Manual Conventions

Preface

Throughout this manual the following typographic, symbolic, and terminology conventions apply:

Typographic Conventions

H Bold terms are found in procedures and denote interface items that you need

to select in order to cause an event to occur. For instance, to configure default directories the procedure would read as follows:

Select Directories from the Options menu.

In this example, even though the Options menu is an interface element, the Directories selection is the element that displays the needed dialog box (causes an event to occur) and is the only bold term. When interface items are referred to outside of procedures, the terms are not boldface.

MTS300 System Overview

The MTS300 MPEG Test System is a component of the Video Quality of Service (VQoS) products offered by Tektronix. The MTS300 system (see Figure 1--1) is a high-performance MPEG protocol diagnostic and analysis tool that provides you with innovative solutions to meet the challenges of designing, verifying, and characterizing products and systems using MPEG-2 technology.

The MTS300 system offers powerful acquisition and computational capabilities for analyzing designs based on MPEG, DVB, ATSC, and ISDB standards. These flexible and expandable capabilities include real-time monitoring, data rate analysis, and Tektronix-exclusive timing analysis to help diagnose the most challenging problems and characterize real-time performance.

NOTE. Refer to the MPEG-2, DVB, ATSC, and ISDB-S/ARIB standards for detailed information about the syntax and semantics of each system.

The deferred-time (off-line) analysis provided by the MTS300 system helps you fully verify compliance to standards and diagnose problems in complex transport streams. Easy-to-use transport stream capture, playout, and on-line storage lets you build extensive suites of test streams, and then use these streams to exercise your designs. Additional stream editing capability, with error and jitter injection and real--time multiplexing, gives you the ability to create and playout test sequences that fully stress and characterize design parameters.

Primary Applications

Each test system can monitor up to two transport stream inputs simultaneously and accepts inputs in the following electrical formats:

H ASI/M2S (the test system automatically detects the format)

H SPI (LVDS parallel); available when you order the MTS3FLV upgrade

H DHEI (GI Digicipher II): available when you order the MTS3FDE upgrade

H SSI (SMPTE 310M); available when you order the MTS3FSS upgrade

The MTS300 system was designed for the following applications:

H Evaluation and verification of MPEG, DVB, ATSC and ISDB designs

Design and verification of digital-video set-top boxes (STBs)

H Stress and characterization of electrical circuits and ICs developed for

products using MPEG-2 compressed digital-video technology

System Architecture

The MTS300 system uses a client/server architecture consisting of a Server Manager, two Analysis Server pairs (each pair consists of one MPEG analysis server and one TMCC analysis server), and the following client applications: Master Client, Expert Client, Configuration Client, Stream Recorder, Stream Player, TMCC Expert Client, and TMCC Configuration Client

Combined, these client/server modules enable you to monitor multiple transport stream inputs simultaneously, perform in-depth analyses on one transport stream input, and to configure the monitoring and reporting parameters. The system is tightly integrated, making it easy to use for experts and non-experts alike.

Server Manager. The Server Manager is the process that makes the results of the Analysis Servers and other real-time application servers available to Master Clients. The Server Manager starts automatically when you start the transport monitor. Only one Server Manager can run on a test system.

The Server Manager process interacts with the following entities:

H The Analysis Server sends analysis results (called traps)totheServer

Manager.

H The Stream Player, Stream Recorder, and optional OpenMux (MTS300,

Option OM) servers send state traps to the Server Manager.

1- 4

H The Master Client displays the data collected by the Server Manager .

MTS300 MPEG Test System Real-Time Analysis User Manual

Getting Started

Analysis Servers. The Analysis Server is the process that actually analyzes transport stream inputs. Each Analysis Server process consists of one MPEG Analysis Server and one TMCC Analysis Server. Each MTS300 system can support up to two Analysis Server processes of each type simultaneously.

The Analysis Server processes interact with the following entities:

H The Server Manager collects the Analysis Server results (called traps).

H The Expert Client displays the results of the MPEG Analysis Server directly.

Likewise, the TMCC Expert Client displays the results of the TMCC Analysis Server .

H The Configuration Client sets the monitoring and analysis parameters for

each MPEG Analysis Server process operating on the inputs to the MTS300 system. Likewise, the TMCC Configuration Client sets the monitoring and analysis parameters for each TMCC Analysis Server process.

Master Client. The Master Client application provides an intuitive interface for controlling and monitoring the status of the I/O ports on the MTS300 system. You can run only one Master Client on each MTS300 system. In a network environment, if a remote MTS300 system has a Master Client open, you must shut down the remote Master Client before you can connect your local Master Client to the Server Manager running on the system.

NOTE. Each MTS300 system is limited to operating two Analysis Server processes of each type at a time, and can run only one Stream Player, one Stream Recorder, and one OpenMux application at a time. In addition, the MTS300 system is limited to an aggregate data rate of 140 Mbs between all operating applications.

From the Master Client, you can perform the following tasks:

H Monitor and analyze MPEG transport streams in real time using the Expert

Client and Configuration client applications.

H Monitor and analyze single- and multi-program TMCC transport streams in

real time using the TMCC Expert Client and TMCC Configuration Client applications.

H Record and playback MPEG and TMCC transport streams using the Stream

Recorder and Stream Player applications.

H Generate multiplexed transport streams in real time using the OpenMux

application (MTS300, Option OM).

MTS300 MPEG Test System Real-Time Analysis User Manual

Getting Started

The Master Client uses three areas to display different type of information:

H The I/O Port Manager panel displays icons representing real-time application

servers and the input and output ports configured on your test system.

H The Services panel displays icons for the services (also called programs)

encoded in the transport stream you are monitoring.

H The Details panel displays icons indicating the type, status, and severity of

errors on a transport stream or service.

Expert Client. The Expert Client application allows you to analyze a single MPEG transport stream in greater detail. You will use the Expert Client as your primary tool to help troubleshoot errors in your digital transmission system.

The Expert Client characteristics are shown in the following list:

H Graphical displays that show the structure (hierarchy) of the input transport

stream and display characteristics of each component of the input stream (for example: PID and type allocation, section rate analyses, and timing analyses).

H Report views that indicate the types of errors recorded by the Analysis

Server and the characteristics of the input stream.

H Error views that show specific errors recorded for the various components

of the transport stream; for instance, PMT section rate errors and ETR290 errors.

The Expert Client can display the results of only one MPEG Analysis Server (input) at a time.

Configuration Client. The Configuration Client allows you to perform the following tasks:

H Specify to which standard you are testing: MPEG-2, DVB, ATSC, or ISDB.

H Set, remove, or modify the probes that test transport streams for valid syntax

and semantics and rates.

H Specify the way in which errors are reported in both the Expert and Master

Clients. You can configure each probe to report an error as Critical, Major, Minor, Warning, or as information only.

H Specify the types of transport stream events that are recorded using the Data

Logging function. You can also set the maximum file size and time period of each log file.

1- 6

MTS300 MPEG Test System Real-Time Analysis User Manual

Getting Started

H Stop and restart an MPEG Analysis Server running on a MTS300 system.

H Set passwords on specific inputs that prevent others from changing the

Analysis Server configuration for that input.

H Set parameters for capturing part of an input transport stream.

Stream Recorder Client. The Stream Recorder application allows you to record a transport stream onto the hard drive of the MTS300 system using a VTR-like interface. You can specify the stream format, duration, file name, and location of the recorded file.

The Stream Recorder is governed by the following MTS300 system limits:

H Only one Stream Recorder can be launched at a time on each MTS300

system.

H The Stream Recorder can only record transport stream files with data rates

between 1 Mbs and 140 Mbs onto the hard drive of the MTS300 system on which the application was launched. You cannot record remote transport stream files or use a remote Stream Recorder to record a local transport stream file.

NOTE. It is recommended that you store transport stream files on the SCSI hard drives (E: drive) of the MTS300 system. The response time of the C: drive on the MTS300 system is limited and may affect the performance of the Stream Recorder and Stream Player applications when you try to capture or play back streams with bitrates greater than 30 Mbs.

H If the SCSI hard drives (E:) are 90% or more full, it is recommended that

you use a defrag utility to defragment the SCSI drives. You can use any defrag utility that is compatible with the Microsoft Windows NT 4.0 operating system.

H The MTS300 system is limited to an aggregate data rate of 140 Mbs between

all operating applications. You may have to shut down other MTS300 applications if you need to record a transport stream with high data rates.

MTS300 MPEG Test System Real-Time Analysis User Manual

1- 7

Getting Started

Stream Player Client. The Stream Player application allows you to play back transport streams saved on the hard disk of the MTS300 system using a VTR-like interface. You can specify which portion of the transport stream to play back, the rate of the transport stream (you can also apply an external clock to set the rate), the format (ASI or M2S) of the transport stream, and the playback mode (one time or loop).

The Stream Player is governed by the following MTS300 system limits:

H Only one Stream Player can be launched at a time on each MTS300 system.

H The Stream Player can only play back transport stream files with data rates

between 1 Mbs and 140 Mbs stored on the hard drive of the MTS300 system on which the application was launched. You cannot play back remote transport stream files or use a remote Stream Player to play back a local transport stream file.

H If the SCSI hard drives (E:) are 90% or more full, it is recommended that

you use a defrag utility to defragment the SCSI drives. You can use any defrag utility that is compatible with the Microsoft Windows NT 4.0 operating system.

H The MTS300 system is limited to an aggregate data rate of 140 Mbs between

all operating applications. You may have to shut down other MTS300 applications if you need to play back a transport stream with high data rates.

TMCC Expert Client. The TMCC (Transmission and Multiplexing Configuration Control) Expert Client application allows you analyze the TMCC data of an ISDB-S/ARIB-compliant transport stream input in real time. You can also analyze an ISDB-S/ARIB-compliant transport stream file stored on your local disk.

The TMCC Expert client has the following characteristics:

H Indicates the presence of sync bytes (0x47 for TMC C basic streams and W1,

W2, or W3 sync bytes for TMCC data streams)

H Displays the syntax of TMCC data

H Displays Slot, TSID, TS Name, and Modulation mode information

H Displays information, warning, and error messages

H Indicates the presence of TMCC alarm and update flags in the transport

stream

H Displays the overall stream rate

The TMCC Expert Client displays the results of only one TMCC Analysis Server (input) at a time. You can connect more than one TMCC Expert Client to the same TMCC Analysis Server input from your own instrument, or you can connect to an Analysis Server from a remote MTS300 system.

MTS300 MPEG Test System Real-Time Analysis User Manual

1- 9

Getting Started

TMCC Configuration Client. The TMCC (Transmission and Multiplexing Configuration Control) Configuration Client is used to configure the analyses performed by the TMCC Analysis Server. The results of the analyses are displayed in the TMCC Expert Client.

NOTE. Only one TMCC Configuration Client at a time can set parameters on a TMCC Analysis Server. If a TMCC Configuration Client is already connected to a TMCC Analysis Server, you can view the current settings, but you cannot change them.

The settings in the TMCC Configuration Client only configure the measurements made by the TMCC Analysis Server, which are displayed in the TMCC Expert Client application. The TMCC Configuration Client settings do not affect the configuration settings in the Configuration Client, which is used to configure the measurements made by the MPEG Analysis Server.

The TMCC Configuration Client has the following characteristics:

SNMP Capabilities

H Uses multiple configuration panels to group related configuration functions.

H Uses a hierarchic navigation panel to select one of the multiple configuration

panels.

H Configures the TMCC Analysis Servers to operate in either TMCC basic or

TMCC data stream modes

H Enables you to specify a transport stream ID to analyze using the MPEG-2

Analysis Server (only in the TMCC data stream mode)

The MTS300 system includes SNMP management information bases (MIB) installed at the following directory location: C:\Mib\. The Tektronix MIB is a textual description of the Analysis Server objects (functions and parameters) that can be monitored and controlled via SNMP. Refer to Appendix C: Networking for more information about the networking requirements of the MTS300 system.

The MIB files are used by the real-time analysis applications and the Stream Player, Stream Recorder, and OpenMux (MTS300, Option OM only) applications.

The MIB file pairs for each application, for example, the RTAv1.mib and RTAv2.mib files, are used for SNMPv1 and SNMPv2 systems respectively.

MPEG Operational

Monitoring

This section provides some brief overviews of MPEG monitoring and the types of transport streams monitored and analyzed by the MTS300 system.

In today’s compressed digital TV environments you can think about operational monitoring requirements in terms of layers:

H Information layer. Is the information correct and of suitable quality?

Monitoring the information layer is an extension of picture quality measurements in the compressed digital realm.

H Transmission layer. Does the signal itself conform to standards?

Monitoring the transmission layer is standard practice in all transmission systems: cable, terrestrial, and satellite.

H Protocol layer. Can the transmitted data be decoded at the destination?

Monitoring the protocol layer is a new requirement of MPEG transmission systems. The protocol layer is monitored by the Master Client.

3- 2

MTS300 MPEG Test System Real-Time Analysis User Manual

Reference

The protocol layer provides the following functionality:

H Metadata. Metadata refers to information about the transport stream that is

carried by the transport stream such as PSI and SI or PSIP tables. This information describes the multiplex and the transmission environment completely so that the IRD (integrated receiver/decoder) can decode the transport stream correctly. Metadata is specified in the appropriate MPEG, DVB, and ATSC standards.

H Timing information. Timing information is used by the IRD to decode and

present the data correctly (at the right times and in the right sequence). Timing information is carried in both the transport stream layer and the elementary stream layer.

MPEG monitoring is used to verify that the transport stream you are transmitting conforms to the appropriate MPEG-2, DVB, ATSC, and ISDB-S/ARIB standards. The following list describes operational monitoring requirements that you may have for your environment:

H Ensure that transmitted data is free of defects and can be decoded

appropriately at the destination. This monitoring task is performed by the Master client.

H Identify specific errors so you can isolate the source of errors quickly. This

analysis task is performed by the Expert Clients.

H Specify monitoring parameters for transport streams in ways that make sense

to you. This configuration task is performed by the Configuration Clients.

MPEG-2

MPEG stands for Motion Picture Experts Group. Among the standards developed by this ISO body are the set of standards describing Transport Stream System Target Decoders (T-STD) with defined behaviour when handling video, audio, or data elementary streams or when handling PSI (Program Specific Information) packets. By defining a T-STD, the output of encoders and multiplexers is implied. Consequently, the output of any valid MPEG-2 encoder or multiplexer can be used as input to another manufacturer’s decoder or multiplexer.

MPEG-2 transport streams are two layer structures: the Compression layer (for encoded audio, video, and data elementary streams) and the System layer (for timing and describing different elements of the multiplexed transport stream and the network over which it is carried).

Valid MPEG-2 transport streams require certain information that describes the content and organization of transport streams and certain characteristics of the network over which the transport stream is carried. This information is called Program Specific Information (PSI) and is carried in table structures:

H Conditional Access Table (CA T)

H Network Information Table (NIT)

H Program Association T able (PAT)

H Program Map Table (PMT)

H Transport Stream Descriptor Table (TSDT)

See the MPEG-2 standards documents for more specific information about encoding elementary streams, multiplexing transport stream elements, and these transport stream structures.

One of the strengths of the MPEG standards is that they are generic and can be adapted to different broadcast environments. Three groups, the Digital Video Broadcasters (DVB), the Advanced Television Systems Committee (ATSC), and the Association of Radio Industries and Business (ARIB) have created MPEG-2 compliant standards that are used in DVB, ATSC, and ISDB-S/ARIB markets.

DVB

DVB stands for Digital Video Broadcasting. DVB standards define MPEG-2 compatible transport streams used in DVB markets. The DVB standards define baseline systems for cable (DVB-C), terrestrial (DVB-T), and satellite (DVB-S) transmission environments.

Like the MPEG standards, the DVB standards describe both the compression layer (for encoded audio, video, and data elementary streams) and the system layer (for timing and describing different elements of the multiplexed transport stream and the network over which it is carried) of DVB transport streams.

The DVB standards define additional service information (SI) used to describe the network, transport stream, and services carried by the transport stream. This additional information is provided by the following table structures:

H Bouquet Association Table (BAT)

H Event Information Table (EIT)

H Network Information Table (NIT)

H Running Status Table (RST)

H Service Description Table (SDT)

H Time and Date Table (TDT)

H Time Offset Table (TOT)

H Discontinuity Information Table (DIT)

H Selection Information Table (SIT)

Reference

ATSC

ATSC stands for Advanced Television Systems Committee. ATSC standards were developed by the ATSC Technology Group on Distribution (T3). These standards define baseline systems for cable and terrestrial environments. ATSC transport streams are valid MPEG-2 transport streams.

Like the MPEG standards, the ATSC standards describe both the compression layer and the system layer for ATSC transport streams. The compression layer refers to the encoded audio, video, and data elementary streams; the system layer refers to timing information and descriptions of different elements of the multiplexed transport stream and the network over which it is carried.

The ATSC standards define additional information required for ATSC environments. This information is carried in the following program and system information protocol (PSIP) table structures:

H Event Information Table

H Extended Text Table

H Master Guide Table

H System Time Table

H Rating Region Table

H Virtual Channel Table

See the ATSC standards documents for more specific information about these transport stream structures. One of the ATSC standard documents (ATSC Document A/58) describes how to ensure that valid ATSC transport streams are also valid DVB transport streams (conforming to DVB standards).

ARIB/ISDB Overview

ARIB stands for the Association of Radio Industries and Business. ARIB standards define elements (carried in table structures) for managing ARIB-compliant transport streams (these are the ARIB structures analyzed by the MTS300 system):

H Broadcaster Information Table

H Download Control Table

H Download Table

H Software Download Trigger Table

ISDB-S/ARIB transport streams are MPEG-2 compliant streams that conform to the ITU-R standard for ISDB-S (Integrated Service Digital Broadcasting, Satellite) multiplexing. An ISDB stream uses TMCC (Transmission and Multiplexing Configuration Control) data multiplexed in the first eight bytes of the 16 Reed-Solomon bytes of 204 byte MPEG-2 transport streams. TMCC information is used to manage the modulation parameters of the transponders in digital broadcast environments that include multiple broadcasters and types of services with different transmission requirements.

Client-Server Overview

This section briefly describes client-server software architecture and the two server modules enabled by the MTS300 system software.

Client-Server

The client-server software architectural model allows software to be developed into two or more modules:

H The server module performs CPU intensive operations, runs in the back-

ground (or remotely), and responds to requests from clients. Usually requests are due to some action you have taken.

H The client module is often a graphical user interface that allows you to

configure or display the status of the server module.

The MTS300 system uses six servers (Server Manager, MPEG Analysis Server, TMCC Analysis Server, Stream Recorder and Stream Player servers, and Real-Time Multiplexer Server) to control any of the following client applications you operating::

H Master Client

H Expert Client

H Configuration client

H Stream Recorder

H Stream Player

H TMCC Expert Client

3- 8

H TMCC Configuration Client

H OpenMux (MTS300, Option OM only)

Combined, the client and server modules enable you to monitor multiple transport stream inputs simultaneously; perform in-depth analyses of one transport stream input; configure the monitoring and reporting parameters of the monitored inputs; and to create, generate, and capture transport streams.

MTS300 MPEG Test System Real-Time Analysis User Manual

Reference

Analysis Servers

Server Manager

The Analysis Servers are the processes that perform the actual analyses on transport stream inputs. Each Analysis Server process consists of an MPEG Analysis Server and a TMCC Analysis Server. Each MTS300 system can support up to two Analysis Server processes of each type simultaneously. The Analysis Server sends analysis results to the Server Manager .

Each Analysis Server interacts with the following entities as described:

H The Master client displays the analysis results that are collected by the

Server Manager.

H The Expert clients display the results of the Analysis Servers directly.

H The Configuration clients set the monitoring and analysis parameters for

each input.

H The Server Manager collects the Analysis Server results (called traps).

The Server Manager is the process that allows the MTS300 system to be managed over a network. The Server Manager also makes the results of the Analysis Servers available to Master clients. Only one Server Manager can run on an MTS300 system.

The Server Manager process is available to or responds to the following two entities:

H The Master client, which displays the data collected by the Server Manager .

H The Analysis Server, which sends messages (or traps) to the Server Manager.

NOTE. Only one Master Client can be connected to a Server Manager at any given time.

NOTE. An individual MTS300 system is limited to operating two Analysis Servers at a time, and can launch only one Stream Player, one Stream Recorder, and one OpenMux application at a time. In addition, the MTS300 system is limited to an aggregate data rate of 140 Mbs between all operating applications.

Master Client Application Window

When you first start the Master Client application, the panels of the application workspace are empty. Before you can monitor inputs or generate a transport stream output, you must first connect the Master Client to a Server Manager and then assign the I/O ports to an Analysis Server or application. After you connect to an Analysis Server, the Master Client workspace displays the current status of the I/O ports on the MTS300 system to which you are connected.

The status displayed for each I/O port depends on which application is assigned to the I/O port. The status of a monitored program stream depends on the analyses being performed by an Analysis Server . The Analysis Server sends error messages or traps to the local Server Manager. This error information is presented using the interface elements of the Master Client.

The Address bar indicates the name or IP address of the MTS300 system running the Server Manager to which you are connected. You can enter the name or IP address directly or you can use the selection box to choose a remote machine name. The selection box is available only when the Master Client is disconnected from a Server Manager.

The selection box keeps a record of the MTS300 systems to which you have successfully connected. So, rather than entering a host name or IP address each time you connect to a remote machine, you can choose the name from the list.

You can choose to display or hide the Address bar using the View menu.

The Selection Indicator bar shows you which Master Client workspace items are currently selected. In Figure 3--1 on page 3-- 12, the Selection Indicator bar shows the name of the input (Analysis Server), and service (TSID 0) selected.

Port Manager Panel

The Port Manager panel is located at the left of the Master Client window. The Port Manager panel displays icons representing the I/O ports for the Server Manager to which you are connected. Each I/O port icon represents one input/output channel pair. You can only assign one Analysis Server or application to one I/O pair at a time.

Initially the I/O ports are represented by icons labeled Free. The Free icon shows that the server for that particular I/O port has not been assigned to an Analysis Server or application.

Before you can monitor a transport stream input or generate a stream output, you must assign the I/O port to an Analysis Server or application using the shortcut menu, which is accessed by right-clicking a Free I/O icon.

You can configure icons in the Port Manger panel to be shown as large or small icons, and to be sorted by error (multiplexes with errors are displayed before multiplexes without errors), by MTS300 system name, or by TSID.

You can resize the height and/or width of the Port Manger panel by clicking and dragging the lower or right-panel border.

When you select a Port Manager panel Analysis Server icon, the Services panel and the Details panel both change:

H The Services panel changes to show icons for the services that you are

monitoring on that input.

H The Details panel changes to show icons indicating the error type and

severity of MPEG, DVB, or ATSC transport stream level errors.

Error Icons. The error icons that overlay the input icons in the Port Manager panel are used to show the status of errors on the input:

H Red error icons indicate that transport stream, or one or more services in the

transport stream are experiencing an error.

H Orange error icons indicate that the transport stream, or one or more services

in the transport stream, recorded one or more errors, but that the error condition no longer exists.

H Yellow error icons indicate that a warning condition exists for one or more

services in the transport stream.

Services Panel

Shortcut Menus. Right-click an icon in the Port Manager panel open a shortcut menu. The selections available in the shortcut menu depend on the type of icon selected in the Port Manager panel. You will use the shortcut menus to assign I/O ports to applications and to start the Expert Client or Configuration Client for an Analysis Server. See Port Manager Panel Shortcut Menus on page 3--23 for a description of the shortcut menu commands.

The Services panel displays icons for the selected input and is located to the right of the Master Client window. You can resize the width of the Service panel by clicking and dragging the left panel border, and you can resize the height by dragging the lower panel border.

A default service icon is used to display each monitored service in the selected Multiplex. You can also assign a custom icon to each service (see Assigning a Logo to a Service Icon on page 3--33).

By selecting an Analysis Server icon in the Port Manager panel, and then double-clicking an icon in the Services panel, you can start the Expert Client. The Expert Client will be connected to the Analysis Server on the selected input. When the Expert Client is displayed, the Report view will be in the Program mode showing the error messages for the selected service.

The Services panel has three modes of display that you can select from the shortcut menu:

H Large Icons

H Small Icons

H Details

The first two are basic views: you can view the service icons as either small or large icons. In both cases, if the transport stream encodes the name for the service, the name appears with the icon. If no name is provided, the service icon is identified by the Transport Stream ID | Service ID (TSID | SID) pair. You can display the TSID | SID pair by pausing your cursor over a service icon; a tool tip is displayed showing the TSID | SID pair.

The Details view of the Services panel is shown in Figure 3--2. Display this view by right-clicking in the Services panel and selecting Details from the shortcut menu.

Figure 3- 2: Details view of the Services panel

The Details view provides the following information in tabular format (listed from left to right):

H Service Name. Displays an icon for each program or service and lists the

service name for each input (if service names are provided in the transport stream)

H TSID. Displays the TSID for the selected I/O port.

H Service ID. Displays the SID for the program or service.

H Host name. Displays the name of the MTS300 system to which you are

connected.

H IP Address. Displays the IP address of the MTS300 system to which you are

connected.

H Input name. Displays the I/O port number on the MTS300 system to which

you are connected (I/O#1, I/O#2, I/O#3, or I/O#4).

H Error level. Displays the error-severity level of the current error (if there is

no current error, the report is “no error”).

You can sort the icons in the Service panel by name, error, TSID, or SID using the Services panel shortcut menu.

Error Icons. When you select a service experiencing an error in any of the Services panel views, the Details panel updates to display more information about the errors detected for that service.

The error icons that overlay the icons in the Service panel are used to show the status of errors on the input:

H Red error icons indicate that an error is detected for the monitored service.

H Orange error icons indicate that the service recorded one or more errors, but

that the error condition no longer exists.

Details Panel

H Yellow error icons indicate that a warning condition exists for the monitored

service.

The Details panel displays icons representing error status, types, and levels for a selected service or multiplex. You can resize the height of the Details panel by clicking and dragging the top panel border.

The Details panel contains icons only if you have selected a multiplex or service icon that has an error associated with it. If the selected multiplex or service icon has no errors (past or present), or if you click in the white space of the Multiplex or Service panel, the Details panel goes blank.

From left to right in the Details panel, you will see the types of icons indicated in the following list (see Master Client Toolbars and Icons beginning on page 3--17 for more information about these elements):

H Error severity gauge indicating the highest error level, current or past, for the

selected item (multiplex or service)

H Icons that represent the selected multiplex or service

H Icons indicating the service error types, current or past, for the selected

service

3- 16

H Icons indicating the multiplex error type, current or past, for the selected

multiplex

The last two list items are mutually exclusive: the Details panel displays one or the other, not both at the same time.
