This document applies to
these PC Cards :
- MC218 (COM One Communication Card, 3 in 1).
- MC220 (COM One Platinium Card, 4 in 1).
- MC222 (COM One Platinium Card, 2 in 1).
- MC223 (COM One Platinium Card, 3 in 1).
OEM note : Most of the
information's of this document are true for our OEM products too.
On the ISDN adapter, what is
the status of the 2 leds after starting the computer ?
- The 2 leds are lighted on O O : there's a hardware
problem.
- The 2 leds never light O O : something is wrong in the installation
(or hardware failure).
When you plug the ISDN adapter to the card under Win 95/98, or when you
start Windows (all versions), the leds will switch on for 2 seconds then switch
off.
This mean the initialization between the PC Card and the adapter is OK
Orange led : mean the ISDN network has assigned you a TEI number (note:
behind some PBX the led is off until you do your first ISDN call, this is normal).
Green led : mean "connected" (remote has answered).
- What is the operating
system used ?
- In the Control panel /
Modems, what do you see ?
(You must see the “COM One Platinium
…” driver, a wrong driver (ie. “Standard PCMCIA driver”) can work for PSTN but
don’t work for ISDN -> you must remove it).
- In Control panel / System /
tab Devices manager, do you see any conflicts or anomalies ?
- Does the firmware version
(display with “at *i”) match with the TECH driver version ? (ie. M11 with
TECH0359. See DRV_MC22x.doc for more details).
- Before to install ISDN, did
the PSTN mode worked ? (if not, we recommend to test PSTN first).
- With drivers up to v1.7 : Icon
SX128 / button Test / call a ISP number (example: +33 (0)8 36 06 13 18).
- With drivers since v1.8 : in the task bar open COM One control panel / line
“Connection test” / call a ISP number.
Note: The most common error
message returned is : "Local configuration not correct", it does not
provide usefull information.
To know it, do you need to
enter a first prefix number before to dial? if yes then you're behind a PBX.
Note for MC220 ISDN : during the boot the 2 leds switch on, and after, the led
"orange" keeps lighted, this may mean you're onto an ISDN PBX.
If you're calling from behind a PBX:
- Usually lines are setup for voice only, is your ISDN line configured
for Data? (to check with the PBX administrator).
- Try to call from a direct ISDN line (direct ISDN switch on the orange led the
first call, then orange led keep switched on, it's normal).
- Some PBX requires the ISDN device to present it's number before to be allowed
an outgoing call (open the SX128 control panel / Tools / Fill the box
"Default calling address" with the ISDN line identifier number / OK /
OK / restart Windows).
If the computer own a internal
modem (i.e. "TOSHIBA Internal V.90 Modem"), we recommend to
disable it (control panel / system / devices manager / modems).
Infrared (IRDA) : you may have to
disable it (Control panel / System / tab Devices manager / Infrared devices /
disable "Infrared communication device").
Before to install ISDN
drivers, PSTN driver must be installed and dialup networking must have been
tested with PSTN (this allow WinNT 4 to manage correctly RAS and network
settings).
Note 1 : When you boot the
computer, the PC Card and the ISDN adapter *must* be plugged.
Note 2 : when you install the PSTN driver
(Control Panel / Modem), Windows must detect the PC Card : you must
NOT select a COM port in the list.
If Windows do not detect the PC Card, this mean something is wrong into Windows
NT 4 or into the BIOS. Windows is not be able to detect any PC Card modem (even
from other brands).
Can you do analog trough ISDN
? :
Run HyperTerminal, select the PC Card driver, type "ati" to check
you're using the analog driver and not "SX128 MODEM" then try to dial
an analog modem:
at s95=44
at dt 0836061318 (call any analog modem number)
If you see the "CONNECT" message, analog
trough ISDN is working. Report this information to the technical support.
If the user own a MC220 LAN
adapter, does it work ?. Report this information to the technical support.
For computer's having a dual
boot (ex: WinNT 4 + Win 95) : Does the ISDN works under the other
OS ?. Report this information
to the technical support.
Card managers examples :
- SystemSoft's Card Wizard.
- Softex's Phoenix Card Executive (mainly installed on Dell Latitude
notebooks).
- Award CardWare.
The MC22x ISDN/LAN and MC22x ISDN functions, can't work under WinNT 4 if some
card managers are installed because MC220 ISDN/LAN technology requires a direct
access to PCMCIA controller.
You must uninstall the
software in order to install and run the ISDN/LAN functions.
Note that most of Dell notebooks
can not support PC Cards without Softex !…
Note: PSTN and GSM modes work without any changes.
DUN stands for Dial Up
Networking (named Remote Access Service under WinNT 4).
Error 630 : The computer is not
receiving a response from the modem.
Check
the modem selected into the DUN is a "SX128 MODEM ..." and not
"COMOne Platinium Card".
Error 678 : The computer you
are dialing is not answering. Try again.
- Check if you are dialing the right number (i.e.: add or remove prefix).
- This error message can appear after an update of ISDN drivers. Go in the
properties of the DUN connection, then reselect the "SX128 MODEM ..."
driver.
Access from : icon SX128 /
Tools / Diagnostic / Diag / Save as, then file opens automatically.
What's the right value of CSC
? (Card Services Connector)
0 = mean driver don't see the PC Card.
1 = mean driver see the PC Card (mean the ISDN interface is plugged to the PC
Card).
IIC (the value is coded in bits)
2047 = mean driver see the PC Card but not the ISDN adapter.
An IRQ is only used when you
open a B channel (Test function doesn't use a B channel but only the D
channel).
From about v1.6, our driver use the same IRQ as the modem COM port. Check if
the BIOS doesn't reserve it, else disable PnP for this IRQ into the BIOS.
- After CAPI installation
(with ISDN driver 2.0), you can see the device into "Control Panel"
/ "Network" / "ACOTEC CAPI20 Protocol v1.1 -> SX128 MAC
Driver for CAPI-Subsystem".
- Applications working with CAPI 1.1 should be able to work with CAPI 2.0 too.
- We have used the following CAPI applications:
T-Online 2.0x - 16 Bit CAPI
ZOC (Terminal Program) - 32 Bit CAPI
cFosWin - 16 Bit CAPI
Symantec PC AnyWhere v8
- The following applications did not work correctly :
WinFax PRO 9.0 (fax via CAPI 2.0)
AVM CapiPort
Q: Why can't I fax via CAPI ?
A: It is not possible faxing using CAPI because it would need a additional
software to create the analog modulation and we don't provide this software.
This should be possible by adding a software as Acotec or RVS Comm, but we've
not tested this solution.
Practically it is not interesting to use CAPI fax software : this kind of
software is big (10 Mb) and slow down the system. The hardware of the MC220
does the same thing !.
Conclusion : To sent faxes, we recommend to use the analog part of the
MC220 (select the analog COM port).
Symantec Winfax Pro 9.0 error message known : "The CAPI installed
on your system does not support the G3 Fax protocol. You will not be able to
fax with this version of CAPI. Contact your ISDN card manufacturer for a CAPI
update with fax support".
Q : My modem don't see the
incoming call (ie. when doing call back).
A : Our ISDN driver (SX128
Control panel) has a default value: the sub address is set to "01".
This permit to avoid the PC Card ISDN get any incoming ISDN call (ex.: ISDN
phone calls).
1) This mean that is you want to receive an ISDN call, others must dial
"your number" + "*01"
Ex: "0556693080*01"
BUT: this service named "local sub address" is not supported by
default by your telecom installation.
2) The second (more simple) solution is to remove the value "01" from
the sub address box, then restart Windows.
Now, the PC Card ISDN will take any incoming ISDN calls !.
Control panel / Services /
Network / Remove Access Service / Configure the communication device (usually
"SX2TAPI (ISDN 1)" ) for "Dial out and Receive calls".
For more information :
For
external ISDN devices: call back with "Dial Out only" works. With
ISDN (internal) TAPI devices : with "Dial Out only" the computer don't
see the call back. You must set "Dial Out and Receive calls".

Changing PC Card IRQ
COM One technical support 21/10/98
1) Get COM port used by the PC Card
-----------------------------------
Control panel / Modems
select the modem line then click "Properties".
Get the COM Port used by your modem (ex: "Port: COM3").
2) Know free IRQ's
------------------
Start / Programs / Administrative Tools (Common) / Windows NT Diagnostics
Tab: Resources
Write down all the values not used between 01 and 15. These are free IRQ's.
3) Know values used by all Serial COM ports
-------------------------------------------
Click the button "Devices", then double click the choice
"Serial".
Now you get a window named "Serial Properties"
containing all the "Interrupt Request" and "Input/Output
Range" for each COM
port.
Note: The PCMCIA COM Port values should be the 2 lines of the bottom of the
list.
4) Changing your modem IRQ
--------------------------
Control Panel / Ports
Click the COM port used by your modem, then "Settings" / button
"Advanced" now
try changing the IRQ to a free value.
You will have to restart Windows NT 4.

MC218 : we recommend
firmwares from xxxxWW.H45 and next.
MC220 : support ISDN from firmwares xxxxWW.L10.
Some patches files are available
for ISDN drivers, these are described into the DRV_MC2xx.DOC document.
MC218 is compatible with ISDN
drivers of MC220 up to version TECH0359 (recommended).
MC218 / MC220 note : with old drivers (from
1997) the ISDN control panel was a white icon “SX128” in the task bar. Since
year 2000, it is replaced by a red and white “COM One” icon.
