on the preset thresholds, the ARGUS will display an OK/FAIL evaluation as well
as various important metadata of the received VoD stream. 
Up to three user-defined "VoD profiles" can be preconfigured (where a xDSL connection
has already been setup, the access parameters, e.g. the ADSL mode and the rated value,
are blocked):
Protocol-independent parameters:
ARGUS - Status screen.

19 Operation on an ISDN Access
If everything has been detected without errors, the ARGUS will display the type and mode
of access found. Additionally, a qualitative assessment of the level will be displayed.
The ARGUS will automatically determine the protocol (in both TE and NT mode) or use the
protocol set manually (see page 241 protocol). On a bilingual access, the ARGUS will use
the DSS1 protocol.

The "IP / L3" LED will light after the ARGUS has setup Layer 3. At the same time the
ARGUS will start a B channel test and then display the results. If an error occurs in the 
B channel test (e.g. access is not plugged-in), the ARGUS will display an error message
(see appendix). The ARGUS will then idle in the State display:

Default setting: Automatic
Alerting mode
You can specify whether, for an incoming call on a S-Bus point-topoint access, the ARGUS should only display the access number
without extension or the complete number with extension. When set
to "Manual", the ARGUS will display the extension. Incoming calls will
be signaled. When the ARGUS accepts a call, it will send the Layer 3
"Alert" message. The digits of the extension that have been sent by
this point will be displayed.
With the Manual setting, an incoming call must be
answered within 20 seconds or it will be lost.
Furthermore, you should note that the remote subscriber
will not hear a ringing tone.
If it is set to “Automatic”, the ARGUS will only display the
access number without extension or, depending on the
configuration of the access in the exchange, it may not
display the number called at all.
Default setting: Automatic
Clock mode
This parameter sets where the clock will be generated in the case of
a S-Bus access. You can either specify that the ARGUS generates

19.4 Bit Error Rate Test
The bit error rate test (BERT = Bit Error Rate Test) is used to check the transmission quality
of the access circuit. 

As a rule, the network operator will guarantee an average error rate of 1 x 10-7, in other
words in long-term operation 1 bit error in 10 million transmitted bits. A higher bit error rate
will be especially noticeable in transmitting data.

The application program detects the errors in the data blocks transmitted and requests that
the remote partner send them again, which reduces the effective throughput of the ISDN
connection.

In the bit error rate test, the tester establishes an ISDN connection to a remote tester 
(end-to-end) or calls itself (self call), sends a standardized (quasi-) random number string
and compares the received data with that which was sent. The individual bit errors are
summed and depending on the test procedure and equipment evaluated in accordance
with the ITU Guideline G.821.

During the test, the ARGUS counts the bit errors and after the test is done it calculates the
bit error rate and other parameters in accordance with ITU-T G.821.

As a rule, the quality of the network operator’s access circuits is quite good. Therefore, no
bit errors should occur in a one-minute test. However, if an error occurs, the test should be
repeated with a measurement time of 15 minutes to achieve higher statistical precision.
The access circuit is heavily distorted, if more than 10 bit errors occur within a test period of
15 minutes. 

Contact the network operator or the supplier of the PBX equipment and ask them to test
your access circuit.


When used on an NGN (Next Generation Network), where a packet switched
connection (e.g. IP) can follow a circuit switched network (e.g. ISDN), the
"UDI64k" must be explicitly selected for the BERT. Then the ARGUS will, in
accord with RFC 4040, switch to clear mode, deactivate the echo canceler and
not use a codec.

244
ARGUS 155
19 Operation on an ISDN Access
The BERT can be performed in three different ways:
1.
BERT in an extended call to oneself
A remote number is not needed, since the ARGUS sets up the ISDN connection to
itself. In this case, the ARGUS requires two B channels for the test.
2.
BERT with a loopbox
A loopbox (e.g. another member of the ARGUS family of testers at the remote end)
is required. The test uses one B channel.
3.
BERT end-to-end
This test requires a waiting remote tester (e.g. a second ARGUS in the "BERT wait"
mode)(see page 252, BERT wait). A bit pattern is sent to this remote tester.
Independent of the bit pattern received, the remote tester will use the same
algorithm to generate the bit pattern that it sends back. Therefore, both directions
are tested independently.

Explanation
BERT:
BERT time
You can use the keypad to enter measurement times ranging
from 1 minute to 99 hours and 59 minutes (= 99:59).
If the time is set to 00:00 (= BERT with unlimited
measurement time), the BERT will not stop
automatically. In this case, the BERT must be
terminated manually by pressing the
.
Default setting: 00:00 (continuous)
In the case of an Autom. Test (see Chapter 19.9 Automatic
Performance of Multiple Tests, page 272) the ARGUS will
automatically set this to a value of 1 minute.
Bit pattern 
S/T/U
This function is used to select the bit pattern to be sent cyclically
by the ARGUS to perform a BERT on a S-Bus or U interface
access. Several predefined bit patterns are available
Default setting: 211-1
Additionally, it is also possible to enter a 16 bit long pattern of
your choice in binary: Use the horizontal cursor keys to move the
cursor right or left.
<Delete>
Error level
Changes the digit before the cursor from 1 to 0
This is the level used to evaluate whether the BERT had an
"acceptable" bit error rate.
If the BERT has a bit error rate, which exceeds this error level,
the ARGUS will display a "NO" (Not OK) as the test result. 
Using the keypad, this parameter can be set to any value from
01 (= 10-01) to 99 (= 10-99). 
The default threshold (error level) is 10-06 (1E-06). That means
that, in the event that the bit error rate is less than 10-06 (one
error in 106 = 1,000,000 sent bits), the bit error rate test will be
evaluated as "OK".
HRX value
Setting the HRX value (Hypothetical reference connection, see
the ITU-T G.821). Using the keypad, you can enter a value
ranging from 0 to 100 %.

call, the ARGUS will display the corresponding error code (e.g. 28).
Example: The error code 28 equates to "wrong or invalid number". 
In the table below, you will find that this is an error from the network and that it reports that
the call number was incomplete or in the wrong call number format (see “ARGUS Error
Messages (DSS1)” on page 377).

ARGUS 155
19 Operation on an ISDN Access
There are PBXs that use separate call numbers for incoming and outgoing calls.
In this case, for the Service tests, you can enter a “remote” call number that does
not match the “own” number that is stored in the ARGUS. If the Service check
should extend outside of the local exchange, it is possible to perform the Service check in
an end-to-end mode. In this case, you must enter the remote call number for a second
terminal device. The ARGUS will then automatically check whether the remote terminal can
accept the call under the various services – in other words, whether it is “compatible” with
these services. In the test results, the second part (second +, - or *) refers to the answer
from the remote exchange.
Test results:
The ARGUS will display the results of the
test once it is done. The ARGUS makes a
distinction between outgoing calls (the
first +, - or *) and incoming calls (the
second +, - or *).
+ = suppl. service supported
= suppl. service not supported
-
= No definite assessment can be
*
made so an error code is displayed.
In such case, it is recommended that
you have someone place a call to
the access under test using this
service.

Scroll through the results
Close the results display and 
open the next higher menu.
Interpreting the test results:
Display Explanation
++
The self call functions OK or the remote end can take the call for this service.
+-
The call was sent successfully, however, it was rejected at the remote end due
to a lack of authorization.
-
An outgoing call with this service is not possible.
+*
The call was sent successfully, the call to the remote end failed (e.g. remote
end busy thus no B channel was available for the call back).
*
Wrong number, no B channel available or other error.
If the outgoing call is not successful, it is not possible to make a statement about an
incoming call. Therefore, you will never see “- +” or “- *” on the display.

19.7 X.31 Test
The ARGUS will perform a “Manual X.31 Test” or, if desired, an “Automatic X.31 Test”:
In the case of an automatic test, the ARGUS will first setup the D channel connection and
then an X.31 connection. The ARGUS will then automatically clear the connection and
display the results.

In the case of a manual test, the ARGUS will setup a D channel connection and an X.31
connection. The duration of this connection is determined by the user (or the opposing
end). For the duration of the connection, the ARGUS will repeatedly send a predefined data
packet. The ARGUS will count all of the data packets sent and received and will display
(where possible) the contents of the data packets received.

Automatic X.31 Test
D channel
The “automated X.31 Test in D channel“ consists of two steps:
First step:
The ARGUS tests whether it is possible to access the X.25 service via the
D channel on the ISDN access under test. The ARGUS sequentially
checks all the TEIs from 0 to 63. All the TEIs with which the X.31 service is
possible on Layer 2 will be displayed.
Second
step:
For each TEI with which X.31 is possible on Layer 2, a "CALL_REQ"
packet will be sent and then the ARGUS will wait for an answer.
Beforehand, the ARGUS will request the entry of the X.25 access number,
which will be saved in speed-dialling memory under X.31 test number (see
page 360). With the entry of the X.25 access number, you can - if you wish
- select a logical channel (LCN) other than the default.

Some PBXs or exchanges do not permit the use of the mechanism used (by the
ARGUS) for the interrogation of the call diversions for all MSNs or they return a
negative acknowledgement of the interrogation of call diversions, implying that no
call diversions have been set up. In the event of a negative acknowledgment, the
ARGUS will require that the local MSN is entered. The call diversion interrogation
will be repeated MSN-specific. Naturally, in this case, the results of the
interrogation of the call diversion only apply for the entered MSN and not for the
entire access.

The ARGUS performs an automatic test series and displays the test results. The required
parameters (e.g. measurement time and error level for the BERT, see page 245) should be
checked before the automatic test series is begun. 

Using the ARGUS WINplus or WINanalyse software, the test results can be saved on a
Windows PC. On the PC, WINplus / WINanalyse can be used to generate a
comprehensive report that can then be printed, sent by e-mail and/or archived. The
ARGUS automatically performs the following sequence of single tests:
On a BRI S/T or U-interface (ARGUS in TE mode)
-

-
Level measurement
-
Service check
-
BERT in an extended call to oneself
-

(DSP), the ARGUS will display the DISPLAY message's character string.
Note regarding the entry of the own call number
Separate the extension from the access number with a # (e.g. 02351 / 9070-40 is
entered on the ARGUS as: 023519070 #40). For an outgoing call, the ARGUS
uses the entire call number (without #) as the number called (CDPN or DAD) and,
for the calling number, only the extension (DSS1-CGPN).
A ‘#‘ at the beginning of a call number is treated as a valid character. A ‘#’ at the
end of the own call number instructs the ARGUS to not send the caller’s number for
outgoing calls (CGPN or OAD).

Incoming Call
An incoming call can be taken at any time even when a test (e.g. a BERT) is in process
(see page 289). The ARGUS will signal an incoming call with an audible tone and a
message on the display. On a P-MP access, you can use the Call acceptance (see page
243) function to configure the ARGUS to only signal incoming calls which are addressed to
the MSN that corresponds to your own call number. This function can only be used when
your own call number has been entered into the speed-dialling memory (see page 360) and
the incoming call has a destination MSN.

Testing Features via the Keypad
This feature is only relevant on an S-Bus or U interface. Some network operators do not
support the standard DSS1 features, rather they expect the user to control the network via
so-called keypad command sequences. In these cases, the desired facility is usually
activated by entering a series of characters and then sending these characters within a
DSS1-specific protocol element. These so-called keypad elements are imbedded in a
setup message. Each step is acknowledged either acoustically (handset) or via special
protocol elements (cause). These causes are displayed by the ARGUS.

19.15 Leased Lines on an ISDN Access
Besides dial-up connections to any subscriber, ISDN also supports the use of permanent
circuits switched to a specific remote location (leased lines). These leased lines
(permanent circuits) are available after setting up Layer 1, in other words after
synchronizing both terminals by exchanging HDLC-frames. The location where the clock is
generated can be selected (see page 241). A quick and simple test of a leased line can be
made by placing or taking a call on a selected B channel. However, for a more precise test,
a bit error rate test should be run.

Both ends of the leased line (permanent circuit) must use the same channel.

After selection of the channel to be tested (B channel or D channel), the ARGUS will send
the test pattern, receive it back and evaluate it accordingly.

The displays and operation are, in largest part, similar to those of a BERT on a dial-up

To provide objective evaluation of speech quality, the ARGUS will perform a PESQ analysis
in accordance with ITU-T P.862 (Perceptual Evaluation of Speech Quality) on an ISDN,
POTS, or xDSL access or on an Ethernet line directly. The PESQ test is only available for
the interface that was enabled earlier (e.g. ISDN option).
The ARGUS does not perform the PESQ analysis itself, rather it is handled by a PESQ
Server. This server has its own call number. The ARGUS is connected to the access under
test directly and sends or loops a standardized speech sample to the server.
To assess the speech quality sending, the ARGUS will send the recorded speech sample
to the server, which will determine the PESQ value and send this result back to the
ARGUS. The ARGUS will then display this PESQ result. 
To assess the speech quality sending and receiving, the speech sample will first be sent
from the server to the ARGUS which will then loop it back to the server.

In the Access Menu, you will find an entry for "Copper Tests". These tests are used to 
examine the physical properties of the line tested.
The use of the various functions is described briefly below. Since the results are generally
only presented in graphic form and as correct interpretation of the results also requires 
certain knowledge of the line measured, detailed instructions on the interpretation of the
results would spring the bounds of this manual. To facilitate interpretation of the results, the
ARGUS supports various aids, such as e.g. the Zoom and Cursor functions.
22.1 R Measurement
The ARGUS is first connected directly from the "Line" jack to the test points and then 

Line Scope ARGUS State Display
A variety of different conditions or events
on the access line can be examined with
the Line Scope. 
In this example, an ADSL (Annex B) 
connection has been set up between a
modem and DSLAM with an ISDN 
U interface.
The Line Scope is close to the modem,
since the upstream spectrum is 
particularly prominent. 
If the upstream was substantially lower
than the downstream, this would indicate
that the ARGUS was near the DSLAM.
<Menu>
Open the Graphic functions,
see page 329.
Besides determining the general condition
of the line or connection, it is also possible
to use the Line Scope to detect various
events. 
As an example, it can be used to see the
handshake tone that will be sent periodically by any modem which is connected to
the line when attempting to establish a
connection with the DSLAM. In this way, it
is possible to determine whether an active
modem is connected at the other end of
the line.

Furthermore, the Line Scope can not only be used to examine the DSL spectrum or handshake tones, it can also be used to detect objectionable, temporary interference (in realtime operation) or noise peaks rising out of the background noise.

Connection example:

Gain:
The optimum for detecting different signals is achieved by setting the gain (y-axis) and
reducing the frequency band shown (x-axis). In a frequency range up to 3 MHz, the
ARGUS will always begin with the lowest gain (-26 dB). 
Measurement range: -130 to +10 dBm/Hz.

Gain (Y): Setting the gain:
-26 dB, - 20 dB, 0 dB, 20 dB
The ARGUS will show all measurement results as dBm/
Hz values. These values can only be compared to each
other if the resolution of the frequency band examined
is taken into account, since in this case the entire
energy of the frequency band is determined as a "value
per Hz". The bandwidth currently examined by the
ARGUS is shown in the display as ∆f.

Frequency range:
Measurements can be made in a frequency range of 20 kHz to 30 MHz. The resolution
depends on the measurement range selected.


The ∆f, in the upper right of the display,

Example:
In a measurement range with a maximum

values can be displayed, therefore:
∆f = 32.768 MHz / 2048 values = 16 kHz.
Accordingly, the y-value marked with the
Cursor and displayed (in this example at

-133.3 dBm/Hz) of a frequency range
ranging from 16 MHz - ∆f/2 to 16 MHz +

The Line Scope display can be switched
from displaying the frequency on the 

this case, the ARGUS behaves like a 
normal oscilloscope capable of showing a
voltage range of 0 to 40 Vpp, on the y-axis
and having a resolution of 2 mVpp. 
In this mode, it is easy to recognize the
various AC voltages such as the square


The gain and time base can be adjusted as before (when displaying
frequencies) with the horizontal and vertical cursor keys.
The Cursor function is also available to measure the signal in the time
domain. However, there is no Zoom function.
If the ARGUS determines that the signal
regularly exceeds a certain threshold, it
will automatically attempt to trigger on this
signal so as to place it optimally in the 
displayed time domain.

22.4 Active Probe
The ARGUS Active Probe is an active high-impedance probe with which it is possible to
passively monitor an existing connection without noticeably disturbing it.

Nonetheless, in spite of the probe's high-impedance, it is possible that there
may be short interruption in the existing communications connection when the
probe is first connected.
The ARGUS Active Probes II are intended for use with the ARGUS Line Scope function.
The high-impedance Line Scope (input impedance 3.6 kcan also be used without the
use of the ARGUS Active Probes (see page 331).
22.4.1 Active Probe II
The specifications of the ARGUS Active Probe II are as follows:
- Input impedance: 70 k
- Input capacitance: < 1 pF
- Frequency range: 10 kHz to 30 MHz (±1.5 dB)
- Attenuation symmetrical: 14.5 dB
- 2 x 4 mm banana jacks (separation 12mm)
- Data transferred to ARGUS via an RJ45 cable (pins 4/5)
- Supply voltage: 5 V via ARGUS USB host interface and USB cable
The Active Probe II can be operated in "symmetrical" or "asymmetrical" mode. Using the
hotkey it is possible switch between these modes in the menu. Application examples,
see page 331, Line Scope.

22.4.2 Connect the Active Probe II
The Active Probe II is connected to the ARGUS's "Line" jack and its USB-A (Host) 
interface. The USB host interface of the ARGUS is used to supply the Active Probe with 
5 V. The Active Probe is then connected to access under test (this example shows an
Active Probe II connected on the line between the modem and DSLAM). The connection
should be made using leads as short as possible (< 5 cm).
Connection example:

The included leads and adapter have been purposely kept short. The leads
used with an Active Probe II should be kept as short as possible. In order to
attain the best measurement results, it is important that the Active Probe be
as close as possible to the line to be measured. Any extension of these
cables will increase the input capacitance of the Active Probe and may thus
corrupt the measurement results. Even the position of the two cables next to
each other may - the greater the distance that they run in parallel to each
other - falsify the results. If the Active Probe is used as delivered, the ARGUS
will automatically include the resulting additional attenuation when calculating
the measurement results.
22.4.3 Start Active Probe II (Line Scope as an example)

After a test has been started (in this 
example, Line Scope), the Probe menu
can be opened from the Graphic functions



If the Active Probe is activated and if it is
properly powered by the ARGUS, the
green LED will light on the probe.
It can take up to 10 seconds for
the probe to activate.

connected, a green checkmark will
appear in the lower right of the display
during the test.

22.5 TDR
Using the TDR function, it is possible to determine the line length in realtime and locate
sources of interference. Correct interpretation of the pulses displayed by the ARGUS will
allow detection of among others stub lines, bad contacts or short-circuits. In performing a
TDR, the ARGUS sends a pulse down the connected line and displays the returning
reflected pulse.
Any DC voltage on the access line may not exceed 200 VDC. Furthermore,
the line must be free of any AC voltages.
The result displayed of a TDR measurement may create the impression that
there are multiple disturbances on the line. It is advisable to clear the first
disturbance or fault and then run the test again. It is possible that the first
disturbance or fault caused one or more reflections and thus created the false
impression that the line has multiple faults. In many cases there is only one fault
on the line.
The ARGUS will generate a reflection at about 3 meters. To measure short lines
precisely and to avoid this reflection, we recommend the use of longer a
connecting cable e.g. one 5 m long.The pulse will still appear in the graph but by
using the longer connecting cable you can be sure that it is not from the line
under test.

propagation factor is the ratio between the velocity of propagation of the
pulse in the cable and the velocity of propagation of the pulse in a
vacuum (c0 = 299,792,458 m/μs). 
The pulse transit time delay for many wire types is also specified in V/2: 



The ARGUS will directly show the possible locations of faults on the 2-wire copper
line.
In the example, one sees that following
the input pulse (starting at 0 meters) a
second pulse rises at about 150 meters.
This could indicate that the line is open at
the end of 150 meters.

Analysis in greater detail is possible by
adjusting the range and gain and by using
the Graphic functions.



The optimum for detecting different pulse
reflections is achieved by adjusting the
gain (y-axis) and reducing/increasing the
range shown (x-axis).
The ARGUS always begins with the lowest gain (-26 dB) and a range of 1500
meters.



The TDR function will be in the State 







Using the pulse height and pulse width
settings, it is possible to adjust the shape
of the ARGUS's pulse to suit the line being
tested.
Setting the pulse


Height:
The pulse height sets the voltage level of the pulse that the ARGUS sends down the line.
The default value is 5 V, but the level can be adjusted to 20 V. As a rule, it is advisable to
increase the pulse height for longer lines. 
However, even if a line is short, if there is a lot of noise on the line it may be advisable to
increase the pulse height so that the reflection rises far enough above the noise to make
interpretation easier.

Width:
The pulse width sets the length of the pulse in nanoseconds (ns) that the ARGUS sends
down the line. The default pulse width is 500 ns; however, depending on the measured
range, this value can be increased up to a maximum of 2000 ns (2 μs). Like a higher pulse
a longer pulse carries more energy and is therefore mainly of use on longer lines. It must
be noted, however, that a longer pulse can also conceal important reflections and thus prevent correct interpretation of the TDR results.
344
ARGUS 155
22 Copper Tests
Wire types / VoP:


The absolute VoP value must always be
less than 1. It is, however, shown as a 
percentage on an ARGUS. In a cable with
a VoP (velocity of propagation factor) of
0.7, a signal will propagate at 70 % of the
speed of light (c0). 
The pulse transit time delay for many wire
types is also specified in V/2: 
V/2 = VoP[%] * 1.5. 
In the example, where the wire has a VoP
of 0.7 or 70 %, the V/2 would be equal to
105 m/µs. 
As an example, a typical patch cable has a
see page 339
VoP of 0.667 or 66.7%, which is the same
as a V/2 value of exactly 100 m/µs. When
attempting to precisely measure cable,
e.g. in a building, it is necessary to know and set the correct VoP value. The correct VoP of
a wire type can be determined using a cable that is of the same wire type, has a known
length, and which can be used as a reference before making the other measurements.

22.5.4 Examples
The following ideal waveforms may be of assistance to you in interpreting the reflected
pulse:

Examples:

Open cable
The reflected pulse is positive. No 
indication can be seen of adjacent 
disturbances or the remote end of the line. 






Short-circuit
The reflected pulse is negative. No 
indication can be seen of adjacent 
disturbances or the remote end of the line. 






Mismatch
Different cross-sections were used in the
line. The greater the mismatch, the greater
the amplitude of the reflection.





Bad junction point
A bad junction between lines produces an
"S" shaped reflection. The worse the 
contact, the greater the reflection.

346
ARGUS 155
22 Copper Tests
Stub line (Bridge Tap)
The beginning of a stub line is shown in
the form of a negative reflection which is
then followed - after a period corresponding to the line length to the end of the stub
- by a positive reflection if the stub line is
open at its end.
Inductance coils / Chokes
Inductance coils used on the line are optimized for the transmission of voice frequencies. They block DSL signals. The
first such coil on a line can be detected
using the TDR function. The reflection in
this case will be a positive pulse with a tail
trailing off towards the end of the line.
Faults after this inductance coil cannot be
detected.

Capacitance network
Like a short-circuit, a capacitance network
reflects the pulse in a negative form. 








Moisture
If moisture has gotten into the cable, it will
cause a reflection like that of a stub line.
The stretch between the negative and the
positive reflections will, however, be substantially more noisy than is usually seen
from a stub line.
ARGUS 155
347
22 Copper Tests

Loose contact
Real-time operation is the best approach
to locating a loose contact. The amplitude
of the positive reflection will vary as the
contact is shaken. 






Open shielding
The ARGUS can also be used to locate
the fault where the shielding of a line is
broken or open. In this case, connect one
contact of the ARGUS to the "a" and "b"
wires and the other contact to the line's
shield. The reflection will be like that of an
open line.
Correct line termination
If the line is properly terminated, the entire
pulse sent by the ARGUS will absorbed.
There will be no visible reflection.

24.5 Saving Call Numbers in the Speed-dialling Memory
Ten 24-place call numbers can be entered in the speed-dialling memory.
The first speed-dial number (displayed as "Own number") must be the call number
of the access under test (this is especially important for the automatic Service
check). In the Numbers menu, you can jump from the beginning of the list to the
end by scrolling up.
In the "Remote No. 1-8" memory locations, you can save remote call numbers. In the "X.31
test number" memory location, the ARGUS expects the entry of the X.25 access number
for the X.31 test (see page 260).


Numbers
Scroll to the desired location in
the speed-dialling memory. Enter
the number via the keypad.
Enter the phone number
<Delete>
The ARGUS
saves the number and returns to
the next higher menu.
If the cursor is to the right of the
last character, this character will
be deleted. Otherwise, the
character that the cursor is on will
be deleted.
The ARGUS will return to the
next higher menu without saving
the number.
When entering an own call number with an extension (operation of the ARGUS on
a PBX access), observe the following: The extension is separated from the access
number by a "#". For outgoing calls, the ARGUS uses the entire call number
(without a "#") as the number called (CDPN or DAD) and, for the calling number
(DSS1-CGPN), only the number after the "#", in other words the extension. A "#" at
the beginning of a call number is treated as a valid character.

Example: 02351/9070-40 is entered as 023519070#40

If the "# " is at the end of a number, when the number is later dialled it will be done
without CGPN or OAD.This is important for some PBXs.

25 Using the Battery Pack
25 Using the Battery Pack
Changing the battery pack
Switch the ARGUS off and disconnect the plug-in power supply. Afterwards, loosen the
thumbscrew to release the battery pack.
Battery pack handling
The ARGUS may only be operated with the included battery pack. Connecting any
other voltage supply to the contacts in the device will damage the ARGUS.
-
The supplied battery pack may only be charged in the ARGUS.
-
Do not use the supplied battery pack in other devices.
-
The ARGUS battery pack may only be actively charged (Charge battery) or trickle
charged (default setting: on) when the ambient temperature is between 0 °C (32 °F)
and +40 °C (104 °F).
-
Recharge the battery pack fully at least once a month (even if the ARGUS is not used
for a longer period of time).
-
If the lithium-ion battery pack is stored, it should first be charged to between 40 and
60 % of its capacity. If the lithium-ion battery pack is stored for a longer period of time,
it should be recharged to this level every six months.
To maximize the service life of a battery pack, if it is to be stored over a longer period
of time, it should not be exposed to temperatures in excess of +50 °C (95 °F).
-
Please read the extensive notes on safety and the transport of the lithium-ion battery
pack found in the section "Safety Instructions" (see page 12).
Automatic recharging of the battery pack when the ARGUS is switched off
The ARGUS automatically recharges the battery pack, if the ARGUS is connected to the
plug-in power supply and is switched off and the battery pack voltage is too low. While
charging, the ARGUS displays the message “Charge battery”. If you press and hold the
power switch, the ARGUS will switch off before the battery pack is recharged. The ARGUS
remains on after fully recharging the battery pack.
ARGUS 155
361
25 Using the Battery Pack
Charge battery
The ARGUS will display the current charge of the battery pack graphically, if no power
supply is connected. A battery symbol on the display will begin to blink, when there is still
approximately (depending on the mode of operation) 8 minutes reserve. During this period,
it is possible that there may be audible interference and in rare cases even malfunctions.
Connect the power supply.
When the plug-in power supply is connected, the battery pack in the ARGUS can be fully
recharged. It is not necessary to manually discharge the lithium-ion accumulators in the
ARGUS battery pack. It may take up to 6 hours to fully recharge the battery pack.


If the ARGUS is disconnected from the power supply before the battery pack is fully
recharged, the ARGUS will not automatically begin to charge the battery pack
again when it is reconnected to the power supply, since the battery voltage is no
longer less than the threshold value.

26 Firmware Update
After you have selected the type of device, the page showing the relevant firmware updates
will open. On this page, you can select the firmware variant for your specific country.
After you have selected the required variant, a browser window will open to permit you to
select the location where the firmware should saved on your PC. The remaining steps are
explained in the WINanalyse manual and in the guide for the Update Tool
Important information regarding the ARGUS Firmware Update:
Do not, under any circumstances, start to update the firmware if the ARGUS is
running on its battery pack. First connect the ARGUS to the plug-in power supply,
before sending the firmware update file from your PC to the ARGUS. An ARGUS
USB cable is required to perform an update (USB cable with a mini-USB plug).
Save the configuration and test reports on a PC before beginning an upgrade. Do
not disconnect the ARGUS from the PC during the update. Do not switch the
ARGUS off while an update is being performed. You must also pay attention to the
messages on the ARGUS display – not just the instructions displayed by the
Update Tool on the PC. The update has not been successfully completed until the
Update Tool displays a corresponding message on the PC and the ARGUS – after
being automatically restarted by the Update Tool – shows the normal startup
screen.
The ARGUS will not switch on until after you have clicked on one of the two
buttons ("back to step 1" or "Exit program") on the Update Tool after the update
has been completed.
