Introduction
Overview
The Prisma II Reverse Video Receiver and the Prisma II Reverse Data Receiver are
part of a family of products in the Prisma II product line. These two reverse receivers
are plug-in modules for the Prisma II platform.
These products are indoor reverse receivers capable of receiving reverse path optical
signals from a reverse transmitter.
Features
The Prisma II Dual Reverse Receivers have the following features:
•Front panel green LED to indicate operating status
•Front panel red LED to indicate alarm status
•-20 dB test point
•Optical input connectors
•Plug-and-play capability
•Compatible with Cisco LCI and TNCS software
•Blind mate RF connections

78-713378-01 Rev C Introduction 1-3
Introduction,Continued
Prisma II Reverse Receiver Operation
The two reverse receivers are used in conjunction with a reverse transmitter to
receive reverse path signals to the hub or headend.
The two reverse receivers each contain two separate optoelectronic receivers. Optical
input is through two optical connectors mounted on the front of the module. The RF
output is through two connectors on the rear of the module.
In the reverse receiver, the optical signal is detected by a photodiode and is
converted to an electrical signal. The electrical signal is then sent to an RF amplifier
with approximately 24 dB of gain for the video/data module, and approximately 30
dB of gain for the data only module. The RF signal goes to its respective output
connector on the rear of the module.
Using the ICIM, LCI, or TNCS, each RF output may be attenuated as much as 20 dB
relative to no attenuation, in 0.5 dB increments. The actual RF output levels of the
dual reverse receiver (minus 20 dB) can be monitored at the two -20 dB test points on
the front panel.
The reverse receiver can be controlled by an ICIM, the LCI software, or the TNCS
software.
Optical Input
Depending on how you ordered your system, the optical input connectors may
either be an SC/APC, SC/UPC, FC/UPC, or E2000/APC.
WARNING:
Avoid damage to your eyes! Do not look into any optical connector while the
system is active. Even if the unit is off, there may still be hazardous optical
levels present.

The Front Panel
Overview
The Prisma II Reverse Receiver’s front panel is designed with two optical connectors
for optical input and two test points for RF output verification. All are easily
accessible. ALARM and Power ON indicators on the front panel allow you to
monitor power and alarm status at a glance.
The features of the front panel of the two Prisma II Reverse Receivers are shown
below.
Part Function
Alarm indicator Illuminates or blinks when an alarm condition occurs
Power indicator Illuminates when power is supplied to the module.
Optical input Connects the optical cable to the input of the reverse
receiver.
-20 dB test points Provides a –20 dB sample of the RF output signal

The Back Panel
Back Panel Connectors
Blind-mate connectors make it easy to install this module. The connector on the back
of the module mates with a connector on the inside of the chassis. The 110-pin
connector provides the following:
•Electrical power input
•Alarm communications
•Status-monitoring connections
•Communications and control connections
Power and Communications Connector
The power and communications connector on the back of the module mates with a
connector inside of the chassis, and supplies power from the chassis to the
transmitter. The 110-pin connector also routes alarm and status-monitoring
information from the receiver to the Prisma II Chassis.

78-713378-01 Rev C Introduction 1-7
Configuration Overview
Overview
The Prisma II Reverse Receivers are shipped from the factory with operational
parameters set to factory defaults. However, you will probably choose to configure
the operating parameters so that they are best suited for your application.
Configuration and Monitoring Methods
The reverse receiver may be controlled using one of three different methods.
•The Prisma II Intelligent Communications Interface Module (ICIM)
If an ICIM is installed in the Prisma II Chassis, it may be used to configure and
monitor Prisma II application modules within its domain. For instructions on
operating this module using the ICIM, refer to Chapter 3, Operation Using the
ICIM.
•The Local Craft Interface (LCI) software
The Local Craft Interface (LCI) software running on a locally connected PC may
be used to configure operating parameters of Prisma II modules. For instructions
on operating this module using the LCI software, refer to Chapter 4, Operation
Using LCI.
•Cisco’s Transmission Network Control System (TNCS) software.
If the ICIM is installed, TNCS software may be used to configure and monitor all
functions of the Prisma II modules. For instructions on operating this module
using TNCS, refer to the TNCS Administrator Software User’s Guide, part number
730201.
Configuration Summary
Using any of the above methods, you can configure the following:
•Enable or disable each receiver
•Force Mute
•Force Alarm
•Master or slave operation
•Attenuation level
For detailed information on configuring this module, see the Chapter 3, Operation
Using the ICIM, or Chapter 4, Operation Using LCI, of this guide.
