7 Chapter 1 System Description Overview This manual covers the General DataComm TEAM 7000 Unix Application for HP OpenView. You should be familiar with HP OpenView and with T1 digital transmission products in order to use this manual effectively. The TEAM 7000 Unix Application is actually a collection of integrated applications for the HP OpenView Network Management Platform. The applications use the Simple Network Management Protocol (SNMP) to manage GDC UAS 7000 cards TEAM 7000 applications let you: Configure UAS 7000 cards. Monitor the operation of the cards through an alarm display and through a Front Panel display that shows LED indicators as they appear on the front panel of the physical unit. Diagnose suspected problems using local and remote loops (with or without Self Test) and end-to-end Self Test. UAS 7000 System Components UAS 7000 hardware consists of three types of components: Network Interface Unit (NIU) Drop Side Interface Unit (DIU) SpectraComm Manager (SCM) Network Interface Unit (NIU) A NIU 7002 supports a single E1 line and a NIU 7001 supports a single T1 line. These units each occupy a single slot in the shelf (or enclosure) in either a single or dual shelf arrangement. The E1 interface supports MultiFrame with and without CRC, and HDB3 or optional AMI line coding. The T1 interface supports SuperFrame or Extended SuperFrame and B8ZS with optional AMI line coding.

8 1-2 TEAM 7000 Applications For the 7002, you can configure the NIUs (Network Interface Unit) as either NIU or a DIU (Dropside Interface Unit). The NIU, however, is primarily used as the network interface between SpectraComm/UAS shelf backplane. Other assets: Provides interface to T1/E1 or Fractional T1/E1 services. Has short haul (Central Office) or long haul (CPE) interface. May be mixed or matched with other GDC UAS Network Managed Data Sets. Is Network Managed through SCM SNMP interface. Contains up to 31 cards in a SCM managed shelf. Drop Side Interface Unit (DIU) The DIU (Drop-Side Interface Unit) 7616 interfaces between the 2B1Q network and the shelf backplane, providing up to three metallic loops. It consists of three two-wire transmission units using 2B1Q (ISDN Basic Rate) for its line coding scheme. It supports up to six 64 kbps or three 128 kbps services. One unit occupies a single slot in the shelf (or enclosure) in either a single or dual shelf arrangement. Specific attributes of this unit are: ITU I.430, ISDN Basic Rate, B1, and B2 loopback requirements per ITU I.601 Controllable software Six 64 kbps or three 128 kbps channels Front panel LED status of loops Independent self-test pattern generators SNMP originated diagnostics SpectraComm Manager (SCM) SpectraComm Manager (SCM) acts as the SNMP agent through which TEAM management applications communicate with UAS 7000 components. All management communications are directed to the SCM card Internet Protocol (IP) address. The SCM card relays commands and responses between management applications and hardware components, using a slot addressing scheme to communicate over the SpectraComm shelf backplane with the other UAS 7000 components. The SCM is transparent to the applications, which operate as though they were communicating directly with the hardware units. The SCM card is managed by the TEAM core application, which is also responsible for the Discovery and Mapping functions by which HP OpenView keeps track of the devices being managed. TEAM 7000 Applications The applications that make up the TEAM 7000 manager are grouped on menus under the headings Performance, Configuration, Fault, and Misc (Miscellaneous). Menus for the applications are available in two ways: By way of the menu bar of the HPOV Map window when an UAS 7000 is selected in the window, or By way of the Select button on the UAS 7000 Front Panel display. UAS 7000 Front Panel displays current status information on the card by displaying the states of the LED indicators on the front panel of the unit; and provides Select button menus where you can invoke all other functions of the TEAM 7000 manager. You can launch the Front Panel display from the HPOV Map window by means of the Front Panel selection in the Performance menu or by double- clicking on the shelf icon of the unit that you need to work with.

9 TEAM 7000 Applications 1-3 The following TEAM 7000 applications appear on the Map window and Select button menus: Performance: Administer: Alarms furnishes detailed information about alarm state changes. Front Panel launches the Front Panel display (selection appears only on Map window menu). Reports displays statistial reports. Current Interval Reports displays current 15-minutes of statistical information. Configuration lets you configure UAS 7000 cards. Maintenance allows you to set device specific attributes that are not set as configuration options. Fault enables you to run diagnostic tests on UAS 7000 cards. Misc - Contains information screen. The Misc menu in the Map window menu bar offers you a selection that does not appear in the front panel Select button menu: Front Panel Poll Rate lets you set a default polling interval to be in effect each time the front panel display is opened.

11 Chapter 2 Team Overview This chapter covers the design of the HPOV SNMP Manager for the Universal Access System (UAS) 7616 product. Graphical User Interface (GUI) windows are part of the description. The UAS manager applications are built on the HP OpenView network management platform. HP Open View provides the framework for the user interface application and the SNMP protocol for the communications framework Communications UAS uses Simple Network Management Protocol (SNMP) to carry out configuration, maintenance, status, and other functions on the SCM and 7616 cards. The IP (Internet Protocol) addressable SCM is an SNMP agent that proxies requests to the other cards in the SpectraComm Shelf. Alarms from the devices are sent to the HP OpenView Manager via SNMP Traps. The Manager furnishes the protocol stack for the SNMP Communications User Interface The Graphical User Interface for the UAS 7616 Management consists of several applications that are integrated to run under HP OpenView. The applications are summarized here: Front Panel Configuration Alarms Reports Current Interval Reports Diagnostics Maintenance Information The following are GUI screens for the UAS 7616 which are integrated into HP OpenView. The application windows presented deal specifically with 7616 family product. The Graphical Shelf and SCM applications are handled as core functionality across the SpectraComm products and are not presented in this manual.

12 User Interface Front Panel, 7616 Application The front panel status application gives you an image (See Figure 2-1) of the face plate of a shelf card. This application is started from the Graphical Shelf Application by selecting a particular shelf card icon and then selecting Performance->Front Panel, or by double clicking on a shelf card icon. The front panel contains LED images animated to reflect actual card status. This application offers you a summary of the real-time events that the unit is undergoing as well as a convenient launching point for all the major applications related to the product. Figure Front Panel Status Screen The GDC icon executes an information screen about the application. Table 2-1 defines illuminated LEDs for the 7616 Front Panel.

37 Chapter 3 Team Overview This chapter covers the design of the HPOV SNMP Manager for the Universal Access System (UAS) 7001 product. Graphical User Interface (GUI) windows are part of the of the description. The UAS manager applications are built on the HP OpenView network management platform. HP Open View provides the framework for the user interface application and the SNMP protocol for the communications framework. Communications for the 7001 UAS uses Simple Network Management Protocol (SNMP) to carry out configuration, maintenance, status, and other functions on the SCM and 7001 cards. The IP (Internet Protocol) addressable SCM is an SNMP agent that proxies requests to the other cards in the SpectraComm Shelf. Alarms from the devices are sent to the HP OpenView Manager via SNMP Traps. The Manager furnishes the protocol stack for the SNMP Communications. User Interface for the 7001 The Graphical User Interface for the UAS 7001 Management consists of several applications that are integrated to run under HP OpenView. The applications are summarized here: Front Panel Configuration Alarms Reports Diagnostics Maintenance Information The following are GUI screens for the UAS 7001 which are integrated into HP OpenView. The application windows presented deal specifically with 7001 family product. The Graphical Shelf and SCM applications are handled as core functionality across the SpectraComm products and are not presented in this manual.

63 Chapter Shelf Configuration 7001 Shelf Configuration Overview This chapter covers the design of the 7001 Shelf Configuration Application for the Universal Access System (UAS) 7001 and 7616 products. Graphical User Interface (GUI) windows are part of the description. The UAS manager applications are built on the HP OpenView network management platform. HP Open View provides the framework for the user interface application and the SNMP protocol for the communications framework. Information contained here relates to the 7001 shelf configuration support only. The System Shelf configuration application configures the T1 time slots allocation, defines circuit names and sets administrative status for the 7001 and 7616 units. Communications for the 7001 Shelf Configuration UAS uses Simple Network Management Protocol (SNMP) to carry out configuration, status, and other functions on the SCM, 7001, and 7616 cards. The IP (Internet Protocol) addressable SCM is an SNMP agent that proxies requests to the other cards in the SpectraComm Shelf. The Manager furnishes the protocol stack for the SNMP Communications. User Interface for the 7001 Shelf Configuration The Graphical User Interface for the 7001 Shelf Configuration consists of several applications that are integrated to run under HP OpenView. The applications are summarized here: 7001 T1 System Configuration Status 7001 Shelf Timing 7001 Highway Assignment 7616 Time Slot Assignment T1 Time Slot Status The following are GUI screens for the 7001 Shelf Configuration which are integrated into HP OpenView. The application windows presented deal specifically with 7001 and 7616 products. The Graphical Shelf and SCM applications are handled as core functionality across the SpectraComm products and are not presented in this manual.

71 Chapter 5 Team Overview This chapter covers the design of the HPOV SNMP Manager for the Universal Access System (UAS) 7002 product. Graphical User Interface (GUI) windows are part of the description. The UAS manager applications are built on the HP OpenView network management platform. HP Open View provides the framework for the user interface application and the SNMP protocol for the communications framework. Communications for the 7002 UAS uses Simple Network Management Protocol (SNMP) to carry out configuration, maintenance, status, and other functions on the SCM and 7002 cards. The IP (Internet Protocol) addressable SCM is an SNMP agent that proxies requests to the other cards in the SpectraComm Shelf. Alarms from the devices are sent to the HP OpenView Manager via SNMP Traps. The Manager furnishes the protocol stack for the SNMP Communications. User Interface for the 7002 The Graphical User Interface for the UAS 7002 Management consists of several applications that are integrated to run under HP OpenView. The applications are summarized here: Front Panel Configuration Alarms Reports Diagnostics Maintenance Information The following are GUI screens for the UAS 7002 which are integrated into HP OpenView.

There are 18 graph bars, each displaying bars for the TEAM 7002 application. The pairs of graph bars are identified as 0 through 16 and Avg: 0 is the number of errored seconds that have occurred so far in the current, incomplete 15- minute interval. 1 represents the most recent time period. 1 through 16 spans the recent four-hour period, divided into 15-minute intervals. Avg is the mean for the 16 values of completed intervals. The vertical axis of the bar graph displays the number of errored seconds against a selectable scale of 0 to 900, 450, or 225; click on a preferred vertical scale in Set Vertical Scale above the bar graph. The unit lets you view four hours of error reports, while non-applicable intervals are grayed-out.

85 User Interface for the The near end and far end errored seconds are shown in two different colors. The Near End Errored Seconds occurs when the local LTU detects at least one LCV or CRC error event in the signal it is receiving, where as the Far End Errored Seconds takes place when the remote unit detects at least one LCV or CRC error event in the signal it is receiving. When you are finished with this screen, click on the OK button to dismiss the window. Severely Errored Seconds (SES) Report for the Team 7002 A Severely Errored Second (SES) is defined as a one-second period having greater than or equal to 30% of errored blocks.

99 Chapter Shelf Configuration 7002 Shelf Configuration Overview This chapter covers the design of the 7002 Shelf Configuration Application for the Universal Access System (UAS) 7002 and 7616 products. Graphical User Interface (GUI) windows are part of the description. The UAS manager applications are built on the HP OpenView network management platform. HP Open View provides the framework for the user interface application and the SNMP protocol for the communications framework. Information contained here relates to the 7002 shelf configuration support only. The System Shelf configuration application configures the E1 time slots allocation, defines circuit names, and sets administrative status for the 7002 and 7616 units. Communications for the 7002 Shelf Configuration UAS uses Simple Network Management Protocol (SNMP) to carry out configuration, status, and other functions on the SCM, 7002, and 7616 cards. The IP (Internet Protocol) addressable SCM is an SNMP agent that proxies requests to the other cards in the SpectraComm Shelf. The Manager furnishes the protocol stack for the SNMP Communications. User Interface for the 7002 Shelf Configuration The Graphical User Interface for the 7002 Shelf Configuration consists of several applications that are integrated to run under HP OpenView. The applications are summarized here: 7002 System Configuration Status 7002 Shelf Timing 7002 Highway Assignment 7616 Time Slot Assignment E1 Time Slot Status The following are GUI screens for the 7002 Shelf Configuration which are integrated into HP OpenView. The application windows presented deal specifically with 7002 and 7616 products. The Graphical Shelf and SCM applications are handled as core functionality across the SpectraComm products and are not presented in this manual.

100 6-2 User Interface for the 7002 Shelf Configuration 7002 System Configuration Status Application This application is started from the Team Universe submap by selecting the desired shelf icon and then selecting Configuration->7002 Shelf Configuration (See Figure 6-1). System configuration consists of assigning backplane highway(s) to a unit, mapping the time slots of the highways to the E1, and setting Reference Timing and System Timing. The channels of the 7616 can be assigned to time slots of any two of the four highways. A Network Side 7002 can be assigned to only one highway. Never available for customer payload are Time Slots 0 and 16. The main menu bar has File, Navigate, and Help selections. Each of these are described below. Figure 6-1 TEAM 7002 Shelf or System Configuration Status Screen Table 6-1 File Menu, 7002 Shelf Configuration File Menu File -> Refresh Read and update all data on all screens of this application. File -> Exit Causes the application to terminate, with outstanding edits discarded first. NOTE: It is critical to this application to perform a Refresh if any 7002 or 7616 Unit Configuration is changed in this shelf. Refresh provides current configuration information of the shelf units to the 7002 Shelf Configuration application for proper updating. Otherwise, misleading information could be viewed and misinterpreted.

104 6-6 User Interface for the 7002 Shelf Configuration 7616 Time Slot Assignment This screen is presented when Navigate->7616 Time Slot Assignment is selected. The screen assigns 7616 loops to time slots within highways. Note that since Network Side 7002s are assigned to a single highway, Time Slots 0 and 16 of that highway are unavailable (See Figure 6-4). You can assign 7616 loops to two of the four highways. You can use the highway selection boxes to choose your highway. Highway choices are N/A (not assigned), or 1-4. For each loop, boxes select a time slot for a specific highway. Options are N/A (not assigned), or 1-31 (not selectable is 16). Figure Time Slot Assignment Screen Table Time Slot Assignment Menu Name Shelf Name (read-only) Selections For Highways 1 through 4 Selected Unit Lists 7616s previously configured as Drop Side.

Highway Two of the four highways: 1st Highway Left controls column 2nd Highway Right controls column Loops 1A through 3B Selects time slot assigned to the loop on one highway, which leaves the other highway loop slot not selectable. Note that if Channel A of a loop is configured for 128 kbps, then Channel B controls are grayed-out. Moreover, the range of time slots is limited to 30 for each channel and the same name is used for both Channels A and B. It is mandatory that Channel B with128-kbps has a one time-slot higher than that for Channel A. This keeps both channels in consecutive sequence. While Channel B controls are grayed-out and Channel B is not in sequence with Channel A, click on Save and the application automatically checks and allocates consecutive time slots. The application accomplishes this by allocating Channel B with a time slot one greater than that of Channel A. Name An optional 16-character name can be assigned to each channel.

107 Chapter 7 610, 612, , 612, and 621 Overview This chapter covers the design of the HPOV SNMP Manager for the Universal Access System (UAS) 600 products, specifically units: 610, 612, and 621. Graphical User Interface (GUI) windows are part of the description. The UAS manager applications are built on the HP OpenView network management platform. HP Open View provides the framework for the user interface application and the SNMP protocol for the communications framework. These units are remote units linked to the UAS 7616 in the SpectraComm Shelf. 610, 612, and 621 Communications UAS uses Simple Network Management Protocol (SNMP) to carry out configuration, maintenance, status, and other functions on the SCM and 610, 612, and 621 cards. The IP (Internet Protocol) addressable SCM is an SNMP agent that proxies requests to the other cards in the SpectraComm Shelf. Alarms from the devices are sent to the HP OpenView Manager via SNMP Traps. The Manager furnishes the protocol stack for the SNMP Communications. 610, 612, and 621 User Interface The Graphical User Interface for the UAS 610, 612, and 621 (600 Management) consists of several applications that are integrated to run under HP OpenView. The applications are summarized here: Front Panel Configuration Alarms Reports Diagnostics Maintenance Information The following are GUI screens for the UAS 610, 612, and 621 which are integrated into HP OpenView. The application windows presented deal specifically with the 600 family products. The Graphical Shelf and SCM applications are handled as core functionality across the SpectraComm products and are not presented in this manual.

108 , 612, and 621 User Interface Front Panels, 610, 612, and 621 Applications The front panel status application lets you see the image of the face plate of the card for the front panel of the 610, 612, or 621 unit. You begin this application by double clicking on the 7616 card slot icon on the Graphical Shelf Application and immediately shown to you is the Element Submap. Arrayed in this Element Submap is a 7616 unit icon, shown connected to as many as three 600 unit icons. Figure 7-1 is an example of an Element Submap. You have two ways to access a specific 600 front panel: either (1) single click on one of the icons of the 600 remote units and then choose Performance->Front Panel; or (2) double click on one of the 600 remote unit icons in the Element Submap. The front panel image (See Figure 7-2) represents LED images animated to reflect actual card status. Offering you a summary of the real-time events that the unit is undergoing, this application gives you a convenient launching point for all the other major applications related to these 600 series products.

Examples are: time, not responding, etc. 610, 612, and 621 Configuration The Graphical User Interface for the Configuration Application incorporates features for optioning the 610, 612, and 621 products. With the Configuration Application, you have access to unit level parameters via the SNMP queries when Windows are displayed or refreshed. Through SNMP set commands, modifications are applied to the unit. The configuration application has templates for copying the same configurations to other units. Configuration templates are stored permanently and are easily accessed. You can initiate the Configuration Application for each 600 unit on the open map. The 610, 612, and 621 configurations are launched from the HPOV Element Submap by first selecting a particular 600 remote unit, then choosing Configuration->Configure from the Menu bar or from the Front Panel application Select button menu. One main window and a set of transient windows, offering unit optioning, make up this application. Included are the 600s configuration (main widow), Unit Configuration Options, Alarms Reported, and All Screens. Configuration - Main Window The main window is comprised of four areas. The title bar provides the product name and configuration type. The name field contains the Shelf name, slot number and symbol label. The menu bar provides file operations, navigation through subordinate screens and help. The main body of the window is composed of administrative read-only fields. The status message area at the bottom of the screen provides insight into the state of the application (See Figure 7-3). Note that the three 600s main window configuration screens are all very similar to each other, except that the 612 has two DTE card types, DTE1 and DTE2.

The statistics displayed for the 610, 612, and 621 products in the Error Reports summary window cover the Current 24 Hours. For the 24-hour period (Figure 7-7), shown along the vertical axis in intervals of seconds are errors that have occurred for each of three error events: ES (Errored Seconds), SES (Severely Errored Seconds), and UAS (Unavailable Seconds). There are also three different vertical scales. Select one of them by clicking on one of the items in Set Vertical Scale. Error Reports Window Menus (610, 612, and 621) The Error Reports window has File and Navigate menus in its menu bar. The File menu consists of Refresh and Exit selections. The Refresh selection reads the statistics from the unit and updates the display to reflect changes that have occurred since the window was opened or since the last Refresh. The Exit selection dismisses the Error Reports window. The Navigate menu contains four detailed Error Report displays: Errored Seconds (Graph)... Severely Errored Seconds (Graph)... Unavailable Seconds (Graph)... Errors (Text)... The first three are graphic screens detailing information about errors collected at 15-minute intervals during the current 24-hour period; the last one lists the errors as text. Errored Seconds (ES) An Errored Second (ES) is defined as a second with at least one CRC error event. Figure 7-8 shows the 610 Errored Seconds (ES) screen. In Set Vertical Scale you have three vertical scales to choose from. The screen shows also numeric display of error totals for the current 24 hours. This screen also graphs the number of errored seconds that have taken place in the current 24 hours. Select 4 Hour Period menu allows the users to choose a different 4-hour period in the current 24-hour interval.

118 , 612, and 621 User Interface Figure 7-8 Errored Seconds (ES) Window for the TEAM 610, 612, or 621 Time intervals are the horizontal axis of the bar graph display. There are 18 graph bars. The graph bars are identified as 0 through 16 and Avg: 0 is the number of errored seconds that have occurred so far in the current, incomplete 15- minute interval. 1 through 16 spans the four-hour period selected, divided into 15-minute intervals. Avg is the mean for the 16 values of completed intervals. The vertical axis of the bar graph displays the number of errored seconds against a selectable scale of 0 to 900, 450, or 225; click on a preferred vertical scale in Set Vertical Scale above the bar graph. The unit lets you view twenty four hours of error reports, while non-applicable intervals are grayed-out. If the unit has not completed 24 hours of operation, then the unavailable periods and intervals are grayed-out. In Figure 7-8, you can see from this example, that all intervals, except 0, are grayedout. When you are finished with this screen, click on the OK button to dismiss the window.

119 610, 612, and 621 User Interface 7-13 Severely Errored Seconds (SES) Display Screen for the 610, 612, and 621 A Severely Errored Second (SES) is defined as a second with 7 or more CRC error events, or one or more Out of Frames. Figure 7-9 shows the 610 Severely Errored Seconds (SES) screen since the 610 unit is quite similar to the 612 and 621. In Set Vertical Scale you have three vertical scales to choose from. The screen also shows numeric display of error totals for the current 24-hour interval. This screen also graphs the number of severely errored seconds that have taken place in the last 24 hours, taking one 4-hour period at a time. Figure 7-9 Severely Errored Seconds (SES) Window for the TEAM 610, 612, or 621

120 , 612, and 621 User Interface Time intervals are the horizontal axis of the bar graph display. There are 18 graph bars. The graph bars are identified as 0 through 16 and Avg: 0 is the number of severely errored seconds that have occurred so far in the current, incomplete 15-minute interval. 1 through 16 spans the four-hour period selected, divided into 15-minute intervals. Avg is the mean for the 16 values of completed intervals. The vertical axis of the bar graph displays the number of severely errored seconds against a selectable scale of 0 to 900, 450, or 225; click on a preferred vertical scale in Set Vertical Scale above the bar graph. The unit lets you view one four-hour period at a time taken out of a 24-hour interval of error reports using Select 4 Hour Period. The non-applicable intervals are grayed-out. If the unit has not completed 24 hours of operation, then the unavailable time periods and intervals are grayed-out. In Figure 7-9, you can see from this example, that all intervals, except 0, are grayedout. When you are finished with this screen, click on the OK button to dismiss the window.

121 610, 612, and 621 User Interface 7-15 Unavailable Seconds (UAS) Display Screen for the 610, 612, and 621 Unavailable Seconds (UAS) is defined as a count of one-second intervals when service is not available. Service-not-available means 10 or more consecutive SESs. Figure 7-10 shows the Unavailable Seconds (UAS) screen for the 610 product, which is like the 612 and 621. In Set Vertical Scale you have three vertical scales to choose from. The screen shows also numeric displays for current 24-hour period error totals. This screen graphically shows the number of unavailable seconds that have taken place in the last 24 hours, taking one 4-hour period at a time. Figure 7-10 Unavailable Seconds Reports (UAS) Window for the TEAM 610, 612, or 621 Time intervals are the horizontal axis of the bar graph display. There are 18 pairs of graph bars. The graph bars are identified as 0 through 16 and Avg: 0 is the number of unavailable seconds that have occurred so far in the current, incomplete 15-minute interval. 1 through 16 spans the four-hour period selected, divided into 15-minute intervals. Avg averages the 16 values for completed intervals. The vertical axis of the bar graph displays the number of unavailable seconds against a selectable scale of 0 to 900, 450, or 225; click on a preferred vertical scale in Set Vertical Scale above the bar graph.

122 , 612, and 621 User Interface If the unit has not completed 24 hours of operation, then the unavailable 4-hour time periods and intervals are grayed-out. In Figure 7-10, we see all categories, except 0, are grayed-out. Figure 7-10 exemplifies a vertical bar graph, indicating about 240 unavailable seconds. When you are finished with this screen, click on the OK button to dismiss the window. Errors (Text) for the 610, 612, and 621 The Error Events display screen is the text version of the Error Reports graphic representations. It tabulates some data on the three types of error events that have occurred. See Figure 7-11 for the 610, which is like the 612 or 621. Figure 7-11 Error Events Window for the 610, 612, or 621 The screen displays Total Error Events, showing total events over a 24-hour period: Current 24 Hours (without Current Interval) The display headed Current Error Events: Current 15 Minute Interval shows the error events accumulated thus far in the uncompleted current interval. For the 15-minute boundary, the accumulation is transferred to the Current 24 Hours count and a new current interval begins. The screen displays the number of valid 15-minute intervals during the current 24 hours and lists the errors reported in each 15-minute interval. Click on the OK button to dismiss the window when you are finished with it. Current 15-Minute Interval Error Report for the 610, 612, and 621 The Current 15-Minute Interval Error Report for the 610, 612, and 621 is used to display the errors that have occurred during the current 15-minute, incomplete interval. This report is accessed from the HPOV Map Performance-> Current Interval Reports or from the front panel, which fetches and displays data from the 610, 612, and 621 cards. With this window, you have two vertical scales. The left scale pertains to the readings for the ES, SES, and UAS, where the bar graph displays the number of errored seconds against a selectable scale of 0 to 900, 450, or 225. Click
