1 Introduction

The ARGUS 28 is a compact all-in-one tester, which can beexpanded in individual steps from a SHDSL tester all theway to a universal tester for E1, X.21, V.35, PRI, BRI and

POTS interfaces.

ARGUS 28 expansion levels:- Basic tester : SHDSL both remote and central ends,WINplus- Options :

- SHDSL 4-wire interface- POTS interface- Packet 1: PRI and BRI, WINanalyse- Packet 2: E1/PRI, extended BERT, BERT nx64 kBit/s,

MegaBERT, USB adapter- X.21 interface with X.21 cable- V.35 interface with V.35 cable- U-interface (4B3T)- U-interface (2B1Q)

The basic ARGUS 28 supports network operatorsparticularly in the installation and setup of the 2-wire SHDSLsystems. In this case, the ARGUS simulates both thenetwork and the customer side of the SHDSL connection.Even the customer's terminal equipment can be included inthe measurement process by simply connecting it to theoutput on the ARGUS 28, which then serves as a SHDSLmodem.With its rechargeable batteries and internal charger, theARGUS is exceptionally well suited for use in field service.The intuitive menu operation combines convenient cursorkeys and softkeys with a four-line backlit display.

Besides TE/NT simulation on BRI and PRI accesses, theARGUS 28 also supports TE simulation on U interfaces(optional) and POTS as well as convenient BRI and PRI D-channel monitoring. The 16 megabytes of internal Flashmemory enables the tester to record and save themonitoring data without requiring a connection to computer.

The Flash-ROM technology permits you to upgrade yourARGUS at any time by download software updates from aPC (free software updates are available at www.argus.info).

1 Introduction

8 ARGUS 28

If you use the ARGUS on a BRI or PRI interface in an ISDNsystem whose specifications deviate from the (DIN ETS 300102) standard (e.g. some networked PBXs), you must takethese manufacturer-specific modifications into account. Insuch cases, please contact the distributor of your ISDN PBXfor assistance.

To test X.21/V.35 permanent circuits, you can connect theARGUS to the X.21/V.35 network via the X.21/V.35 adapter.

As an option, a V5.x monitor is available for the ARGUS 28:This monitor can be used to record the V5.1 or V5.2protocol, which can then be decoded in detail with theWINanalyse software. The ARGUS Functions - Overview:

SHDSL test

Displays the SHDSL connection's most importantperformance parameters

Bit error tests (BERT) for SHDSL

Performs a BERT to a loopbox or in end-to-end operation.

The ARGUS will, if needed, handle the loopbox functionitself.

Listen/Talk mode (telephony) in TDM time slices

Tests a permanent circuit using a telephone connection to aremote end in a selected time slice.

Protocol Recognition and B-Channel Test for ISDN

Accesses

After you select the operation mode, the ARGUS willautomatically determine the protocol supported by theaccess under test and will then test the availability of the B-channels.

Telephone connections

Can a telephone call be placed from this access to everyother number and/or can this access receive a call?

1 Introduction

9ARGUS 28

Service Tests

Does the tested access support connections with the mostimportant services, such as, ISDN telephone service, Group4 - Facsimile or data transmission at 64 kbit/s etc.?Additionally, 3 user-specific services can be saved in the

ARGUS and tested on the access under test.

Bit error tests (BERT) for E1, PRI, BRI, U-interfaceaccesses

Performs a BERT in an extended call to itself via a loopboxor in end-to-end operation. The ARGUS will, if needed,handle the loopbox function itself.The integrated MegaBERT extends the bit error test on E1/ PRI accesses to a full 2 Mbit/s bandwidth. Any distribution

of time slots (n x 64 kBit/s ) may be used.Supplementary Services

The ARGUS automatically tests the supplementary servicesmade available by the exchange.

Leased Line Tests – tests permanent circuits with BERTand speech

NT simulation of a BRI or a PRI access

D-channel monitoring on a Basic Rate Interface and ona Primary Rate InterfaceAll of the D-channel signals are captured and passed to theserial interface. When passively monitoring, the ARGUSdoes not affect Layer 1.

POTS (analog) Functionality

Does the POTs access support call number transfer?The ARGUS will display the charges, if the access supportsthis feature.

Monitoring an analog line (passive listening-in)

CF Interrogation

The ARGUS will check, whether a call diversion has beensetup on the access under test. The ARGUS can setup orclear down call diversions in the exchange.

1 Introduction

10 ARGUS 28

MSN interrogation (only on a BRI access)

On a P-MP access using the DSS1 protocol, the ARGUSwill determine the MSNs of the access under test.

X.21/V.35 TestThe ARGUS will perform a bit error test on the X.21/V.35access in accordance with the ITU guidelines G.821 andG.826.

The Access Acceptance Report

When the ARGUS is linked to a PC via the serial interface, itis, as an example, possible - with the aid of WINplus - to

create and print a comprehensive test report on the PC. Testing Features with the Keypad

Supports manual tests in the so-called keypad mode. If thenetwork supports this feature, the user can send acommand sequence and can then test service features in adialog.

Replacing the accumulators

The battery compartment for the three accumulators(rechargeable batteries) is located on the back of the case.Unscrew the screws to remove the cover of the case andinsert the accumulators in accordance with the polarity

marking.

Use only NiMH accumulators.

The current state of the charge will (if the ARGUS is notconnected to a power supply) be displayed graphically.

In the LCD display, a battery symbol will begin to blink, whenthere is still approximately 5 minutes reserve. During thisperiod, it is possible that there may be audible interferenceand in rare cases even malfunctions (see “Accu servicing”on page 190.).

Power Down

In accu/battery operation, if the ARGUS is idle for 15minutes, it will automatically switch to the power-down mode(power-down).The ARGUS will remain in power-down mode until thePower-Key is pressed again.

Reasonably enough, the ARGUS willnot enter power-downmode during a test (e.g. Loopbox) or when it is in Tracemode.

As an alternative, it is possible to operate the ARGUS usingthe included power supply. If the ARGUS is connected tothe plug-in power supply, it will automatically disconnect theaccumulators and will - reasonably enough - not enterpower-down mode.

As soon as Layer 1 is successfully setup, LED L1 will lightcontinuously.

Once Layer 2 has been setup LED L2 will light.

If both modes (P-P / P-MP) are found when Layer2 on the D-channel is checked, the mode must beselected manually (see Page 35).

If everything has been correctly detected, the ARGUS willdisplay the access type and mode found. Additionally, aqualitative assessment of the level will be displayed.

The ARGUS will automatically determine the protocol (inboth TE and NT mode) or use the protocol selected in theConfiguration/ISDN menu (see on page 163 “Configuration:ISDN”) . On a bilingual access, the ARGUS will use theDSS1 protocol.

LED L3 will light after the ARGUS has setup Layer 3.At the same time the ARGUS will start the B-channel test.The results will be displayed on the ARGUS. If an erroroccurs in the B-channel test (e.g. access is not plugged-in),

the ARGUS will - depending on the class of error - eitherrepeat the initialization or show an error message ((seepage 202 ARGUS Error Messages)).

The ARGUS will then idle in the Status display.

The ARGUS displays thetype of access (BRI), theavailability of the B-channels(B12), a level evaluation(OK),the access mode (TEs), thebus configuration (P-MP)and the protocol (DSS1).Press the torepeat the B-channel test.

- Operation 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.CRC4 monitoring can be switched on or off manually ((see

page 167 CRC4 mode)).

The ARGUS will begin the automatic detection of the accessconfiguration. After Layer 2 is setup, the L2 LED will alsolight.The ARGUS will, regardless of the mode of operation (TE orNT mode), determine the D-channel protocol and attempt tosetup Layer 3.

During this phase, the

ARGUS displays the A bit ofthe remote side. Protocoldetection is only possiblewhen the A bit is not set (+).Afterwards, the B-channel

test will be started.

With the B-channel test, the ARGUS checks the availabilityof all 30 B-channels by placing an outgoing call on each B-channel one after the other. If the call can be setup, it isassumed that the B-channels are available from both ends.

If the connection is rejected with Cause 44 (see AppendixB), the B-channel will be assumed to be only available forincoming calls.

If the connection is rejected for any other cause, the B-channel will be identified as unavailable. In the case of acause, which indicates that the B-channel is occupied, theconnection will be tried up to two times and, if a connectioncan still not be setup, it will then be marked as unavailable.

Besides dial-up connections to any subscriber, ISDN alsosupports the use of permanent circuits switched to a specificremote location.

These permanent circuits are available after setting upLayer 1, in other words after synchronizing both terminals byexchanging HDLC-frames.

The location where the clock is generated can be selected(see page 165 Clock mode).

As a quick test of a permanent circuit, you can simply callthe 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 samechannel.

BERT on permanent circuits

A number of variations are possible in testing the permanentcircuit with the bit error rate test.

In the simplest case, a B-channel loop will be set up at theremote end.Start the BERT from theSingle tests menu / Bit error testsubmenu / BERT start (see page 94 Start BERT). Afterselection of the channel to be tested (B-channel or D-channel), the ARGUS will send the test pattern, receive itback and evaluate it accordingly.

The displays and operation are, in largest part, similar tothose of a BERT on a dial-up connection (see page 92 Biterror test), you simply need not enter call numbers or selecta service.

In the case of a BRI access in end-to-end mode (on page 92“Bit error test”and on page 100 “BERT wait”), it is alsopossible to run a BERT in the D-channel.

channels, the ARGUS will send the test pattern (see page172 Bit pattern BRI/U) selected, receive it again andevaluate it in accordance with the ITU guidelines G.821 andG.826 (loopbox required at the remote end).

Press to start theBERT

Displays the bit pattern(2^15), the X.21/V.35 datarate (1984 kBit ), theremaining test duration inh:min:sec (15:45:42), thenumber of bit errors that haveoccurred (3), thesynchronicity of the bit pattern(synchron) and the LOS-counter.

Press to restart thebit error test; the counters(e.g. number of bit errors) willbe reset.Press to inject an“artificially generated” biterror, which can demonstratethe reliability of themeasurements in particularwhen running end-to-endtests.

When a bit error is detected, this will be signaledby a brief alarm (if the alarm is enabled); in theevent that the synchronisation is lost, a constantalarm will sound.The alarm bells can be switched off.(see page 184 Alarm bell).

The measurement time for the BERT can be set with theBERT config. function (see page 171 BERT - duration).

10.3 Bit error test

The bit error rate test (BERT = Bit Error Rate Test) servesto check the transmission quality of the access circuit.In the bit error test, the ARGUS sets up a SHDSL

connection to a remote tester or places a call to itself, sendsa standardized (quasi-) random number string andcompares the received data with that which was sent.During the test, the ARGUS counts the bit errors and afterthe test is done it calculates the bit error rate and otherparameters in accordance with the ITU guidelines G.821and G.826.Normally, the bit error rate during a 1 minute test should beless than 10-7.

However, if the test shows a higher bit error rate, it shouldbe repeated with a measurement time of 15 minutes toincrease its statistical precision.

The BERT can be performed in different ways:

BERT with a loopbox

A loopbox (e.g., another member of the ARGUS familyof testers at the remote end) is required.

BERT end-to-end

This test requires a waiting remote tester such as anARGUS in theBERT wait mode . A bit pattern is sent tothis tester.

Independent of the received bit pattern, the remotetester uses the same algorithm to generate a bit-patternthat it sends back.

Therefore, both directions are tested independently.

The ARGUS will display theresults of the test once it isdone.Use the < ↓ > to scrollthrough the test results.The ARGUS makes adistinction between outgoingcalls (the first +, - or *) andincoming calls (the second+, - or *).+ = Service supported- = Service not supported* A definite statement cannotbe given due to the adjacenterror code.

Interpreting the testresults:

Displayed Description

+ + The self call functions OK or the remote end cantake the call for this service

+ - Call was sent successfully, however, it was rejectedon the remote end due to missing authorization.(Error class D in a B-channel message e.g. in aSETUP_ACK or CALL_SENT)

- An outgoing call with this service is not possible(Error class D without a B-channel message)

+ * Call was sent successfully, the call back or call tothe remote end failed (e.g., remote end busy or noB-channel available for the call back).(Error class B, C or E in a B-channel

message)* Wrong number, no B-channel available or other

error(Error class B, C or E without a B-channel message)

If the outgoing call is not successful, it isnot possible tomake a statement about an incoming call. Therefore, youwill never see “- +” or “- *” on the display.
