I got a question concerning the IOS installed on my Cisco 876W.
I got a Cisco 876W with ADSL, WLAN and ISDN S/T Inteface and a LAN 4 Port Switch.
I want to use the ISDN as a Backup connection if the ADSL fails.
I?ve read the config guide and there is written that the router uses the isdn normally for remote administration and not as a backup device.
So my question is: Is the IOS image file with advanced security able to use the ISDN as a Backup device or need I the enterprise version of the IOS ?
And has the enterprise version also the ability to build vpns over ADSL and ISDN ?
Thanks for your hel
