Dial-up from MT router?

Not being an expert can I check that I understand this?

We’ve a MT Router connected to an ADSL modem as our Internet gateway. The telephone line we’re using has of course the capacity to carry simultaneous voice calls and, I’m guessing, standard 56k dial-up modem traffic.

If we connected the serial port on the router to the serial port of an external 56k dial-up modem and set-up a PPP client on the Router to ‘dial-up’ the ISP’s dial-up number and our account name and password (for dial-up) could we have a failover back-up connection if the DSL line fell-over - or even a maintain a permanent parallel dial-up connection for ie mail traffic?

For this would you use the serial cable that came with the external modem for connection to a PC’s COM port or is a null-modem cable required? What should the Router’s serial-port baud rate be set to?

Anyone?

I’ve a vague idea that it is possible via ISDN provided, a) that I can find an ISDN modem for which RouterOS has the driver and b) my local exchange is ISDN capable. I’ll check on the second and come back if there’s any point pursuing the first.

You can use dial-up from a Mikrotik router, for configuration check this post on the wiki. http://wiki.mikrotik.com/wiki/How_to_connect_your_office_network_with_Dial-up_Modem/Connectivity

You could adapt that with a netwatch script to enable the ppp connection if your gateway/internet connection goes down on your dsl.
