The Cisco ISR and ASR have additional slots that support add-on modules such as wireless controllers and VMware ESXi
servers. Deployments can use various Cisco ISR and ASR models to support different features, to scale, and to
accommodate additional services. The modular design enables the Cisco ISR and ASR to be deployed at headquarters,
remote locations, or branch locations. For more information about the various Cisco ISR and ASR models, see the
