Subnetwork Craft Terminal (SCT) is a specialized software management interface used by field technicians and network engineers to configure, monitor, and troubleshoot individual elements within a telecommunications transport network.
Craft Port (RS-232/EIA-232): The traditional serial interface found on legacy transmission equipment (PDH/SDH). It requires a physical serial cable connection.
Ethernet Management Port: The standard for modern equipment. The technician connects via Ethernet cable to a dedicated management interface on the device.
Protocols Supported:
Cloud-native: SCT controller runs in Kubernetes; agents as DaemonSets; integrate with CNI and service mesh.
Hybrid/Edge: central controller in cloud, edge SCT instances run on-site with local control and push-sync state.
On-prem Monolith: single SCT appliance for small data centers handling all control and telemetry.
