Coaxial Cable Specifications
The coaxial cable used to connect the IRIS DC1100 series universal broadband routers at the
Headend should be very high-quality cable. Coaxial recommends that you use a Headend-grade
coaxial cable or a quad-shield coaxial cable with a minimum of 60% + 40% braid and double foil
insulation to connect the cable modem cards to the HFC network. The center conductor must be
straight and extend 1/8 inch (3.2 mm) beyond the end of the connector, and the connector should
be securely crimped to the cable. The following cables are recommended:
• RG-6 — Standard 75 Ohm
• RG-6/U — Dual or Quad Shielded 75 Ohm
Note
The consistent use of RG-6 or RG-6/U cable is preferred to connect the cable interface to the
HFC network. If you connect an RG-6 cable to a cable interface that was previously connected
using RG-6 cable, the difference in the center connector diameter might cause intermittent
connectivity loss. If you use different types of coaxial cable, the following problems can appear:
ƒ
Co-channel interference—If signals at the same frequency are carried on long, parallel runs
of coaxial cable, interference can occur between the signals. Higher quality cable helps to
prevent this with better shielding. Co-channel interference is seen as hum or patterns in
analog video channels and intermittent data loss in digital channels.
ƒ
Damage to the product —Cable interface card connectors are designed for RG-6 cable and
connectors. Larger cables can damage the connectors.

Configuration
Configuring IRIS
All IRIS systems can operate in Bridge or Routing mode with NAT enabled on the cable
interface. At the time of shipping the system IRIS is configured to work in the routing mode with
NAT enabled on the cable interface.
When NAT is enabled IRIS routes packets from its cable interface to the Ethernet interface and
vice-versa. The diagram below represents the IP network topology with such configuration.
The cable interface is defined as “en1” interface and the Ethernet interface is defined as “en2”

Configuring IRIS in Router mode
All IRIS systems ship with operational mode set to “router”. In router mode the cable interface is
configured with a private interface and all cabled modems and CPEs attached to the cable
modems are automatically assigned IP addresses from this private addressing scheme.
You will need to configure the “Uplink Interface” or the Ethernet Interface with the ISP provided
configuration parameters. For the “Uplink Interface” enter the following
−
−
−
−
−
IP address
Netmask
Gateway
DNS Server
Domain Name
)
Do not change the “Cable CM Interface” or the “Cable CPE Interface” address.
Changing this will require you to edit the DHCP server configuration file manually.
You should change this address only if you wish to do so and know how to manually
program a dhcpd.conf file. Future releases of IRIS firmware will provide graphical
user interface to edit the DHCP server configuration files.
After entering these, click the “Save” button. For changes to take effect select ‘Reboot” from the
left hand side navigation bar.
Figure 11 Save and reboot
Confirm the reboot with selecting the “Reboot” button. After the reboot you should be able to
reach the “uplink” port of IRIS using the new IP address.

Configuring IRIS in Bridge mode
To configure IRIS in “bridge” mode select “Network” from the navigation menu bar. If you
configure IRIS in bridge mode, you will need to use an external provisioning server that can
provide all the required server functionality which includes DHCP server, TFTP server and TOD
server.
Figure 12 Network Setup
You will also need to configure you provisioning server so that it can allocate IP addresses to
CPE devices that are behind the cable modems. CNI provides a provisioning server called
‘XFIRE’ to achieve this functionality.
If you are planning to use multiple IRIS in your cable plant you should put IRIS in bridge mode
and use an external provisioning server. The detail setup of such a provisioning server is
beyond the scope of this document. Customers should contact CNI professional services to
get further information and training on such topics.
Click the “IRIS Mode” drop down box to select “bridge”

Figure 13 Bridge mode setup
This will change the IRIS Setup screen so that the system can be configured in the bridge mode.
In bridge mode IRIS only has one interface, which is the “cable” interface. IRIS then forward all
traffic from the HFC side to the Ethernet side.
If you are planning to use the DHCP server available on IRIS do not change “Cable CM
Interface” address. If you change this address and plan to use DHCP server on IRIS to assign IP
addresses to the cable modems make sure that the DHCP configuration file has appropriately
been updated.
Using the Alias Interface you can assign another IP address configuration to IRIS; this could be
useful if you wish to assign a public IP address to IRIS.

Configuring Downstream RF Settings
DOCSIS protocol utilizes an available channel to send downstream signal for data
communications. Depending upon the frequency plan NTSC or PAL, IRIS automatically provides
you the channel number and the center frequency in a drop down menu.
Figure 15 Downstream RF Settings
Using the “Center frequency with channel number” select the channel that you wish to use to
send downstream signal. This channel should not be used to send any video signal.
Using the “RF Power” setting you can adjust the output level of the downstream signal. If you
wish to adjust output power levels beyond the range you have to use outside attenuators. Digitally
modulated signal levels are usually 10 to 12 dB less than the analog signal levels for the adjacent
carriers.
256 and 64 QAM modulation is used for downstream communication. 256 QAM requires a much
cleaner plant and channel. For noisier cable plants it is recommended to use 64 QAM for
downstream. Using the ‘Modulation scheme’ select the appropriate downstream modulation plan.
After making the selection click the “Save” button to apply these changes. Center frequency and
RF power changes do not require system to be rebooted. Changing the downstream modulation
scheme requires a system restart.

Configuring Upstream RF Settings
DOCSIS protocol utilizes a separate upstream frequency to provide upstream data
communication back from the cable modem. Your cable plant has to be two way ready or return
passing to provide high speed data communication over cable. The North American plan uses up
to a 3.2MHz wide channel in the 5-42MHz frequency range. The European plan uses up to a 3.2
MHz wide channel in the 5-65MHz frequency range. For upstream communications DOCSIS
provide QPSK or 16QAM modulation schemes. QPSK modulation profiles are much tolerant to
noise. 16QAM modulation profiles require very clean cable plants and signal to noise ratios.
Figure 16 Upstream RF Settings
Depending upon the IRIS model you have, the Upstream RF Settings screen will have the number
of channels. For a DC1100 the screen will only have Channel 1, for DC1200 the screen will show
Channel 1 and Channel 2.
In the Frequency section for each channel type in the desired upstream center frequency you wish
to use. From the available modulation profiles select the modulation profile you wish to use.
Various modulation profiles for both 16QAM and QPSK are provided in the system.
If your system has more than one upstream channel make sure that there frequency values are
separated by a sufficient buffer or else they will interfere with each other resulting in loss of cable
modems.
After you have made the right selection, click on “Save” and the changes will apply after the
system is restarted.

Creating Class of Service Profiles
DOCSIS based data networks allow each cable modem to be associated to a class of service. This
class of service configuration is downloaded by the cable modem during registration process
using TFTP protocol.
IRIS provides a user interface using which you can enter different values for a cable modem
configuration file and then save these settings to class of service. These classes of services
profiles are then available to you in the “CM Subscription” section of IRIS configuration.
Figure 17 Class of Service Creation
When creating cable modem configuration files which specify the class of service that the cable
modem and CPEs behind them will be receiving, you can specify a different downstream channel
that the cable modem should resynchronize to after registering with this IRIS. You can also
specify which upstream channel a cable modem should register on. The Upstream channel can be
used to tie a particular class of service to a particular upstream channel. This setting is useful if
you have IRIS DC1200 or IRIS DC1400 models.
The “Net Access Enable” setting specifies if CPEs behind a cable modem configuration that
downloads this configuration file will be able to get access o the network or not.
The remaining settings specify the various parameters for class of service. Chose a “SVC Class
ID” by which you want to identify this service. This value can be any integer value and is used
for identification purposes only.
In the “MAX DS Rate…” specify the rate at which cable modems can download data. For
example if you wish to provide a 512bps data rate, you would enter 512000 in this field.
Coaxial Networks, Inc.
Page 30 of 60
Download from Www.Somanuals.com. All Manuals Search And Download.
In the “US Priority” specify the priority that you wish to assign traffic coming from this cable
modem in the upstream direction. IRIS supports 1 to 7 upstream priority classifications, 1 being
the highest.
In the “Guaranteed US Rate” specify upstream data rate which you wish to guarantee for each
cable modem. For example for voice traffic a guaranteed upstream rate of 64000 is
recommended.
In the “Configuration File name” specify the name you would wish to give this type service, for
example “business” or “residential”.
In the “Maximum CPE per Cable Modem” select the number of CPEs you wish to allow
behind the cable modem.
After entering all the values, make sure that these are the settings you wish to create this class of
service with and the click the “Generate Configuration file”
Remember that any protocol has overhead and your customers will see slightly less value if they
do a speed test. Usually the speed test program do not account for the overhead of transferring IP
packets.
In the ‘MAX US Rate…” specify the rate at which cable modems can upload data. For example
if you wish to provide a 128Kbps data rate, you would enter 128000 in this field.
IRIS implements a Class Based Queue and Round Robin allocation strategies for downstream
rate regulation. In Round Robin packets are put on a first in first out queue and as long as
bandwidth is available it will be given to the client requesting it.
If you wish to rate limit a customer to the bandwidth he is subscribed for even though there is
bandwidth available you have to enable the Class Based Queuing. By default round robin is
enabled.

Controlling Cable Modem Access
IRIS can allow all or selectively allow cable modems connected to your cable network to gain
access to the Internet.
)
By default IRIS is configured such that all modems that are connected on
your cable plant can gain access to the Internet.
To enable conditional access to certain we need to enable conditional access and then add the
MAC addresses of the cable modems. Once it has been done only cable modems with these MAC
addresses can register with IRIS. Other cable modems will not register and PCs behind these
cable modems will not be able to connect to the Internet.
Enabling conditional access
Using your browser connect to IRIS configuration interface. Select “CM Subscription” under
Advanced options.
To enable conditional access to the modems select the “Subscribe selected cable modems” and
then select “Save”. This change comes into effect after you restart IRIS.
Adding Cable Modems
After you have enabled conditional access for cable modems and restarted the system, you should
see the list of cable modems that have been subscribed. All remaining modems that have not been
subscribed but have tried to connect to the IRIS will show up in the “unsubscribed modems” list.
You can move cable modems that show up in the “unsubscribed modems” list to the “subscribed
modems” list. While subscribing modems you can assign a unit number that can be used to define

the location of each cable modem and also associate the cable modem to one of the class of
service profiles you have created. If you have not created any class of service profiles, create a
class of service using the “CM configuration” option.
A cable modem that had yet not been connected to the cable network will not show up in the
“unsubscribed modems” list. If you wish to subscribe such a cable modem before it is connected
to the cable network you should use the ‘Quick Subscription” option to enter the Mac address of
the cable modem in the show format manually and click on the “Subscribe” button.

IRIS CLI interface using Telnet
IRIS also provides a CLI interface for certain advanced configuration and diagnostics. You will
need a PC to connect using telnet. You should be able to connect to IRIS from the HFC side if
you have successfully been able to bring up a cable modem. The easiest way to connect to IRIS is
from the Ethernet interface of IRIS.
Connecting from the cable interface
If you have connected a cable modem to the cable network you can connect to IRIS using a PC
connected to the cable modem. Make sure the cable modem’s “cable” LED is steady which
indicates that the cable modem is configured correctly and is up and running. If the “cable” LED
is either off or still blinking the cable modem is not up yet, use the “Connecting from Ethernet
interface” or “Connecting using serial console” methods.
Set your PC’s Ethernet interface to be configured using dynamic host control protocol or DHCP.
As soon as your PC is connected to the Ethernet port of the cable modem it will be assigned an IP
address with the “10.71.0.X” domain.
Telnet to IRIS
You can now telnet from Windows Start Menu/Run option by typing
“telnet 10.71.0.1” and selecting OK button. You will be greeted with the following
messages and a “login” prompt in the telnet window.

Application Notes
Network traffic between cable clients
By default IRIS does not allow traffic between CPEs behind cable modems on the same IRIS. To
enable this you have to turn the “NetLoopbackMode” setting in iris.txt file to “1”.
Edit the “iris.txt” file from the system prompt and then change the above seeting to
NetLoopbackMode = 1
Save the file and restart IRIS.
Allowing PPPoE traffic across IRIS
By default IRIS is configured to forward Ethernet packets of IP protocol type only. If you wish to
offer PPPoE services to your customers, you have to configure IRIS so that PPPoE protocol is
forwarded across IRIS. This configuration applies if you are operating IRIS in bridge mode.
Edit the “iris.txt” file from the system prompt and then under the
“BEGIN_NetProtocolType“ section add the following lines which specify the PPPoE
Ethernet packet type
BEGIN_NetProtocolType
TypeField1 = 0x81
TypeField2 = 0
TypeLength = 1
END_NetProtocolType
Make sure you do not remove the default forwading for IP Ethernet packet types.
BEGIN_NetProtocolType
TypeField1 = 8
TypeField2 = 0
TypeLength = 1
END_NetProtocolType
// default = 8 (IP)
// default = 0 (ALL)
// default = 1
Save the file and restart IRIS.
Static IP Mapping
When IRIS is operating in Router mode, some ISPs will like to reserve a publicly routable IP
address for a specific CPE behind the Network Address translation. Using this feature IRIS will
then create a one to one mapping between the public IP address and the private IP address. This
feature of NAT is called BIMAP.
Coaxial Networks, Inc.
Page 43 of 60
Download from Www.Somanuals.com. All Manuals Search And Download.
To create a BIMAP you will need to know the MAC address of the CPE. To obtain this you can
Telnet to IRIS and issue the "pcpe" command find the cable modem that the end user has,
attached you will see his CPE Mac address.
Assigning a reserved IP address to the CPE.
Edit the /etc/dhcpd.conf file and add a "host" entry for the MAC address of the CPE with a
Reserved IP address in the "#CPE Network" subnet
host user1 {
hardware ethernet 00:12:17:4C:9b:21;
fixed-address 10.71.0.2 ;
}
Save the file and restart the DHCP server using the following commands
# slay -f dhcpd <ENTER>
# dhcpd en1 <ENTER>
Assigning additional IP addresses to the uplink Interface
From system prompt edit the "netstart.user" file and add the following line
/usr/ucb/ifconfig en2 alias <ip-address> netmask <netmask>
Make sure you put the <ip-address> and <netmask> that you have from your service
provider.
This command will configure IRIS "en2" or uplink interface with an additional IP address that
will be used to create a BIMAP. Save the file and exit to system prompt.
Creating a BIMAP between the public IP address and the private IP address
From system prompt edit the startnat file and at the end of the line before the
"EOF" command
bimap en2 <internal-ip-address>/32 -> <public-ip-address>/32
Replace <internal-ip-address> with the internal IP address that you have reserved in the
dhcpd.conf file in step 1. Replace <public-ip-address> with the external Ip address that was
assigned to the en2 port in step 2. Save the file and exit to system prompt. Restart the system to
make the changes.

VI (Visual) Editor
The vi is a text editor. It is small, powerful, and standard on most UNIX systems. The vi often
frustrates new users with a unique distinction between its two modes: Command Mode and
Insert/Overtype Mode. This distinction, although difficult to become accustomed to for many
users, provides great power and ability to the editor. Insert/Overtype Mode is designed for
inserting text only. All text manipulations and cursor moving should be done from with in
Command Mode.
Entering the vi
# vi
# vi file1 file2 ...
# vi -r file #Recover file from crash
# vi +string file #Execute ex command "string"
# vi @rcfile #Read commands from rcfile
Insert/Overtype Mode
Insert/Overtype Mode is solely for entering text. To leave one of these two modes press the
[ESC]key. if you wish to enter the ESCcharacter or any other control character while in insert
mode: type [CONTROL]-Vand then the control sequence. The only difference between Insert
Mode and Overtype Mode is that characters are placed in front of the text after the cursor in Insert
Mode; where as existing characters are overwritten in Overtype Mode.
Command Mode
Entering Insert Mode
ƒ a -- append text, after the cursor
ƒ i -- insert text, before the cursor
ƒ R -- enter Overtype Mode
ƒ A -- append text, after end of line
ƒ I -- insert text, before first non-whitespace character
ƒ o -- open new line below cursor in Insert Mode
ƒ O -- open new line above cursor in Insert Mode
vi Syntax
vi commands follow the general form:
n operatorm object
which means:

execute operatorn times on m objects.
If n and/or m are omitted,
they default to 1. Operators which take objects are(if the operator is pressed
twice then the object is the current line)
ƒ c-- Change
ƒ d-- Deletion
ƒ "cy-- Yank, if "c is omitted, uses general buffer.
ƒ <-- shift lines left by shiftwidth variable
ƒ >-- shift lines right by shiftwidth variable
ƒ !cmd -- filter trough cmd
The operators <, >, and ! are line based so the set
of objects is diminished greatly.
Operators, which do not take objects:
ƒ s-- Substitute
ƒ x-- Delete character
ƒ r-- Replace character
ƒ ~-- change case of character
Objects (if given with out an operator are interpreted as a cursor motion
command):
ƒ w-- forward until beginning of word
ƒ e-- forward until end of word
ƒ b-- backward until beginning of word
ƒ $-- forward until end of line
ƒ ^-- backward until first non-whitespace character
ƒ 0-- backward until first column of line
ƒ nG-- line number n
ƒ n|-- column n of current line
ƒ /pat -- forward until beginning of pat, search
ƒ ?pat -- backward until beginning of pat, backward search
ƒ n-- repeat last search
ƒ N-- repeat last search/backward search, but in opposite direction
ƒ %-- until match of parenthesis, brace, or bracket
ƒ tc -- until next appearance of c on current line
ƒ Tc -- backward until next appearance of c on current line
ƒ fc -- until and including next appearance of c on current line

ƒ Fc -- backward until and including next appearance of c on current
line
ƒ ;-- repeat last f, F, t, or T
ƒ , -- repeat last f, F, t, or T in reverse
ƒ }-- forward until end of paragraph
ƒ {-- backward until end of paragraph
ƒ )-- forward until end of sentence
ƒ (-- backward until end of sentence
ƒ ]]-- forward until end of section
ƒ [[-- backward until end of section
ƒ nH-- n lines before first line on screen; n defaults to 0
ƒ nL-- n lines before last line on screen; n defaults to 0
ƒ M-- the middle line of the screen
ƒ j-- down one line
ƒ k-- up one line
ƒ h-- left one character
ƒ l-- right one character
ƒ [BS]-- left one character, backspace usually equals ^H
ƒ [SPACE]-- right one character
ƒ _-- the entire current line
ƒ --- until first non-whitespace character on previous line
ƒ +-- until first non-whitespace character on next line
ƒ [RETURN]-- until first non-whitespace character on next line
Miscellaneous 1
ƒ u-- undo last change
ƒ U-- undo entire line
ƒ "cp-- put "c or general buffer after the cursor
ƒ "cP-- put "c or general buffer before the cursor
ƒ mc -- set mark with character c
ƒ `c -- goto mark c
ƒ 'c -- goto beginning of line with mark c
ƒ ``-- return to position before mark jump or search
ƒ ''-- return to beginning of line before mark jump or search
ƒ J-- join two lines
ƒ D-- delete rest of line
ƒ C-- change rest of line
ƒ Y-- yank current line into general buffer

ƒ &-- execute last ex-style substitution
ƒ . -- execute last modification
ƒ !object command -- send object as stdin to command and replace with
stdout
ƒ [Ctrl]-G-- print information about file
ƒ : mapx y -- when character x is pressed, execute y
ƒ : map!x y -- map input mode character x to string y
ƒ : abx y -- x is an abbreviation for y, changes are made on the fly
ƒ : su-- Suspend the current editor session
ƒ : sh-- run a shell
ƒ
ex Commands
ex syntax
ex commands in the vi follow this general form:
: Addresscommand
Which means:
Execute command on specific lines obtained from the addresspart of the general form.
If addressis omitted, current line is used. Keep in mind that the ex is a line-based editor; so all
actions are line based.
Addresses:
ƒ % -- all lines in file
ƒ x,y -- lines x to y
ƒ . -- current line
ƒ n -- line number: n
ƒ $ -- last line of file
ƒ x-n -- n lines before line x
ƒ x+n -- n lines after line x
ƒ /pat/ -- forward to line containing pat
ƒ ?pat? -- backward to line containing pat
Some commands are:
ƒ s/pat/text/ -- substitute 1st match of pat with text
ƒ s/pat/text/g -- substitute every match of pat with text
ƒ s/pat/text/n -- substitute the nth occurrence of pat with text
ƒ ya c -- yank into buffer c or the general buffer if c is omitted
ƒ g address cmd -- execute cmd on all lines which satisfy address
ƒ > -- shift right
ƒ < -- shift left
ƒ d -- delete line
ƒ ! UNIX-cmd -- execute UNIX-cmd on line
ƒ m address -- move lines to address

You can customize your environment with this command by typing set var=value,
this will set the specified varto valuefor a scalar variable. For Boolean variables, use
set varto set and set novarto unset. You can see which variables are set by just
typing the setby itsself. You can see a list of all variables by typing set all. Some
environment variables are specific to the ex editor and some are specific to the vi editor. I
have included both.
Boolean variables:
ƒ autoindent(ai) -- begin editing next line at same level of
indent-ion as this one.
ƒ autowrite(aw) -- write current buffer before leaving

current directory.

incorrect

the visual cursor to opening item to check scope
