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.
Section 3 Installation provides instructions on how to install the OM 1000. Section 4 Setup and Operation provides instructions on how to set up and operate the OM 1000. Section 5 Troubleshooting provides problem solving, testing, and maintenance information. Appendix A Specifications provides the technical specifications for the OM 1000.

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.
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.
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.
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.
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.
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.
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...
Overview Physical Overview The OM 1000 chassis mounts in a standard 19-inch equipment rack in a digital headend, network hub office, or network end office. It occupies one rack unit (1.75 vertical inches) and requires a blank panel with one rack unit of space above and below it for cooling airflow.
Overview Controls and Indicators The OM 1000 controls and indicators, as well as the RF monitor jack, are located on the front panel. Figure 2-6 illustrates the front-panel controls and indicators: Figure 2-6 OM 1000 front panel TEST OM 1000...

CAUTION! Improper grounding may damage the OM 1000. Refer to the national guidelines or local standards for the OM 1000 proper grounding to equipment racks and to the building grounding system. To mount the unit in the rack:...
Optional ground wire connection CAUTION! To avoid possible damage to the OM 1000, ensure that the ac-power cord is disconnected before connecting any I/O cables. Connecting Ethernet and Modulator Output Cables For most applications, the RF modulator must be connected to the distribution system. Figure 3-2 illustrates a typical connection for Ethernet and modulator output.
To connect to a serial port: Align the male pins on the DB9 connector with the female connector marked 232 I illustrated in Figure 3-3: Figure 3-3 OM 1000 optional serial and interface output connection RS-232 DB9 to/from out-of-band RS-232 or data providers...
Connect the AC-power cord after all I/O connections are complete. The power supply automatically senses and adapts to any input from 85 through 264 Vac, at 47 through 63 Hz. The OM 1000 meets all specifications with an AC input from 100 through 240 Vac, 50 through 60 Hz.
CAUTION! Any changes you make to operate parameters apply only to the current OM 1000 operating cycle and will be lost when you power down the unit. To save changes to flash memory as default settings at subsequent power ups, select SAVE from the ADMIN menu and then press .
Setup and Operation Menus OM 1000 front-panel LCD functionality is partitioned into six menus as listed in Table 4-1: Table 4-1 Menus Menu Title Function MAIN Main Provides access to the other menus to configure physical ports, logical ports, and the network.

RAM disk, the unit broadcasts BOOTP requests over the Ethernet for up to 10 seconds. If the OM 1000 receives a response from the server, a new boot file transfers to the OM 1000 through the Ethernet. The information in the BOOTP response includes the unit IP address and subnet mask, the IP address of the host server, and the full path name of the boot file.
Page 36
CAUTION! If the BOOTP server is NOT on the local network, the OM 1000 will not be reloaded with software and will not be rebooted. Erasing OM 1000 software should only be done when a new version of OM 1000 software is to be loaded onto the OM 1000.

For example, if x = 10 and y = 5, then the OM 1000 would have to drop 50 packets over a five-minute time frame to create an alarm condition. The OM 1000 calculates the number of drops approximately once every minute.
The number of occurrences where the continuity count is not contiguous is used as a trigger to send out SNMP traps based on user-defined thresholds. The OM 1000 sends a major alarm when it has detected that the user defined threshold for such occurrences has been exceeded.

(an “F” at the end of the line listing the file), the listed file is then downloaded to the OM 1000. If the downloaded FOF and the OM 1000 local copy are the same and a force download flag does not exist in the FOF, the OM 1000 does not download any additional files. It continues booting using the values stored in flash memory.

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.
