Configuring the DHCP Server and 
QPSK Modulator for an FTTP 
System Installation Instructions 

Cable service providers have searched for a cost effective way to provide very 

high-speed broadband access and triple-play services (voice, video, and data) to 

residential and small business communities for decades. Fiber-to-the-Premises 

(FTTP) is the answer. Deploying FTTP will help to eliminate the bandwidth 

limitations of deployed copper in the loop and surpass the capacity of the current 

broadband access alternatives. 
This document describes the requirements for Cisco systems software operating 

in an FTTP environment. In this case, systems software includes the System 

Release (SR), Operating System (OS), and Cisco Resident Application (SARA). 
To help you understand an FTTP system, this document compares the HFC 

architecture to the FTTP architecture. For step-by-step instructions, this document 

focuses only on configuring the Quadrature Phase-Shift Keying (QPSK) 

modulator and the third-party Dynamic Host Configuration Protocol (DHCP) 

server required to support an FTTP system. Instructions are also provided for 

enabling DAVIC Express as the Digital Home Communications Terminal (DHCT) 

Communication Mode (DCM) for the QPSK modulator. 

 

This document provides the software and hardware requirements for 

implementing FTTP as well as the required system settings. Instructions for 

configuring the QPSK modulator and DHCP server are provided. 

 
 

This document is intended for system operators of the Cisco Digital Broadband 

Delivery System (DBDS) who use SARA and want to implement an FTTP system. 

Cisco field service engineers who help system operators manage their systems 

will also find the contents of this technical bulletin useful.
