Page 11: Introduction
1 INTRODUCTION The Motorola OM 2000 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 an RF output signal for transmission over the cable system. -

Page 17: 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 2000 accepts this information and processes it for delivery on the OOB channel by combining it into an MPEG-2-compliant transport multiplex and outputting that transport multiplex as an RF signal. -
Page 18: Functional Overview
OOB data transmission. OOB Signal Processing In converting the OOB data inputs into an RF signal, the OM 2000 performs the following OOB signal processing functions: • Receives the cable terminal control stream and other OOB data from multiple input sources •... - Page 19 Figure 2-2 — OOB data flow through the OM 2000 Receiving OOB Data Inputs The OM 2000 can receive OOB data through multiple input ports. All data ports are located on the back panel, and each has a unique numeric identifier. Table 2-1 describes the OM 2000 input ports: Table 2-1 —...
- Page 20 2 OVERVIEW In general, OOB data input to the OM 2000 must be in MPEG-2 transport packets. Data sent to configure, control, and boot the OM 2000 need not conform to MPEG-2 format. Multiplexing the OOB Data The packet multiplexer combines OOB data from the Ethernet and serial input ports into a single MPEG-2-compliant transport multiplex, and then routes this multiplex to the RF modulator.
- Page 21 Depending on your system configuration, the cable-terminal control-stream input to the OM 2000 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 22 2 OVERVIEW PID 0 and PID 1 packets, as well as commands specifying how often the generator should insert the packets into the multiplexer. Generating the RF Output The RF modulator receives the OOB data transport multiplex created by the packet multiplexer and performs the following functions to convert it for RF transmission: Forward error correction An FEC encoder performs Reed/Solomon encoding, data...
