I have recnetly purchased a 2811 router and my ISP is providng me with an ISDN Lan connection with 64 kbps speed. Modem type is Intracom MModel(Netmod) which has a serial interface(RS232 type) with static public ip adrresses. Which is best way to use this link with the router? Does 2811 comes with a serial interface card for this modem or do i need to get an ISDN interface card which will take an RJ11 ?
I have this problem too.
