3com U.S Robotics ISDN TA in Linux

hello all members

I've 3com U.S Robotics ISDN TA & i want it to connect to internet on my Linux box. I use RH 7.3 & 8.0. when i dial through Kppp it connects on 64000 but i've 128K account, but in MS W2K it connect on 128K & runs fine, somebody suggest me to increase speed in KPPP modem speed option but still the same problem.

Re: 3com U.S Robotics ISDN TA in Linux

Ok, I'm re-posting it (seems it posted but it didn't go thru).

When you open and ISDN connection, you open 1 or 2 channels, each of 64 k. Increasing modem speed wont' resolve things, what you have to set up is to use 2 channels instead of one...

User under rh8 hat / system settings /network device control, and add a new interace, which will be your isdn adapter, and chekc to use both B channels.
Here is Red Hat tip on this :
http://www.europe.redhat.com/documentation/rhl8.0/rhl-cg-en-8.0/s1-network-config-isdn.php3

Once you've done it, select this interface in your kppp connection, it should work.

Hi,

In your kppp, what is connection speed ?

Run 'network device configuration' select you isdn device, click 'configure', go to 'advanced' and check that 'Use channel assembler' is selected.

Re: 3com U.S Robotics ISDN TA in Linux

hello

the connection speed is set to 115200 in kppp.

My modem is not appear in ISDN adapter list therefore i add as modem not ISDN in the Network device control option

Re: 3com U.S Robotics ISDN TA in Linux

That's why it doesn't open 2 channels, as modems can open only one.

Try to add values by yourself, selecting another US robotics device, under isdn section, it's quite standard values. But in my RH9 box, us robotics is seen in the list... maybe try to download from us robotics site a driver if you don't succeed.

Re: 3com U.S Robotics ISDN TA in Linux

Hi,

Could you try to set values by yourself ?

Otherwise, go to
http://www.usr-emea.com/loc-index.asp?loc=mest
You'll need your ptoduct serial number, and you should be able to get a driver here.

But I think that default values should do, as a TA is not hard thing...
