The Cisco SPA508G uses standard encryption protocols to perform
highly secure remote provisioning and unobtrusive in-service software
upgrades. Remote provisioning tools include detailed performance
measurement and troubleshooting features, enabling network providers to
deliver high-quality support to their subscribers. Remote provisioning
also saves service providers the time and expense of managing,
preloading, and reconfiguring customer premises equipment.
