About This Guide
Introduction
This guide describes both the intermediate frequency (IF) Gigabit Overlay
Quadrature Amplitude Modulation (GoQAM) modulator and the radio frequency
(RF) GoQAM.
Note: In this guide, the GoQAM modulator is referred to as the GoQAM.
The RF GoQAM is a software-modified Model D9479-1 Gigabit QAM (GQAM)
Modulator. The Model D9479-3 IF GoQAM is similar to the RF GoQAM, but has IF
outputs in lieu of RF outputs, as well as a different back panel. Both are integral
components of Cisco Overlay solution. The Overlay solution uses Digital Broadband
Delivery System (DBDS) technology to create a network in which different
conditional access (CA) systems can coexist in a coherent manner. Overlay
technology allows a PowerKEY
®
DBDS network to be “laid over” an existing cable
network that uses a different CA system.
Important: The GoQAM requires System Release (SR) 2.5/SR 3.5 (or later) with the
Overlay feature enabled.
Purpose
This guide provides detailed specifications and component descriptions for the
GoQAM and how the GoQAM functions in Cisco’s Overlay solution. This guide also
includes all of the procedures that enable you to install, provision, and operate the
GoQAM within your cable network. Call center personnel can use this guide to
assist them with common troubleshooting procedures.
Scope
This guide includes the following topics:
Descriptions of GoQAM functions
Descriptions of GoQAM components
Installation procedures
Operation procedures
Troubleshooting guidelines
Customer information
IF and RF GoQAM technical specifications

Audience
This guide is written for cable network system administrators and engineers,
operators of the Overlay DNCS, call center personnel, and system operators who are
responsible for installing, operating, maintaining, and troubleshooting the GoQAM.

Introduction
This chapter describes how the GoQAM functions within the Overlay
environment, explains how the GoQAM processes and outputs data, and
provides illustrations and descriptions of the front and back panel
components for both the IF and the RF versions of the GoQAM.

provision (configure) a GoQAM on your system.

System Overview
Diagram of Cisco’s Overlay Solution
The GoQAM is an integral component of the Overlay solution. The Overlay solution
uses Digital Broadband Delivery System (DBDS) technology to create a network in
which different conditional access (CA) systems can coexist in a coherent manner.
Overlay technology assumes that a PowerKEY DBDS network will be “laid over” an
existing but different cable network.
Important! The GoQAM is supported in SR 2.5/SR 3.5 (or later).
Depending on the system architecture, the GoQAM can be used in either headends
or hubs. The following illustrations are examples of typical Overlay environment
setups.
Overlay Environment Without a Multiplexer With an IRT
In an Overlay environment without a multiplexer (MUX), the Integrated Receiver
Transcoder (IRT) does the encryption for the non-Cisco set-tops.
The following graphic illustrates how Overlay technology interfaces to a non-Cisco
headend that uses a simple IRT. The IRT performs a number of functions including
Mediacipher encryption. With an IRT, clear and encrypted signals are available
through DHEI connectors on the IRT back panel.
System Overview
4004834 Rev D 3
Overlay Environment With a MUX
In an Overlay environment with a MUX, the Modular Processing System (MPS) does
the encryption for the non-Cisco set-tops. The following graphics illustrate how
Overlay technology interfaces to a non-Cisco headend that uses a multiplexer
followed by an MPS. The MPS performs Mediacipher Encryption and may perform
QAM modulation, depending upon the specific device.
Example 1:
Example 2:
Note: The MPS is being replaced by the SmartStream Encryptor Modulator (SEM).
As with the MPS, a number of different options are available for interfacing Overlay
technology with the SEM. Specific details can be obtained by contacting Cisco
Services.

Features
The GoQAM provides many new digital broadcast features and innovations for your
system. The following table describes these features and innovations.
Feature Function
DVB ASI Input pairs
Supports a maximum ASI data rate of 216 Mbps (MPEG
packet rate) at all four inputs
Accepts two pairs of inputs. Each pair consists of an
incumbent-encrypted stream and its corresponding clear
stream. The GoQAM extracts critical packets—those without
which video cannot be reconstructed—and encrypts them
using Cisco PowerKEY encryption technologies. The GoQAM
also extracts the corresponding critical packets from the
incumbent-encrypted stream. Later, the PowerKEY packets
and the incumbent-encrypted critical packets are multiplexed
with the portion of clear stream that has not been encrypted.

GoQAM Input Pairs
The GoQAM associates the DVB ASI inputs as pairs of clear and encrypted inputs
for Overlay purposes. This means that each DVB ASI input constitutes a dedicated
pair of clear and encrypted streams. Each pair carries a clear digital broadcast stream
on one input and its encrypted form on the other input. For example, ASI IN 1 and
ASI IN 2 carry the clear and encrypted forms of the same digital transport stream,
respectively.
GoQAM Input Pairs Diagram
RF GoQAM Example
The following illustration depicts the fixed input and output combinations for an
RF GoQAM.
Note: For the RF GoQAM, input pair 1 can only be mapped to RF OUT 1, and input
pair 2 can only be mapped to RF OUT 3.
IF GoQAM Example
The following illustration depicts the fixed input and output combinations for an
IF GoQAM.
Note: For the IF GoQAM, input pair 1 can only be mapped to IF OUT 1, and input
pair 2 can only be mapped to IF OUT 2.
Input/Output Process
4004834 Rev D 7
Input/Output Process
This section describes how the GoQAMs modulate, encrypt, and transmit the signals
they receive from external sources.
Input/Output Dia gram (RF Version)
The following diagram illustrates the stages of the input/output (I/O) process for
the RF GoQAM.
Note: The stage numbers correspond with the following table.
Input/Output Sta ge/Descript ion Table
The following table describes the stages of the I/O process of the RF GoQAM. The
numbers correspond to the above I/O diagram.
Stage Description
1 A pair of transport streams (a clear version and a third-party encrypted
version of the same stream) are input to the modulator.
2 The digital I/O board timestamps the MPEG packets in each stream, then
filters and routes them according to their PID values.
3 The digital I/O board selects the packets to pass from both the clear and
third-party encrypted streams.
4 PowerKEY encryption is added to selected clear packets and PID values are
remapped.
5 The clear and encrypted streams are synchronized.
6 An overlay output stream is created by muxing (multiplexing) the clear, S-A
encrypted, and third-party encrypted packets.
7 The output stream is modulated at 64 QAM or 256 QAM.
Chapter 1 Introducing the GoQAM
8 4004834 Rev D
Stage Description
8 The I/O board directs the transport stream to one of the two RF Agile output
converters and sends the signal through the RF network to the DHCTs.
This section provides the installation process and lists the detailed procedures in this
guide that correspond with each process step.
Important: To ensure proper installation, read this entire guide before starting
installation and then follow these processes in the order shown.
