ISDN modem to wireless router problem

[bavaria34]

The only "fast" speed net access in my area is ISDN.No ADSL and no broadband
The Telco (Telstra Australai) provides a terminal(modem) called an NT1PlusII .
However the data output is via an RS232 plug or USB.
Most routers need ethernet plugs/cables.
It appears that USB to ethernet converters which will convert a USB DSL/Cable modem's USB port to ethernet do not exist. The problem being basically that there is no way to load the necessary drivers onto a DSL/Cable modem to let it know how to talk to the converter.
I'm trying to set up a wireless network in my home/office
My question is..do any ISDN modems have ethernet output..or is there any way to connect a Netgear FM114P wireless router to an ISDN modem that only has the outputs as described(ie USB and RS232 )
Are there any other alternatives?

thanks in advance

Have you asked Telco about it? Pehaps they have a different modem or can recommend one that will work with their system. Actually, I have an SMC 7004BR(?) modem that has a serial interface for a back-up internet connection for sale if you're interested. Then you can plug your wireless into this one. PM me if interested.

thanks Toad
They don't have another modem, and don't offer any other options...they were very pleasant though I must say.
I am going to try the Eicon Diva LAN ISDN and see how that goes.
ISDN Europe/US must be the same everywhere right?(I hope!)
