ARGUS 42 PLUS
1 Introduction
1 Introduction
The ARGUS 42 PLUS provides support for setting up ADSL accesses. It supports
measurement of the up and downstream line parameters and can, depending on the
version, be used for both ADSL-over-POTS (analog) and ADSL-over-ISDN. In addition, it
can be used as a POTs and ISDN tester. Thanks to its range of features, this single tester
can handle all of the important customer interfaces. Besides the automatic test routines for
the various types of access and protocols, the ARGUS 42 PLUS also measures the quality
of the line as well as the maximum possible transmission speed and thus simplifies the job
of correctly setting up an access.

Access tests can be saved in the ARGUS 42 PLUS and later transferred to a PC. The line
parameters are presented on the display. Furthermore, the ARGUS 42 PLUS can be
expanded with optional IP ping functions, a bridge mode and router mode to add support
for testing Internet connections. With these options, network operators can use it to
exchange data packets with the Internet provider to determine the transmission quality. In
such a case, a download test is also available. Furthermore, the tester can also be used to
run tests on Ethernet interfaces or to measure the resistance and capacitance on a
subscriber's line as well as to detect certain frequencies on the line.

The ARGUS 42 PLUS can also be upgraded to a complete voice tester if desired. Using its
handset, it is possible to set up voice calls to test and evaluate connections on not only
POTS and ISDN, but now also for calls placed via VoIP. The test results will be shown in
the display. In such cases, the ARGUS 42 PLUS determines the MOS value for the
connection and evaluates it, as well as delivering other detailed measurements. 
It is also possible to determine the Media Delivery Index (MDI) in accordance with RFC
4445.
Thanks to the intuitive, easily understood menu system, which permits among other things
easy configuration and the storage of various profiles, it is simple to operate. It is also easy
to connect a headset, 

Furthermore, if you want to extend the ARGUS 42 PLUS operating time, you can use an
additional battery pack. With the standard battery pack, the tester weighs 425 g.

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.

Charging the accumulators for the first time
The battery compartment for the three accumulators (rechargeable batteries) and the
connector for the optional battery pack are located on the back of the case. Unscrew the
screws to remove the cover of the case and insert the accumulators in accordance with the
polarity marking. Use only the accumulators included in the package. The battery pack is
plugged into connector on the back of the case and fastened to it with a screw. With the
ARGUS switched off, connect it to the supplied plug-in power supply.
Press the

Power Management
In accu/battery operation, if the ARGUS is idle for 5 minutes (default), it will
automatically switch to the power-down mode (power-down). The ARGUS will
remain in power-down mode until the Power-Key is pressed again. Reasonably
enough, the ARGUS will not enter power-down mode 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 power supply. If
the ARGUS is connected to the plug-in power supply, it will automatically disconnect the
accumulators and will not enter power-down mode. You should only operate the ARGUS
with the accumulators installed. This will ensure among other things the uninterrupted
operation of the real-time clock.
Power Management settings:
If desired, the settings recommended for the times may be changed. In this case, the
settings for the automatic power-down and for the display lighting may be set separately.
Settings under: "Menu\Configuration\Device\Power management"
Caution! If you change the recommended (default) settings, this may lead to
shorter battery operation!

The ARGUS uses the access parameters stored in the profile when setting up the
connection (see page 40).
The ARGUS may need a few seconds to record all of the parameters. To be
certain that all of the parameters have been recorded, simply examine the Bits/
Tone or SNR/Tone graphs. If the ARGUS can display these, it must have also
recorded all of the rest of the parameters. 
If the test is terminated too early (right after synchronization), it is possible that
some of the important parameters will not be included in the test report.

7.3 Autonegotiation / Ethernet Link Parameter
The Ethernet link "autonegotiation" is supported by the default setting.
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 and 100 Mbit/s
- Half and full duplex
- Flow control on / off (when on: sym. and asym. pause)
Manual setting of the Ethernet link parameter
When "autonegotiation" is deactivated, the speed, duplex mode, flow control (flow control =
"pause" mode) are set in the profile (see page 66). The ARGUS the following can
configured:
- 10 and 100 Mbit/s
- Half and full duplex
- Flow control on / off (flow control is only reasonable when operating in full duplex)
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 (10 Base-T) or a 100 Base-T
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.

Default setting: 4
Profile name
Entry of a name for the profile

If an alias www address is entered as the "Source" 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” address specified will have been loaded without error.
Since it is not possible to accurately determine the transmission speed if the
duration of the download test is less than 10 seconds, you should download a
reasonably large file. 

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. 

10.1 VoIP telephony
On an ADSL or Ethernet access, 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. Using this protocol, the ARGUS can be used peer-topeer operation (direct, address based) or with a registrar (proxy, SBC or similar). 
The user can individually configure three “VoIP Profiles” for use in VoIP telephony (for more
information, see page 96): the profiles can be opened – to view and edit – from the
Configuration menu. If a connection is currently set up, the ADSL access parameters 
(e.g. the ADSL mode) will be write-protected.

12.2 Initialization Phase Including B-Channel Test:
Initialization on a BRI S/T or U-interface access
The ARGUS will setup Layer 1. While Layer 1 is being setup, "L1" LED over the display will
blink. If the ARGUS cannot setup Layer 1, it will display the message “No Net”. When the
ARGUS is operated on a U-interface, it can take up to 2.5 minutes to activate Layer 1. As
soon as Layer 1 is successfully setup, "L1" LED will light continuously. Once Layer 2 has
been setup, the "L2" LED will light.
If both modes (P-P / P-MP) are found when Layer 2 on the D-channel is checked,
the mode must be selected manually.

If everything has been correctly detected, 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 or use the manually selected protocol
(see page 117). On a bilingual access, the ARGUS will use the DSS1 protocol.

LED L3 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 either repeat the initialization or show an error
message (see page 200). The ARGUS will then show the Status display.

Protocol
As an alternative to automatic protocol determination, you can also set
the Layer-3 D-channel protocol manually. This setting will be stored
permanently and will also active when the tester is switched on again.
Default setting: Automatic
Alerting mode
You can specify whether, for an incoming call on a BRI point-to-point
access, the ARGUS should only display the access number without
extension or the complete number with extension.
If it is set to “Manual”, the ARGUS will display the extension (An
incoming call will be signaled. The ARGUS will send the Layer 3
message “Alert” when it accepts the call. The digits of the extension
that have been sent by this point will be displayed.).
When using 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
Call parameter On the user-side (ARGUS in TE mode), four different parameters can
be set for a call setup (in ISDN):

12.4 Bit error rate test
The bit error rate test (BERT = Bit Error Rate Test) serves 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 or
places a call to itself, 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 G.821. Two B-channels are needed
at the same time for this bit error rate test. 

As a rule, the quality of the network operator’s access circuits is quite good. Therefore, no
bit errors should occur in a 1-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.
In the case of an NGN (Next Generation Network), where a packet-switched
network segment may follow a circuit switched one, please explicitly select "UDI
64k" as the service 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.

The BERT can be performed in three different ways:
ARGUS 42 PLUS
119
12 Operation on an ISDN Access
1. BERT in an extended call to oneself
A remote number is not needed, since the ISDN connection is set up to oneself. 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 such as an ARGUS in the BERT wait mode
(see page 126). A bit pattern is sent to this tester. 
Independent of the received bit pattern, the remote tester uses the same algorithm to
generate a bit-pattern that it sends back. Therefore, both directions are tested
independently.

The default settings can be restored at any time (see page 184). The procedure for
configuring a parameter is the same for all parameters and will be illustrated with a single

This setting determines the bit pattern that the ARGUS will
repeatedly send in a BERT. Several predefined bit patterns are

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" 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) level is 10-06. 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.

The ARGUS tests the TP (Terminal Portability) supplementary service by
making a self call.
HOLD
The ARGUS tests the HOLD supplementary service by making a self call.
CLIP
The ARGUS checks, one after the other, whether the 4 supplementary
services CLIP, CLIR, COLP and COLR are supported. To do so, the ARGUS
will setup as many as three calls to itself.
CLIP:
Will the calling subscriber's number be displayed at the called
subscriber?
t = CLIP temporarily available
p = CLIP permanently available
CLIR:
Will the display of calling subscriber's number at the called
subscriber be suppressed or is it possible to temporarily suppress
the display? If the ARGUS displays an *, it is not possible to
determine the availability of the service, since no CLIP has been
setup.
t = CLIR temporarily available
p = CLIR permanently available
COLP: Will the call number of the subscriber who answered be displayed on
the caller's phone?
COLR: Will the display of the call number of the subscriber who answered
be suppressed on the caller's phone or is it possible to temporarily
suppress the display? If the ARGUS displays an *, it is not possible
to determine the availability of the service, since no COLP has been
setup.
The suppl. services CLIP, CLIR, COLP and COLR will be tested in pairs. If
CLIR or COLR is set up permanently, it is not possible to make a clear
assessment.
DDI
Can a caller directly dial in to an extension on the PBX access under test?
MSN
Is the supplemental service MSN supported?
CF
The ARGUS will check whether the 3 supplementary services CFU, CFB and
CFNR are supported.
CFU:
Can this access immediately forward an incoming call?
CFB:
Can this access forward an incoming call when it is busy; in other
words does it support Call Forwarding Busy?
130
ARGUS 42 PLUS
12 Operation on an ISDN Access
CFNR: Can this access forward an incoming call when it is not answered?
In the CF test, the ARGUS attempts to set up a call diversion to the call
number that is in the speed-dialing memory location for “remote call number
1” (see "Saving call numbers in the Speed-dialing Memory" on page 24).
When performing a CF test, the ARGUS will report an error if this location
does not contain a valid call number to which it is possible to divert a call.

For this test, you need the assistance of a remote subscriber, whose call
number must be entered. A connection is necessary.
ECT
Is an explicit call transfer supported by the access under test? 
For this test, you need the assistance of a remote subscriber, whose call
number must be entered. A connection is necessary.
CUG
The ARGUS then uses a self call to check whether the access under test
belongs to a closed user group.
CD
An incoming call will be diverted immediately. This form of call diversion
differs from the others in that it is invoked on a call-by-call basis, and is not
preconfigured to a specific destination.
AOC
The ARGUS checks whether the charges can be sent to the access under
test. The test uses a call to oneself to check both AOC-D (AOC during a call)
and AOC-E (AOC at the end of a call).
SUB
A call is made to oneself and answered to check the transfer of the subaddress in both directions.
Are sub-addresses supported on the access under test?
UUS
Does the access under test support the transfer of user data?
No
If the caller supports CLIP No Screening, all of the net-side call numbers
Screening connected with the ARGUS will be displayed.

Supplementary Services Test - Error Messages
If an error occurs during the Supplementary Services Tests or if it is not possible to setup a
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 "CAUSEMessages – DSS1 Protocol" in the appendix).

For each service, the ARGUS will place a call to itself (to
the access under test). However, the call will not be
answered so no charges will be incurred.
133
12 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 test should extend outside of the local exchange, it is possible to perform the
Service test 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.
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 *).


Fax G4 service is supported in both directions.


If an error occurs (See “Supplementary Services Test - Error Messages” on page 132) the

12.7 X.31 test
The ARGUS will either perform a “Manual X.31 test” or an “Automatic X.31 test”:
The ARGUS will first perform a TEI test and then begin to setup an X.31 connection.
Afterwards, the ARGUS will 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.
Two different parameters can be set for the X.31 test:

X.31 test, automatically (D-channel)

The "Automatic X.31 test" is performed in two steps:

First Step:
The ARGUS tests whether it is possible to access the X.25 service via the D-channel on
the BRI S/T access under test. The ARGUS checks all of the TEIs from 0 to 63 one after
the other. All the TEIs, which support X.31-service 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 ”Reset all parameters" on page 184). 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 acknowledgment 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, therefore, request
that the own MSN be 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.

Separate the extension from the access number with a # (e.g. 02351 / 9070-0 is
entered on the ARGUS as: 023519070 #0). 
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 or 1TR6-OAD).
A ‘#‘ at the beginning of a call number is treated as a valid character. A ‘#’ at the

12.11 Testing features via the keypad
This feature is only relevant on a BRI S/T access.
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 socalled 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.

When switching the load levels, the power limitations of the components within the ARGUS

consideration. Therefore, the ARGUS will only permit the load to be switched another
increment when the specified voltage will not be exceeded.

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.
As a quick test of a leased line, you can simply call the opposite end 
using a selected B-channel. However, for a more revealing test of a leased line, you should
perform a bit error rate test.

Both ends of the permanent circuit (leased line) must use the same channel.

resistance test shows that the line is open (infinite
resistance), the ARGUS will begin the capacitance
measurement.

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 #) as the number called
(CDPN or DAD) and, for the calling number (DSS1-CGPN or 1TR6-OAD), 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: 02351/9070-0 is entered as 023519070#0
If the “# “ is at the end of a number, when the number is later dialed it will be done
without CGPN or OAD. This is important for some PBXs.

18 Use of accumulators and battery packs
18 Use of accumulators and battery packs
Replacing the accumulators
Switch the ARGUS off and disconnect the plug-in power supply. Afterwards, remove the
complete set of accumulators or replace the battery pack (see page 25).
Accumulators - Usage
The accumulators used in the ARGUS must have the same capacity and be
charged to the same level. To ensure that this achieved, you must observe the
following rules: 
Accumulator set
-
The supplied accumulators must only be charged and discharged in the ARGUS.
-
Do not use the supplied accumulators in other devices.
-
Do not use accumulators with differing capacities or ones that are not equally
charged.
-
Order a complete set of new accumulators from the manufacturer and use these to
replace the complete set of old accumulators. After you have replaced a set of
accumulators, they must be fully charged in the ARGUS before use.
-
The accumulators should not be exposed to very high or low temperatures any
longer than necessary.
-
Discharge and recharge the accumulators fully at least once a month (even if the
ARGUS is not used for a longer period of time).
-
When the capacity of the accumulators decreases, replace all of the entire set.
-
Do not use batteries.
Battery pack (accumulators)
-
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 accus) or trickle
charged (default setting: off) 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).
-
To maximize a battery pack service life, if it is to be stored over a longer period of
time (> 1 year), it should not be exposed to temperatures in excess of +35 °C 
(95 °F).
-
Please read the extensive notes on safety and the transport of the battery pack
found in the section "Safety Instructions“.
186
ARGUS 42 PLUS
18 Use of accumulators and battery packs
Automatic recharging of the accumulators when the ARGUS is switched on
The ARGUS automatically recharges the accumulators (often shortened to "accus"), 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 accu”. If you
press and hold the power switch, the ARGUS will switch off before the accumulators are
recharged. Once the accumulators are charged, the ARGUS display "Done" and - if no
errors occurred while charging - will automatically switch off.
Charge accus
The ARGUS will display the current charge of the accumulators graphically, if no power
supply is connected. In the LCD display, a battery symbol will begin to blink, when there is
still approximately (depending on the mode of operation) 5 minutes reserve power. During
this period, it is possible that there may be audible interference and in rare cases even
malfunctions. Connect the power supply.

When the power supply is connected, the accumulators in the ARGUS can be completely
discharged or immediately (without being first discharged) recharged. The discharge
procedure takes up to 7 hours. The ARGUS will automatically begin recharging the
accumulators after a break of about 30 minutes (depending on the capacity of the
accumulators, it can take up to 7 hours to recharge them).

18 Use of accumulators and battery packs
Automatic recharging of the battery pack during operation (trickle charge)
"Accu servicing during operation" does not replace "normal" charging, since the
ARGUS will only top up the current charge with a trickle charge. 
If the ARGUS is disconnected from its power supply, it is possible that the
accumulators may not be fully charged. In such case, when the ARGUS is
reconnected to the power supply, it will not begin to charge the accumulators again
until their voltage drops below the threshold once more. 
If the ARGUS is switched off during "Accu servicing during operation", it will switch
back to "normal accu charging" (see page 187 Automatic recharging of the
accumulators when the ARGUS is switched on).

voltage drops below the threshold (display shows battery
symbol).

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.

The ARGUS USB serial adapter is required in order to perform an update. Save
the configuration and test reports 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.
