  • Page 6: Section 1. Using This Guide

    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.

  • Page 7: Audience

    The second type of audience may not deal directly with the equipment, but needs a general understanding of the context in which the IDR V1000 operates and an overview of the receiver’s operational capabilities. Organization Sections 2 and 3 are intended for the technical user who needs procedures for installing the IDR V1000 and verifying or troubleshooting its operation.

  • Page 8: Terminology

    • abbreviations and acronyms Terminology 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.

  • Page 9: Safety Issues

    Interpreting Screen Displays Active Sessions This summary screen lists the total number of active sessions for all logical receivers, Screen Fields 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.

  • Page 31: Verifying Ethernet Screens

    NOTE: Be sure to communicate to the network control center any IP address changes that are made onsite. Local IP Address This is the IDR V1000 address on the end user’s local area network. It identifies the receiver as a node on the LAN. Subnet Mask The subnet mask can be used to prevent the IDR V1000 from establishing point-to- point connections with individual PCs outside the defined subnetwork.

  • Page 32: Snmp Trap Ip Address

    (to not report status). Host IP Address The host IP address is that of the end user PC receiving the IDR V1000 output data. This establishes a point-to-point connections between the IDR V1000 and the individual PC. A valid address is required in this screen if the IDR V1000 must initiate the connection to the PC using either a TCP/IP socket connection or a Unicast socket connection based on UDP packets.

    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.

  • Page 35: The Ncc: Input And Output

    Functional Overview Input to the NCC consists of data feeds arriving through the access network. This The NCC: can be data originating from a remote or local computer. Some of this data is Input and processed in the statistical multiplexer, commonly called a stat mux. The stat mux Output assembles that data into a series of packets.

  • Page 38: Stat Mux Data

    (Serial 1 through 4). Most of the IDR V1000 status screen displays relate to statistically-multiplexed packets and their destinations to one of four logical receivers within the IDR V1000. Data handling in stat mux mode is more flexible than the transparent pass-through data handling that occurs with transparent synchronous or asynchronous data.

  • Page 39: Tvcs And Pvcs

    PAD and Node Each stat mux output port of the IDR V1000 is configured to deliver data in either PAD or Node mode. The mode determines the manner in which the received data is Modes sequenced and output.

  • Page 40: Pad Mode And Pvc Sessions

    Instead, to ensure that a TVC news story is delivered intact and that news stories do not blend together, the IDR V1000 in PAD mode acts in a special way: While any particular story of a logical receiver is being output, other stories accumulate in the IDR V1000 buffer.

  • Page 44: Statistical Demultiplexer (Stat Demux)

    The UART chip in the processor drives the Serial 1 output to an external device. (The Serial 1 port is the only output port in an IDR V1000 basic unit.) Statistical Packetized data, sent in stat mux format from the NCC, is de-multiplexed (and de- packetized) in the receiver.

  • Page 45: Buffering And Flow Control

    If the output device cannot handle the data coming into it from the IDR V1000, it signals the IDR V1000 to suspend the data flow, using one of four methods. The IDR V1000 buffers the data until it receives another signal to continue data flow.
