The exclamation point, within an equilateral triangle, is intended to alert the user to
the presence of important installation, servicing, and operating instructions in the
documents accompanying the equipment.
For continued protection against fire, replace all fuses only with fuses having the
same electrical ratings marked at the location of the fuse.
Electrostatic discharge (ESD) can damage the OM unit and circuit card asOMblies.

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.
Figure 1-1 illustrates the OM 2000:
Figure 1-1 — OM 2000 Out-of-band Modulator
The OM 2000:
•Receives Ethernet User Datagram Protocol (UDP) packets from a controlling
processor
•Multiplexes downstream data from multiple sources
•Provides forward error correction (FEC) encoding of the bitstream, as well as
interleaving and randomization
•Provides downstream QPSK-modulated output within the 71 to 129 MHz range
•Provides industry-standard Ethernet 10Base-T connectivity for operation,
administration, maintenance, and provisioning (OAM&P)
•Performs periodic insertion of internally stored messages
•Controls and provides status/alarm reporting using Simple Network Management
Protocol (SNMP)

2 OVERVIEW
The Motorola OM 2000 creates a QPSK-modulated signal to carry the out-of-band
(OOB) datastream of a digital CATV system from the headend to set-top devices
(STDs) installed in subscribers’ homes. The OOB datastream is the control link
through which the headend transmits the commands and authorization messages
that control the STDs distributed throughout the CATV system. The headend can
also use the OOB datastream to deliver other types of information, including:
•Electronic Program Guide (EPG) information
•Application code downloads
•Control messages for emergency situations
•Data services
•Executable code downloads to fix or upgrade cable terminal operation
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. Other output formats are also available to
support specific application requirements.
Figure 2-1 illustrates the operational flow through the OM 2000:
Figure 2-1 — OM 2000 operational flow diagram

2 OVERVIEW

Functional Overview
The OM 2000’s primary function is to combine multiple OOB data inputs into a
single datastream that is transmitted over the OOB channel as an RF signal. The OM
2000 also provides additional signal-processing functionality:
Serial data communications To support other application requirements, the OM 2000
transmits and receives baseband digital data over
various serial data ports.
Emergency alert operation The OM 2000 can monitor an emergency alert remote
control unit and receive and store special cable terminal
control messages. When a relay closure is sensed, the
special messages are inserted into the 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
•Multiplexes the information into a single, packet-based, MPEG-2-compliant
transport stream
•Inserts PID 0 and PID 1 control streams into the transport stream, if necessary
•Modulates the digital transport stream onto a 1.8 MHz-wide RF carrier using
QPSK modulation
•Upconverts the resulting signal into an RF output with a center frequency in the
71 through 129 MHz range. (An IF output is available for optional external
upconversion to other frequencies.)
Figure 2-2 shows the typical flow of OOB data from the input port(s) through the
packet multiplexer to the RF modulator:

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 — OM 2000 input ports
Port Type Port ID Description
RS-232 DB9 pin serial data
(Front)
1 A standard RS-232 serial data port for an external
terminal (console) port is used for internal diagnostics.
RS-232 DB9 pin serial data
(Rear)
2 A standard RS-232 serial data port (asynchronous only)
receives EPG information, code download, and other
OOB data types. In some systems, an RS-232 port is
configured to receive cable-terminal control-stream
information instead of, or in conjunction with, the
Ethernet port.
Ethernet 1 3 The standard Ethernet port is the primary input to the
OM 2000. Because it is an Ethernet connection, port 3
supports communication with multiple devices over
the same physical port.
Generator port GEN The MPEG message generator is a virtual input only
port that supplies MPEG messages at periodic
intervals to the output ports configured by the
datapipe. The control interface sets the insertion
interval, availability status, and the message data.
RS-530 DB25 serial data 4 The RS-530 serial data port is an expansion port that
can be used in the same way as port 2. Like the
standard serial data ports, port 4 can be configured for
input or output operation.
Ethernet Not supported in initial release.

2 OVERVIEW
10
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. The multiplexer can also accept input data from special internal
sources (for example, the internal generator for emergency alert messages or for
PID 0 and PID 1 control data) if necessary.
Caution!
The aggregate input rate of all data to be combined into the RF
output must not exceed 2.005 Mbps. If the rate is lower than
2.005 Mbps, the multiplexer will add null packets to achieve the
correct data rate. If the aggregate input rate is higher than
2.005 Mbps, the multiplexer will drop packets.
The main destination for most OOB data is the RF modulator; however, the
multiplexer can route data to other output destinations. Each input packet stream
can be routed to up to three different output destinations. Table 2-2 lists the available
destinations.
Table 2-2 — Multiplexer output destinations
Destination Description
RF modulator The RF modulator uses QPSK modulation to convert an MPEG-2-
compliant transport multiplex into a 1.8 MHz-wide RF signal with a
center frequency between 1 and 129 MHz. Data directed to this
destination is output from the RF Out and IF Out connectors on the OM
2000 back panel.
Serial data ports Data directed to a serial data port is output as a serial datastream. The
serial data ports are valid destinations only when configured as output or
bi-directional ports.
UDP connections over
the Ethernet port
Data directed to a UDP port is output as a serial datastream. The UDP
connections are valid destinations only when configured as output ports.
A legal UDP port number must be assigned to each connection, and the
IP address of the receiving device must be configured.
Null port 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 2000 relies on a collection of data-handling specifications called PID maps to
support the proper multiplexing and routing of data through the packet multiplexer.
One set of PID maps is defined for each input port to control how the multiplexer
handles packets from those streams. Within the set for a port, a single PID map
controls the handling of one packet stream, and each set includes a default PID map
to control the handling of packet streams having no explicit PID mapping.
