Maintain service continuity around the control plane that keeps optical transport infrastructure running. This Cisco next-business-day support offering is built for the NCS 2000 Transport Node Controller, helping teams reduce exposure when controller issues threaten provisioning, monitoring, or restoration workflows. For operators managing dense transport layers, support coverage matters as much as the hardware itself. Faster access to Cisco assistance can shorten troubleshooting cycles, simplify replacement planning, and reduce the operational drag that comes with waiting on standard response windows. That makes this offering a practical fit for networks where downtime carries real cost. Because it is aligned to the NCS 2000 controller platform, this support SKU is suited to organizations standardizing on Cisco optical transport infrastructure and looking to preserve service levels without overbuying broader coverage than they need.
