Section 1. Using This Guide This guide describes how to install and use a WavePhore Intelligent Data Receiver™ V1000 (IDR V1000). The IDR V1000s comprise a family of satellite receivers that receive, demodulate, and process data streams over high-speed carriers. These data streams supply real-time news, market information, and other subscription services to businesses. The IDR V1000 family includes four models.
Using This Guide Audience Two types of audiences are assumed to be users of this guide: The primary audience is the technical user who is assumed to have a working knowledge of satellite and telecommunications equipment. These users include installation technicians, network operators, and on-site technical staff who work directly with the equipment to install it, verify its functionality, or perform network maintenance or troubleshooting procedures.
Using This Guide • • Terminology terms abbreviations and acronyms Glossary The terms “IDR,” “IDR V1000,” or “the receiver,” used in this manual, refer to all of the IDR V1000 models. A specific model is noted where the information applies only to that model. Terms that are unique to the IDR V1000 or WavePhore products are defined in context, as well as included in the Glossary. Industry-standard terms, acronyms, and abbreviations are listed and defined in the Glossary.
Using This Guide Safety Issues Following some basic, common-sense procedures will protect you and will help keep the IDR V1000 operating without disruption. Do: • • • Unplug power before changing external cables. This reduces the chance of electrical shorts that could damage the receiver. Protect the IDR V1000 from liquids and excessive heat, humidity, or dust. These elements can damage or wear electrical components. Connect the IDR V1000 to grounded power outlets. Do Not: • Open the casework.
Section 2. Installing the IDR V1000 The installation process covers the following steps: 1. Ensuring all cables are properly connected. 2. Tuning the IDR V1000 to its maximum achievable levels for that site 3. Notifying the network operator that installation is complete and to download the appropriate services as necessary. For more descriptive detail on the screen displays, refer to Sections 3 and 4. Before You Begin: First, verify the current conditions: 1.
Installing the IDR V1000 Step 1: Connect The Cables 1. Connect the coaxial cable to the RF Input connector 2. Connect data cables between the serial or Ethernet outputs on the IDR V1000 and the external devices. See Figures 2-1 and 2-2. 3. Connect the power module to the IDR V1000 power input and to the power source. Figure 2-1. Rear Panel Connectors, 4-Port Daughtercard Figure 2-2. Rear Panel Connectors, Ethernet Output 2–2 MS-4900, Rev.
Installing the IDR V1000 Step 2: Verify Initial Lock On Carrier As soon as power is supplied to the IDR V1000, an automatic self-test runs. The IDR V1000 then locates and “locks” onto the preset frequency. When this completes successfully, the following identification screen appears (Figure 2-3). IDR V1000 Model # ©1997 WavePhore 00:00 1236 S/N:xxxxxxxx L L = locked on signal Figure 2-3.
Installing the IDR V1000 Step 4: Call the Network Operator Step 5: Maintain the Equipment 2–4 Once the Eb/N0 and AGC readings are at the expected levels and the Eb/N0 has been maximized by adjusting the dish alignment, notify the network operator that the receiver has been installed and is ready to be downloaded. The operator may provide you additional instructions following the download.
Section 3. Using the Front Panel This section describes how to use the front panel of the IDR V1000 to view or modify receiver settings. This information includes the following: • • • Displaying and deleting messages Viewing and modifying configuration parameters Changing screen locks, password access, and local time Configuration parameters typically are preset at the factory or are downloaded by the network operator.

Section 4. Interpreting Screen Displays The IDR V1000 screens provide detailed information on the status of the receiver, the satellite signal, the received data, and the output ports. This section describes how to interpret the screen information to troubleshoot problems or to monitor IDR V1000 status. The descriptions of the screens are organized in the order of the troubleshooting steps listed in Table 4-1.
Interpreting Screen Displays Check Signal Quality The “superscreen” under the Show Status topic provides a quick summary of signal status, but most of the fields relate to stat mux operation (*): CRC errors* Link block frame loss* Incoming packet counter* or character counter Carrier lock status 0 X 0 0 Modulation type 0L BPSK 0 0 0 0 Not applicable Type of data Packet framing errors* Not applicable Corrected FEC errors* Uncorrected FEC errors* Figure 4-1.
Interpreting Screen Displays Table 4-3.
Interpreting Screen Displays TDD Screen Fields The time-division de-multiplexer screen reflects control channel information logged by the TDD. This screen is meaningful with all data modes. Cluster ID Carrier ID Cluster:00000 CID: 255 CTL CH: IdOkNow PKT:000 Control channel status Valid control packets Figure 4-3. TDD Screen Table 4-5.
Interpreting Screen Displays Active Sessions Screen Fields This summary screen lists the total number of active sessions for all logical receivers, and is meaningful only in terms of stat mux processing. An active session means the receiver currently has data addressed to it and is passing it to the output ports. NOTE: Logical receivers are available only with stat mux processing, which has the capability of addressing those virtual destinations. (See “Functional Overview”.
Interpreting Screen Displays Check Output Ports Evaluate the output error indications based on whether output was being displayed successfully: Output data has been displaying successfully and has suddenly stopped: Check flow control and logical receiver memory utilization, as indicated in the following Show Status screens. Frequently, overflow problems occur within the software on the external device; rebooting the attached PC may clear the problem.
Interpreting Screen Displays Table 4-7.
Interpreting Screen Displays Table 4-8.
Interpreting Screen Displays Check Output Ports (cont’d) The Diagnostics screens provide a serial port test through which you can send a repeating test pattern to the designated port. Diagnostics: Test Serial 1 Serial 1 Output Test in Progress The test pattern continues through that port until you press the CANCEL button. Any network data output received during the test is interleaved with the test pattern. NOTE: The test pattern is selected through the Set Features/Diagnostic Out Style screen.
Interpreting Screen Displays Verifying Ethernet Screens Additional screens within the View Setup and Specify Setup main topics provide information relevant to the Ethernet model of the IDR V1000. This section describes the contents of those screens. NOTE: The following screens do not appear on IDR V1000 models other than the Ethernet model. View Setup The first logical receiver (Receiver 0) refers to the stat mux logical receiver within the IDR V1000.
Interpreting Screen Displays SNMP Trap IP Address This is the address of the computer running the SNMP manager software and to which the IDR V1000 can report its status events (such as acquiring or losing carrier lock). Assuming both the SNMP server and the IDR V1000 are connected to the Internet, you can poll the receiver status from anywhere in the Internet. NOTE: This address must be set to either the SNMP manager address (to report status), or all zeroes (to not report status).
Interpreting Screen Displays Examining System Messages You can examine system messages to get an indication of receiver activity over a span of time. The IDR V1000 stores up to three user messages and three system messages in memory, each of which reflects an event in the receiver’s operation. For example, the initial system message when the receiver is first powered on indicates it is not locked to a carrier. As soon as the receiver acquires a lock on the carrier, the system stores that message.
Section 5. Functional Overview This section describes the function of the IDR V1000 within a WavePhore network: • “Network Overview” gives the “big picture” from point of origin to display on • “Modes of Moving Data” describes some of the fundamental terms and concepts you need to understand first. “IDR V1000” describes the functional characteristics of the IDR V1000 itself.
Functional Overview The NCC: Input and Output Input to the NCC consists of data feeds arriving through the access network. This can be data originating from a remote or local computer. Some of this data is processed in the statistical multiplexer, commonly called a stat mux. The stat mux assembles that data into a series of packets. The packets contain information about the data, such as message length, source, specific output destination, encryption or compression keys, as well as the data itself.
Functional Overview Figure 5-1. A Sample Wavephore Network and the Flow of Data MS-4900, Rev.
Functional Overview The Receiver: Input and Output Input to the IDR V1000 comes from the satellite dish. The downlinked data stream is amplified and shifted to a lower frequency by the LNB on the satellite dish and passed through the coaxial cable to the IDR V1000. The receiver demodulates the data, converting the analog signal to digital data, and tries to correct reception errors before moving the digitized data stream to the time-division demultiplexer, or TDD.
Functional Overview Stat Mux Data Statistically-multiplexed data contains the message itself—a part of a news story or weather report—along with overhead information about the message, such as its length, its origin, and its destination. Destination information directs data to a specific logical receiver within the IDR V1000. Logical Receivers Stat mux operation has the capability of addressing messages to virtual, or logical, receivers within an IDR V1000.
Functional Overview Table 5-1 reflects the availability and usage of the five possible serial ports, depending on the nature of the received data: transparent asynchronous, statisticallymultiplexed, or transparent synchronous, or combinations thereof. NOTE: The functionality of Serial 4 port is dependent on the hardware configuration established at the factory. Table 5-1.
Functional Overview PAD Mode and PVC Sessions PAD mode ports output original news stories directly. For PVC sessions, the output is straightforward: for any PVC session (of which only one is deliverable to any PAD logical receiver), incoming stories are delivered to the logical receiver in proper sequence from the head end, and the IDR V1000 delivers those stories exactly as received.
Functional Overview IDR V1000: Functional Overview The IDR V1000 receives, demodulates, and corrects errors in the transmission, disassembles the data stream to extract discrete messages, processes the blocks and packets of information for display, and can monitor and log its own operation.
Functional Overview Signal Input: LNB and Tuner The IDR V1000 connects to the LNB on the satellite dish through the coaxial cable attached to the rear panel RF connector. The LNB (low noise block converter) receives power from the receiver, maps satellite signals to a pre-determined range of frequencies (950 to 1525 MHz) and sends the appropriate commands to the tuner. The tuner selects the specific signals (out of many delivered by the LNB) that contain the desired aggregate data stream.
Functional Overview Figure 5-4. Reed-Solomon Model, Functional Depiction Time-Division Demultiplexer (TDD) After the signal has been demodulated and passed through error-correction, the aggregate data stream moves into the time-division demultiplexer, or the TDD. The TDD separates the data stream into partitions.
Functional Overview demultiplexing capability. As shown in Figure 5-3, the processor connects to the tuner, controlling its frequency setting and the bit rate used by the demodulator. The processor programs the TDD at start-up to match the frame image stored in memory. The TDD routes the aggregate data according to this image. Some of the bits in the frame can be routed to the processor and may be processed there by the statistical demultiplexer.
Functional Overview Buffering and Flow Control Buffering and flow control are important concepts related to moving the data through the output ports. The buffer is the area of RAM in the IDR V1000 allocated to temporarily store processed data when the external computer is unready or unable to accept it. As soon as the external computer can accept incoming data, the buffers empty as the data is moved out of the receiver.
