MATLAB DOCSIS Bonded Simulation
 The MATLAB® Simulink simulation represents a DOCSIS cable modem
transmitting with four bonded upstreams at 16‐QAM, 2560 kSym/sec (3.2
MHz).
 The cable modem has been modeled against the DOCSIS 3.0
specification, including:
 • Reed Solomon Encoder • Byte Interleaver • Scrambler • Preamble
Prepend (QPSK 0/1) • Grey Symbol Mapper • Root‐Raised Cosine Filter
 The Volpe Firm is not only an expert on MATLAB modeling, but is also an
expert within the telecommunications industry. This means we
understand the problems you and your customers are faced with and can
then simulate them in a numerical modeling environment. Intelligent
design!

PNM Technology Experts
 DOCSIS Proactive Network Maintenance (PNM)
developed by InGeNeOs™ under Cablelabs® -The Volpe
Firm is a contributing member
 The summary being a drastic reduction in maintenance
costs and significantly improved operational efficiencies
 Identifying impairments in their cable plant FAST
 Pinpoint the location on a map
 Lowered maintenance costs for the cable operator and
better cable video and high-speed data service for
subscribers

The Volpe Firm are experts in understanding and improving DOCSIS security
We can work with your existing staff to make recommendations
Assess your current security strengths, weaknesses, opportunities and threats
(SWOT)
Develop a full top down security approach and infrastructure and implement

Or a combination of all of the above
 The Volpe Firm also has a long history in DOCSIS Protocol and Capacity Assessment
dating back to the first release of CableLab’s “Network Dimensioning Software”
tool.

Remote System Audit
 Access to superior broadband troubleshooting isn’t as hard to come by as
you might think. Several of our clients within the US and internationally
have us audit their systems remotely.
 Broadband, Internet, Data Audits, CMTS & Cable Modem Configuration
files & Optimization Services How does it work? You send us the files
and we analyze them. Upon completion of our analyses we will send you
recommendations and advise you of your next steps to address your
DOCSIS plants issues. It’s that easy. Get fast results that save you
money and increase customer satisfaction.
 We are experts in CMTS and cable modem configuration files. We will
provide you with CMTS commands that will enable you to create log files
and will give us significant insight into the health of your overall physical
DOCSIS plant. With this information we help our clients by providing
them with strategic and tactical recommendations on how to improve
the health of their plant. We are competitively priced and have the
technical knowledge of the big players.

On Site System Audit
 On a Site System Audit The Volpe Firm Inc. will evaluate and test
the RF alignment of a headend. These tests should identify any
RF impairments or RF alignment issues within
headend, CMTS, EQAMs, modulators, headend
amplifiers, splitting and combining network, cables and
connectors. Spot checks of the plant should also be performed to
ensure the plant is correctly aligned with elements in the
headend on both the forward and return.
 Parameters such as RF levels, MER, CNR, constellation
diagrams, Pre and post Block Errors, group delay, in channel
frequency respond, response across all downstream and
upstream DOCSIS carriers, upstream band-edge roll
off, ingress, noise, impulse noise, CPD, non-linear distortions and
laser clipping should be investigated and identified. The plant
should be qualified for DOCSIS and industry specifications where
possible and practical.

10. High Level Architecture Design
10
 DOCSIS and CMTS Architectural Configuration
 CMTS configuration parameters that impact revenue services are often difficult to
understand – we add clarity
 VoIP Configuration
 Make sure you are providing the best VoIP services to your subscribers and the
maximum Erlang capacity
 Physical and Data Layer Troubleshooting
 Often the most time consuming and painful to your subscribers, we understand
troubleshooting like no one else
 DOCSIS BPI+ and IP Security
 Today our DOCSIS networks are inherently insecure and many are unaware of
this. They are open to theft of service, illegal intercept of the data
transmitted, illegal wiretapping of phone calls, etc. Even with Baseline Privacy
Interface Specification (BPI+) DOCSIS is quite hackable as evidenced on a number
of well-known hacking sites.
 Capacity Planning
 The goal of capacity planning is to identify the amount of resources required to
meet service demands now and in the future. It is a proactive discipline with farreaching impact
