1 Introduction
1 Introduction
The VDSL+ADSL universal test set
The ARGUS 142 tests VDSL2, ADSL, Ethernet and ISDN (BRI S/T and U interface) and
POTS as well - with no module swapping. This convenient universal tester with a colour display integrates all those interfaces into a single device. Separate chipsets for ADSL and
VDSL2 ensure optimum performance.

Lineman’s handset for POTS, ISDN and VoIP

In addition to its functionality as an analog butt set and as a complete ISDN tester, it also
offers support for testing VoIP via ADSL and VDSL interfaces and Ethernet. Besides simulating a terminal, it also offers extensive statistic functions and evaluates voice quality in
accordance with the proven MOS technique. 

Download, MDI, VoD and IPTV test set

In addition, the tester includes support for determining the Media Delivery Index (MDI) and,
when it is used to simulate a set-top box (STB), the ARGUS 142 can also be used to assess
IPTV and Video on Demand data streams. The ARGUS 142 can be also well equipped for
checking Internet connections as it has IP ping and download test functions.

Long-term analysis & copper test set
Rounding out the package, it can operate in bridge and router mode and can also perform
an IPTV or ADSL online trace when it is used together with WINanalyse. Resistance and
capaci-tance measurements are available to check the physical characteristics of the
subscriber’s line. In view of the above set of features, it is obvious that the ARGUS 142
offers a range of measure-ment functions for use on various interfaces. Nonetheless, this
set of features has been packed into an extremely small and handy device; one that is
compact to use on location - wherever that location might be - but also ready for use in no
time.

Easy operation
The ARGUS 142 is also extremely easy to use. It has a large (320 x 240 pixels) colour
display, uses softkeys and has not only a USB client but also a USB host interface. The
tester uses a high-powered, long-life Li-Ion battery pack.
Software updates can be downloaded to a PC free of charge and then loaded into the
ARGUS at any time. They are available at www.argus.info/en/service.

2 Safety Instructions
2 Safety Instructions
The ARGUS may only be used with the included accessories. Usage of other accessories
may lead to erroneous measurements and may even cause damage to the ARGUS and the
connected installation. The ARGUS is only to be used in accordance with the instructions in
this documentation. Any other usage may result in bodily injury and destruction of the
ARGUS.
-
Before connecting the ARGUS to an access make certain that the voltages on the
access are not high enough to be dangerous or outside the specified range of the
ARGUS or its accessories. You must also taken into account the fact that the
voltage may vary while the ARGUS is connected to the access.
-
Regardless of the interface or access, use the ARGUS only for its intended
purpose.
-
Voltages in excess of 50V AC or 120V DC can cause mortal injury.
-
Never attempt a measurement with the case open!
-
The ARGUS is not watertight. Protect the ARGUS from exposure to water!
-
Before replacing the battery pack, disconnect all the test leads and switch the
ARGUS off.
-
Unplug the power supply from the mains, once the ARGUS is switched off and is no
longer in use (for example after recharging the accumulators)!
-
The ARGUS may only be used by trained personnel.
In connection with the lithium ion battery pack, please observe the following notes
regarding safety and transport.
Return and environmentally acceptable disposal
The RoHS (EU Directive on the “Restriction of Hazardous Substances”) guidelines, which
restrict the use of certain hazardous substances in electrical and electronic equipment,
apply in eight of the ten categories of the WEEE (EU Directive on “Waste Electrical and
Electronic Equipment”) guidelines. Devices which are in Category 9 “Monitoring and
Control Instruments” are currently excluded from the scope of the Directive. The ARGUS
products fall into Category 9 and are thus not subject to the RoHS guidelines. Nonetheless,
we have voluntarily complied with all of the RoHS guidelines since 1 January 2007.
In compliance with WEEE 2002/96/EU and the German Electrical and Electronic
Equipment Act („ElektroG - Elektro- und Elektronikgesetz“), we began marking our testers
in October 2005 with the following symbol
(
) (DIN EN 50419).
In other words, the ARGUS and its accessories may not be disposed of in the household
waste. Regarding the return of old equipment, please contact our Service department.

In some tests, a green circle with a green “S” will be shown in the
uppermost line in the display.
This indicates that the softkeys are assigned twice. In such a case, press
the Shift key to change the function of the softkey (for an example, see
Page 168).
Example
Pressing the Shift key will change
the softkey function.
The ARGUS is in largest part operated with the 4 cursor keys, the confirmation key
the return key
,
and the three softkeys.
The current assignment of the three softkeys is shown in the lower line of the display.

On the following pages, only the softkey's meaning in the respective context is shown enclosed in angle brackets < >, e.g. <No>. The softkey <
> serves the same function
as the confirmation key and the <> softkey performs the same function as the cursor key
on the ARGUS keypad.

Charging the accumulators for the first time
The compartment for the rechargeable battery pack (accumulators) is located on the back
of the case. Insert the battery pack with the locating lug at the top and then tighten the
thumbscrew. Use only the battery pack included in the package. With the ARGUS switched
off, connect it to the supplied plug-in power supply.
Press the

Power-Down Mode
Page 293 In battery mode, the ARGUS will automatically power down after it has
been idle for 15 minutes (this setting can be changed, see Page 293). 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 battery pack is automatically
disconnected. Regardless of the type of supply used, the battery pack should always
installed when you operate 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 (charging the battery pack).

6.3.1 Determining the ADSL connection parameter
The ARGUS is connected directly to the ADSL 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 an ADSL connection and determine all of the
relevant ADSL connection parameters. The ARGUS displays the ADSL connection
parameters and saves them after the connection is cleared down if desired.

8.3 Autonegotation / Ethernet Link Parameters
The Ethernet link "autonegotiation" is supported by the default setting.
When negotiating the link parameters, 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 parameters
When "autonegotiation“ is deactivated, the speed, duplex mode, flow control (flow control =
"Pause" mode) are set in the profile (see page 113). 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 (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.

10.1 IP Ping
In the IP ping test, the ARGUS checks whether it is possible to setup a connection to an
Internet Service Provider (ISP) via an Ethernet connection (IP network) or via an xDSL
connection (over a DSLAM and an ATM 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.

Fragmentation This parameter sets the fragmentation:
Default setting: on
on
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).

Profile name
Entry of a name for the profile
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.
However, 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 (taking into consideration the access speed). 

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 be the case e.g.

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 Profiles" can be configured for use in VoIP telephony.

The connection is cleared down in the same manner as it is after an IP ping.
However, pressing the "Cancel“ key once will only clear down the connection (if
there is one). The results will be saved when the key is pressed again. The
ARGUS however will remain registered with the Registrar so the ARGUS can still
be called (an incoming call can be rejected or accepted). If the "Cancel“ key is
pressed a second time, the registration is also terminated and you are given the
opportunity to save the results again. 
The Layer 1 connectivity originally setup for the VoIP connection remains.

The ARGUS requests a data stream from a server (Depending on the type of access, the
ARGUS will substitute for a settop-box (STB) or modem and STB) and checks the
regularity of the incoming packets, the loss of packets and the programme's switch on or
switchover time. Up to three user-defined "IPTV Profiles“ can be created (when the xDSL
connection has already been setup the access parameters, e.g. the ADSL mode and the

Mode
Manual: The address of the TV channel, whose data stream should
be analysed, must be entered under Multicast IP and Port. The time
span within which the ARGUS will attempt to receive a data stream is
unlimited. For an active analysis, the ARGUS must be set to
"manual“, it will then use the configured multicast IP address and
request the data stream.

Automatic: The ARGUS will search for the data stream with the
highest data rate of one of the TV channels available. You must enter
the time span within which the ARGUS will attempt to receive a data
stream under Scan time. The ARGUS operates in a passive yet
automatic mode, when the unit is in Bridge or router configuration.
Default setting: Automatic
Scan time

In this case, it is possible to use the IP header to enable the ARGUS
to determine the packet loss, if its ID field has been suitably
maintained.
Default setting: No
If Use IP Header has been set to “yes”, but the ID
field of the IP header has not been maintained, the

13.2 Initialization Phase Including B-Channel Test
Initialization on a S-Bus interface or U interface access
The ARGUS will begin the initialization after according the existing, confirmed settings or
new settings for the type of access and mode:
The ARGUS will first setup Layer 1. While Layer 1 is being setup, the "Sync / L1" LED
above 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 access, it can take up to 2.5
minutes to activate Layer 1. As soon as Layer 1 is successfully setup, “L1 Sync” LED will
light continuously. 

Once Layer 2 has been setup, the "Rx/Tx/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 (see page 202).
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 page 205. 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 Bchannel 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.

Alerting mode
You can specify whether, for an incoming call on a BRI point-topoint 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.
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

13.4 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 or
calls 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. Aself/ local test requires both
B channels since the bit error rate test checks the B-channels in both directions
simultaneously. 

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.

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.
ARGUS 142
209
13 Operation on an ISDN Access
3.
BERT end-to-end
This test requires a waiting remote tester (e.g., a second ARGUS in the "BERT wait"
mode). (see page 217 BERT wait) A bit pattern is sent to this remote tester.
Independent of the received bit pattern, the remote tester uses the same algorithm
to generate the bit-pattern that it sends back. Therefore, both directions are tested
independently.

Bit patt. BRI/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.
<Del.>
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" 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). 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.

Comments
TP
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.
No
Screening
If the caller supports „CLIP No Screening“, all of the net-side call
numbers connected with the ARGUS will be displayed.
The suppl. services pairs CLIP and CLIR as well as COLP and COLR will be
tested. 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 supplementary service MSN supported?
CF
The ARGUS will check whether the 3 suppl. services CFU, CFB and CFNR are
supported.
CFU:
ARGUS 142
Can this access immediately forward an incoming call?
221
13 Operation on an ISDN Access
CFB:
Can this access forward an incoming call when it is busy; in other
words does it support call forwarding busy?
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 295). The CF test
cannot be performed, if this location does not contain a valid call number to
which it is possible to divert a call.
CW
Does the access under test support call waiting?
CCBS / Will the access under test automatically recall a remote subscriber if the number
CCBS-T called was busy?
CCNR / Will the access under test automatically recall a remote subscriber if the call was
CCNR-T not answered?
MCID
Does the access tested allow identification of malicious callers (call tracing)?
3pty
Does the access under test support a three-party conference call?
For this test, you need the assistance of a remote subscriber, whose call
number must be entered.
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.
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 sub-address
in both directions.
Are sub-addresses supported on the access under test?
UUS
222
Does the access under test support the transfer of user data?

13.5.3 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" on page 303).

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.
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 *).

-
An outgoing call with this service is not possible
This is the error class D without allocation of a B-channel.
+*
The call was sent successfully, the call back or call to the remote end failed
(e.g., remote end busy or no B-channel available for the call back).
*
Wrong number, no B-channel available or other error
This is an error class B, C or D without allocation of a B-channel.

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.

13.7 X.31 tests
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 remote 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.

13.7.2 Automatic X.31-Test
D-Channel
The “X.31 Automatic, D-channel” test consists of two steps:
1. Step:
The ARGUS tests whether it is possible to access the X.25 service via the
D-channel on the S-Bus access under test. The ARGUS checks all of the
TEIs from 0 to 63 one after the other. All the TEIs, which support X.31service on Layer 2, will be displayed.
2. 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-dialing memory under X.31 test number (see page 295).
With the entry of the X.25 access number, you can - if you wish - select a
logical channel (LCN) other than the default.

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.

Advice of charges:
If the charges are not given in units, rather directly as currency, the ARGUS will display the
current charges in currency. If, in DSS1, the call charges are not provided in accordance
with the DIN ETS 300182 standard, rather in the form of the information element DISPLAY
(DSP), the ARGUS will display the DISPLAY message's character string.
Note regarding the entry of the call number
Separate the extension number 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 or 1TR6-OAD).
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).

13.12.1 Testing Features via the Keypad
This feature is only relevant on a S-Bus 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 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.

13.16 Leased Line 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 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
(page 205). 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 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
connection (see page 209, Parameter settings page 210), however, you need not enter call
numbers or select a service.

With this setting you can set the volume level used by the ARGUS to
signal an incoming call.
The initial volume level can be set.
- Default setting: Level 1 (very low)
In addition, you can also set the final volume level.
- Default setting: Level 7 (very loud)
When an incoming call is received, the ARGUS will begin signalling
with the initial (very low) volume and increase the volume by one
increment each time it signals until it has reached the final (very
loud) volume.
Alarm bell
The ARGUS signals with an audible alarm in a variety of situations,
e.g. when a bit error occurs in a BERT or the ARGUS has
synchronized on an xDSL or when an error counter increments. 
When this parameter is set to "off“, all audible alarms are
suppressed.
Default setting: Off

18 Saving Call Numbers in the Speed-dialing memory
Ten 24-place call numbers can be entered in the speed-dialing 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).
You can save remote call numbers in the memory locations “Remote No.1 – 8”. 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 227).

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 #) 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: 02351/9070-40 is entered as 023519070#40
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.

19 Using the Battery Pack
19 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 battery pack contacts 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.
-
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.
-
Please read the extensive notes on safety and the transport of the lithium-ion battery
pack found in the section "Safety Instructions“.
Automatic recharging of the battery pack when the ARGUS is switched off
The ARGUS automatically recharges the battery pack (often shortened to "accu" for
accumulator), 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. The ARGUS remains on after fully recharging the battery
pack.
296
ARGUS 142
19 Using the Battery Pack
Charge accus
The ARGUS will display the current charge of the battery pack 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 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.

20 Firmware Update
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 upgrade (USB cable with a miniUSB plug). 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.
