Motivation and force behind the project.
This project provides an overview into the
lifecycle of a cable modem.
Cable modem uses DOCSIS protocol to transmit &
receive packets from CMTS.
This project discusses the methods of communication
between cable modem and CMTS.
Objective of the Project


In this project I will be working/developing on Initial
Ranging Phase & Transfer Operational Parameters
phases of the cable modem.
After successfully developing both the phases, I will
be able to provide insights in both the phases and
will be able to understand the role of DOCSIS v3.0
in modern CMs.
Scope of the Project

Scope:
 This
project is limited to few important stages within the
life cycle of a cable modem.
 Five Stages in CM’s Initialization Sequence.
 Initial
Ranging Phase
 IP Connectivity Phase
 TOD Phase
 Transfer Operational Parameters Phase
 Registration Phase

Methodology & Achievements


Review the literature on DOCSIS Mulpi v3.0.
Phase 1:
Development of Initial Ranging Phase.
 Outcome & Achievement: Cable modem & CMTS will be
able to communication with each other.


Phase 2:
Development of the TFTP Phase.
 Outcome & Achievement: Connectivity between cable
modem and TFTP server. After the completion of this phase
cable modem will go in ONLINE state and will be ready to
transmit and receive data packets.
