4. Introduction & Motivation 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.

5. 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.

6. Scope of the Project Scope: This project is limited to few important stages within the life cycle of a cable modem. Five Stages in CMs Initialization Sequence. Initial Ranging Phase IP Connectivity Phase TOD Phase Transfer Operational Parameters Phase Registration Phase

7. Architecture of Simulator System This slide will give the overview of simulator system.

8. 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.
