The difference is that modular access routers give you more flexibility to expand your router in various ways to suit your network needs by way of having a different and wide variety of modules. Integrated service routers or ISRs do the same thing by optimizing themselves for secure and concurrent transfer of data, voice and images at wire-speed. They provide flexibility on service (security, unified communications, data, wireless, etc.) that you can offer to your users.
