Cisco 2811 PVDM 32

Answered Question
May 11th, 2009

Hi guys

I am currently trying to configure a 2811 with a PVDM2-36DM and a HWIC-1CE1T1-PRI to allow remote users to dial in using both ISDN and pstn modem access. Is this possible using this combination of WICS?

I have this problem too.

You do not have "ppp authentication eap" in dialer like you do in group-async.

It's called configuration blindness, and it's very common among engineers.

Thanks for the nice rating, and good luck!
