jmarcwsp1,
Yes, You will need a T-1/E-1 Card for each site, most likely a dual at the site with version 6.0. As for licensing you will not need any extra at the version 6.0 site, but you may need it at the 3.2 site as I am not sure if they had the free T-1 licensing back then.
If it is a dry line point-to-point then it would be best to make both sides an E-1 since it would provide more channels for communication; just a suggestion.
Thanks,
TE
