It is always advisable to install an MRi ISA modem by setting the jumpers to plug n play if you are not sure about the configuration of your hardware. (This dos not apply to users of WINNT4). This way you reduce the risk of com port, I/O and IRQ conflicts.
Windows will automatically detect the modem and install it once the correct drivers are provided. The detection normally occurs just after your Windows logon password, or just before the desktop appears if you do not have the password feature enabled. P n P jumper settings are :- JP4, 5 & 6 = 2 & 3, JP8 ON.
All MRI PCI modems are plug n play only therefore Windows 95/98 must auto detect the card during boot up for the modem to install properly.
If the card is not auto detected, going through the Start - Settings - Control Panel -Modem - Add procedure will be a complete waste of time.
Try powering down the PC, remove the card and re-install on another free PCI slot ( preferably PCI slot 1) and re boot. If the card is still not being detected, make sure that it is not present in Device manager with an exclamation mark by it. If this is the case, remove it from Device manager and re boot the machine.
Mri PCI modems have a setup.exe file written specifically for installation under NT4. The location of the file is usually found on the CD provided under the driver subdirectory. Once the file is executed, the drivers are installed and the 0/S requires rebooting for the modem to be active.
(This rule applies to all except the Motorola chipset modem. The com port must be added first and before restarting, the modem is then added, using the newly created com port.)
Check that you are able to communicate with the com port that the modem is installed on through modem diagnostics. This is done by going to Start - Settings - Control Panel - Modem - Diagnostics - More Info. If the response is either "port already open" or "couldn't open port" then it is possible that another application is using or attempting to use the modem, or the application you might have recently used has locked the com port. Restarting the PC is advised.
If the reply to the diagnostics is "The modem failed to respond", make sure com port, IRQ and I/O settings are correct and not conflicting. If these settings prove to be OK, try replacing the modem.
If you are able to communicate OK, the next check is in dial-up networking properties, to confirm that the Connect Using box is configured to use the correct modem driver.
You must confirm that the installation is correct. External modems support plug n play therefore it is advised to have the modem powered on and connected through the serial port when powering on the PC.
If Windows auto detects the card, provide the driver when requested. There is no need to cancel this operation and manually install it through Control Panel - Modems - Add
If the card is not auto detected, then it is possible that the com port is not enabled in the BIOS. Enable the port and try again.
The drivers for this modem require MMX instructions built into the processor to work. Therefore the minimum requirements are a Pentium 166 MMX and above. Pentium classics and non-MMX Intel or AMD processors are not supported.
This is due to the aquisiton of Smartlink by Conexant and a delay in updating the drivers when Microsoft brought out Service Pack 2. Please download the updated version from our website, which should solve this problem.
Further information can be found here.
Many of the newer Dell PC's have only been built for setup they have created, so there is a lack of power supply from the PCI bus, issuing at 2.2V when the card requires 3V.
Copy the WAN folder for Windows NT to a location on the hard drive. Go into ‘network’ in control panel add an adapter and point to the folder you copied to the hard drive. The correct description should be ‘Conexant PCI ADSL WAN Adapter’. Once this has been added immediately go into ‘Services’ – ‘Remote Access Service’ and add the adapter which should be listed there in the choices. Upon restarting it should be possible to make a connection.
We do not support non -Windows drivers for our ADSL modem range. 3rd party drivers for our PCI cards are available online, but these are not supported by us. In general, we would advise customers who use a non-Windows operating system to purchase a router, as these do not require drivers, only a machine to have a network card and operating system that supports the TCP/IP protocol.
All ISP’s based in the U.K. that use BT phone lines use the same line settings for the router’s purposes. If your telephone service is not provided by BT you should contact your ISP for the required settings. They all require that the following settings be entered in the router configuration. The type of encapsulation should be set to PPoA VC-Mux, the VPI set to 0 and the VCI 38 and that ‘Bridge’ be set to ‘Disabled’
On the ADSL-R/G and the ADSL-R/S/G all of the required settings can be entered in the ‘Quick Configuration’ section. ‘Default Route’ and ‘Enable DNS’ should be set to ‘Enabled’. Once this is done press ‘submit’ and then go to the ‘admin’ section press ‘commit’ to save to firmware.
Every ADSL line has an individual username and password given by the ISP and these should be entered in the router configuration. If your ISP is AOL you will need to contact them for the true username and password as these may differ from that which is required to be entered in the AOL software. If you use BT Broadband and have an ADSL-R/G or ADSL-R/S/G you should enter the password as being the same as that of the username.
Make sure that in your network card properties that you have specified the default gateway and the primary DNS address as being that of the router.
| MRi Code | Model # | IP Address | Subnet Mask |
|---|---|---|---|
| ISDN-R | 192.168.1.1 | 255.255.255.0 | |
| UDSL01 | PT3806 | 10.0.0.2 | 255.0.0.0 |
| ADSL-R | RTA020 | 192.168.1.1 | 255.255.255.0 |
| ADSL-R/G | AR502 | 192.168.1.1 | 255.255.255.0 |

On the ADSL-R/G or ADSL-R/S/G, from the main configuration page go to ‘Services’ then ‘NAT’. In the white box select ‘NAT Rule Entry’ then ‘Add’. For most port forwarding entries you would create an RDR ‘rule flavor’. The local address is the IP address on your network that you want to host the desired service and the global address will be the public IP address assigned by your ISP. If you have an ADSL-R using the Conexant chipset you add the required entries in the Virtual Server section.
It is suggested you read the following article.
None of MRI’s ADSL Routers support Universal Plug and Play by default. You can get most of the functions working through port forwarding, but not video. To do this you will need to disable NAT in the router configuration.
If you disable NAT you can only access the internet by enabling the ‘ZIPB bridging’ function or routing through a block of public IP addresses from your ISP. If you enable ZIPB Bridging this effectively makes the router an Ethernet modem and all of the internet functionality is transferred to a single machine. It is only available on the ADSL-R/G or the ADSL-R/S/G. To do this enable the function in the ‘Bridging’ section of the web configuration and create a DHCP scope in the LAN section with a range of 2. eg 192.168.1.1 to 192.168.1.2 on the default setup.
If you have an ADSL-R (Conexant Chipset) you can go into ‘Miscellaneous Configuration’ and enable ‘PPP Half Bridge’. The other steps are the same as the other routers.
If you have a block of IP public addresses from your ISP with the ADSL-R you set the address specified for the router from the ISP in both the LAN configuration and WAN configuration and disable NAT and DHCP. If you have an ADSL-R/G or ADSL-R/S/G and have a block of public IP addresses you should email technical@mri.co.uk for a solution.
Make sure that any software firewalls are turned off when configuring the router as these interfere with configuration pages.
Firstly make sure you have specified a static local IP address for the PC that is hosting the service. Then specify the default gateway and primary dns server as being the ip address of the router.
On the ADSL-R-G and ADSL-R-S-G go to services, then NAT. Change NAT Global Info to NAT Rule entry. Add a NAT rule. Note the following points:
1. Rule ID should be listed in order of priority after number one, which should be preserved in its default sate.
2. Local address should be the IP address of the machine that is hosting the service.
3. Global addresses should be left as zeros.
4. Port numbers should match those specified in the applications documentation. Local port can either be left as zero or the port number of your choice.

On the ADSL-R-G and ADSL-R-S-G go into IP Filter and set the security level to medium or high. Port stealthing can’t be done on the ADSL-R without additional software or hardware.
Setup for the ADSL - R and ADSL -R-S-G
1. Configure the LAN address and subnet mask of the router to that advised by the ISP.
2. Configure the pc's with the ip address and subnet mask details advised by the ISP.
3. From the command prompt enter telnet then the new ip address of the router. Enter the username and password.
4. Type delete ppp intf ifname ppp-0. Once this is done you should get a message saying 'entry deleted.' Either this or a message saying that no entries exist. If this appears proceed to the next step.
5. Type create ppp intf ifname ppp-0 ppoa lowif aal5-0 numif eth-0 droute true. You should get a message saying 'entry created'
6. Type 'commit' then enter then 'reboot' then enter
7. Go back into the web interface enter the ISP details in the 'quick configuration' section. Check that VPI is '0', VCI '38'
8. Set 'DHCP server' to none and 'NAT' to disable.
9. Commit changes and reboot.
For users of Win95, the MSISDN11.exe accelerator pack must be installed first before placing the card into the PC. This file is included in the CD provided. Power down, place the card into the PC, and power up to continue with the installation.
This card is plug n play only therefore it must be detected by Windows during boot up for the installation to work properly. If the card is not being detected, try another PCI slot (preferably slot 1).
Confirm that the "Connect using" box in dial-up networking properties is configured to
connect using one of the two ISDN line drivers. If it is and you are unable to establish a connection
with your ISP, go to Start - Settings - Control Panel - Modem and select Add. Leave the "Do not
search for a modem" box unchecked and select Next. Windows will communicate and query the two ISDN
com ports and eventually return with a message saying "found Standard modem" on the ISDN port.
You should select "change - have disk" and browse the following path on the driver CD:
x:\card\win9S or x:\card\win98. Click OK and a list of ISDN models will be displayed.
For internet or remote server connection it is advised to use ISDN (Internet PPP 64k) adaptor. Repeat this process for the second ISDN com port.
Now configure the "Connect using" box in Dial-up networking properties to connect using one of the two installed ISDN com ports.
Remove the ISDN card from Network - Adaptors. Enable the RAS service to be running using a Standard modem driver on one of the 2 physical com ports from the NT4 hardware compatibility list. Re boot the PC and go into Control Panel - Network - Add to re-install the ISDN card. Once the card is installed both ISDN ports can be added to RAS. Remove the standard modem driver and re-boot NT.
Go into Dial-up Networking Properties - Multilink, select Use Additional Devices and add the two ISDN lines with the telephone numbers supplied by your ISP. Some ISP's require a second number for 128k connection, otherwise use the same number
In RAS both ports must be configured to dial out. Go into Dial-up Networking - edit Modem & Entry Properties and set "Dial using" to Multiple lines. Select configure and tick both ISDN lines. Configure the telephone numbers to dial
AOL 8 has compatibility issues with the current range of ISDN cards. Please use the reference drivers found at www.billion.com
