Product Overview 7
Introduction
Product Overview
The Comtrol™ InterChangeVS™ 3000 virtual remote access server is a
rack-mountable or stackable “network appliance” that connects via
Ethernet to a host Windows NT®or Novell®NetWare®server and
terminates four Basic Rate Interface (BRI) ISDN lines. Each ISDN
line (“port”) consists of two 64 Kbps B channels and one 16 Kbps D
channel: each B channel can be used independently, for up to eight
simultaneous 64 Kbps connections, or the B channels can be bonded,
for connections of up to 512 Kbps. This bandwidth, along with the
flexible data compression schemes that are supported, makes the
VS3000 ideal for site-to-site file transfers and graphics-intensive
Internet/intranet applications.
Features
• Supports both ISDN Datalink Layer ITU-T Q.921 and ITU-T Q.931 D-
channel signaling.
• Supports both North American (VS3000U) and international
(VS3000S) users with the same product family and software.
• Provides the performance and features of a standalone remote access
server with reduced implementation and operating costs.
•Automatic backup server switching ensures that ISDN services stay
available even if the primary server goes down.
•“Hot-swapping” lets you take VS3000 units in or out of service
without downing the server or interrupting other network services.
•VS-Link software gives you direct and immediate control of the
VS3000, including monitoring and diagnostic functions.
•Full support for Windows NT RAS, Novell NetWare MultiProtocol
Router™, and Novell NetWare Connect™ functionality.

8 Product Overview
Introduction
ISDN Service Standards Supported
The VS3000U is designed for North American use and is compatible
with most ISDN service standards, including:
• AT&T, National ISDN-1 (NI-1), 5ESS Custom, and EuroISDN
• Nortel, NI-1, DMS-100 Proprietary (NTI), and EuroISDN
• Siemens, NI-1, and EuroISDN
The VS3000S is designed for international use, or North American use
when connected to an NT1 terminating unit, and is compatible with
most international ISDN service standards, including:
• European EuroISDN (ETSI NET-3)
• AT&T, National ISDN-1 (NI-1), 5ESS Custom, and EuroISDN
• Nortel, NI-1, DMS-100 Proprietary (NTI), and EuroISDN
• Siemens, NI-1, and EuroISDN
Operating System Requirements
The InterChangeVS 3000 requires at least one network server*
running one of the following operating systems:
• Windows NT (3.51 or 4.0) with Remote Access Service (RAS or
RRAS).
Note: The Windows NT 4.0 operating system is required to
support Multilink PPP.
•Citrix
®WinFrame®(1.7 or later)
• Novell NetWare (3.12, 4.11, or IntranetWare™)
Note: Contact Novell Inc. for information regarding Multilink
PPP support for NetWare.
* Two or more network servers are required in order to use the
automatic backup server feature.
Connectivity Requirements
• One to four ISDN BRI telephone lines. (See Working With The
Phone Company, elsewhere in this guide.)
• An Ethernet connection, either directly to a NIC card in the host
server or to an Ethernet hub. (See Installing the Hardware,
elsewhere in this guide.)

10 Backup Server Overview
Introduction
Backup Server Overview
Both the Windows NT and Novell versions of VS-Link support
automatic backup server switching. If you have more than one NT or
Novell server on a network, you can configure one server as the
primary server for the VS3000, and one or more other servers as
backup servers for the same VS3000.
Once configured, primary-to-backup server switching is automatic. In
the event that the primary server goes offline, the backup server waits
the amount of time you specified during setup. If the primary server
does not come back online in that time, the backup server
automatically resets the VS3000 (in the process terminating any calls
in progress), then reloads the VS3000 using the configuration
information stored on the backup server and restores ISDN service.
Backup Server Configuration and Hierarchy
To configure backup server operation, you must install the VS-Link
software on the primary server and on every server that may be used
as a backup server. Then, when you configure the software on a given
server, you follow these steps:
1. Select the specific VS3000 to be controlled by this server.
2. Select whether this server is the primary or backup server for the
selected VS3000.
3. If a backup server, select the amount of time the server waits
(Recover Time in Windows NT, Polling Time in Novell) before
taking over from the primary server.
Each VS3000 must have one and only one primary server, but it can
multiple backup servers. Thus, by configuring each potential backup
server with a different recover time, you can establish a hierarchy that
determines which backup server to go to, and when.
Distributing the Workload
Note that primary/backup server configuration is set for each VS3000
on the network individually. This means that a given server can be the
primary server for some of the VS3000 units on the network, and the
backup server for others.
For example, in the following illustration, server “A” is the primary
server for VS3000-1 and the backup server for VS3000-2, while server
“B” is the primary server for VS3000-2 and the backup server for
VS3000-1. Thus, the normal workload is distributed between the two
servers, but if one of them goes down, the other takes over support of
both VS3000 units.

Backup Server Overview 11
Introduction
Note: VS-Link for Novell can support four VS3000 units (either
primary, backup, or mixed) per Novell server. VS-Link for
Windows NT can support thirty-two VS3000 units per NT
server.
Returning Control to the Primary Server
When the primary server comes back online after a service outage,
backup-to-primary switching is not automatic. Instead, you must go to
the primary server and perform a manual procedure to reassert
control over the VS3000.
On Windows NT networks, access the ISDN Monitor program and use
the Reset option.
On Novell networks, load the vs3kcfg.nlm utility and use the Primary,
Force Load option.

Introduction
Software or Document Updates
For information that is not in this Guide, see README and/or Help
files on the installation media. In particular, the Windows NT version
of VS-Link and the Windows NT ISDN Monitor program include
significant online help.
Comtrol manuals and other documents are available in electronic form
on the Comtrol web site. Driver software updates can be downloaded at
no charge from the Comtrol ftp site. Always check the web and ftp sites
to make sure that you have the current driver and documentation.
The current released version of the software is stored in the VS3000
directory. If a newer version has reached the beta testing stage, it can
be found in the BETA directory. Beta software is made available on an
“as-is” basis and users of beta software assume all risks and liabilities
relating thereto.
Note: Downloadable driver software files are stored in either zipped
(filename.zip) or self-extracting zip (filename.exe) format. You
must extract the zipped files before installing a downloaded file.
For more information, see the appropriate section for your
network operating system.

Overview 13
Installing VS-Link (Novell)
Overview
VS-Link for Novell is a NetWare Loadable Module (NLM) that
supports the InterChangeVS 3000 virtual server. The VS-Link
software works with the following operating system releases:
The VS-Link software supports up to four InterChangeVS 3000 virtual
servers under the control of a single Novell server. VS-Link also
provides for “hot swapping” VS3000 units, in the event that a VS3000
mustbe replacedwithanidenticalunit whilein service,anditsupports
automatic switching between primary and backup Novell servers, in
the event that a host Novell server fails.
The following sections discuss:
• Removing the VS-Link software.
• Installing the VS-Link software.
• Configuring VS-Link for use in a Novell MultiProtocol Router
(MPR) environment.*
• Configuring VS-Link for use in a Novell NetWare Connect (NWC)
environment.*
• Troubleshooting communications with external devices.
• Replacing units in service (“Hot Swapping”)
* This includes configuring for primary and backup server operation
in a multiple-server environment.
