Keep Cisco 840 phone and battery-only deployments covered under an 8x5 next-business-day Smart Net Total service level. CON-SSSNT-P8ZK90Z1 applies to the worldwide Cisco 840 phone and battery-only solution and identifies the support entitlement rather than a phone or battery shipment. It suits installations where business-hours support coverage aligns with the operational schedule of the voice endpoint estate. The 8x5 designation defines service availability during standard business hours on five days each week. Next-business-day service provides the response tier named by this SKU for the covered solution. This makes the service appropriate where an overnight response window is acceptable and continuous, around-the-clock coverage is not required. This specific entitlement is differentiated by its Cisco 840 compatibility, worldwide phone-and-battery-only scope, and 8x5 next-business-day service characteristic. Match the covered Cisco 840 configuration to the service requirement before assigning coverage. The SKU is intended for the phone and battery-only solution described here, allowing administrators to maintain the support level associated with that endpoint configuration without changing the installed hardware.
