Introduction
Coaxial Networks provides an integrated solution to the hospitality businesses, apartment
complexes and broadband service providers for deploying Internet services. The solution is
geared towards cutting down challenges such as cost and rack space faced by the hotel operators.
IRIS DC1100 is a very compact and cost effective solution. Using IRIS, Network or System
Integrators can deploy blazing fast Internet over existing coax and cable TV infrastructure. The
system comprises of all the hardware and software elements tied together to provide one
comprehensive solution. Utilizing the existing cable infrastructure, which means no costly
rewiring or downtime; operators can quickly deploy these services.
The core elements of the system are DOCSIS 1.0/1.1 compatible hardware system, auto
provisioning of subscribers and services, bandwidth and policy management. Coaxial Networks
provides the complete solution including the CMTS, Software and Cable Modems. The
comprehensive package enables the service providers to roll out services in the untapped
hospitality, MDU and MTU markets.
Key Benefits
No New Wiring
IRIS DC1100 utilizes the existing cable infrastructure, which means no new costly rewiring. The
system can be deployed without any downtime so crucial for the hospitality business.
Single Server Broadband Solution
IRIS DC1100 is a single server broadband solution, with which you can deploy and manage your
broadband IP network. All the required services such as DHCP, NAT, Firewall (IP Filtering) are
integrated in the IRIS DC1100. Each receive channel of IRIS is geared towards provisioning 250
cable modems. Actual network planning is required to determine how many subscriber cable
modems you should put on each receive channel.

IRIS DC1100 provides remote administration using the Web (HTTP). A command line interface
is provided for users wishing to use the advanced features through Telnet or Serial port. The
system can be monitored and configured using SNMP.
Standards Based
IRIS DC1100 utilizes the DOCSIS based standards and protocols. You will not be dealing with
any proprietary solution. DOCSIS standard was created to enable data over the cable TV so that
both data and video can coexist on the same coax cable.

2. Intake openings for the system cooling fans for the IRIS chassis
Both Front panel and rear panel have vents for system fan, care should be taken that these vents
are not blocked during installation.
Mounting the IRIS Unit
The IRIS system can be mounted on a 19” Floor mounted Rack or 19” Wall Mount Rack with
other equipment. In the absence of a 19” rack, you can mount the IRIS unit flat on the wall with
the same mounting brackets supplied with the unit. The screws are provided to attach these braces
to the chassis. However you will need to provide appropriate screws to secure the chassis to the
wall. If you have a dry wall, recommended screws are hollow wall anchor screws. Always check
your local code for compliance.
Mounting on standard 19” Rack with IRIS connectors in the Front
Use the supplied screws to attach the mounting brackets to the sides of the unit in the front for
mounting IRIS on a 19” rack. Your rack supplier usually supplies the screws required for
mounting.
Mounting on standard 19” Rack with IRIS connectors in the Rear
Use the supplied screws to attach the mounting brackets to the sides of the unit in the rear for
mounting IRIS on a 19” rack. Your rack supplier usually supplies the screws required for
mounting.

Mounting Flat on Wall
To mount the IRIS chassis for flat wall mount use the supplied rack mounting braces and attach
them to the holes in the middle of chassis using the same screws.

Setup
Connecting Your IRIS DC1100
1. Place your IRIS DC1100 in a location where it will be well ventilated. Do not stack it
with other devices or place it on carpet.
2. Connect your WAN equipment Ethernet port with CAT5 cross over cable to IRIS
DC1100 Ethernet Port. If connecting to a hub or switch use a CAT5 straight through
cable.
3. For coaxial connections determine the model number of the IRIS unit.
The following models come with integrated fully agile 256 QAM DOCSIS Upconverter.
DC1100/DC1200/DC1400
The following models do not include an integrated upconverter.
DC1100X/DC1200X/DC1400X
You will have to connect the IF out from IRIS to a 256 QAM DOCSIS upconverter,
before cable modems will be able to connect to IRIS.
Refer to the chapter 3 for diagrams detailing these connections.
Checking Conditions Prior to System Startup
Check the following conditions before you start your gateway:
All network interface cables are connected.
The power cable is connected and secured.
The console terminal is connected and powered on.
Starting the System
After installing the IRIS gateway and connecting cables, start the router as follows:
Insert the power cable at the rear of the IRIS chassis. The green Power LED on the rear
panel will light up.
Listen for the fans; you should immediately hear them operating.

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:
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.
Damage to the product —Cable interface card connectors are designed for RG-6 cable and
connectors. Larger cables can damage the connectors.
