Cisco CON-SSSNT-ONS155I1 8x5xNBD Support for OC3/STM1 | Service — CON-SSSNT-ONS155I1

Maintain continuity on OC3/STM1 optical links with Cisco solution support built for environments that cannot afford extended service interruption. This service package provides 8x5 coverage with next-business-day response, aligning support availability to standard business operations while preserving a clear escalation path for critical SFP-related issues. For teams running legacy transport or mixed-generation WAN infrastructure, the value is in predictable coverage and vendor-backed response when optics or interface modules need attention. It is a practical fit for organizations that still depend on OC3/STM1 connectivity for branch aggregation, carrier handoffs, or specialized network segments. Rather than absorbing the risk of ad hoc troubleshooting, this support offering gives procurement and operations a defined service boundary tied to the installed Cisco environment. Choose this support model when uptime matters, but 24x7 coverage is not required. It helps extend the useful life of deployed hardware while keeping support costs aligned to the service window your network actually needs.
