4 Introduction

This document describes some features for a Controller of the model “in:xtnd™ | Control | MA2.5 | 4”. It also

has a the technical specification, as well as information about the regulatory statements and the proper

disposal of the equipment.

This model of the Controller provides a throughput of 2.5 Gbps for the available single coax port.

4.1 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 which manages the Controllers installed in, or near,

buildings and Modems installed in the 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. 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.

4.2 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.

4.3 The in:xtnd™ Control C254

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.
