Dear TELES Customer,

This file contains last-minute information and troubleshooting tips for the CD
with the TELES ISDN CAPI Version 3.30 and RVS-COM Lite.

CD Installation

Windows NT 4.0

Begin driver installation from CD. During the Remote Access Services
installation, you may be asked to insert your Windows NT CD. When RAS
installation is complete, a system dialog containing "Disk #1G:" may appear.
(G: is intended to refer to the CD-ROM drive). Insert your driver CD and
confirm with OK to continue installation.


TELES.CAPI 3.30


General Information

If your computer has switched to Standby mode (powered down), ISDN applications
may not be able to answer incoming calls reliably, depending on how long your
computer takes to "wake up" from standby. If your computer is not quick enough,
such calls may be lost. This behavior depends on standby settings and overall
system speed. To avoid such problems, adjust your computer's standby settings
or deactivate standby mode.

If you encounter problems when using TELES.BRI Boxes or TELES.BRI/2TR Boxes,
verify that the On-Board Parallel Interface is set to compatible (ECP) in the
BIOS.


CAPI for Windows 95
-------------------

The Miniport driver can only accept incoming calls on a single MSN. If several
MSNs are configured and separated with commas, calls are only accepted on the
last.
If Dial-Up Networking is used, we recommend the installation of Dial-Up
Networking Update 1.2 (included on CD as MSDUN12.exe ).

USB/BRI Box drivers can not yet be removed or deactivated using the Windows
Device Manager. Both actions currently lead to system crashes. (This limitation
does not apply under Windows 98.)

USB/BRI Box drivers can only be removed via the Windows Device Manager if the
system is restarted in "safe mode " Reboot in safe mode by pressing F8 during
the startup procedure before Windows 95 starts. The "Windows 95 Startup Menu"
appears, from which you must select the third option ("safe mode"). Driver
removal can then be carried out in the usual fashion: 1. Open the System
control panel and click the Device Manager tab. 2. Select "TELES.S0/USB-Box"
under "TELES ISDN adapter " and click "Remove".


CAPI for Windows 98
-------------------
The Miniport driver can only accept incoming calls on a single MSN. If several
MSNs are configured and separated with commas, calls are only accepted on the
last.

If your TELES.BRI/PCMCIA II 2.0 returns the ”IRQ or Hardware conflict ” ISDN
Monitor message upon Windows 98 startup, pull the card out and reinsert it.
Drivers will now be properly loaded. You can avoid this error message by
inserting the card after Windows 98 has started.

Die BRI/2TR Box prevents the computer from switching to standby mode.

PCMCIA and PCI cards cannot accept calls in standby mode

If the property sheets for the TELES Miniport lines do not appear in the
Dial-Up Server dialog, make a new connection and they will appear.


CAPI for Windows NT 4.0
-----------------------

Windows NT does not support the ”hot plug” feature for PCMCIA cards. Be sure to
insert your TELES.BRI/PCMCIA into the slot before starting up. Do not remove the
card from the slot while the system is running.

The Miniport driver can only accept incoming calls on a single MSN. If several
MSNs are configured and separated with commas, calls are only accepted on the
last.

If a TELES.VCOMM Modem is used as a RAS Device, the COM port it uses is not
available for other applications and messages such as ”COM3 unavailable or
already in use” may appear

After CAPI removal, the TELES ISDN control panel remains visible until after
restart.

Remote Access Services are only removed during CAPI removal if all additional
RAS devices are removed as well.

Running more than one instance of the ISDN Monitor Statistics program
(Perform.exe) may cause the program to crash.

If the MS Personal FAX Installation cannot find the TELES.Faxmodem, quit
installation, setup a standard modem and restart the MS Personal FAX
Installation.

Under Delrina FAX 8.0, select the TAPI interface for TELES.Faxmodem.
Otherwise, faxes may not be properly received.

Problems may occur after AOL connections via the TELES-VCOMM Modems (COM ports
may appear busy, outgoing calls unsuccessful, incoming calls not accepted,
etc.) if the TELES-VCOMM Modems are later used with other applications. This is
caused by the 16bit version of the AOL software. AOL does not currently offer
a Windows NT version.

AOL dial-in access via the TELES.X75 Modem may often terminate unexpectedly.
This happens when all AOL X.75 lines are busy, as many AOL users dial in using
X.75 modems. Try using the TELES.V120 Modem instead, as the AOL V120 lines are
seldom used.

We hope you'll enjoy your new software.
