For a 3-prong plug (consists of two blades and a third grounding prong), insert the plug
into a grounded mains, 3-prong outlet.
Note: This plug fits only one way. The grounding prong is provided for your safety. If
you are unable to insert this plug fully into the outlet, contact your electrician to replace
your obsolete outlet.
For a 2-prong plug (consists of one wide blade and one narrow blade), insert the plug
into a polarized mains, 2-prong outlet in which one socket is wider than the other.
Note: If you are unable to insert this plug fully into the outlet, try reversing the plug. The
wide blade is provided for your safety. If the plug still fails to fit, contact an electrician to
replace your obsolete outlet.

Introduction
This chapter illustrates how the Multiple Amplitude Modulation modulator
(MQAM) functions within the Digital Broadband Delivery System (DBDS),
describes MQAM processing, and describes the front and back panel of the
MQAM.

Chapter 1 Introducing the MQAM
2 78-717866-01 Rev D
System Overview
The MQAM delivers compressed and encoded, multi-program Moving Picture
Expert Group (MPEG) transport streams of interleaved voice, video, and data in the
RF spectrum to Digital Home Communications Terminals (DHCTs). The MQAM
performs the following functions within the DBDS:
Uses two ASI inputs to allow:
-MPEG stream multiplexing of two MPEG data sources
-Use of the second input as a redundant port
Allows direct input from a variety of MPEG data sources at various rates, such as
video-on-demand (VOD) servers, SONET-to-ASI converters, Grooming BIGs,
and Multiple Decryption Receivers (MDR)
Processes an MPEG transport stream (TS) at various rates
Allows Stream Encryption and Management
Contains four, independent RF Output channels, allowing the MQAM to use
only one unit of rack space for the MQAM hardware and one unit of rack space
for ventilation while replacing the RF output capabilities of four D9476 QAM
Modulators
Features
The MQAM provides many digital broadcast features and innovations for your
system. The following table describes these features and innovations.
Feature Function
Dual ASI Inputs Supports maximum ASI data rate at both inputs (216 Mbps
each)
Multiplexing
Functionality
Program and Packet Identifier (PID) remapping and filtering
Full routability of MPEG programs. The MQAM can route any
MPEG program from both of its inputs to any combination of
outputs.
Single programs can be sent to any combination of the four RF
outputs simultaneously (multicast).
