Apply a 24x7x4-hour onsite service level to the Cisco ISR 1100 4-port router configuration with dual Gigabit Ethernet SFP interfaces. CON-NCH4P-C11214PK supports installations where router availability matters outside normal business hours and where onsite response must be measured in hours rather than the next business day. The 24x7x4OS designation expresses 24-hour, seven-day coverage with a four-hour onsite response target. Coverage is associated with the stated ISR 1100 router configuration, including its four-port design and dual Gigabit Ethernet SFP interfaces. This SKU represents a support service, not a router, SFP transceiver, or expansion hardware component. Use this service level for branch, retail, field, and distributed network locations that depend on the covered router for WAN access or local network connectivity. Its defining characteristic is the combination of continuous coverage and an onsite response target, making it appropriate where local technical intervention may be required outside standard support hours. Match the service to the stated router configuration and required response level before deployment.
