Joining Different Neighborhoods

Overview

Two different neighborhoods are joined today through the ComGate^®, a key part of AFTN/AMHS network hosting, developed by Radiocom Inc.

ComGate^® integrates AFTN and ATN networks in ground-to-ground communications environment.

Its capabilities allow full integration with other network hosts and interconnection of different electronic messaging systems.

ComGate^® works with a wide variety of message formats and standards such as X.400/X.500, IA-5, ITA-2, Baudot, SMTP and others.

ComGate^® analyzes incoming and outgoing information, interacting with MTA (Message Transport Agent) and exchanges information with several messaging systems.

ComGate^® opens the door to other AFTN/AMHS networks and sub networks head ends, and due to its connectivity capabilities, reaches the whole Worldwide Web through Internet servers.

The gateway works independently of servers, providing full connectivity to exchange messages with other communication systems, wired or wireless.

ComGate^® allows point to point, or point to multipoint communications and also the connection with secondary networks.

The versatility of this gateway enables the connection to LAN/WAN Ethernet networks, allowing the dialogue between different interfaces using different libraries (API) from the manufacturers of each equipment part of the gateway.

Easy to use

A few screens are necessary to operate the ComGate^® application software.

The following picture shows ComGate's mask:

This simple screen has all the controls needed to operate ComGate^®.
The link properties can be set up in one step, adding the proper parameters.

The user can see all the necessary indications about the connection status through the status bar.
The network administrator can see all message traffic through the gateway.

When a message arrives from the AFTN/AMHS network, this tool shows simple data related to this event while ComGate^® converts the data.

When it delivers a message, headers can be seen in this window.

“Simple tools to facilitate useful control tasks”, is Radiocom Inc. development team’s premise to make the ComGate^®, the versatile and powerful link between AFTN and AMHS.

Connectivity

This system is based on MOTIS (Message Oriented Text Interchange Standard) as defined by ISO inside TCP/IP (Transmission Control Protocol / Internet Protocol). Practically, MOTIS is a complete system to transfer mail messages and not a single protocol, and it is known as MHS (Message Handling
System).
ComGate^® communicates with the MTA (Message Transport Agent) server and MS (Message Store) which operates as post office administered by COTS Server and performs internal message distribution and storage between mailboxes, users administration and system databases.
The following diagram represents a wide variety of systems that could be used to exchange data through ComGate^®.
All kinds of links and interfaces are included in the linking capabilities of ComGate^®, which adapts the data format between AFTN/AMHS networks and manages high traffic density.
It is also used to connect legacy AFTN ATS systems to the new AMHS environment.
