OPENCONNECT SOFTWARE PRODUCT SOLUTIONS

OpenConnect/TELNET Client and Server

OpenConnect/TELNET (OC/TELNET) Client and Server software products
feature all the capabilities of the industry standard Client and Server
applications for two-way terminal communications between two separate host
systems.  The Client performs the role of requester of a service, while the
Server acts as a respondent, performing the Client's request.


OpenConnect/TELNET Client

OC/TELNET Client is a software application which resides on an IBM mainframe
or midrange system as a VTAM or APPC application, respectively.  A 3270 or
5250 user on an IBM host can invoke the OC/TELNET Client and provide it with
the name of the destination TCP/IP host.  OC/TELNET Client makes the request
through the OpenConnect Server to the TCP/IP host Telnet Server, and the user
is then logged on in full screen emulation mode as a local ASCII device, such
as a VT100 or VT200 terminal.  A user no longer needs more than one terminal
to access various host systems.  All the functionality of a local user is
offered to all the networked hosts from a single IBM terminal.

Also supported in the OC/TELNET Client for MVS is the TN3270 Client protocol.
This valuable feature proves essential when a TCP/IP network includes several
IBM hosts which need to communicate with each other transparently across the
TCP/IP backbone network.  OC/TELNET is available on IBM MVS, VM, System
36, System 38, and AS/400 operating environments.


OpenConnect/TELNET Server

OC/TELNET Server is an optional software feature available for the OpenConnect
Server providing IBM 3270 and 5250 terminal emulation access for TCP/IP
users into the SNA network.  This application allows TCP/IP hosts supporting
a local Telnet Client to connect to OC/TELNET Server for inbound 3270 and
5250 terminal emulation.  This application also features high-speed graphics
pass-through between IBM mainframes and asynchronous terminals and
workstations for those applications supporting the Tektronix CX graphics
functions.


OpenConnect/FTP

OpenConnect/FTP (File Transfer Protocol) Client and Server (OC/FTP) products
feature all the capabilities of standard FTP Client and Server applications
for TCP/IP.  Residing on an IBM host system, OC/FTP provides transparent
transmission and reception of data and program files between the TCP/IP and
SNA networks.  OC/FTP allows you to interactively move files, remove files,
list directories, rename files, and view file transfer status.

Using the OC/FTP Client application, a user on an IBM host can initiate file
transfers to and from hosts on a TCP/IP LAN, both interactively or in batch
mode.  If a user on a TCP/IP network host requests a file transfer from the
IBM system using a local FTP Client application, the request is serviced by
the OC/FTP Server on the IBM.


OpenConnect/Presentation Services

OpenConnect/Presentation Services (OC/PS) is a software option for the TCP/IP
host offering enhanced terminal emulation into the SNA network.  OC/PS
provides such powerful features as:  3270 Models 2, 3, 4, and 5 emulation,
3287 local printer support, PC File Transfer, color support, 3770 RJE
emulation, International Character Set support, and an Application Program
Interface (API) for programmatic access.  OC/PS, Version 3 introduces TN3270
and TN5250 client support, offering 3270 and 5250 service to IBM hosts with
IBM's TCP/IP via a number of TCP/IP attachment devices.  These devices
include attachment to Ethernet, Token Ring and X.25.  Also available from the
OC/PS, Version 3 family is TN3179G, which enables users on a TCP/IP network
to emulate a 3179G All Points Addressable (APA) device to gain access to
graphics applications on IBM mainframes.  TCP/IP users can have just one
terminal emulation program that meets all of their emulation requirements.


OpenConnect/APPC

OpenConnect/APPC (Advanced Program-to-Program Communication) provides
a powerful, direct method of communicating program-to- program between
hosts on an IBM SNA network and those in a TCP/IP environment.
OpenConnect/APPC (OC/APPC) is a software package residing on the TCP/IP
host providing SNA Logical Unit 6.2 (LU6.2) library support, implemented as
a set of C language procedure calls.  The LU6.2 protocol provides a
generalized facility for application-to-application communications using
standard IBM bi-directional, half-duplex data streams between communicating
transaction programs on IBM and TCP/IP hosts.

OC/APPC also provides the lower layers of SNA required for the actual
transmission of data through either a host-controlled (PU2.0) or a
peer-connected (PU2.1) SNA network.


OpenConnect/IP Router

OpenConnect/IP Router allows you to route and transfer data packets from one
TCP/IP network, over your SNA backbone, to another TCP/IP environment.
Data packets are enveloped and transferred with no effect on the data as it
passes through the SNA environment.  A system half the world away appears
to be next door.  The OpenConnect/IP Router saves the cost of setting up a
totally separate network, plus provides network management capabilities
through NetView.


OpenConnect/Control Program

When routing LAN-to-LAN traffic over an SNA network, routing tables are
maintained from a central location on an IBM system using the
OpenConnect/Control Program (OC/CP).  Depending on your system
configuration, one copy of OC/CP may be all that is needed for routing
management of an entire worldwide network.  OC/CP is provided for both IBM
mainframe and midrange systems.


OpenConnect/SNALink

OpenConnect/SNALink is a co-existence feature that provides connectivity to
IBM's provided TCP/IP protocol software creating routing sessions to and
from IBM's SNALink (IBM's TCP/IP interface).  This feature provides TCP/IP
LAN users access to IBM TCP/IP applications, such as NFS, through the
OpenConnect Server.


OpenConnect/Mail Bridge

OpenConnect/Mail Bridge converts Simple Mail Transfer Protocol (SMTP) based mail
 documents from a TCP/IP

network to Systems Network Architecture Distribution System (SNADS) documents
 providing a user-transparent
interface between these two commonly used electronic mail systems.  Your users
 continue using their existing,
familiar E-Mail system which now spans beyond their local network, exchanging
 mail messages with users on a
totally
different network.


SAMPLE BUSINESS APPLICATION PROBLEMS OPENCONNECT SYSTEMS CAN
SOLVE

Terminal Emulation - IBM and Non-IBM

Do your users require multiple terminals at their desks to access different
hosts?  Would you like to give your users access to applications on systems
other than their local host?  Multiple terminal emulation capability from a
user's device is a common requirement.  OpenConnect products offer you a
wide variety of emulation features for communication between IBM SNA hosts
and systems on a TCP/IP LAN, such as UNIX, VAX and DOS environments.
OpenConnect/TELNET and OpenConnect/Presentation Services products give
your users bi-directional terminal emulation flexibility.  Now your IBM
3270 and 5250 users can be full screen users on your non-IBM hosts, and
your Async users can be full screen IBM 3270 and 5250 users of applications
on your IBM mainframe and midrange systems.  OpenConnect/TELNET Server
resides on the OpenConnect Server and is invoked by a user's local Telnet
Client application.  OC/TELNET Server offers 3278 Model 2 and 5250 emulation
and a special graphics pass-through feature for those devices that support
Tektronix CX Graphics data streams.

OpenConnect/Presentation Services offers you a more complete set of emulation
capabilities for inbound terminals to an IBM host.  Included are features such
as Models 2, 3, 4, and 5 emulation, local 3287 printer support at your TCP/IP
host, full color emulation, International Character Set support, and an
Application Program Interface (API).  Now your TCP/IP users have all the
functionality of a local 3270 device, and more!  OC/PS, Version 3 with
TN3179G emulation extends the functionality even further to include IBM 3179G
All Points Addressable graphics emulation.  Now your TCP/IP LAN users can act
as a 3179G device to access the powerful graphics applications resident on the
IBM mainframe, such as GDDM applications, Interactive Chart Utility, and
others.  OC/PS, Version 3 introduces the common TN protocol for the 3270,
5250 and 3179G emulation.  This opens up your usage of Ethernet attachment
devices to include not only the OpenConnect Server, but also the IBM 8232,
3172, and other configurations that support the TN Server protocol.

All the OpenConnect/TELNET and OpenConnect/Presentation Services products
include full keyboard mapping and interactive HELP screens to assist your
users as they become familiar with their new capabilities.


File Transfer - Sharing Data Between Dissimilar Hosts

Moving data between IBM SNA hosts and TCP/IP-based hosts, such as UNIX,
VMS, DOS and others, is a common requirement.  How to move data efficiently
across dissimilar hosts not only to process the data, but also to submit
jobs for print, calculation, analysis and database updates is a common
problem.  OpenConnect/FTP Client and Server products offer the ability to
request and service data requests across the SNA and TCP/IP networks.  An
IBM user or application can issue a request for file transfer using a local
OC/FTP Client.  This can be done both interactively and in batch mode.  The
OC/FTP Client connects to the destination TCP/IP host's local FTP Server to
 fulfill the requested service.  OC/FTP

Server on the IBM host responds to
and services requests from FTP Clients on the networked TCP/IP hosts.
Using the OC/FTP Server, jobs can be submitted directly into printer and
reader queues to maximize the use of printer and computer resources.  Data
can be moved between the networks in two other ways with either
OpenConnect/Presentation Services 3770 or PC File Transfer (IND$FILE).
OC/PS 3770 allows your TCP/IP users 3770 RJE emulation into the SNA
network.  An Application Program Interface (API) is also available for
these products to automate repetitive functions performed by users.


LAN-to-LAN Communications Over Your SNA Network

How do you bring geographically dispersed networks, SNA and TCP/IP LANs
under one virtual network, and manage it?  That question plagues many
companies.  Using the OpenConnect products and the OpenConnect/IP Router,
your remote networks can be brought together using the resources available
in your SNA network.  With the IP Router, you eliminate extra lines, modems,
equipment, and network management nightmares.  The OpenConnect/Control
Program provides you with a central management facility to manage the
routing paths for TCP/IP LAN-to-LAN communications using the SNA network
as a transport.  Users on one TCP/IP LAN can access another TCP/IP host on
a separate LAN using the SNA network as the carrier.  Plus, you get the
benefits of SNA and TCP/IP internetwork communications for terminal
emulation, file transfer, and all the other exciting features of the total
OpenConnect product family.


IBM AS/400 and System 3X Interoperability with TCP/IP Host

Another requirement you may be facing is how to provide communications
between applications and users on IBM midrange systems and TCP/IP hosts
running such operating systems as UNIX, AIX, DOS, VMS, and others.  The
rich feature set of the OpenConnect Server and software products brings
all these systems together for enterprise networking.  The OpenConnect
Server, both the SDLC and Token Ring models, provides the gateway function
between your AS/400 and/or System 3X systems and your TCP/IP LAN-based
hosts.  Now Async users on the TCP/IP hosts can be full screen IBM 5250
users on the IBM host, and 5250 users can be full screen Async users on
a TCP/IP host using the OpenConnect/TELNET.

File transfer requirements are met with the OpenConnect/FTP Client and
Server.  E-Mail exchange needs can be met with the OpenConnect/Mail Bridge.
Your AS/400 users with SNADS-based E-Mail, such as AS/400 Office, can send
and receive mail with users on the TCP/IP network using SMTP-based mail
products, all with the OC/Mail Bridge.  Users can continue to use their
familiar E-Mail package to interchange mail with users on totally separate
networks.  Distributed application requirements are also met with
OpenConnect/APPC.  Applications on your IBM and TCP/IP hosts are brought
together using the Logical Unit 6.2 program for peer-to-peer communications;
all using one common programming interface.

These are just a few of the business problem scenarios that you may be
facing for internetwork and interhost connectivity.  OpenConnect provides
you with a common bond between your various vendor host systems, for both
application and user communication requirements.  OpenConnect networking
is networking from the user's perspective.
