my environment has the intention to replace the EOL AS5300 gateway. As the number of users are very small, i'm looking @ using 2811 router instead of AS5335 or AS5400 gateway.
Existing users are dial into my AS5300 to get an IP address to access into LAN for email checking, authentication is done through radius (chap).
Some advise needed on what are the required modules to purchase for 2811 in order to support this similar function. Currently, i have 2 x ISDN30 (E1) lines connected to the AS5300 for this function.
For 2811, i have heard variations on modules to be purchase. They are:
1) PVDM2-36DM and HWIC-1CE1T1-PRI
so which 1 should i purchase
