1 Introduction 1 Introduction The ARGUS 3u installation tester makes installation work and trouble shooting on BRI and POTS accesses both safe and uncomplicated. Additionally, the ARGUS 3u also supports U-interface accesses. With its rechargeable batteries and internal charger, the ARGUS 3u is exceptionally well suited for use in the field. The intuitive menu operation combines convenient cursor keys and softkeys with a four-line backlit display.
1 Introduction Service Tests Does the tested access support connections with the most important services, such as, ISDN telephone service, Group 4 - Facsimile or datatransmission 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) 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.
1 Introduction Access Acceptance Reports (with optional WINplus) When the ARGUS is linked to a PC via the serial interface, it is, as an example, possible 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 the network supports this feature, the user can send a command sequence and can then test service features in a dialog.

6 Automatic Access Test 6 Automatic Access Test Using the included cable, connect the ARGUS to the access to be tested. Power Key: Switch on the ARGUS. The ARGUS automatically performs an access test (Automatic setting in the Access menu see Page 26). No manual entries are required. The The access under test (BRI, U interface or POTS) can also be connected afterwards. If the ARGUS finds a DC voltage on the 2-wire line (UInterface or POTs), it will check whether there is a HF signal on the line.
6 Automatic Access Test 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 31). If everything has been correctly detected, 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 automatically determine the protocol or use the manually selected protocol (see Page 116) .

7 Setting the type of access 7 Setting the type of access In the Access menu, the user must select the type of physical access to which the ARGUS is actually connected. If Automatic is selected, a fully-automatic sequence will be started: The ARGUS will automatically determine the type of interface (BRI, U interface or POTS) and set the access to TE-mode. Status display If you press the softkey, the B-channel test will be repeated.
7 Setting the type of access 7.1 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.
7 Setting the type of access Possible test results: - The ARGUS has detected a short-circuit: Clear the fault and repeat the test - The ARGUS reports that the resistance is wrong: Repeat the test from another socket, if necessary remove the terminating resistor(s) - The ARGUS reports that the line is OK: Continue test with step 2 Second step: Connect the test adapter to the jack, which was tested as OK in the first step. Connect the ARGUS via its L-Test jack to the next socket on the bus.
7 Setting the type of access Test steps on the ARGUS: With the <↓>, select Line Test. Start the Line Test Sample test results – Line Test: No errors occurred. Wires 3 and 6 are crossed. If the message “Crossed wires: Term. wrong”, the measurement conditions with respect to the location or complexity of the fault are unfavorable. In this case, you should change the measurement conditions in the following manner: Remove the terminating resistors from the bus and repeat the test.
7 Setting the type of access - 30 The displayed test results are either for just the bus lines between the ARGUS and the test adapter in the case of cross-wires and broken connections or for the entire bus in the event of short-circuits and terminations.
8 Select the Access Mode 8 Select the Access Mode The Access Mode menu is not selectable from the Main menu. It opens automatically once the physical access is selected in the Access menu. 8.1 Operation on a BRI or U-Interface access 8.1.1 TE-Simulation mode TE automatic On a BRI or U-interface access, the ARGUS will automatically determined the D-channel Layer 2 mode (PP or P-MP).
8 Select the Access Mode 8.1.2 Permanent circuit With the <↓ >, select Permanent switch. Access mode confirmed The ARGUS is now switched to Permanent circuit mode (the display shows LL [Leased Line]) and will open the Status display. 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.
8 Select the Access Mode Telephony on permanent circuits The function can be started with the -Key or via the Phone / connec. function in the Single tests menu (see Chap. 10 page 83). After the B-channel for the permanent circuit is selected, the telephone connection will be setup automatically. The ARGUS displays the Bchannel used (e.g. B01) and the duration of the permanent circuit.

8 Select the Access Mode 8.1.3 BRI Passive Trace/Monitor (optional) In the Pass.trace mode, the ARGUS passively monitors the connected BRI access (signals from the remote end and the signals it sent to the NT itself) . The ARGUS sends the captured D-channel signals via the serial interface to the connected PC, which must be running either ARGUS WINplus or ARGUS WINAnalyse. Neither the S-Bus nor Layer 1 are influenced. In Monitor mode, the ARGUS also monitors signals sent from other TEs to the NT.
8 Select the Access Mode Parallel call display in the BRI pass. trace mode While in trace mode, the ARGUS will search all of the D-channels signals sent for a SETUP. If a SETUP is detected, the softkey will be displayed. Display the call parameters of the last SETUP received. The ARGUS displays the call direction (Net -> User), the service (e.g. FaxG3), the own number (e.g. 125670), the channel used (e.g. B01) and the destination number (e.g. 02351 901729).
8 Select the Access Mode 8.1.4 Recorder In the Recorder mode, the ARGUS passively monitors the connected BRI access. The ARGUS records all D-channel signals from the remote end and the signals that it sent to the NT itself, without influencing the access or Layer 1. Unlike in the BRI pass. trace mode, the recorded D-channel signals 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.
8 Select the Access Mode Parallel call display while recording The ARGUS searches all of the D-channel signals sent for a SETUP. If a SETUP is detected, the softkey will be displayed. Use to display the call parameters of the last SETUP received (see page 39).
8 Select the Access Mode 8.1.4.1 Administration of the recorded data In the Recorder mode, several functions are available for administration of the data saved in the Flash memory: - PC load all - Info Flash - Reset Flash PC load all With the PC load all function, the ARGUS will download all of the contents of the Flash memory via the serial interface to the PC, which must be running either WINplus or WINanalyse. The ARGUS is in "Recorder" mode (Recording not active) Using < ↓ >, select PC load all.

9 Single Tests 9.1.2 Suppl.service interrogation in DSS1 In the Single tests menu, using the < ↓ >, select Supp.serv.test. Use the keypad to enter the "Own number" or select if from the speed-dialing memory (the number of the access under test) (see “Saving Call Numbers” on page 129.). The ARGUS will test the availability of the supplementary service (in part by placing a call to itself). Using the < ↓ > , select the service which should be used for the supplementary services test. Confirm the service.
9 Single Tests previous display (this applies for all displays). Test 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 In this test, the ARGUS checks 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.
9 Single Tests CF (CFU, CFB, CFNR) In this test, the ARGUS checks whether the 3 supplementary services CFU, CFB and CFNR are supported.
9 Single Tests 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.
9 Single Tests 9.1.3 Suppl. Services Tests – 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). Use < ↓ > to scroll through. In the example, the error belongs to the error class "wrong or invalid number".
9 Single Tests 9.2 Service check The ARGUS checks, which of the following services are supported by the access under test: Service Name in the ARGUS display abbreviation Language Language / Lang Unrestricted Digital Information UDI 64kBit / UDI 64 3.1 kHz Audio Tel.analog / Tel. 7 kHz Audio 7 kHz audio / 7 kHz Unrestricted Digital Information with tones / Display UDI+TA / UDI TA Telephony Tel.ISDN / Tel.
9 Single Tests so no charges will be incurred. In the Single tests menu, < use ↓ to select > Service test. Enter the Own number of the access under test 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.
9 Single Tests The ARGUS will display the results of the test once it is done. Use the < ↓ > to scroll through the test results. The ARGUS makes a distinction between outgoing calls (the first +, - or *) and incoming calls (the second +, - or *). + = Service supported - = Service not supported Test results: * A definite statement cannot be given due to the adjacent error code.
9 Single Tests Example: For outgoing, the Fax G4 service is OK. No statement is possible about incoming. The error code 63 indicates the cause of the error which has occurred (see tables in appendix). In this case, it is recommended that you have someone place a call to the access under test using this service. The Mixed Mode service is possible in both directions. If an error of error class A occurs (see “Suppl. Services Tests – Error messages” on page 53.) the Service test will be aborted.
9 Single Tests 9.3 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.
9 Single Tests 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 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.
9 Single Tests 9.3.1 Start BERT The following parameters are required for the BERT: - Duration of the BERT (default setting = 1 minute) - Error level: If the bit error rate exceeds this limit, the ARGUS will display the test result NO. If the bit error rate is less than this limit, the ARGUS will display an OK - (default setting = 10-05) HRX value in % (hypothetical reference connection see ITU-T G.
9 Single Tests After the ARGUS has setup the connection and synchronized the send and receive directions, it will display the bit pattern, the Bchannel used (e.g. B02), the remaining test time in h:min:sec, the number of bit errors that have occurred (e.g. 3), the synchronicity of the bit pattern (synchronous or asynchronous) and the LOS-counter (e.g. 5).
9 Single Tests After the test time is over, the ARGUS will display the cause and the location which initiated the disconnect. If the test ran normally, the ARGUS will display “Active clearing” on this line. The test results display: The bit pattern (e.g. 2^15), B-channel used (e.g. 02), Transferred data in KBit (e.g. 10309 KB, K= 1024* bits), The number of bit errors (e.g.10), The bit error rate (e.g. 9.7E07 = 9.7·10-7 = 0.00000097), The evaluation of the results depends on the error threshold (OK).
9 Single Tests SES821 Severely Errored Seconds The number of seconds in which the bit error rate is >10-3. In one second, 64,000 bits are transferred, thus BitERror=10-3 equates to 64 bit errors. US Unavailable Seconds The number of sequentially adjacent seconds (at least 9 sec) in which BER>10-3. AS Available Seconds The number of sequentially adjacent seconds (at least 9 sec) in which BER<10-3. DM Degraded Minutes The number of minutes in which the bit error rate is >10-6.
9 Single Tests 9.3.1.1 BERT - saving The ARGUS can store the results of several BERTs. The ARGUS saves the results together with the date, time (if the network supplies the date and time) and the call number of the access under test (if this number has been entered as the "own" number in the speed-dialing memory) under the next free record number (see “Automatic Test” on page 99.). If all of the records are used, the ARGUS will return to the Autom.

Use the < ↓ > to select Bchannel loop . Activate the "B-channel LOOP“ Operating mode B-channel The ARGUS will wait for a call. Any incoming call (regardless of the service) will be taken immediately.
9 Single Tests 9.4 X.31 Test The ARGUS will either perform a “Manual X.31 Test” or an “Automatic X.31 Test”: In the case of an automatic test, the ARGUS will first setup the D-channel connection and then begin setting up the 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 Dchannel connection and an X.31 connection. The duration of this connection is determined by the user (or the opposing end).
9 Single Tests In the Single tests menu, use < ↓ > to select the X.31 test. Use < ↓ > to select Automatically. Start test The test can take up to 4 minutes (a rotating bar will be displayed). Beginning on the left, the ARGUS will display the TEI currently being tested followed by the one previously tested and its result: + = X.31 is available for this TEI - = X.31 is not available for this TEI Once the test has ended, the ARGUS will show whether the X.
9 Single Tests 9.4.2 Manual X.31 Test In this test variant, the ARGUS first requests a TEI, LCN and an X.31 number (The ARGUS uses the TEI and LCN values stored in the Configuration/X.31 as default values - seePage 125) and the call number saved as the X.31 number in the speed-dialing memory (see Page 129). If a “ ** ” is entered for the TEI, the ARGUS will automatically determine a TEI. Using the first TEI with which X.31 is possible, the ARGUS will begin to setup a connection.
9 Single Tests -Key The ARGUS will count the data packets sent and received and will display (where possible) the contents of the data packets received. The ARGUS will display the number of packets sent (e.g. 3), the number of packets received (15) and their contents (in ASCII). The contents of the received data packet (in hexadecimal) The connection will be maintained until the user or the opposing end clears it. When the X.
9 Single Tests 9.5 CF Interrogation The ARGUS will check whether a call diversion has been setup in the exchange for the access under test (BRI or UInterface). The type of diversion (CFU, CFNR or CFB ) and the call diversion's service will be shown in the display. The display is limited to a maximum of 10 call diversions for all of the MSNs. The ARGUS will count any additionally setup call diversions. The ARGUS can clear any call diversion setup in the exchange.
9 Single Tests 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 setup. 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.
9 Single Tests 9.6 CF - Activation Using the ARGUS, call diversions can be setup in the exchange (BRI or U-Interface). In the Single tests menu, use > to select CF the <↓ activation.

Press to delete the digit before the cursor. Enter the number to which calls should be diverted.
9 Single Tests 9.7 CF - Delete Using the ARGUS, selected call diversions can be deleted/ cleared in the exchange (BRI or U-Interface). In the Single tests menu, use the <↓ > to select CF delete. Using the < ↓ >, select the service of the call diversion (e.g. SPch). Using the < ↓ > select the type of call diversion (e.g. CFU). Under "Own number", enter the number which should no longer be diverted. Press to delete the digit before the cursor.
9 Single Tests 9.8 MSN Interrogation (only on a BRI with DSS1) On a P-MP access using the DSS1 protocol, the ARGUS will determine the MSNs of the access under test. It will display a maximum of 10 call numbers.
9 Single Tests 9.9 Time measuring The ARGUS measures three different times: - Connection setup time Propagation time of the data and Transit time differential (interchannel delay) of the data in two B-channels. Time measurements on a BRI or U-Interface access are only possible in TE mode.
9 Single Tests 9.9.1 Connection setup time The ARGUS places an outgoing call and measures the time between sending the SETUP and receiving the ALERT or CONN. The ARGUS disconnects automatically as soon as the measurement is completed. In the Single tests menu, use the < ↓ > to select Time measuring. Use the < ↓ > to select Conn.setup time. Enter - or select from the speed-dialing memory - the call number for the outgoing call Use the < ↓ > to select the service. Enter the B-channel on the keypad.
9 Single Tests 9.9.2 Time measurement: 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 ARGUS disconnects automatically as soon as the measurement is completed. In the Single tests menu, use the < ↓ > to select Time measuring. Use the < ↓ > to choose Interchan.dela. Enter own number for self calls or remote number for connections to a remote loopbox. Use the < ↓ > to select the service.
9 Single Tests Press to stop the measurement. If the ARGUS cannot perform the measurement, e.g. because the call number entered was wrong or no Bchannel was free, the corresponding cause will be displayed. When it is connected to a loopbox, if the ARGUS does not receive the data back within 13 seconds, it will display the message “No LOOP”.
9 Single Tests 9.9.3 Time measurement: Interchannel delay The ARGUS establishes two separate connections to a remote loopbox. The loopbox sends the respective Bchannel data back on the same channel. The ARGUS measures the propagation delay for the data on each of the B-channels and determines the difference between the two propagation delays (interchannel delay). The ARGUS disconnects automatically as soon as the measurement is completed. In the Single tests menu, use the < ↓ > to select Time measuring.
9 Single Tests If the ARGUS cannot perform the measurement - e.g. because the call number entered was wrong or no Bchannel was free - the corresponding cause will be displayed.

10 Connection Note regarding the entry of the call number Separate the extension from the access number with a # (e.g. 02351 / 9070-20 is entered on the ARGUS as: 023519070 #20). 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.
10 Connection 2) Enblock In en-bloc signalling, the ARGUS sends the entire dialing information in one block. The number is dialed from the call number memory (see “Saving Call Numbers” on page 129.). In the Single tests menu, use the <↓ > to select Phone / connec. Use the < ↓ > to select Enblock signalling.

The discharge procedure takes up to 6 hours.
17 Testing Features with the Keypad 17 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.
