6 Start-Up Select a type of access Press In the Access menu, use the cursor keys to select which type of physical access is to be tested. The Access mode menu will open automatically (with two exceptions: X.21 and Copper line test). (see chap. 9 page 34). Name of the menu Marked Access Mode Press Press Press 24 The ARGUS will set the type of access to the one marked with the . Afterwards, the ARGUS will start the initialisation phase.
6 Start-Up Initialization phase: - Initialization on a BRI or U-interface access (optional) or as a BRI NT simulator: 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, the “L1 Sync” LED will light continuously.
6 Start-Up Example: State display on a BRI access The ARGUS displays the following: - Access type (e.g.
6 Start-Up - 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” page 133.). The ARGUS will begin to automatically determine the access configuration. After Layer 2 is setup, the “L2 Rx/Tx” LED will also light.
6 Start-Up An example: State display on a PRI access The ARGUS displays the following: - Type of access, Access mode, Bus-configuration and D-channel protocol: - The availability of the B-channels Available B-channels: The light squares indicate the available B-channels and are ordered in two blocks of 15. 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.
6 Start-Up - State display on a POTS access The ARGUS will display the voltage when idle. - State display on a U-interface access The ARGUS displays the Access mode, the Dchannel protocol, U-interface variant, the availability of the B-channels and the voltage when idle.

7 Setting the Type of Access 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.
8 Copper Line Tests 8 Copper Line Tests Connect the ARGUS (Line jack) to the access to be tested and then switch the ARGUS on. The line must be voltage-free (out of service) for this measurement! Open the Main menu and use the cursor keys to select the Access menu. The ARGUS will first measure the resistance. If the resistance test shows that the line is open (infinite resistance), the ARGUS will measure the capacitance. The ARGUS displays the measured resistance.
9 Selecting the Access mode 9 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. 9.1 Operation on a BRI, U-Interface or PRI access 9.1.
9 Selecting the Access mode 9.1.3 Permanent switch circuit (leased line) Besides dial-up connections to any subscriber, ISDN also supports the use of leased lines (circuits permanently switched to a specific remote location). 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 page 131 Clock mode).
9 Selecting the Access mode 9.1.3.2 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.
9 Selecting the Access mode On a PRI access: In the case of a PRI access in end-to-end mode (see “Bit error test” page 71 and page 79 “BERT wait”), a BERT can be run - in the D-channel - in all B-channels - in all B-channels and in the D-channel (all framed) - in selected B-channels - in all channels and time slot 0 (all unframed) The channel select mask will open. In this mask you can chose from 3 predefined channel patterns: - MegaBERT framed (default: all B-channels and the D-channel) - MegaBERT unfr.
9 Selecting the Access mode Start BERT When “Selection” is chosen, the BERT will start as soon as a channel pattern is entered. Set the channel pattern Start BERT Editing the selected channel pattern: Time Slot 0 DChannel Available B-channels ordered in two blocks of 15.
9 Selecting the Access mode The selected channels are indicated in the upper row by black squares. The marked squares in the lower row indicate the current position of the cursor. The cursor is moved with the horizontal cursor keys: The channels can also be marked with the cursor directly using the numerical keypad: If you enter the digits 08, the cursor will jump to B-channel 8. If you press the *, the cursor will move to time slot 0 while pressing the # will move the cursor to the D-channel.
9 Selecting the Access mode No B-channel has been selected; the cursor is sitting at B-channel 10. Mega BERT framed Select all channels except time slot 0. The cursor is sitting at time slot 0. Mega BERT unframed Select marked channel (time slot 0) Time slot 0 is selected (TS0:+) and is still marked by the cursor (both squares are marked). The channels 5 to 8 were individually marked with the cursor and selected with ; the cursor is at B-channel 8.
9 Selecting the Access mode 9.1.3.3 Loopbox with a permanent circuit 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” in the channel selection: in which case the ARGUS will loop all B-channels, the D-channel and time slot 0.
9 Selecting the Access mode 9.1.3.4 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 scroll through all of the B-channels.
9 Selecting the Access mode 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.
9 Selecting the Access mode 9.1.3.
9 Selecting the Access mode 9.1.4 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 h:min:sec and the number of recorded signals. in Stop monitoring.
9 Selecting the Access mode 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).
9 Selecting the Access mode The ARGUS can passively listen-in on both the network-side and the terminal-side. B-channel select Enter the B-channel Listening-in to stop listening-in. The ARGUS will return to the Main menu.
9 Selecting the Access mode Monitoring a PRI access: In the ISDN Configuration menu (see page 132), you can choose whether the ARGUS should monitor the D-channel or just Layer 1 (setting not supported in connection with the V5 option).
9 Selecting the Access mode 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.
9 Selecting the Access mode 9.1.5 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.
9 Selecting 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. Display the call parameters of the last SETUP received (see page 45).
9 Selecting the Access mode 9.1.5.1 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.
9 Selecting the Access mode PC load session 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.
9 Selecting the Access mode 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.
9 Selecting the Access mode Reset Flash 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.
9 Selecting the Access mode 9.1 Operation on a POTS access 9.1.1 The ARGUS as a POTS terminal The ARGUS in its Main menu The Argus behaves like a POTS (analog) terminal. 56 < TALK > For information on setting up a call, see page 104. < MENU > The ARGUS will return to the Main menu.
9 Selecting the Access mode 9.1.2 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).
10 Operation on an X.21 Access 10 Operation on an X.21 Access The ARGUS will perform a bit error test on the X.21 access in accordance with the ITU guidelines G.821 and G.826. Besides the measurement results, the ARGUS will also display the X.21 data rate. Plug the adapter cable into X.21 jack to connect the ARGUS to the X.21 network.
10 Operation on an X.21 Access 10.1 Start BERT The ARGUS will detect the clock of the X.21 permanent circuit, calculate the data rate and then automatically search for the channels used. On these channels, the ARGUS will send the test pattern (see page 137 Bit pat. X.21) selected, receive it again and evaluate it in accordance with the ITU guidelines G.821 and G.826 (loopbox required at the remote end).
10 Operation on an X.21 Access Stop the BERT When a bit error is detected, this will be signaled by a brief alarm (if the alarm is enabled); in the event that the synchronisation is lost, a constant alarm will sound. The alarm bells can be switched off (see, page 144). 10.1.1 Display the test results After the test is completed, the ARGUS will display the following test results: The test results display: The evaluation of the results depends on the error threshold (OK).
10 Operation on an X.21 Access 10.1.2 Saving the test results in the ARGUS Display the results Save the result? < YES > The ARGUS saves the results. Use the keypad to enter the name under which the results should be saved (Default: AMP_1, AMP_2....
10 Operation on an X.21 Access 10.2 BERT wait In this mode, the BERT will wait for the BERT at the remote end which is necessary for an end-to-end test: see “BERT wait” page 79.
11 Tests on an ISDN Access 11 Tests on an ISDN Access 11.1 Test the Supplementary Services The ARGUS checks whether the access under test supports supplementary services in 1TR6 or DSS1 protocol. 11.1.1 Suppl.serv.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.
11 Tests on an ISDN Access 11.1.2 Suppl.service interrogation in DSS1 In the Single tests menu, use the cursor keys to select Service test. Enter own number Select service Select a B-channel Select 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” page 145.). The ARGUS will test the availability of the supplementary service (in part by placing a call to itself).
11 Tests on an ISDN Access 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.
11 Tests on an ISDN Access CF In this test, the ARGUS will check whether the 3 supplementary services (CFU, CFU, CFB and CFNR are supported.
11 Tests on an ISDN Access 11.1.3 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".
11 Tests on an ISDN Access 11.2 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.
11 Tests on an ISDN Access 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.
11 Tests on an ISDN Access 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.
11 Tests on an ISDN Access 11.3 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.
11 Tests on an ISDN Access 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 page 79 BERT wait). A bit pattern is sent to this tester. Independent of the received bit pattern, the remote tester uses the same algorithm to generate the bit-pattern that it sends back.
11 Tests on an ISDN Access 11.3.1 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.
11 Tests on an ISDN Access 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.
11 Tests on an ISDN Access 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 evaluation of the results depends on the error threshold (OK). Transferred data (K= 1024* bits, k=1000*Bit), sync.time LOS counter abs.err: The number of bit errors rel. err: The bit error rate (e.g. 9.7E-07 = 9.7·10-7 = 0.
11 Tests on an ISDN Access AS Available Seconds: The number of all 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. In one minute, 3,840,000 bits are transferred, thus a BER = 10-6 corresponds to 3.84 bit errors (3 errors = NO (no Degraded Minutes), 4 errors = OK (Degraded Minutes). LOS Loss of Synchronisation: Synchronization is lost at an error rate > or = 20% within a second.
11 Tests on an ISDN Access 11.3.1.1 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 111). 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.
11 Tests on an ISDN Access 11.3.1.2 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 access number 0235190700) ARGUS State display The ARGUS will first display the status of the access under test. < CONTI. > Display of the results 78 Display of the saved results (see page 117).
11 Tests on an ISDN Access 11.3.2 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.
11 Tests on an ISDN Access 11.3.3 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.
11 Tests on an ISDN Access 11.4 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.
11 Tests on an ISDN Access In the Single tests menu, select the X.31 test The ARGUS will open the menu for editing the profile containing the X.31 parameters (see page 140). Use the cursor keys to select Automatic. Use the cursor keys to select D-channel. Start the test X.31 test running 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.
11 Tests on an ISDN Access 2) B-Channel - Case A For this X.31 test variant, the ARGUS requires the entry of a call number for the D-channel connection, a B-channel and the X.31 number; The ARGUS will use the number saved in the profile as the default value (see page 140) and the “X.31 test number” from the speeddialling memory (see page 145). ). The ARGUS will first set up a D-channel connection and then attempt to set up a X.31 connection on the B-channel.
11 Tests on an ISDN Access B-Channel - Case B This test is identical with the “B chan. case A” test, except that it is not necessary to enter a D-channel call number. The ARGUS will first setup a D-channel connection (via the service) and then attempt to set up a X.31 connection on the B-channel. 11.4.2 Manual X.31 Test There are three possible variants of the Manual X.31 Test: 1) D-channel In this test variant, the ARGUS first requests a TEI, LCN and an X.

12 Connection Procedure for an Incoming Call (ISDN) An incoming call can be taken at any time even when a test (e.g. BERT) is in process (see page 107). 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” page 134.) function to configure the ARGUS to only signal incoming calls which are addressed to the MSN that corresponds to your own call number.
12 Connection 12.2 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).
12 Connection Other causes are not shown in clear text, rather as decimal codes (see Appendix B and C page 158 and page 160 ).
12 Connection 12.3 Operation on a POTS Access Procedure for an Outgoing Call (POTS) 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.
12 Connection Procedure – 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” page 138).
13 Test Manager 13 Test Manager The ARGUS can simultaneously start several tests or “connections” fully independently of each other on the 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.
13 Test Manager 13.1 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 displays the number of existing connections (-/01). Use the cursor keys to select “Start new one”. Use the cursor keys to select “Single tests”. Using the cursor keys, select the desired test. (e.g. BERT).
13 Test Manager If a test (or connection) is cancelled/cleared, the ARGUS will return to the Test Manager if there is another test (or connection) running in the background. 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”.
13 Test Manager Accepting an incoming call/connection when a test is running. The ARGUS signals an incoming call both audibly and on the display (see page 96 Setting up an 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.
13 Test Manager 13.2 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).
