NETWORLD '92 BOSTON, Feb. 10, 1992 -- Newport Systems Solutions, Inc., a
leading supplier of local and wide area networking connectivity products,
today announced the PC2LAN/X.25 remote shell that provides PCs with
cost-effective, asynchronous access to LANs by means of an X.25 network.

A software-only remote shell, the PC2LAN/X.25 is targeted at remote PC
users and traveling professionals. Through the asynchronous communications
(COM) port of their PCs and a modem, the remote shell allows PC users to
gain LAN access via an X.25 network. No additional hardware is needed, and
the software remote shell requires just 8 Kbytes.

"Recognizing the need for connectivity between a large number of remote
asynchronous PCs and a central site LAN, we developed the PC2LAN/X.25
remote shell and modified our LAN2LAN router to meet the need," said Larry
Stephenson, president of Newport Systems Solutions. "Now up to 64 remote
PCs running PC2LAN/X.25 can access the central site and all of its
resources via a single LAN2LAN router. Additional routers may be used if
the connectivity requirement is larger."

Features and Requirements

The PC2LAN/X.25 requires Newport Systems' LAN2LAN router with X.25 Access
to be present at the central site. Using an efficient "packet interface,"
the LAN2LAN router connects LANs together at speeds from 9.6 Kbps to 384
Kbps. Each LAN2LAN router with X.25 Access accommodates a total of 64
remote PCs or LANs.

The LAN2LAN router with X.25 Access and the PC2LAN/X.25 work together to
maximize and preserve the X.25 bandwidth. NetWare broadcast suppression
and IPX overhead compression are two key features included for optimum use
of available bandwidth.

The PC2LAN/X.25 also includes an asynchronous X.25 calling utility with a
script language for automatic call generation. The remote shell
automatically connects the remote PC to an X.25 network PAD (Packet
Assembler/Disassembler). Standard scripts (CompuServe and BT Tymnet) are
included for first time users.

Line speeds up to 38.4 Kbps are supported to allow use of V42bis or MNP7
asynchronous data compression modems.

To enhance performance of applications requiring both file access and
remote execution, remote users may also employ a product that enslaves a
local computer while remotely providing keyboard inputs and screen
updates. Several products, such as Novell's NetWare Access Server v1.2,
can greatly improve remote performance because file access is accomplished
at LAN speeds.

Benefits of X.25 Networks

The major benefit of X.25 networks is that they connect multiple remote
locations through one physical port. With numerous remote PC users, an
X.25 network saves communications costs by eliminating the need for a
separate communications line and for supporting host hardware for each
connecting PC.

Another important benefit of X.25 networks is the nondistance sensitive
method of charging. Remote PC users make local calls to the X.25 network
instead of long distance calls to the central site. Additional charges are
usually based on packets or characters transmitted and the call's
duration, but not on the distance between parties.

"With remote computing becoming a larger and continually growing segment of
the market, the PC2LAN/X.25 can reduce the cost for both central site
managers and remote users by allowing them to use X.25 networks," added
Stephenson. "This software remote shell will help expand the use of remote
computing on NetWare LANs at a very low cost."

The single user price for the PC2LAN/X.25 is $149, and the product is
available now through Newport Systems' resellers and distributors.
Multiple user licenses are available. Prices for the LAN2LAN router with
X.25 Access begin at $2,695.

Newport Systems Solutions, a privately-held corporation headquartered in
Newport Beach, California, designs, manufactures and markets advanced
communications products that offer high speeds and multi-port operation
for increased performance and configuration flexibility in the
fast-growing market for WAN and LAN internetworking solutions. The company
introduced the industry's first data compression router, and recently
added multi-protocol routing to its LAN2LAN family capabilities.
