1 Introduction
1.1 The In:xtnd™ System
InCoax™ is a provider of broadband access solutions leveraging existing in-building coaxial cable networks. The
In:xtnd System consists of a Management System (In:xtnd™ | Manage) which manages
Controllers (In:xtnd™ |
Control) installed in, or near, buildings and Modems (In:xtnd™ | Access ) installed in customers’ homes. An
illustration of the management system can be seen in Figure 1 . The Modem is easily installed by the customers
without any requirements for configuration. This architecture makes the system very flexible. Once the
Controller has been installed in, or near, the building the only required operation to connect new customers is
to provide them with a Modem . As soon as the Modem has been connected to the coax network, it will
automatically be detected and properly configured by the Controller through the Management System.
The typical In:xtnd System consists of one Management System which handles hundreds of Controllers and
thousands of Modems . If there is a legacy cable-TV service in the building the TV signal can be multiplexed with
the broadband signal using the Diplexer (In:xtnd™ | Combine). The Management System is used as a customer
configuration, monitoring, and provisioning tool through a web interface. In larger networks the
Controller
functions used by the Management System can be accessed by any other provisioning system or Operating
Support System through a SOAP/XML interface.

— Overview of the Management System.
1.2 The In:xtnd™ | Manage | MA2.5
The Management System is a software package installed in a Linux environment. It manages the Controllers
and Modems . The Management System automatically detects new Modems and manages the mapping of
subscriber data. It also collects and presents communication statistics parameters and priorities. Furthermore,
it measures and presents the RF link quality in real time and handles various alarms to the operator.
1.3 The In:xtnd™ | Control | MA2.5 | 4
The Controller acts as a bridge between the Ethernet access network and customers’ local area Ethernet, using
the in-building coaxial network as transport for data traffic to the Modems . The Controller communicates with
all Modems , over dedicated RF channels, in the coaxial network to manage their individual configuration,
enforces traffic, and security policies. It also collects and stores traffic statistics data from the network.
1.4 The In:xtnd™ | Access | MA2.5 | 2
The Access Modem is an Ethernet network terminal. It connects to any antenna outlet in the subscribers’
homes for easy self-installation. It communicates with the Controller to get configuration parameters and
connects to the subscribers’ local area Ethernet (e.g. usually a residential gateway) using Ethernet CAT cables
with RJ45 plug. (InCoax recommends using CAT5e cable type as a minimum for best performance.) The
firmware of the Modem can be upgraded from the
Controller .
