The Cisco NCS 1001 (Figure 1) is a 1RU system that is capable of supporting up to three pluggable modules. The modules can be amplifiers or protection switch modules. The system reuses controller cards and power supplied from the NCS 1002. A 96-channel unprotected point-to-point or a protected point-to-DWDM line system can be implemented with one NCS 1001.
The system operates on a Linux kernel with the carrier-class 64-bit Cisco IOS XR Software in a Linux container (LxC) and XR system admin plane in a separate LxC. It encompasses a wide variety of features as well as a range of machine-to-machine APIs based on YANG models for ease of configuration and a telemetry agent for a pub-sub model of device monitoring and also provides an infrastructure for third-party applications.
