Maintain a Cisco Webex Desk no-radio configuration under an 8x5xNBD CMB service designation. This service applies to the Webex Desk configuration named in the ordering description and carries ECDN service identification. The 8x5xNBD level indicates service availability during eight-hour, five-day coverage windows with next-business-day handling. CON-NCFDN-CS4SK9DE is a Cisco service ordering code rather than a Webex Desk hardware unit. It is intended for deployments using the no-radio Webex Desk configuration, helping administrators retain the service level associated with that endpoint. The no-radio designation is a material compatibility detail: this service is associated with that stated Webex Desk variant, not a general-purpose endpoint service description. The defining characteristics are the Cisco Webex Desk platform reference, no-radio configuration, CMB service designation, ECDN identifier, and 8x5xNBD coverage level. These details let engineers align the service code with the endpoint configuration already in use. The next-business-day designation differentiates this option from service levels that use other response or coverage schedules, while 8x5 limits the coverage window to standard business-day availability.
