MODULATOR OUT OF BAND DATA  531564-001The Motorola OM 2000 Out-of-Band Multiplexer/Modulator generates an out-of-band (OOB) data stream from the headend to digital cable set-top devices, either individually or on a broadcast basis. The OM 2000 can be configured to receive data over Ethernet using UDP/IP, or as serial data over RS-530 or RS-232 communications links. The OOB data stream is used primarily as a signaling channel, but is also used to transmit electronic program guide (EPG) information and code download data. The out-of-band data stream is also the downstream path in an interactive system.

A Quadrature Phase Shift Key Modulator (QPSK) modulates the data on a 1.8 MHz-wide carrier. The center frequency is agile across the 71 to 129 MHz band. The OM 2000 uses null packets as necessary to perform rate aggregation between its inputs and the 2.048 Mbps output. Forward Error Correction (FEC) encoding and interleaving protects data integrity.

• Receives UDP/IP Ethernet and RS-530 or RS-232 serial data from multiple external devices

• Combines multiple sources of data into one MPEG-2 output transport stream

• Transmits an MPEG-2 data stream (authorization information, EPG data, code downloads, interactive data, and emergency alert packets) to cable terminals, individually or on a broadcast basis

• Provides FEC encoding of the output bitstream, interleaving, and randomization

• Provides QPSK-modulated output in a 1.8 MHz carrier in RF (71 to 129 MHZ) or IF (44 MHz)

• Provides variable RF power control

• Provides status and alarms via SNMP traps

• Maintains a contact closure connection with an EAS generator, and transmits EAS messages when trigged by the contact closure

• Performs periodic insertion of internally stored messages

• Front-panel display indicates chassis IP address
