1 Introduction to the GeoProbe User Course
The GeoProbe User Course Training Manual This manual explains the features and functions required to perform network monitoring and surveillance tasks. The training manual is based on Inet’s GeoProbe training network, a fictitious network named Tejas. The Texas theme is used throughout the documentation for student exercises (called labs). The Texas state map is used as the geographical background for the Tejas network, and the DallasFort Worth map is used for the background in detailed maps. SS7 nodes and GeoProbe elements are located in various cities around Texas.

1 Introduction to the GeoProbe User Course
Student Labs Each chapter includes hands-on labs. Since all students are concurrently writing to the same GeoProbe database, it is necessary to use different names when performing configuration. Each workstation is assigned a unique number. Wherever a # is included as part of a task or lab, it indicates the workstation number should be used in place of the #. This appears in labs as , such as . If this was for workstation 2, the actual name would be , replacing the # with a 2. It is critical to use this number to avoid conflicts in recalling data or writing to the database. In a real-time environment, multiple people would not be configuring the same portions of the database at the same time. For training at a customer location, certain labs may be skipped, as they could have an adverse effect on the live GeoProbe database. This manual is intended for training purposes only. Your GeoProbe system comes with a SpIstation User Guide and a SpIstation Application Guide that contains detailed information on all SpIstation features.

2 Introduction to the GeoProbe
The GeoProbe System The GeoProbe System is a UNIX-based surveillance, network configuration, and system administration tool for monitoring SS7 networks. The GeoProbe monitors every call in an SS7 network and gathers network data. This platform is ideal for customized billing schemes, fraud management, generation of call detail records, marketing, and other high-level management applications. The GeoProbe monitors SS7 performance via SpIprobes. These monitoring platforms collect data from nodes and linksets and deliver this information to the SpIstation where the user can display and evaluate it with intuitive point-and-click commands and menu options. Problems in the network trigger alarms that are displayed through flashing and color change, based on the severity of the alarm. A few clicks of the mouse display details about the alarm, and a few more clicks provide access to network data. This interface allows network-wide surveillance and troubleshooting from a central facility. The monitoring and surveillance functions of the GeoProbe System are available at the SpIstation through an easy-to-use graphical user interface (GUI). The GUI can be based on geographical maps of the SS7 network. Users click on icons representing network elements to configure the system or retrieve information.

2 Introduction to the GeoProbe
The SpIprobe can process data for a maximum of 256 links @ 1 Erlang per link, or can be deployed with additional SpIprobes “daisy-chained” together to support a maximum of 1024 links @ reduced Erlangs per link. Because of its ability to process a large number of links, SpIprobes are usually deployed at STP sites and can process data for links connected to the STP. Figure 2.4 shows SpIprobes monitoring links at STP sites.
Figure 2.4 - SpIprobe Monitored Links at an STP
The SpIprobe includes processing for various GeoProbe applications, such as ReMon, Mass Call, and Billing. The SpIprobes perform most of the SS7 data collection and processing for the GeoProbe system.

2 Introduction to the GeoProbe
SpIserver The SpIserver provides centralized storage and management of the entire GeoProbe system. The SpIserver requests and stores network data collected by the SpIprobes in the form of statistics, alarms, and reports. This data is distributed to appropriate users at SpIstations or to external systems. The GeoProbe configuration database is stored at the SpIserver. The SpIserver also allocates resources to users for various applications, such as ReMon or User Call Trace. Only one SpIserver is required for the entire GeoProbe network, but systems can have multiple and/or redundant SpIservers. Figure 2.5 shows a typical SpIserver (the Sun SPARCserver 1000).

2 Introduction to the GeoProbe
Transport Network The Transport Network connects the SpIprobes, SpIserver, SpIstations, and external systems via TCP/IP over X.25 or Ethernet. The SNMP (Simple Network Management Protocol) is used for communications between the SpIprobes and the SpIserver.
Transport Network
Getting Monitored Data to the SpIstation All GeoProbe configuration is done at the SpIstation. The System Administrator defines the network data the monitoring equipment is to collect. This is done by configuring the GeoProbe network maps, and by defining alarms, statistics, and other application requirements from the SpIstation. This information is then downloaded to the SpIprobes. SpIprobes collect network data as required. This data is then sent to the SpIserver. Based on alarm profiles, user profiles, and other configuration information, the SpIserver stores the data or distributes it to the SpIstations in the form of alarms and statistics as shown in Figure 2.7.

2 Introduction to the GeoProbe
Network Surveillance Applications A number of applications are available within the GeoProbe system for troubleshooting and diagnosing problems. These applications are described in the following section. Remote Monitoring (ReMon) Application The Remote Monitoring (ReMon) Application is a network-wide protocol analysis tool that allows users to capture signal unit traffic (filters) from any combination of links, linksets, or monitored nodes in the SS7 network. Users can then view the data in mnemonic or plain-English text mode at the SpIstation. The ReMon Application includes tools for post-capture analysis of data, including:
Save/Recall of captured signal unit data
Search, View, Filter SUs
User Call Trace Application The User Call Trace Application uses the Call/Transaction Tracking Engine. The User Call Trace Package’s intelligent filtering allows the GeoProbe system to capture only the data associated with any given call or transaction. The filter is based on a phone number or a specific Point Code. Mass Call Onset Detection Application The Mass Call Onset Detection Application detects a high number of calls suddenly delivered to the same phone number. The alarms generated are based on number of calls to a particular point code. This application is useful for detecting events which could cause an SSP to become congested. Inet Technologies, Inc.

2 Introduction to the GeoProbe
SUDStore Application The SUDStore (Signal Unit Data Storage) Application allows continuous capture of SS7 link SU data in independent, scrolling hard disk buffers at the SpIprobe. This stored data can provide vital troubleshooting information. Failed Call/Transaction The Failed Call/Transaction application is similar to SUDStore, but only Signal Units from Failed Calls or Transactions are stored on disk at the SpIprobe. The conditions for defining a call or transaction as failed are based on user-specified parameters.
Data Collection and Forwarding Applications The GeoProbe system provides several applications to track SS7 usage, generate billing aggregations, and report network fraud. Usage Measurement Application The SS7 Usage Measurement Application tracks SS7 usage measurements and can generate billing aggregations. Billing aggregation may be performed in accordance with relevant specifications, such as Bellcore’s TA-NWT-001087, or may be user-defined to create custom billing schemes with any SS7 parameter combination as aggregation grouping keys. The aggregated data is output through a port to a user-selected accounting center, where further processing and invoicing functions are performed.

2 Introduction to the GeoProbe
MSU Forwarding Application The MSU Forwarding Application allows a user to forward raw signal unit data (MSUs) from the SpIprobe to an external system for further processing, analysis, or distribution. The data is forwarded using TCP/IP. Call Detail Record (CDR) Application The Call Detail Record Generation Application extracts key parameters from call setup messages, formats them into records, and routes them to a back-end system for aggregation and processing for other applications such as billing or fraud management. CDRs generated specifically for fraud purposes are transmitted to a customer or third party fraud application. This application is based on the CDR generation capabilities of the GeoProbe system. Fraud records are generated upon call termination. Development Tools The OpenSeven Application Programming Interface allows users to develop custom software on the GeoProbe system. OpenSeven API-Extension This program allows software to be written on a UNIX workstation and provides access to the various GeoProbe applications. OpenSeven API-Interpreter This program allows users to define SS7 protocol messages with proprietary message types and parameters down to the formats and codes of specific field. In addition, it allows the building of custom call scenario state machines to be used by the various performance monitoring and call trace applications. Inet Technologies, Inc.

SpIstation Drag and Drop In several SpIstation windows, it is necessary to select icons from maps, and drag them to a location on the setup window. This feature is called “Drag and Drop”, and the location to which you are assigning the dragged item is called the “Drop Box”. In the previous lab, a box appeared to the right of the window when an item was added from a list of options. If you followed the steps in the previous labs, this label should say Links. This box is a drop box for links selected from a network map. To the left of the drop box is a label indicating the name of options that are added. To drop links in the drop box, it is necessary to display both the network map and the window containing the drop box. 1. Rearrange and resize the windows on your screen so that both the Links drop box and the Tejas_2 network map display. 2. On the Tejas_2 network map, use your left mouse button to select the linkset between the Amarillo STP and the El Paso SSP. Then, select the linkset between the Laredo STP and the El Paso SSP. After both linksets have been selected, press your middle mouse button, and hold it down while moving the mouse to the center of the Links drop box. If done properly, the icon changes to the Drag and Drop icon. As you move the Drag and Drop icon into the drop box, it changes, indicating you are in the drop box. The icon has a small arrow in it. If you do not get a drag and drop icon, it may be that no item was selected or the selected item was invalid.

Network Configuration Mode The SpIstation network is a graphical representation of a company’s actual SS7 network and the GeoProbe equipment that monitors the SS7 network. This graphical network typically consists of several different map displays. SpIstation users monitoring different aspects of the SS7 network can use different geographical maps and views displaying different network elements. The GeoProbe Administrator must create this graphical network before SpIstation users can begin network surveillance.

The network map consists of two parts: the background map and the network diagram. The background map is the geographical map of the area, region, or country that forms the basis for the network map. The network diagram is the arrangement of icons representing the SS7 network and the monitoring equipment. In the Configuration Mode of the SpIstation, GeoProbe Administrators place icons representing the nodes and SpIprobes and SpInodes of the SS7 network on geographical background maps. They then draw color-coded lines representing linksets to connect the nodes. The GeoProbe Administrator must plan configuration of network maps by ensuring point codes, node names, IP addresses and other information is available. Once a network map has been configured, additional information can be added at any time. Refer to the SpIstation User Guide or the GeoProbe Administration course for more information regarding the System Administration and Network Configuration Modes.

5 Network Status and Performance Monitoring
Network Status Mode Introduction The SS7 network is monitored in the SpIstation Network Status Mode. In the Network Status Mode, the SpIstation displays network maps with icons representing monitored nodes and linksets. A problem or potential problem detected in the network triggers an alarm. Icons representing the affected network elements change color on network maps to alert the user. Users can then access detailed alarm information, and respond as required. The Network State Display and the Bull’s-eye offer additional options for monitoring the SS7 network. The Network State Display provides real-time information on the status of network elements, and the Bull’s-eye offers ways to view network alarms without having to access the Network Status Mode. This chapter explains how to use the Network Status Mode, Network State Display, and the Bull’s-eye for monitoring network status and performance.

Network Status Map Views Maps can be assigned View options, or “filters”, that display only certain elements on the map. Multiple views can be created and used on multiple maps. Each user can set a default view for each map and for their user ID. Setting a default view affects the current map. Default Views can be Current View, No View, or Fallback View.
If a Fallback View is set in the View Editor, it is used for maps without assigned Default Views for that user ID. The Fallback View can be assigned as the Default View for a map.
The Current View option assigns a currently applied map view as the Default View.
The Default View can be set as No View for a map, meaning that no view filters are applied.
Users can access all configured views, views defined by other members of their System Administration group, or views defined by their own user ID. When a view is applied to a map, it will display in the title bar next to the map name in the open map window (Figure 5.14).

5 Network Status and Performance Monitoring
Network State Display The Network State Display feature allows users to obtain realtime network status information for selected SS7 elements. Users can access information on link, route, and subsystem availability. The Link Status option displays availability of all links within selected linksets, or of all linksets connected to selected nodes. The Route Status option displays availability of network routes for selected nodes, and the Subsystem Status option lists subsystem availability for selected nodes. This feature can be accessed from the Network State Display icon on the SpImain, or from the pop-up action menu of any selected SS7 element. Selecting the State Display option from an action menu immediately launches a status display window for the selected element. If Network State Display is launched from SpImain, the user must first define SS7 elements in a setup window. This would allow the status to be displayed for multiple elements in one display window.

Linkset and Link States are based on availability information from the SpIprobe. If a linkset contains more than one link, each link within the selected linkset will have a separate entry in the Link Status Display Window. The three possible states are: •
Available indicates the link is in service.
•
Not monitored indicates the SpIprobe recognizes an unmonitored link. For example, in Figure 5.22, Dallas is not monitored, as the link between Amarillo and Dallas is not being monitored by the SpIprobe. However, since Dallas is configured in the GeoProbe database, it is recognized by the SpIprobe.
•
Unknown indicates the link or linkset is unrecognized or inaccessible by the SpIprobe
Level 2 Tx and Level 2 Rx indicates the current state of MTP Level 2.
The Monitoring Equipment field lists the monitoring equipment for the link. It gives the name of the SpIprobe and its port assigned to the link.

5 Network Status and Performance Monitoring
Alarm Display GeoProbe surveillance and performance functions continually monitor the SS7 network for events that may indicate potential problems within the network. If a SpIprobe detects such an event, an alarm is sent to the SpIserver. The SpIserver records and processes the alarm, then distributes the alarm to SpIstations to alert users of potential problems. Alarms can be reported to the user in the Network Status Mode or in the Bulls-eye Window. In the Network Status Mode, visual indications are displayed to the user on network maps. In the Bulls-eye, users are alerted to alarm events by both visual and audible indications. Network Status maps and the Bulls-eye Window both provide access to alarm logs, which provide more detailed information about the alarms. From the alarm logs, users can respond to alarms by acknowledging, clearing, or providing detailed comments about them.

5 Network Status and Performance Monitoring
Network Status Map Alarm Display Users monitor the SS7 network by opening network maps in the Network Status Mode. If an alarm event is reported to the SpIstation, users are immediately alerted to the condition by a visual change in open map windows. As discussed previously, map views can be configured to indicate alarm conditions by displaying certain map elements only if they are in an alarm state. If a user chooses to display map elements all of the time, alarms are also indicated to the user by a change in colors on the network map. Depending on the status of the alarm, the element can flash between two colors. For example, assume the following color settings for a linkset failure alarm in the Tejas network:
Linkset in-service = green
Linkset failure alarm = red
Unacknowledged linkset alarm = gray
While the linkset is in service, it will appear green on the network map. However, if a linkset failure alarm is detected, the colors can change based on the following table: Table 5.1 - Link Alarm Color Example
Linkset Alarm Status
Note: Alarm weights and colors on the Bull’seye are affected by a text file, as discussed in the GeoProbe Manager course.

Alarm Colors defined by the GeoProbe Administrator affect how alarms display on network maps. These colors are dependent on the alarm severity, the affected element, and whether the alarm has been cleared or acknowledged. Colors displayed to users are based on user alarm groups.

5 Network Status and Performance Monitoring
Alarm indications on Network Maps can vary for different users. Users belonging to the same User Alarm Group share alarm configuration and display indications. Users are assigned to alarm groups when their accounts are created in the System Administration Mode.
Alarm severity levels are assigned by the GeoProbe Administrator when alarms are configured. Alarm severity levels include Informational, Minor, Major, Critical, and Weighted. •
Informational alarms are normally used for indicating a problem has been corrected, or for automatically clearing other alarms.
•
Minor, Major, and Critical indicate the severity of the alarm. This type of alarm is not cumulative; multiple occurrences of the same type of event do not cause a higher alarm level.
•
Weighted Alarms are assigned alarm weights, or values, rather than a specific severity level, and alarm thresholds are assigned to Minor, Major, and Critical Alarm levels. If the cumulative total of alarm weights for a specific network element meets or exceeds one of these thresholds, an alarm is generated.
Alarm Clear and Acknowledgment Requirements Alarms can be configured to require clearing, acknowledgment, clearing and acknowledgment, or neither. If alarms require acknowledgment or clearing, alarm indications will not change until these actions have been completed. The Alarm Acknowledgment and Clearing processes can both be performed from the alarm log. Alarms requiring clearing can also be automatically cleared by other alarms. IMPORTANT: If a user clears and acknowledges an alarm, network maps will no longer indicate an alarm condition exists. However, clearing and acknowledging alarms on the GeoProbe Inet Technologies, Inc. Proprietary Information 992-0098-08-001-990701

does not correct the actual network problem. It is recommended that alarms not be cleared until the actual problem causing the alarm has been corrected.
Alarm Types: •
Note: The availability of Embedded Alarms and Statistical Alarm events is based on installed GeoProbe application packages.
Two types of alarms are included with the GeoProbe software, Embedded and Statistical. Embedded Alarms are pre-configured alarms installed with the GeoProbe software. Statistical Alarms are userdefined alarms which can be customized to meet specific needs.
Alarm Logs When an alarm is displayed to a user, the user must access an alarm log to view detailed information about the alarm. In the alarm log, a user responds to an alarm by clearing, acknowledging, or providing comments about the alarm condition. In the Network Status Mode, alarm logs can be displayed globally, per map, or per element.
The Global alarm log displays all alarms for all maps.
The Map alarm log displays alarms for the current map.
The Element alarm log displays alarms for the selected map element.
Global and map alarm logs can be accessed from the Alarms pulldown menu, or from the pop-up Default Action Menu, which is accessed by clicking the right mouse button on the background of an open map window. The element alarm log can only be accessed by selecting the element, then by clicking the right mouse button to get that element’s Action Menu.

The default Bull’s-eye has three rings containing one or more functional areas. The inner ring indicates link level alarms, the next ring indicates network level alarms, and the outer ring indicates application level alarms. The Bull’s-eye can be customized to display other functional areas. Bull’s-eye customizing is taught in the GeoProbe Manager course. If an alarm occurs, the associated ring or segment on the Bull’seye will indicate an alarm has occurred by changing color. Clicking on the button associated with the area in alarm accesses a Segment Window for the selected ring or segment. The Segment Window breaks the functional area into further segments, which can be used for accessing an alarm log. The default Bull’s-eye includes the following segment windows:

Note: You can enter numbers in the fields in the 3D Effect section of the window directly, or use the up and down arrow buttons next to the field to move the value in the field up or down in 1 unit increments each time you click on the button.
8. Enter a number in the Depth field to determine the depth of the Z dimension of the bars. A larger number will make the bars appear wider in the Z dimension. If 0 is entered in this field, the graph has no Z dimension, and the Inclination and Rotation fields discussed below have no effect. 9. Enter a number in the Inclination field to determine the degree of rotation in the Z dimension around the X axis. This field affects the apparent slant of the bars towards the user. Entering 0 depicts the bars as horizontal to the X plane; entering a larger number increases the slant towards the Y plane. The number entered must be between 0 and 45. 10. Enter a number in the Rotation field to determine the degree of rotation in the Z dimension around the Y axis. This field affects the extent to which the graph appears to be turned towards the user. Entering 0 depicts the graph as flat along the Y plane; entering a larger number rotates the graph in a clockwise direction towards the front of the screen. The number entered must be between 0 and 45. 11. Click on the Invert Orientation toggle button to invert the bars from horizontal to vertical. Clicking on the toggle button again will return the graph to its previous orientation. 12. Click on the Show Peak Values toggle button to show the peak values for the selected statistics on the graph. These values are shown in a contrasting color. 13. Click on the Show Axis Bounding Box toggle button to show a border around the graph on the top and right sides. Click on it again to remove the border and show only the X and Y axes at the bottom and left of the graph. The width of the bars along the Y axis (or the X axis if the Invert Orientation button is on) is determined by the Bar Cluster Width field. The number entered in this field is the percentage of the width allotted to each cluster or value represented by a bar that is taken up by the bar itself. If, for example, you enter 100%, each bar will take up 100% of the space potentially available for it, and there will be no space between the bars. They will abut each other along the Y axis. The bar cluster width must be between 10 and 100%.

Historical Statistics Reports The GeoProbe can generate on-demand reports of statistics that are recorded and stored over a period of time. Historical Statistics are configured by the GeoProbe Administrator when the GeoProbe database is configured. These statistics define the Applications, Stats Scopes, Stats Types, Stats Counters, and Network Elements to be stored for Historical Reports. The types of Historical Statistics that can be configured are the same as those available in Real-Time Statistics and Behavioral Statistics, based on installed applications. Historical Statistics are stored using a third-party database program named Oracle. Historical Reports are generated using a third-party reports application, Business Objects. Pre-defined Business Object Universes, Queries and Reports are included with the Historical Statistics Reports application. The following Universes are available on GeoProbe:

The TOC report lists the statistics tables by name and provides the corresponding number and/or name of the query. For example, the TOC report identifies Link Level 2 Statistics as Table # 2 (see Figure 6.34). This means that data from the Link Level 2 Statistics table in the Core SS7 Statistics package can be retrieved by executing the query named CORE7_02.

7. The Start Date is the date for which you want to retrieve the statistical data (the date the data was collected). Enter the Start Date in an MM/DD/YY format, for example, 10/23/00. Entering a dash (-) defaults to the current date. 8. The Start Time is the time on the Start Date at which you want to start retrieving statistical data. Enter the Start Time in a 24 hour HH:MM format, for example, 14:30. Entering a 0 defaults to 12:00 a.m. The Duration is the length of time for which you want statistical data. Enter the duration in hours. 9. The fourth field in the dialog box will vary depending on the type of statistics you are querying. You are querying Link Level 2 Statistics, so it will read Link(s). You can enter the name of the SS7 element (s) directly, but it has to be exact. It is better to click on the Values button to bring up a list of all possible elements.

Remote Monitoring Package The Remote Monitoring Application (ReMON) allows users to capture signal unit traffic from any combination of links, linksets or monitored nodes in the SS7 network. Users can filter signal unit data capture based on combinations of SS7 parameter contents. Once data is captured, it can be saved to a file either locally or at the SpIprobe and recalled later. The Surveillance Menu from Network Status includes ReMON, Recall Linkset and Recall Captured Data. Three SpImain icons are also available for working with ReMON.

ReMON Preferences Peferences are user-defined settings that affect how to display and work with messages in the ReMON Capture Window. Several icons are available for working with ReMON preferences. The different preference options are: Note: Each user must use a unique preference file to avoid conflicts with searches, filters, views, etc.
Filter
Search
View
Miscellaneous
Columns
The Filter, Search and View Windows have exactly the same parameters. The only difference is in the way each of the three preferences is used. Once one of these three preferences is defined, it is not applied until it is turned on using the appropriate icon or by clicking on the appropriate action in the Action Menu. The Miscellaneous, Columns, and Set Aging preferences take affect as soon as they are set.
7 - 12
In order to use the Filter preferences, the filter must be applied before capturing begins. The filter option cannot be used on saved data. Once the filter is turned on and capturing is started, ReMON will capture only messages that pass through the filter.
Search can be used at any time—during capture or when capture is stopped. Users can search current or saved data. Once a user clicks the Search Up icon or the Search Down icon, the application searches for captured messages that fit the criteria defined in the Search Preferences. The application highlights the first message that satisfies the requirements. To find the next instance, click the search icon again.

Messages can be tagged for later reference, and users can search the ReMON session for tagged messages. Users have to select different search icons to search for tagged messages. The Search Tag icons can be used on a current ReMON session or on post-capture data.
•
Users can search for a specific phone number with Address Search. The Address Search icon can be used on a current ReMON session or on post-capture data.
There are three View options available: •
The first View option allows users to view all messages without any requirements. All messages being captured or in a saved captured session are available to view.
•
When the second View option is selected, the View preferences set in the parameter window are applied. ReMON will continue to capture all messages (or messages based on the filter if it is turned on), but users will only be able to see messages that meet the view requirements. Once the view is off, all messages will display again.
•
The third View option only displays those messages that are tagged. Users can use this View option on current ReMON data or on a saved session.
Miscellaneous preferences are settings that affect the display of messages. Users can change the color of the messages, control the scroll rate, and automatically begin scrolling as soon as the ReMON Window opens.
The Columns preference determines the type of information displayed in the ReMON Window. All data is being captured, however users can choose to display only certain messages in the current window.

User Call Trace The User Call Trace Application (UCT) provides real-time call or transaction tracking capability. Calls or transactions can be traced throughout the SS7 network. Call Tracing allows all stages of a call or transaction to be displayed as they occur. Call and Transaction records can be expanded, and all messages pertaining to each record can be viewed in detail. UCT can be used for troubleshooting call completion problems, database lookup problems, and other circuit or transaction related problems. The Surveillance Menu from the Network Status Mode Includes Call Trace, Recall Configuration, and Recall Captured Trace options. SpImain icons are also available for working with the Call Trace application.

4. To further localize your call trace, right click in the Pointcodes box to open the Pointcode Selection List and select the pointcode(s) you wish to monitor. By selecting pointcodes, you can filter your call trace session to only capture calls that originate and/or terminate at that pointcode. Note: Since all pointcodes are related to a signalling group, once you add a pointcode to the Pointcodes field, the signalling groups associated with that pointcode are selected.
Figure 7.44 - Pointcode Definition List
5. From the Call Trace Configuration Window, click in the Type field to specify whether calls are traced by origin, destination, both, or any. 6. Enter the phone number or numbers you want to monitor in the Called and/or Calling fields. The numbers do not have to be the same length. For example, you can enter 214* in the Calling field and 5467898765 in the Called field. GeoProbe will monitor phone numbers up to 24 digits in length. However, depending on the Call Trace type selected, you can only enter a specific number of phone numbers per Call Trace session. If you want to trace selected calls to the specified pointcode(s), GeoProbe allows you to enter a wildcard (* or ?). The asterisk is a multi-digit wildcard that you can use in conjunction with a partial phone number, e.g., (214*). The question mark is a single-position wildcard that you can use with a phone number, e.g., (21?4859000).

Entering phone numbers in the Calling and Called boxes is a logical AND condition within that row. Then the Call Trace feature will only trace the number to AND the number from the selected pointcode(s).
Note: If you leave the Called and Calling fields blank, the Call Trace application will monitor all calls specific to the signalling group or pointcode selected.
Note: The OK command button closes the Configuration Window when the Call Trace Window opens. The Apply command button leaves the Configuration Window open while Call Trace is running.
Entering phone numbers in either the Calling or Called boxes below the previous number is a logical OR condition to all other rows. Call Trace feature can then trace for the numbers on the first line up through the fourth line. 7. Click the OK or Apply command buttons to start collecting messages. The Call Trace Window displays.

SUDStore and Failed Call/Transaction The SUDstore application allows Signal Units to be stored on disk at the SpIprobe. The Failed Call/Transaction application is identical to SUDStore, but only Failed Call/Transaction information is stored on a SUDStore disk that is dedicated to the Failed Calls application. The SUDStore and Failed Call applications are designed for storing Signal Units for later viewing. These applications work similar to real-time User Call Trace, but data is retrieved and viewed after it is stored rather than in real-time. The length of time and number of call records each disk can store is network and implementation dependent. Traffic, traffic types, and the number of pointcodes assigned to a profile all impact how much data can be stored on disks. SUDStore Profiles are configured by the GeoProbe Administrator. Failed Call Profiles are automatically configured if the application is installed. The conditions for defining a call or transaction as failed are defined by the GeoProbe Administrator. This course discusses the procedures for recalling and viewing SUDStore and Failed Call information. Since the procedures for recalling SUDS or Failed Calls are identical, they are discussed together. For additional information on configuration of SUDStore and Failed Calls, refer to the SpIstation Applications Guide or the GeoProbe Administrator training course.

The Pointcodes button displays a list of available pointcodes. The Type button below the Pointcodes field can be used for specifying if selected pointcodes must be either the Originating pointcode, the Terminating pointcode, either the Originating or Terminating (Any), or if two of the assigned pointcodes must be included in the same message as the Originating and Terminating pointcodes (Signalling Relation).
Digits can be assigned for Dialed numbers, Destination numbers, MINs (Mobile Identification Numbers), or other digit types depending on the Recall type. If more than one digit entry appears in each horizontal row, each digit entry must be contained within the same call. If Multiple digit entries are added below each other, digits need only match field(s) for one row to be included in the Recall. An asterisk (*) can be used as a wildcard for multiple digits, and a question mark (?) can be used as a wildcard for a single digit.
Applications allow the assignment of application-specific Time-outs and other parameters, such as Transaction or Call failure.

Mass Call Onset Package The Mass Call application detects and reports sudden high call volume to specific destination numbers in the form of alarms. Mass Call Events can be monitored in real-time using the Mass Call Status feature. An example of a Mass Call Event might be a radio contest, where people must call a certain number within a few minutes to win a prize. Suddenly, many calls are placed to the same destination phone number. The Mass Call Event Status Window would display originating and terminating information, and the number of Mass Call event counts for each origination pointcode that exceeds the Mass Call onset threshold. Mass Call profiles are configured by the GeoProbe Administrator. This course discusses how to display Mass Call Status information.

Signaling Points There are three kinds of signaling points (SP’s) in the SS7 network SSP (Service Switching Point) STP (Signal Transfer Point) SCP (Service Control Point)
(Triangle can also be used)
There are also hybrid nodes: Combined STP/SSP, SSP/SCP, STP/SCP Each SP in the SS7 network is uniquely identified by a numeric point code. Point codes are carried in messages to identify the source and destination. Each SP uses a routing table to select the appropriate path for each message.
Service Switching Point (SSP)
Switches connected through the SS7 network. SSPs serve as connecting points for input devices (phones, etc..). SSPs generate SS7 and network management messages for call control and SCP queries.

Appendix A SS7 Overview
Signal Units Information originating from a User Part (MSU’s) or from MTP2 (FISU’s & LSSU’s) is sent over a link by means of a signal unit (SU). Three types of SUs. Fill-in Signal Unit (FISU) Link Status Signal Unit (LSSU) Message Signal Unit (MSU) No Messages on a link is an immediate indication of link failure.
Common Parameters in Signal Units Flag (01111110) SU delimitation SU alignment Any time five 1s appear in a SU (other than a flag), bit stuffing is used (prior to transmission). Flag
