OSI-WAN
The OSI-WAN product is a modular implementation of the four Lower
Layers of the OSI Reference Model and conforms to the following ISO
Standards. The Software was implemented as a Windows NT Kernel Driver
and works with the Digiboard Sync/570i adapter.
The product is
well integrated into the Windows NT networking interfaces and provides
the standard Winsock interface to Applications. The product
also allows direct access to the X.25 Packet Layer protocol to enable
applications to run directly on top of X.25 Packet Switching
Interface. The product is highly configurable and can be customized to
meet the requirements of various industry standard profiles through
editing the configuration parameters in the Windows NT Registry.
Conformance
All mandatory functions for US GOSIP
Version 2.0 are supported.
All mandatory functions for UK-GOSIP (Government OSI Profile)
V3.1/V4.0 are supported.
Interoperability
Interoperability tests are performed
with a variety of vendors' protocol stacks on various platforms as
part of Quality Assurance process.
Features
-
User Friendly
A GUI application for configuration
and administration. Installation and Control are through the Control
Panel-Networks applet of Windows NT.
-
Open, Standard interface
There is a Winsock interface
for OSI application developers. The product offers the standard Winsock
interface on top of the TP02/X25 protocol stack. The product can be
integrated with other complementary products such as OSI Upper
Layers and FTAM through the Winsock interface.
-
Direct X.25 Access
The product also allows applications
to run directly on top of the X.25 Packet Layer through the STREAMS
Message based X.25 Packet Layer interface. This mode of operation
enables communication with other applications running directly on
top of the X.25 Packet Layer. The X.25 applications can setup
incoming call listeners to the Packet Layer either through
sub-addresses or through unique identifiers in the Call User Data
field.
-
Transport Layer
(TP0,2)
Provides End to End Reliable Data
Transfer.
Provides easy to use configuration
parameters in the Windows NT Registry.
Provides USL STREAMS based TPI interface
and Winsock 1.1 interface to applications.
Samples of Winsock application
source code and binaries are included in the deliverables.
Supports T-Selector lengths of up to 32
octets as per the NIST agreements.
-
X.25 Packet Switching
Interface
Provides easy to use configuration
parameters in the Windows NT Registry.
Provides applications direct access to
the X.25 Packet Layer.
Supports simultaneous operation of the
Transport Layer and User Applications on top of X.25 Packet Layer
protocol.
-
Physical Layer
The Digiboard Sync/570i adapter
supports EIA-232D and V.35 physical interfaces. The V.35 interface
is recommended for line speeds higher than 64Kbps.
Diagnostic
Aid
Samples of application source code and
binaries are included as part of the standard delivery and can be
executed as per the Users Guide to insure that the stack is
operational.
A separate chapter is included in Users Guide for administration and
configuration of the product.
Packaging
The product consists of a Digiboard
Sync/570i series ISA or PCI bus adapter, software and two distinct
software items:
-
