    Section 1 Introduction The Motorola OM 1000 Out-of-band Modulator links the digital headend equipment with the distribution system by combining the various out-of-band inputs into a quadrature phase shift key (QPSK)-modulated signal. It converts multiple digital input streams into a RF output signal for transmission over the cable system.

    Introduction Calling for Repairs If repair is necessary, call the Motorola Repair Facility at 1-800-642-0442 for a Return for Service Authorization (RSA) number before sending the unit. The RSA number must be prominently displayed on all equipment cartons. The Repair Facility is open from 7:00 AM to 4:00 PM Pacific Time, Monday through Friday.

  • Page 14: Overview

    Other devices in the headend create the specific commands, messages, and downloadable code that make up the information contained in the OOB datastream. The OM 1000 accepts this information and processes it for delivery on the OOB channel by combining it into a Motion Picture Expert Group-2 (MPEG-2) compliant transport multiplex and outputting that transport multiplex as an RF signal.

  • Page 15: Functional Overview

    Overview Functional Overview The primary function of the OM 1000 is to combine multiple OOB data inputs into a single datastream that is transmitted over the OOB channel as an RF signal. The OM 1000 also provides serial data communications to transmit and receive baseband digital data over various serial data ports.

  • Page 16: Receiving Oob Data Inputs

    Refer to the operate.txt file in Appendix C, “Initialization Information” for configuration information. In general, OOB data input to the OM 1000 must be in MPEG-2 transport packets. Data sent to configure, control, and boot the OM 1000 need not conform to MPEG-2 format.

  • Page 17: Multiplexing The Oob Data

    The null port is a conceptual destination equivalent to routing a packet to nowhere (that is, discarding the packet). Because of the number of possible input sources and output destinations, the OM 1000 relies on a collection of data-handling specifications called PID maps to support the proper multiplexing and routing of data through the packet multiplexer.

  • Page 18: Inserting Pid 0 And Pid 1 Control Streams

    Depending on your system configuration, the Digital Consumer Terminal (DCT) control-stream input to the OM 1000 can include the PID 0 and PID 1 control streams required to define the OOB transport multiplex. If not, these streams are added to the multiplex before it is input to the RF modulator.

  • Page 19: Generating The Rf Output

    PID maps, the packet multiplexer directs input packets to serial data port destination queues and multiplexes them into output datastreams in the same way it routes and multiplexes data for the RF modulator. Serial data ports must be configured as output ports to be valid output destinations. OM 1000 Installation and Operation Manual...

    The hosts file, specified in the FOF, defines the names and IP addresses of all other devices in the headend LAN with which the OM 1000 must communicate. In the hosts file, all lines must be either comment or data lines, and each line must be terminated with a carriage return or a carriage return plus line feed.

    Initialization Information Services File Format The services file specified in the FOF defines the TCP/UDP ports the OM 1000 uses to communicate with other devices in the headend LAN. Within the services file, all lines must be either comment or data lines, and each line must be terminated with a carriage return or a carriage return plus line feed.
