[nsp] IPSec with 2600

[Wired world]

 Hello All,
       
            I am want to establish IPsec between 2
place with 2600 at one end and 3600 at other end. Does
this router support IP sec or we need to change the
IOS on both of router ?

             And does 2600/3600 series support G.703
interface ?


  with regards
