1.1. Identiﬁcation

This document describes the capabilities of a Protogate Freeway® which can be used to enhance security.

1.2. System Overview

The Protogate Freeway is a data communication system which connects one or more serial-link channels

(Wide-Area-Network, or WAN channels) of various types to one or more IP (Internet Protocol) networks. The

Freeway acts as a gateway, providing WAN channel access to clients on the IP network.

All Protogate Freeways run custom-built software which is written and provided by Protogate, and which completely

controls the Freeway. The Freeway software is based on a version of the FreeBSD operating system which has been

modiﬁed to control one or more Protogate Intelligent Communications Processor (ICP) boards. ICP boards are

Protogate-manufactured boards which can be installed into a Freeway chassis, plugged into one or more serial-link

channels, and conﬁgured to implement a data communications protocol. Each ICP board installed into a Freeway

provides 2, 4, or 8 WAN ports.
