Theory of Operation
This section summarizes the theory of operation for cable modem gateways and
provides a high-level overview of the operational stages for the cable modem
gateway. Reading this chapter provides a better understanding of how cable modem
gateways operate.
Note: This section is not intended to be a specification for the cable modem gateway.
Cable Modem Initialization
A cable modem gateway must establish a communication link with the headend
before it becomes fully operational. This section describes the eight DOCSISrequired operational stages through which a cable modem gateway progresses in
establishing this communication link.
This section provides a detailed explanation of each of the following operational
stages.
1 Scan for Downstream Channel
2 Obtain Upstream Parameters
3 Adjust Timing Offset and Power Level
4 Establish IP Connectivity
5 Establish Time of Day
6 Transfer Operational Parameters
7 Register with the Cable Modem Termination System (CMTS)
8 Initialize Baseline Privacy
Scan for Downstream Channel
When a cable modem gateway powers on, the cable modem gateway starts to scan
the network for the CMTS downstream channel. The downstream channel is the
channel used to send data from the CMTS to the cable modem gateway. The cable
modem gateway identifies a valid downstream data channel as a channel that has
QAM signal timing, forward error correction (FEC) framing, MPEG packets, and
downstream media access control (MAC) messages. The CMTS terminates the cable
modem gateway signal at an upstream location and provides the cable modem
gateway with a network connection.
This section discusses the cable modem gateway downstream scanning routine
along with two features that speed up the downstream scanning process: the Valid
CMTS Frequency Table and the WebWizard Gscan function.
Theory of Operation
68-4004214-01 Rev D 9
Downstream Scanning Routi ne
The cable modem gateway starts its own standard scanning algorithm. The scanning
routine of the cable modem gateway is now optimized to seek out the CMTS
downstream channel as quickly as possible. The actual scanning process varies
slightly depending on the television frequency channel plan for your particular
country.
For example, in North America the standard downstream scanning routine works in
three phases and may take several minutes. The cable modem gateway stops
scanning when the cable modem gateway finds a valid downstream data channel.
The cable modem gateway then proceeds to the next stage: obtain upstream
parameters.
In this example, the cable modem gateway scans for the downstream channel in the
following three phases.
1 The cable modem gateway starts to scan the network at 453 MHz and scans up in
6 MHz increments to end at 855 MHz.
2 The cable modem gateway starts scanning the network at 447 MHz and then
scans in 6 MHz increments down to 93 MHz.
3 The process is then repeated for the National Television Systems Committee
(NTSC) Harmonic Related Carrier (HRC) frequency plan in 6.0003 MHz
increments.
Important: There are specialized frequency plans to optimize the acquisition of the
downstream signal that depend on the video format used in the country of
deployment. Check with the representative who handles your account for more
information about alternate scanning routines outside of North America.
Improved Downstream Scann ing Features
The cable modem gateways contain two outstanding features that can speed up the
scanning process: the Valid CMTS Frequency Table and the WebWizard Gscan
function.
Valid CMTS Frequency Table
The Valid CMTS Frequency Table feature works automatically and requires no user
intervention. When a cable modem gateway finds a valid downstream data channel
so that it can complete the ranging stage, the cable modem gateway stores this
frequency in nonvolatile memory (NVM). The cable modem gateway checks the
frequencies stored in NVM before starting the standard scanning algorithm to search
for a downstream data channel.
Note: The cable modem gateways store up to 10 valid CMTS frequencies in the table.
The standard scanning algorithm also regularly interrupts progressive scanning to
check the last known valid CMTS frequency, and then the cable modem gateway
resumes its standard scanning algorithm where it left off.
Chapter 1 Introducing the Model DPR2320, DPR2325, EPR2320, and EPR2325 Cable Modem Gateways
10 68-4004214-01 Rev D
WebWizard Gscan Function
When installing a cable modem gateway, you can speed up the process by using the
WebWizard Gscan function. To access the WebWizard Gscan function, you must
first connect a PC to the cable modem. Then, using your Web Browser, you can
access the WebWizard Gscan function.
Note: For more information on the WebWizard Gscan function, see WebWizard
(on page 106).
Obtain Upstream Parameters
After finding a valid downstream data channel, the cable modem gateway reviews
the upstream parameters needed to perform the next stage: ranging and automatic
adjustments. The upstream parameters enable the cable modem gateway to send
data to the CMTS. When the cable modem gateway finds the correct upstream
parameters, the cable modem gateway proceeds to the ranging and automatic
adjustments stage.
If the cable modem gateway cannot find valid upstream parameters, it returns to the
scan for downstream channel stage. Then the cable modem gateway starts to scan
again at the next available channel.
Adjust Timing Offset and Power Level
After the cable modem gateway obtains its upstream parameters, it begins the
ranging and automatic adjustments stage. In this stage, the cable modem gateway
adjusts the timing offset and the power level for communicating with the CMTS.
The cable modem gateway uses MAC messages to determine the upstream channel
frequency and adjusts timing offsets to verify the synchronized timing between the
CMTS and the cable modem gateway. This process also determines the upstream
signal transmit power level from the cable modem gateway to communicate with the
CMTS.
After the cable modem gateway completes the ranging stage and registers with the
CMTS, it repeats this routine regularly to fine-tune the settings established in the
previous stages. These regular adjustments are considered routine maintenance and
do not affect normal operations of your cable modem gateway service.
Note: If the cable modem gateway fails to achieve the proper settings when
performing ranging and automatic adjustments, it terminates the session and restarts
the initialization process at the scan for downstream channel stage.
Theory of Operation
68-4004214-01 Rev D 11
Establish IP Connectivity
After completing the ranging and automatic adjustments stage, the cable modem
gateway attempts to establish Internet Protocol (IP) connectivity. In this stage, the
cable modem gateway obtains network connection information and a cable modem
gateway IP address from provisioning servers that are located on the network side of
the CMTS interface.
The cable modem gateway achieves this connectivity using a protocol called
Dynamic Host Configuration Protocol (DHCP).
Note: If the cable modem gateway fails to establish IP connectivity, it terminates the
session and restarts the initialization process at the scan for downstream channel
stage.
Establish Time of Day
After the cable modem gateway establishes IP connectivity, the cable modem
gateway requests the time of day from the network interface. This stage allows the
cable modem gateway to know the system time so that when the cable modem
gateway logs an event, it associates a time with that event.
Note: The cable modem gateway can operate without establishing the time of day;
however, it logs the failure, generates an alert to simple network management
protocol (SNMP), and then proceeds to the next stage. The cable modem gateway
periodically repeats this stage to attempt to establish the time of day.
Tr ansfer Operational Parameters
After the cable modem gateway requests the time of day, the cable modem gateway
then requests the transfer of the cable modem gateway configuration file. The cable
modem gateway makes the request to the Trivial File Transfer Protocol (TFTP)
server. The configuration file contains parameters for how the system operator
wants the cable modem gateway to function on the cable network.
Typical operation parameters for the cable modem gateway include:
Upstream and downstream rate limits
Specific frequencies
Number of CPE devices
IP filters
Port filters
MAC/LLC filters
Vendor-specific settings
Software version installed
Chapter 1 Introducing the Model DPR2320, DPR2325, EPR2320, and EPR2325 Cable Modem Gateways
12 68-4004214-01 Rev D
Notes:
If the cable modem gateway does not contain the software version requested by
the configuration file, the cable modem gateway requests that software version
from the TFTP server. When the software installation is complete, the cable
modem gateway restarts the entire initialization process again at the scan for
downstream channel stage.
If the system instructs the cable modem gateway to use a different frequency
from what the cable modem gateway is currently using, the cable modem
gateway cannot proceed to the next stage: register with the CMTS. The cable
modem gateway must repeat the scan for downstream channel stage or
reestablish ranging on a new upstream channel.
Register with the CMTS
After the cable modem gateway completes the transfer operational parameters stage,
the cable modem gateway now registers with the CMTS. After the cable modem
gateway receives a reply from the CMTS confirming its registration request, the
cable modem gateway is now authorized to forward network traffic from the CPE.
Initialize Baseline Privacy
Baseline Privacy functions in the CMTS and in the cable modem gateway are used to
encrypt data being transferred to and from the cable modem gateway. Following
registration with the CMTS, if the cable modem gateway is provisioned to run with
baseline privacy, the cable modem gateway must initialize baseline privacy
operations. Using baseline privacy means that all data transferred is secure.

Setup Advanced Settings - Port Forwarding Page Description
The following example illustrates how to use the port forwarding feature to
configure the Microsoft X-Box Online Live for Internet gaming.
Note: For most widely used applications (including Microsoft X-Box Online Live),
the built-in firewall automatically maps and opens ports required for that
application while the application is in use.
1.
Set the device to be used for port forward to a fixed IP address, for
example, 192.168.0.5.
2.
In the first entry of the Port Forwarding area of the page, enter the
same IP address (192.168.0.5) in the Local IP Address field.
3.
In the same row, enter the appropriate port numbers in the Start
Port and End Port fields.
4.
In the same row, select the appropriate protocol from the dropdown list in the Protocol field, and then select the box in the
Enable field.
5.
To add additional ports, repeat steps 1 through 4, and then go to
step 6.
6. Click Apply to apply and save your new port forwarding settings.
Configuring TCP/UDP Port Triggers
Use the Setup Advanced Settings - Port Triggers page to configure TCP/UDP port
triggers. Port triggering is similar to port forwarding but is dynamic. In other words,
the system does not hold the ports open indefinitely. For example, when the cable
modem gateway detects outgoing data on a specific IP port number set in the
“Trigger Range,” the resulting ports set in the “Target Range” opens for incoming
data. If the system detects no outgoing traffic on the “Trigger Range” ports for a
period of 10 minutes, the “Target Range” ports close. This is a safer method for
opening specific ports for special applications, such as video conferencing programs,
interactive gaming, and file transfer in chat programs. This is safe because the ports
are dynamically triggered and not held open continuously or left open erroneously
by the router administrator. Therefore, these ports are not exposed and are not
vulnerable for potential hackers to discover.
Note: If you are not familiar with the advanced settings detailed in this section,
contact your service provider before you attempt to change any of the cable modem
gateway default advanced port triggers settings.

Configuring the DMZ Host
Use the Setup Advanced Settings - DMZ Host page to configure an IP address that is
visible to the WAN. DMZ hosting is commonly referred to as “exposed host.” DMZ
hosting allows you to specify the “default” recipient of WAN traffic that Network
Address Translation (NAT) is unable to translate to a known local PC. DMZ allows
one IP address to be unprotected while others remain protected.
Note: If you are not familiar with the advanced settings detailed in this section,
contact your service provider before you attempt to change any of the cable modem
gateway default advanced DMZ host settings.

Use this page to place a Private LAN IP device; for example, an FTP, Mail, or Web
server directly on the Internet (bypassing the firewall). You set the server with a
fixed IP address as a DMZ Host by entering its IP address in the DMZ Address field.
Make sure the IP address used is not in the range of addresses delivered by the builtin DHCP server. After setting up a DMZ Host, all ports on this device are open to
the Internet. You may configure only one PC to be the DMZ host. DMZ is generally
used for PCs running “problem” applications that use random port numbers and do
not function correctly with the specific port triggers or port forwarding setups
described earlier in this guide. After entering a DMZ Address, click Apply to apply
and save your new DMZ Host setting.

Configuring VPN Termination
Use the Setup Advanced Settings - VPN Termination page to configure VPN
protocols and manage VPN tunnels. A VPN is a connection between two endpoints
in different networks that allows private data to be sent securely and transparently
over public networks or other private networks. With a VPN, you can send data
securely between these two locations or networks. This is accomplished by creating a
“VPN tunnel.” A VPN tunnel connects the two PCs or networks and allows data to
be transmitted over the Internet as if it were still within those networks. The VPN
tunnel uses IPsec (Internet Protocol security) to encrypt the data sent between the
two networks and encapsulate the data within a normal Ethernet/IP frame so as to
transport the private network securely and seamlessly through other public or
private networks.
A VPN provides a cost-effective and more secure alternative to using a private,
dedicated, leased line for a private network. Using industry standard encryption and
authentication techniques, an Internet Protocol Security (IPsec) VPN creates a secure
connection that operates as if you were directly connected to your local network.
For example, a VPN allows users to sit at home and connect to his/her employer's
corporate network and receive an IP address in their private network just as though
they were sitting in their office connected to their corporate LAN.

IPsec settings Section
With VPN tunnels there are two phases of Security Association (SA).
Phase 1 creates an Internet Key Exchange (IKE) SA
When Phase 1 is complete, Phase 2 creates one or more IPsec SAs that are then
used to key IPsec sessions
Field Description
Pre-shared key Allows you to enter the Pre-shared key of the firewall identifier if one
side of the VPN tunnel is using a unique firewall
Phase 1 DH group Allows you to select one of following three Diffie-Hellman (DH)
encryption/decryption groups:
768 bits
1024 bits
1536 bits
Diffie-Hellman is a cryptographic technique that uses public and
private keys for encryption and decryption. The higher number of bits
selected, the more secure the connection
Phase 1 encryption Allows you to select the form of encryption to secure the VPN
connection between endpoints. Select from the following five
encryption types:
DES
3DES
AES-128
AES-192
AES-256
You may choose any encryption type as long as the other end of the
VPN tunnel uses the same method
Phase 1 authentication Allows you to select an authentication type for another level of
security. Select one of the following authentication types:
MD5
SHA
You may choose either authentication type as long as the other end of
the VPN tunnel uses the same method
Note: SHA is recommended because it is more secure.

Field Description
Phase 1 SA lifetime Allows you to enter the number of seconds for an individual rotating
key to last until a re-key negotiation between each endpoint occurs.
Smaller lifetimes are generally more secure since it would give a hacker
a smaller amount of time to try to crack the key. However, key
negotiation does take up bandwidth, so network throughput is
sacrificed with small lifetimes. The default setting is 28,800 seconds
Phase 2 encryption Allows you to select the form of encryption to secure the VPN
connection between endpoints. Select from the following five
encryption types:
DES
3DES
AES-128
AES-192
AES-256
You may select any form of encryption as long as long as the other end
of the VPN tunnel uses the same method
Note: 3DES encryption is commonly used, but AES is recommended
because it is very difficult to crack.
Phase 2 authentication Allows you to select an authentication type for another level of
security. Select one of the following three authentication types:
MD5
SHA
Null (none)
You may choose any authentication type as long as the other end of the
VPN tunnel uses the same method
Note: SHA is recommended because it is more secure.
Phase 2 SA lifetime Allows you to enter the number of seconds for an individual rotating
key to last until a re-key negotiation between each endpoint occurs.
Smaller lifetimes are generally more secure since it would give a hacker
a smaller amount of time to try to crack the key. However, key
negotiation does take up bandwidth, so network throughput is
sacrificed with small lifetimes. The default setting for Phase 2 is 3,600
seconds.

Introduction
We use computers for everything from banking and investing to
shopping and communicating with others through email or chat
programs. Although you may not consider your communications “top
secret,” you probably do not want strangers reading your email, using
your computer to attack other systems, sending forged email from
your computer, or examining personal information stored on your
computer (such as financial statements).
Security is the process of preventing and detecting unauthorized use
of your computer. Prevention measures help you to stop unauthorized
users (also known as “intruders”) from accessing any part of your
computer system. Detection helps you to determine whether or not
someone attempted to break into your system, if they were successful,
and what they may have done.
Use the WebWizard pages in this chapter to set up security on your
system by configuring webpage filtering and firewall protection.
These pages allow you to enable various firewall protection filters.
