Overview:
---------

        This application note facilitates the configuration of Gandalf's LanLine ISDN 
Bridge Products, referred to as "Gandalf Bridge", with Citrix "WinView for Networks".  
Gandalf Bridge products provideremote networking over ISDN lines.  LANLine remote 
access products support both IP and IPX networks, providing a bridge between the "Local"
network and a "Remote client or network".  Remote PC's can connect to "Local" WinView
Application servers using the Citrix Lanlink client software.  In addition, on-Lan PC's on 
the "Local" side can connect to "Remote" WinView Application servers using the Citrix 
Lanlink client software.

Disclaimer:
-----------

        The scenarios described in this document have been tested by Citrix.
Other variations to the scenarios described in this document may work, however
they have not specifically been tested by Citrix.  In order to recreate the
configurations, you should use the specified revision levels of all software
products described in this document and stay within the bounds of the features
and functions described in this document.

        Please note that this application note is a living document and will be
modified as new information and versions of the software described herein
become available.  Make sure you have the latest version of this document
before you begin.  The latest version is always available in the Citrix Forum
on Compuserve.

Requirements:
-------------

	Gandalf "LANLine" Series Intelligent bridge on both the remote and local side.
	
	ISDN lines installed at both the local and remote site

	Citrix "WinView for Networks" Application Server Software - minimum one copy

Setup:
------

        1) It is suggested that you follow the individual steps in the
           Gandalf User's Manual to install the LANLine Series bridges

         2) Install the WinView Application Server software as per the 
	Citrix Installation Guide.

        3) Configure a Citrix LanLink client as per the Citrix Lanlink 
            User's Manual


Operation:
----------

        1) If the Gandalf Bridges are operating and the ISDN lines are active,
	the "remote" network should appear as if it is local.  Depending on 
	Gandalf bridge equipment purchased your bandwidth will be either
	128kbps or 384kbps "uncompressed".  Gandalf's data compression
	combined with the Citrix Lanlink compression provide excellent
	performance for several simultaneous connections over the bridge.

         2) The LANLine bridges can be configured and managed remotely by 
	any SNMP management system.

        3) From a PC Client run the Lanlink program.  From the LanLink main 
	menu, Choose "Connect to AppServer", highlight the desired Appserver
	and press enter. Save the configuration,F4, From the Lanlink Main Menu
	select "Connect to and Appser", highlight the desired selection and press
	enter.  A WinView Login prompt should appear momentarily.


Notes:
------

        The Gandalf LANLine Series Bridge products are an excellent way to access 
        remote LAN's.  Special features on the LANLine series Bridges allow connections 
        to be initiated or dropped, transparently to users, giving the remote office a 
        virtual presence on the central site LAN, while keeping "line charges at a minimum".  
        Combined with data compression rates of up to 8:1, LANLine solutions can make 
        ISDN an affordable alternative.

        In addition, LanLink greatly improves the performance of the ISDN Bridge because the
        execution of the applications is performed on the WinView server
        only requiring screen updates and keystrokes to be sent across the
        bridge.  The majority of the network traffic will be between the WinView
        server and the Netware server which should be on the same local network.


Problems:
---------

        There are no known problems when using Gandalf LANLine Series Bridge Products
         in conjunction  with WinView for Networks Application Server software.
