ISDN Interface to SERIAL Interface conversion.

I have a Cisco 1760router. And it only has 1 ethernet, 1 isdn wan interface. Does anyone know any convertor or anything that I could convert the isdn interface to a serial interface. Or any way that I can connect a modem into the Isdn interface to dial out.

Re: ISDN Interface to SERIAL Interface conversion.

You should be able to sell your 1760 or maybe your distributor will allow a trade-in towards another model. There are no adapters available that I’m aware of. You might consider a modular router (i.e. 2600 series) next time so you can just swap out interface cards as your needs change.

Re: ISDN Interface to SERIAL Interface conversion.

According to the Datasheet from Cisco you can add 1 more WAN Interface card into the empty WIC slot available. I would suggest getting an additional serial WAN interface card. There are 2 to choose from. THe WIC-1T and WIC-2T. One with 1 serial port, the other with 2 serial ports.

So far I don't think there are converters available to convert from ISDN to serial. The technology does not allow it.

Hope this helps.

Regards,

Ron
