ARGUS 1 Introduction The ARGUS 125 premium ISDN tester is a combitester which has not only the test functions needed to support the installation and maintenance of BRI, 2Mbit/E1, PRI and Uinterface accesses but also those needed for POTS accesses. In particular, service technicians, who increasingly work on larger, networked telephone systems and switching systems, will quickly find the ARGUS 125 an indispensable tool.
ARGUS 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.? Additionally, three user-specific services can be saved in the ARGUS and tested on the access under test.
ARGUS POTS - Voltage and Polarity Measurement The Access Acceptance Report When the ARGUS is linked to a PC via the USB (or optional serial) interface, it is, as an example, possible - with the aid of WINplus - to create and print a comprehensive test report on the PC. Testing Features via 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.

ARGUS 6 Start-Up Using the included cable connect the ARGUS to the access to be tested and then switch the ARGUS on by pressing the -key. The ARGUS displays the access and mode parameters which were last selected. Indicates the level of the accumulators’ charge when the ARGUS is operated without the power supply. Type of access Operating mode Current assignment of the softkeys Accu Servicing, see page 136 Activation of the displayed parameter.
ARGUS In the Access menu, use the cursor keys to select which type of physical access is to be tested. Afterwards, the Access Mode menu will open automatically (see chap. 8 page 33). Name of the menu Marked Access Mode Using the cursor keys, you can scroll down. The ARGUS will set the type of access to the one marked with the . Press Afterwards, the ARGUS will start the initialisation phase.
ARGUS Initialization phase: - Intialization on a BRI or U-Interface access Next the ARGUS will setup Layer 1. While it is setting up Layer 1, the “L1 Sync” 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 “L2 Rx/Tx” LED will light.
ARGUS Example: State display on a BRI access The ARGUS displays the following: - Access type (e.g.
ARGUS - Initialization on a PRI access As soon as Layer 1 is successfully setup, the “L1 Sync” LED 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 “CRC4 mode” on page 123.). The ARGUS will begin to automatically determine the access configuration. After Layer 2 is setup, the “L2 Rx/Tx” LED will also light.
ARGUS An example: State display on a PRI access The ARGUS displays the following: - Type of access - Access Mode - Bus configuration: - D-channel protocol - The availability of the B-channels Available B-channels: The light squares indicate the available B-channels and are ordered in six blocks of 5. The upper row of squares represent the B-channels that are available for outgoing connections, the lower row represents those that can be used for incoming calls.
ARGUS - State display on a POTS access The ARGUS will display the voltage when idle. - State display on a U-interface access The ARGUS will display - the type of access - the access mode - the D-channel protocol - the U-interface variant - the availability of the B-channels and - the voltage when idle.
ARGUS The ARGUS Main Menu For clarity, all of the available “actions” (commands) are logically organised in menus. All of the menus, which are available for the type of access under test, are listed in the Main menu. ARGUS State display Repeat the B-channel test. Main menu Marked menu The display currently shows the top line of the list. The list continues. Using the cursor keys, you can scroll down. to have the ARGUS open the menu marked with the . Press Press to select a menu.
ARGUS Using the numeric keys to start a test or function: Using the numeric keys, you can start important ARGUS functions directly, regardless of the currently active menu level: BRI and PRI accesses: Numeric key 2 Start the service check (see page 71) Numeric key 3 Start the suppl.serv.test (see page 66) Numeric key 4 Start the AutoTest (see page 103) Numeric key 5 Send test results to a PC: The measurement report Start connection last saved or displayed will be sent to the connected PC.
ARGUS 7 Setting the Type of Access If the parameters displayed at power on are not accepted, the Access menu will open automatically. However, you can also open the Access menu at any time from the Main menu. In the Access menu, the user must select the type of physical access to which the ARGUS is actually connected. When the ARGUS is restarted, the settings used last will be suggested as the default.
ARGUS 8 Selecting 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. Using the cursor keys, select the desired Access mode. Confirm the Access mode The ARGUS will open the State display. 8.1 Operation on a BRI, U-Interface or PRI access 8.1.1 TE-Simulation mode TE automatic On a BRI or U-interface access, the ARGUS will automatically determined the Dchannel Layer 2 mode (PP or P-MP).
ARGUS 8.1.3 Permanent switch circuit (leased line) Besides dial-up connections to any subscriber, ISDN also supports the use of permanent circuits switched to a specific remote location (leased lines). These leased lines (permanent circuits) are available after setting up Layer 1, in other words after synchronizing both terminals by exchanging HDLC-frames. The location where the clock is generated can be selected see “Clock mode” on page 121.
ARGUS 8.1.3.2 BERT on leased lines (permanent circuits) On a BRI access: A number of variations are possible in testing the permanent circuit with the bit error rate test. In the simplest case, a B-channel loop will be set up at the remote end. 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.
ARGUS On a PRI access: In the case of a PRI access in end-to-end mode (see page 59 and page 64), a BERT can be run - in the D-channel - in a B-channel (channel selection: B-channel (64k)) - in two B-channels (channel selection: B-channel (128k)) - MegaBERT framed (optional: in all B-channels and in the D-channel) - MegaBERT unframed (optional: all B-channels, the D-channel and time slot 0) Select a channel The channel select mask will open.
ARGUS The ARGUS can be used as a loopbox on a leased line (permanent circuit). Select a channel Activate loopbox Channel selection: The ARGUS will loop either one B-channel (Channel selection: B-channel) or all B-channels and the Dchannel (Channel selection: All framed). In the case of a PRI access, you can also choose “All unframed (optional)” in the channel selection: in which case the ARGUS will loop all B-channels, the Dchannel and time slot 0.
ARGUS 8.1.3.3 Time measurements on leased lines B-channel delay The ARGUS places a call to a remote loopbox and measures the propagation delay for the data in the selected B-channel. The measurement (continuous measurement) must be terminated manually. ARGUS in the Single tests menu B-channel select Enter the B-channel from the keypad (first press ) or use the cursor keys to set the B-channel.
ARGUS Interchannel delay The ARGUS establishes two separate connections to a remote loopbox. The loopbox sends the respective B-channel 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 measurement (continuous measurement) must be terminated manually.
ARGUS 8.1.3.
ARGUS 8.1.4 BRI/PRI Monitor The ARGUS accepts all of the D-channel signals from the BRI or PRI access and sends these D-channel signals over the serial interface to a PC, which must be running ARGUS WINplus or WINAnalyse. The bus and Layer 1 are not influenced by the monitoring. Monitoring a BRI access ARGUS State display Monitoring is not yet active! Start monitoring The ARGUS displays the recording time in h:min:sec and the number of recorded signals. Stop monitoring.
ARGUS Simultaneous call display while monitoring a BRI access While monitoring, the ARGUS will search through 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 channel used (in the example, B01), the service (in the example: Speech), the own number (in the example, 61) and the destination number (in the example, 33).
ARGUS Listening-in when monitoring is not active ARGUS State Monitoring is not active.
ARGUS Monitoring a PRI access: In the ISDN Configuration menu (see page 122), you can choose whether the ARGUS should monitor the D-channel or just Layer 1 (setting not supported in connection with the V5 option).
ARGUS Display of the L1 Status in PRI Monitor mode The L1 status function is only available in PRI Monitor mode. The Layer 1 alarms and messages are presented in several windows, which permit detailed statements regarding the state of the PRI access and the transmission line (For further information, see the CCITT/ITU guidelines G.703 and G.704). The ARGUS is in PRI Monitor mode Monitoring is not active. Display of the "TE-side parameters" Use the cursor keys to scroll through the display.
ARGUS 8.1.5 BRI / PRI Recorder In 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 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 Flash memory is full, the ARGUS will automatically overwrite the oldest data.
ARGUS 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. Display the call parameters of the last SETUP received (see page 42).
ARGUS 8.1.5.1 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 - PC load session - Internal decoding - Reset Flash - Info 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 “PRI Recorder” mode.
ARGUS In the ARGUS, the storage in the internal Flash is organized as a ring buffer, which can hold the data from a series of several sessions (i.e. independent trace recordings). At the start of each session, the date and time will be written in the ring buffer. The “PC load session” function transfers all of the data session-by-session to the PC on which either WINplus or WINanalyse must be running. The time and date that the session was started will be displayed in WINplus/WINanalyse.
ARGUS Internal decoding The ARGUS will decode the D-channel data stored in the Flash memory. The ARGUS is in “PRI Recorder” mode. However, it is not yet recording! Display the signals sent to the network “<” and to the user “>” Use the cursor keys to scroll through the display. < DECODE > Display a detailed presentation (3 levels max.
ARGUS The Reset Flash function will delete the entire contents of the data Flash memory. The ARGUS is in “PRI Recorder” mode. However, it is not yet recording! Query whether the contents of the Flash memory should be deleted. < YES > Delete the contents of the Flash memory. The procedure can take several seconds. The ARGUS will show the progress of the procedure as the percentage deleted.
ARGUS 9 Operation on a POTS access 9.1 The ARGUS as a POTS terminal The ARGUS in its Main menu The Argus behaves like a POTS (analog) terminal. 52 For information on setting up a call, see page 53. < MENU > The ARGUS will return to the Main menu.
ARGUS 9.2 Connection on a POTS access Outgoing Calls The ARGUS sets up a connection to another terminal. If the terminal is a telephone, the handset integrated in the ARGUS can be used to hold a conversation. In the Main menu, use the cursor keys to select Single tests or press the key. Setup the connection Enter the number on the keypad. Each of the number's digits will be dialed individually. The ARGUS will display the number dialed.
ARGUS Incoming Call The ARGUS signals an incoming call both audibly and on the display. If the access supports CLIP, the ARGUS will display the number of the caller (see “CLIP mode” on page 128.).
ARGUS 9.2.1 POTS monitor Essentially, the POTS (analog) monitor provides a high impedance tap that does not influence the interface. You can listen to the line with the integrated handset without having the ARGUS send on or otherwise influence the interface. The ARGUS in its Main menu The ARGUS displays the voltage level on the line when it is “on hook” (not busy).

ARGUS 10 Tests on an ISDN Access 10.1 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.
ARGUS 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.
ARGUS 10.1.1 Start BERT The following parameters are required for the BERT: BERT time default duration = 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 = 10-06) HRX value Hypothetical reference connection in %, see the ITU-T G.
ARGUS After the ARGUS has setup the connection and synchronied the send and receive directions, it will display the bit pattern, the B-channel used (e.g. B1), the synchronicity of the bit pattern (synchronous or asynchronous), the sync time in h:min:sec (time in which the ARGUS can sync to the bit pattern), the LOS counter and the number of bit errors that have occurred.
ARGUS Use the cursor keys to scroll through the results. Display of the G.826 characteristic values Return to the previous display Characteristic values in accordance with ITU-T G.821 / G.826 HRX Defines the hypothetical reference connection EFS Error Free Seconds: The number of seconds in which no error occurred. ES821 Errored Seconds: The number of seconds in which one or more errors occurred. SES821 Severely Errored Seconds: The number of seconds in which the bit error rate is >10-3.
ARGUS 10.1.1.1 BERT - saving The ARGUS can store the results of several BERTs. The ARGUS saves the results together with the date, time and call number of the access under test (if this number is entered as the "own" number in the speed-dialing memory) under the next free record number (see page 101). If all of the records are used, the ARGUS will return to the Autom. Test dialog and request permission to overwrite the oldest test results.
ARGUS 10.1.1.2 Display the saved BERT results The ARGUS in its Main menu Use the cursor keys to select the record in which the BERT has been saved (in the example: record 1 with the record name 0235190700) ARGUS State display The ARGUS will first display the status of the access under test. Display of the Display of the saved results (see page 107).
ARGUS 10.1.2 BERT wait In “BERT wait” mode, the ARGUS will wait for the BERT at the remote end which is necessary for an end-to-end test: ARGUS in the Single tests menu Activate “BERT wait” 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. < TM > Opens the Test Manager (page 96) The ARGUS displays that will appear are the same as those in Chapter 10.1.1 Start BERT .
ARGUS 10.1.3 B-channel loop “B-channel loop” mode is required in order to run a bit error test using a loopbox at the remote end as well as to test leased lines. ARGUS - Single tests menu Activate the "B-channel LOOP“ The ARGUS will wait for a call. Any incoming call (regardless of the service) will be taken immediately. The ARGUS will switch a loop back in the B-channel that is specified by the exchange and then send the recieved bit pattern back to the caller/sender.
ARGUS 10.2 Test the Supplementary Services The ARGUS checks whether the access under test supports supplementary services in 1TR6 or DSS1 protocol. 10.2.1 Suppl. Services Test for the 1TR6 Protocol The ARGUS in its Main menu Start the test The test results are displayed automatically: += suppl. service supported - = suppl. service not supported Use the cursor keys to scroll through the results The ARGUS returns to the Single tests menu.
ARGUS 10.2.2 Suppl.service interrogation in DSS1 In the Single tests menu, use the cursor keys to select Service test. Enter own number Select service 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 133.). The ARGUS will test the availability of the supplementary service (in part by placing a call to itself).
ARGUS CLIP (CLIP, CLIR, COLP, COLR) In this test, 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.
ARGUS CCBS CCBS-T / Will the access under test automatically recall a remote subscriber, if the CCNR CCNR-T / Will the access under test automatically recall a remote subscriber if the MCID number called was busy? call was not answered? 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.
ARGUS 10.2.3 Supplementary 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). Example: The error code 28 belongs to the error class "wrong or invalid number".
ARGUS 10.3 Service test The ARGUS checks, which of the following services are supported by the access under test: Service Name displayed on the ARGUS Language Language Unrestricted Digital Information UDI 64kBit 3.1 kHz Audio 3.
ARGUS ARGUS in the Single tests menu Enter own number Enter the number of the access under test Service test starts 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.
ARGUS Interpreting the test results: Display Explanation ++ The self call functions OK or the remote end can take the call for this service +- The call was sent successfully, however, it was rejected at the remote end due to a lack of authorization. (Error class D in a B-channel message e.g.
ARGUS 10.4 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 set up 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 set up a D-channel connection and an X.31 connection. The duration of this connection is determined by the user (or the opposing end).
ARGUS In the Single tests menu, select the X.31 test. Use the cursor keys to select Automatic. Use the cursor keys to select D-channel. Start the test The test can take up to 4 minutes (a rotating bar will be displayed). The ARGUS will display the currently tested TEI, the previously tested TEI and the results: OK = X.31 is available for this TEI NOK = X.31 is not available for this TEI After the test is completed, the ARGUS will show whether the X.
ARGUS 10.4.2 Manual X.31, D-channel test In this test variant, the ARGUS first requests a TEI, LCN and an X.31 number (The ARGUS uses the values set in the configuration menu as default values (see page 130)). If a “**” is entered for the TEI, the ARGUS will automatically determine a TEI. ARGUS in the Single tests menu TEI is displayed The ARGUS displays the stored TEI (see page 130). You can edit the TEI from the keypad; If you enter **, the ARGUS will determine a TEI automatically.
ARGUS 10.5 CF Interrogation The ARGUS will check whether a call diversion has been setup in the exchange for the access under test (BRI or U-interface ). The ARGUS will show the type of diversion (CFU, CFNR or CFB) and the call diversion’s service. The display is limited to a maximum of 10 call diversions for all of the MSNs. The ARGUS will count any additionally set up call diversions. Any call diversion set up in the exchange can be cleared with the ARGUS.

ARGUS 10.9 Traffic generator (only on a PRI access) The ARGUS will automatically setup as many as 30 connections and will display which Bchannels on the PRI access are available for incoming and outgoing calls. ARGUS in the Single tests menu Enter the phone The speed-dialing memory opens. Use the cursor keys to scroll to desired the number or reenter the number on the keypad.
ARGUS Display of the status of the connections currently setup on the individual B-channels Use the cursor keys to scroll through the results. The test must be terminated manually. Stop test After the test is over, the ARGUS will display the causes for clearing the connections on the individual B-channels (see Appendices B and C page 141 / page 143).
ARGUS 10.10 Time measurements The ARGUS measures three different times: - Connection set up time - Propagation time of the data (B-channel delay) - 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. 10.10.1 Connection set up time The ARGUS places an outgoing call and measures the time between sending the SETUP and receiving the ALERT or CONN.
ARGUS 10.10.2 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 measurement (continuous measurement) must be terminated manually. ARGUS in the Single tests menu Dial the number Enter - or select from the speed-dialing memory - the call number for the outgoing call. Select service B-channel select Enter the B-channel on the keypad.
ARGUS 10.10.3 Time measurement: Interchannel delay The ARGUS establishes two separate connections to a remote loopbox. The loopbox sends the respective B-channel 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 measurement (continuous measurement) must be terminated manually.
ARGUS 11 ISDN connection The ARGUS can setup a connection for the following services: Service Name in the ARGUS display / abbreviation Language Language / Lang Unrestricted digital information UDI 64kBit / UDI 64 3.1 kHz Audio 3.1 kHz audio / 3.1k 7 kHz Audio 7 kHz audio / 7 kHz Unrestricted Digital Information with tones / display UDI-TA / UDI TA Telephony Telephony ISDN / Tel.

(see page 93 Clearing Down an ISDN Connection) - 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 ETS 300 182 standard, rather in the form of the information element DISPLAY (DSP), the ARGUS will display the DISPLAY message's character string.
ARGUS 11.2 En-bloc sending (outgoing call) In en-bloc sending, the ARGUS sends the entire dialing information in one block. The number is dialed from the call number memory (page 133). ARGUS in the Single tests menu Enter the phone number Use the cursor keys to select the number from the speed-dialling memory or reenter the number on the keypad. Delete the digit before the cursor The ARGUS will open the Outgo.call Tel.
ARGUS 11.3 Redial (outgoing call) The ARGUS will set up a call using the last number dialed. ARGUS in the Single tests menu Select service Enter the B-channel Enter the B-channel via the keypad (as the default setting, the ARGUS will suggest the last B-channel used). When entering a new B-channel, first press the DEL softkey. If you enter an *, the ARGUS will choose any B-channel that is free. The ARGUS will show whether the B-channel is available.
ARGUS 11.4 Incoming Call An incoming call can be taken at any time even when a test (e.g. BERT) is in process (see page 97). The ARGUS will signal an incoming call with an audible tone and a message on the display. On a P-MP access, you can use the Call acceptance (see “Call Acceptance” on page 124.) function to configure the ARGUS to only signal incoming calls which are addressed to the MSN that corresponds to your own call number.
ARGUS 11.5 Clearing Down an ISDN Connection or Clear the connection Open the Test Manager The ARGUS will display the cause (see the table below) of the disconnect (e.g. Normal clearing) and the location where the cause occurred (e.g. subscriber). Use the cursor keys to view additional information (e.g. charges, if available).
ARGUS Other causes are not shown in clear text, rather as decimal codes (see Appendix B and C and page 141 and page 143).
ARGUS 11.6 Testing Features with the Keypad This feature is only relevant on 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 socalled Keypad-Elements are imbedded in a SETUP message.
ARGUS 12 Test Manager The ARGUS can simultaneously start several tests or “connections” fully independently of each other on the ISDN access under test. As an example, a BERT can be run at the same time that you make a phone call. The individual tests or “connections” use resources. All of the tests that have been started will be administered by the Test Manager. Using the Test Manager you can start new tests, switch between tests running in parallel or terminate all of the tests that are currently running.
ARGUS 12.1 Starting Several Tests to Run Simultaneously Starting a new test or connection during an existing connection An example: There is a connection on B-channel 2. During this connection, the Test Manager is opened (or started by pressing the -key. The ARGUS will display the number of existing connections (-/01). Select “Start new one” Mark “Single tests” Select the desired test (e.g. bit error test).
ARGUS Some tests use so many resources that they cannot be run in every combination with other tests. In this case, the ARGUS will display the message “Test not possible at this time”. Test/ Connection Number of times that this test/connection It is possible can be started at the same time to change to another test Incoming call 2 (30 on a PRI) Yes Outgoing call 2 (30 on a PRI) Yes BERT 2 Yes LOOP 2 Yes Service tests 1 No Suppl.serv.test 1 No Time measurement 1 No X.
ARGUS Accepting an incoming call/connection when a test is running. The ARGUS signals an incoming call both audibly and on the display (see page 87 ISDN connection). The incoming call can be accepted without influencing the currently running test. If either the B-channel loop or BERT wait function is active, the call will be accepted automatically.
ARGUS 12.2 Switching Between Tests Example: Start the Test Manager Using the cursor keys, select the Test (Connection) that you wish to switch to. The ARGUS will return to the point from which the Test Manager was called (e.g. to a test running in parallel). If no other test is running, the ARGUS will return to the Main menu. The ARGUS will return to the 12.3 Cancel All Open the Test Manager. Mark “End all”.
ARGUS 13 Test Results The ARGUS displays the saved test results. Using the Intec software, WINplus or WINanalyse, the test results can also be saved on a PC. WINplus or WINanalyse can then be used to generate a comprehensive measurement report from these results. The ARGUS saves the test results together with the date and time (from the internal clock of the ARGUS). Additionally, settings such as your own plus a remote call number will also be saved. The results are not lost when the ARGUS is switched off.
ARGUS Entering a record name: The ARGUS will save the test results in the first free record. This record can be assigned a name (default: AMP_1, AMP_2, AMP_3 .... or the call number of the access under test if the number has been entered into the speed-dialling memory, see page 133). If all of the records have been written, you must manually select a memory location (record). The record name is entered using the numeric keypad.
ARGUS 13.1 Start the automatic test In this case, the ARGUS executes a test sequence automatically. The required parameters (e.g. measurement time and error level for the BERT see page 126) should be checked before the automatic test series is begun. Using the intec software, WINplus or WINanalyse, the test results can also be saved on a PC, where they can be presented in a comprehensive measurement report and printed.
ARGUS Automatic Start the test series from the Test reports menu. If the automatic test series is started by pressing function key 4, you must first enter a name for it to be saved under. Select a memory location (record) Select “Start” Accept the suggested record name or enter a new name (see page 102). Enter own number Select service Enter Own number; on accesses using the DSS1 protocol, also enter the remote number. Use the cursor keys to select the service. (required for the suppl.serv.
ARGUS Terminating the test (early): Interrupt the automatic test The ARGUS will terminate the test sequence, any test results already gathered will be lost. Any “old” data stored under this data record number from a prior test will be retained. The ARGUS will return to the next higher menu. Skipping individual tests: A single test can be skipped: In this example, the ARGUS is running a Service check. Stop the current single test The ARGUS will jump to the next single test (e.g. to the BERT).
ARGUS Resuming a test: The ARGUS can resume an interrupted single test: In this example, the ARGUS is running a Service test. Stop the current single test The ARGUS repeats the “disturbed” single test.
ARGUS 13.2 Display Results Depending on the type of access under test, the ARGUS displays the results stored for the single tests in the following order: On a BRI or U-interface access On a PRI access - Status - Status - Level measuring - Service tests - Service tests - BERT - BERT - L1 counter and measurement time - Supplementary Services Test - Supplementary Services Test - X.31 test - X.

ARGUS 15.2 The L1 Status of a PRI Access The ARGUS displays the Layer 1 alarms and messages, which provide detailed information regarding the state of the PRI access and the transmission line (For further information, see the CCITT/ITU guidelines G.703 and G.704). The ARGUS in its Main menu The ARGUS displays the time that has elapsed since the ARGUS was initially started or it was last reset in minutes and seconds (05:18). The measurement time and all Layer 1 alarms and messages are updated continuously.
ARGUS The meaning of the individual displays: Signal The ARGUS has received the correct 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 (swapped) an " X" will be displayed.".
ARGUS 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.
ARGUS 16 Settings The ARGUS can be configured to suit your special requirements. The default (factory) settings can be restored by selecting “Reset” (see page 134 Reset). 16.1 PC/Trace The ARGUS remains active and either saves the data from the D-channel (all of the Dchannel messages sent to and received from the network) in its internal Flash memory or passes the data directly to the connected PC. The Remote function is optional. The ARGUS in its Main menu Auto PC sync.
