ARGUS 25
1 Introduction
1 Introduction
ARGUS tests the operation of
an ISDN Basic Rate Interface (BR)I
a Primary Rate Interface (PRI)
U-interface and
an analog access.
The ARGUS Flash-ROM technology permits the user to
download future protocol changes or new functions from a
PC into the ARGUS.
If you use the ARGUS on a BRI or PRI interface in an ISDN
system whose specifications deviate from the (DIN ETS 300
102) standard (e.g. some networked PBXs), you must take
these manufacturer-specific modifications into account. In
such cases, please contact the distributor of your ISDN PBX
for assistance.
The ARGUS Functions - Overview:
•
Protocol Recognition and B-Channel Test
After you select the operation mode, the ARGUS will
automatically determine the protocol used by the access
under test and will then test the availability of the Bchannels.
•
Telephone connections
Can a telephone call be placed from this access to every
other number and/or can this access receive a call?
•
Service tests
Does the tested access support connections with the most
important services, such as, ISDN telephone service, Group
4 - Facsimile or data transmission at 64 kbit/s etc.?
•
Bit error tests (BERT)
Performs a BERT in an extended call to itself via a loopbox
or in end-to-end operation. The ARGUS will, if needed,
handle the loopbox function itself.
•
Supplementary Services
ARGUS 25
7
1 Introduction
ARGUS automatically tests the supplementary services
made available by the exchange.
• Tests leased lines (permanent circuits) with BERT
and speech
•
NT simulation of a BRI- or a PRI access
•
D-channel monitoring on the Basic- and PrimaryRate Interfaces
All of the D-channel signals are captured and passed to the
serial or infrared interface.
When passively monitoring, the ARGUS does not affect the
Layer 1.
•
Analog (a/b) Functionality
Does the analog access support call number transfer?
The ARGUS will display the charges, if the access supports
this feature.
•
Monitoring an analog line (passive listening-in)
•
Line tests
Checks the terminating resistors for the cabling of a fourwire bus.
Detects cabling problems (e.g. broken wires, short-circuits
or crossed wires).
•
The Access Acceptance Report
When the ARGUS is linked to a PC via the serial or infrared
interface, it is, as an example, possible to create and print a
comprehensive test report on the PC.
•
Testing Features with the Keypad
Manual test possibilities in the so-called keypad mode. If the
network supports this feature, the user can send a
command sequence and can then test the service features
in a dialog.

Infrared Interface
The wireless transfer of data to a PC is possible using the
integrated infrared interface.
The infrared interface must be in the line of sight of the
receiver. During data transfers, the IR beam can be
interrupted for up to 30 sec without disturbing the transfer.
During the interruption, the data will be buffered and will
therefore not be lost.
During the recognition phase, the ARGUS must be within 20
cm of the PC’s infrared receiver. Later, during the data
transfer, the IR-link will work at distances of – depending on
the baud rate – up to 70 cm.
Changing the batteries
The battery compartment for three AA (Mignon) batteries or
accumulators is located on the back of the case. Unscrew
the screws to remove the cover of the case and insert the
batteries in accordance with the polarity marking.
A battery symbol begins to blink in the LCD display, when
there is still approximately 15 minutes reserve. During this
period, it is possible that there may be audible interference
and in rare cases even malfunctions.
Power Down
In battery operation, if the ARGUS is idle for 15 minutes, it
will automatically switch to the power-down mode (powerdown). From this mode, the system can only be reactivated
by pressing the Power-Key. In the power-down mode, a
battery will last about 3.8 years. Therefore, this mode serves
as an effective protection against discharging the batteries.
ARGUS 25
15
4 Operation
Naturally, when the loopback function is active on the
ARGUS or it is in Trace mode, the ARGUS will not switch to
power-down mode.
As an alternative, it is possible to operate the ARGUS using
the included power supply. When the power supply is
connected, the battery is automatically disconnected.
The ARGUS can also be powered from the BRI line. In this
case, it does not need batteries, accumulators, or the plug-in
power supply.
Whenever the ARGUS is powered from the plug-in power
supply or the BRI line, the power-down mode is reasonably
enough not active.
Regardless of the type of supply used, you
should always operate the ARGUS with
batteries installed. This will ensure the
uninterrupted operation of the real-time clock.

U-Interface accesses to TE-mode(see section 6.4.1 page
38).
In this case, the Access Mode menu will not open,
therefore functions such as S0-Monitor, S0Recorder and Permanent Circuit are not available.
The selected type of access will be marked on the left edge

being setup, the L1 LED above the display will blink. If an
error occurs, the message no Net will be displayed.
As soon as Layer 1 is successfully setup, LED L1 will light
continuously.
When the ARGUS is operated on a U interface, it can take
up to 2.5 minutes to activate Layer 1.
As soon as (and as long as) Layer 2 is successfully setup,
LED 2 will also light.
If no error occurs, the ARGUS will display the successfully
found access and access mode in the third line.
Additionally, a qualitative assessment of the level will be
displayed.
The ARGUS will, regardless of whether it is in TE or NT
mode, automatically determine the protocol and attempt to
setup Layer 3 (LED L3 lights). At the same time, the Bchannel test will be started and the results will be displayed.
The ARGUS will then idle in the Main menu’s status display.

The ARGUS is in TE Slave Mode.
On a bilingual access, the ARGUS uses the DSS1 protocol
and thus behaves as a "DSS1 terminal".
You can manually switch the ARGUS to the 1TR6 protocol
using the Protocol function in the Configuration/ISDN menu
(see “Select the D-channel protocol” on page 128).

- Using an ARGUS on a PRI Access
As soon as Layer 1 is setup, LED L1 will light continuously.
The ARGUS will automatically determine and display,
whether or not the PRI access uses CRC4-monitoring.
The ARGUS will begin the automatic detection of the access
configuration. After Layer 2 is setup, the L2 LED will also
light.
The ARGUS will, regardless of the mode of operation (TE or
NT mode), determine the D-channel protocol and attempt to
setup Layer 3. At the same time, the B-channel test will also
be started.
With the B-channel test, the ARGUS checks the availability
of all 30 B-channels by placing an outgoing call on each Bchannel one after the other. If the call can be setup, it is
assumed that the B-channels are available from both ends.
If the connection is rejected with Cause 44 (see Appendix
B), the B-channel will be assumed to be only available for
incoming calls.
If the connection is rejected for any other cause, the Bchannel will be identified as unavailable. In the case of a
cause, which indicates that the B-channel is occupied, the
connection will be tried up to two times and, if a connection
can still not be setup, it will then be marked as unavailable.

6.2 Status display
The ARGUS automatically determines the configuration of
the access and the protocol used and inserts both
parameters in the remaining tests. Thus manual
configuration of the ARGUS is unnecessary. However, it is
possible to manually change the protocol using the
Configuration menu (see section 6.9.2.2 Select the Dchannel protocol page 128).
The status of the access under test (PRI, U interface, BRI or
analog) is always displayed in the first line.
It must be mentioned again, that the ARGUS only
determines the general bus status once – automatically
when switched on or when the ARGUS first connected.
On the other hand, the status of the protocol stacks for
Layer 1, 2 and 3 will be continually monitored and displayed.
To repeat the B-channel test, press the <RESTART> softkey
on the right.
If the test cannot be executed without errors (e.g. because
the access was unplugged), the ARGUS will, depending on
the class of error (see “Suppl. Services Tests – Error
messages” on page 91), reinitialize or show an error
message.

In the Access menu, the user must select the type of
physical access to which the ARGUS is connected. When
the ARGUS is restarted, the settings used last will be
suggested as the default.
If Automatic is selected, a fully-automatic process will be
started: The ARGUS will automatically recognize a BRI,
PRI, Uinterface or analog access. In the case of a BRI or U
interface access, the ARGUS will be set in the TE mode and
the access mode (PP or P-MP) will be determined
automatically. When the ARGUS finds a PRI access, it will
enter the TE mode PP.
The ARGUS will determine which D-channel protocol is
used on the BRI, PRI or U interface access and perform the
B-channel test. After the level was measured (only for an

6.4.2 Line test
The ARGUS tests the terminating resistors for the cabling of
a four-wire bus. Additionally, the test also detects errors in
the cabling e.g. any broken wires, short-circuits and crossed
wires.
Unplug the NT and all terminal equipment from
the bus, before performing a line test!
If the ARGUS detects an operator error (Line test on a fed
bus), it will emit a continuous acoustic signal. In this case, to
prevent the destruction of the ARGUS, the line test will not
be started.
Test sequence:
To perform a thorough test of the lines, the test must be
done in 2 steps.
First step:
Use the test adapter to connect the ARGUS to the lines to
be tested. In this step, the ARGUS will determine whether or
not there is a short circuit or a terminating resistor and
whether there is a fault between the terminating resistor – if
there is one – and the test adapter.

6.5.1.3 Permanent switch
Besides dial-up connections to any subscriber, ISDN also
supports the use of permanent circuits switched to a specific
remote location.
These 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
on the ARGUS(see section 6.9.2.4 Clock mode page 130).
As a quick test of a permanent circuit, you can simply call
the opposite end using a selected B-channel. However, for a
more revealing test of a permanent circuit, you should
perform a bit error rate test.
Both ends of the permanent circuit must use the same
channel.
Telephony on permanent switches
The function can be started with the
-Key or via the
selection phone / connec. in the Single tests menu (see
section 6.6.1 page 63).

pattern, receive it back and evaluate it accordingly.
The display during and after the bit error rate test as well as
the operation are in largest part similar to that of a BERT
with dial-up connections (see section 6.6.6 Bit error test
page 95). The only difference is that it is not necessary to
select a call number or service.
In the case of a BRI0- or a PRI access in end-to-end mode
(see “Bit error test” on page 95 and on page 102 “Bert wait”),
it is also possible to run a BERT in the D-channel.

6.5.1.5 BRI/PRI Recorder
In the Recorder mode, the ARGUS passively monitors the
connected BRI or PRI access.
The ARGUS records all of the D-channel signals sent in
both directions without affecting the access or Layer 1.
Unlike in the Monitor mode, the recorded D-channel signals
ARGUS 25

will be saved in the ARGUS’s internal FLASH memory and
not sent to a PC.
The storage is organized as a ring buffer, i.e. as soon as the

write the oldest data.

The extension is separated from the access number
by a #. 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).
An example:
02351 / 9070-20 is entered as 023519070#20.
Call numbers can be deleted digit for digit with the < DEL>Key (DELete).

6.6.3.2 B-channel delay
The ARGUS places a call to itself (self call) or to a remote
loopbox and measures the propagation delay for the data in
the selected B-channel. The propagation delay is given in
multiples of the time required for sending one byte at 64
kBit/s. (The time for sending 1 byte at 64 kBit/s = approx.
125 µs.)
After the B-channel delay function is started, you must enter
the call number, the service and the B-channel (see “Setting
up an ISDN connection” on page 63). The ARGUS
disconnects automatically as soon as the measurement is
completed.

propagation delays (interchannel delay).
The difference in the propagation delay (interchannel delay)

There are PBXs that use separate call numbers for
incoming and outgoing calls.
In this case, for the Service checks, you can enter a
“remote” call number that corresponds to the “own”
number that is not 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.

6.6.6 Bit error 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 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 Guidelines G.821 and G.826.
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.
Since the bit error test checks both B-channels in both
directions at the same time, both B-channels are required.
The duration of the BERT can be set in the Configuration/
BERT (see “BERT - duration” on page 141) menu (default
setting = 1 minute).
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. If more than 10 bit errors occur during
this 15-minute test (call to oneself), the access circuit is too
heavily distorted.
Contact the network operator or the supplier of the PBX
equipment and ask them to test your access circuit.
ARGUS 25
95
6 Menus
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 ISDN
connection is setup 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 section 6.6.6.2
page 102). A bit pattern is sent to this tester.
Independent of the received bit pattern, the remote
tester uses the same algorithm to generate the bitpattern that it sends back.
Therefore, both directions are tested independently.

6.6.6.2 Bert wait
For this operation mode, it is necessary to use the BERT
start function in an end-to-end test.
The ARGUS first waits for a call and then sets up the
connection.
During the connection, the received bit pattern will be
evaluated and an additional independent bit pattern will be
sent.

6.6.7 X.31 Test (only on a BRI access)
The X.31 test 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 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 shown on
the display.
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 (“Saving Call Numbers” on page 165).
With the entry of the X.25 access number, you
can - if you wish - select a logical channel (LCN)
other than the default. For this purpose, append
a “#” plus desired the LCN to the access number
(default: LCN = 1).

Some PBXs or exchanges do not permit the use of
the mechanism used (by the ARGUS) for the CF
test for all MSNs or they return a negative
acknowledgment of the CF interrogation, implying
that no CF was setup.
Therefore, in the event of a negative
acknowledgment, the ARGUS will request that you
enter your own MSN.
The CF interrogation will be repeated MSNspecific.
Naturally, in this case, the results of the CF test only
apply for the entered MSN and not for the entire

Accepting an incoming call/connection
during a running test
The ARGUS signals an incoming call with a corresponding
message on the display and an audible signal (see section
6.6.1.1 Setting up an ISDN connection page 63).
The incoming call can be accepted without influencing the
currently running test. If the functions B-channel loop or
BERT wait are active, the call will be accepted
automatically.
The manner that multiple connections are handled is
illustrated in the following example of an incoming call that
arrives during a BERT, but it is identical for all other tests.

The Trace mode setting is only saved temporarily.
In other words, Trace mode is always off when the
ARGUS is first switched on.
With the setting Trace mode “On, PC”, the ARGUS remains
active, and sends all of its own D-channel messages and
those that it receives from the network to the PC.
When the trace mode is active, the LED labeled “Trace” will
be on continuously. If the ARGUS cannot send the data to
the PC without errors, the LED will flash at 5Hz (5 times per

In the Trace mode “On, Recording”, the ARGUS remains
active, but saves the D-channel messages in the internal
Flash memory. This trace mode setting is indicated by a
slowly flashing the LED (once per sec).

6.9.2.3 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 you select Manual, the extension can be displayed (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 not that the remote
subscriber will not hear a ringing tone.
If you select 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.

You can either specify that the ARGUS generates the clock
(is Master) or that it is the slave of a clock generated at the
other end.
In NT-Simulation, the ARGUS is by default Master. For a

The default threshold (error 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 test will be
evaluated as OK.
If the bit error rate is greater than the error level value, the
ARGUS will display NO. This parameter can be set to any
value from 01 (= 10-01) to 99 (= 10-99).

When entering a 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.
An example:
02351/9970-45 is entered as 023519970#45
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.

ARGUS 25
6 Menus
The meaning of the individual displays:
Signal:
correct
On its receiving-side, the ARGUS has the
signal sent from the remote end (access
or
terminal depending on the operation mode TE
or NT simulation) and indicates this by a +. If Rx
and Tx are connected normally a "=" will be
shown after the signal; in the event that they are
inverted a "X" will be displayed.
FAS:
(= Frame Alignment Signal)
Indicates whether the ARGUS could correctly
synchronize with the incoming 2 Mbit data
stream’s alternating frame identification word or
message word and the, perhaps present,
CRC4-superframe structure.
CRC det:
If CRC4-monitoring is active for the access or
the terminal
and the ARGUS is able to synchronize itself to
the CRC4 superframe, it will indicate this by
displaying ”CRC det +”.
If ”CRC det –” is displayed together with ”Signal
+” and ”FAS +”, this indicates that no CRC4 is
active.
In the example,”CRC det + !” indicates that
CRC4-monitoring is active, but that CRC4 errors
were detected within the last 1:23 minutes
(normally this is just the effect of switch on
transients). Nonetheless, we recommend that
you press DEL to reset the display and counter
to their defined initial states so that you can see
whether further errors occur that would indicate
problems on Layer 1.
Code HDB3: Displays the transmission code used
(currently fixed to HDB3)
noA-Bit:
With the A-Bit, the remote end can indicate
whether the route on its receive-side is no
longer
available
noA-Bit + means A=0: Idle state
noA-Bit - means A=1: Return direction is not
available
noAIS:
(Alarm Indication Signal)
AIS will be set if a component on the
ARGUS 25
177
6 Menus
transmission line determines that the signal they
have received is faulty (e.g., in the event, that
they lose frame synchronization) and afterwards
they will send a Time –1 (=AIS).
noAIS = + : No AIS occurred.
E-Bit:
With the two E-Bits, E1 and E2, the remote end
will report any CRC4-errors that it finds on its
receive side in the first or second submultiframe
(the E-Bit will be set to 0)
E-Bit11+ : if both E-Bits are set to 1, no error
occurred
E-Bit11+! : A CRC4-error was found (indicated
by the “!”), however the circuit is in largest part
OK (see the E-Bit counter Ecnt and/or the
CRC4 error counter CRCErr).
Ecnt:
The E-Bit counter counts the reported E-Bit
errors individually; in other word, all the cases in
which a faulty CRC4 submultiframe was
received (counts at a maximum of 1kHz).
CRC Err:
The CRC4 error counter totals the number of
CRC4 submultiframes in which errors were
detected...
CRC rel:
Gives the CRC4 error rate, in other words, the
number of faulty CRC4 frames relative to the
total number of CRC4 frames received.
Code Err: Counter for the detected HDB3 transmission
code errors
Code rel:
Transmission code - error rate
Frame Err: Counter for faulty 2Mbit frames

6.12 Testing Features with the Keypad
This feature is only relevant for a BRI 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.
An outgoing call containing a keypad message is placed
from the ARGUS by pressing the
-Key.
To distinguish the call from a normal call, the first character
sent is the '#'. Each step is acknowledged either acoustically
(handset) or via special protocol elements (cause). These
causes are displayed by the ARGUS.
To simplify the use of these functions, you can use the
ARGUS’s speed-dialing memory.

Since there is no commonly accepted standard for the

different forms of connectors depending on the type of
terminal and the network termination used.
The ARGUS changes the connector pin assignments
automatically in accordance with the mode, TE or NT.
Additionally, it is also possible to change the pin
assignments manually in the L1-Status menu.
7.1 Connector Pin Assignments
In TE mode, the ARGUS sends on lines 1 and 2, in NTMode on 4 and 5 (see illustration). An adapter cable, which
is suitable for the respective ISDN network/system, can be
