NM-16A Use Case
Out-of-Band Management for Enterprise Network Resilience
In a global enterprise with distributed data centers, IT teams deploy the NM-16A 16-port Asynchronous Module on Cisco routers to establish dedicated modem links for out-of-band (OOB) access. When primary IP paths fail, administrators maintain secure, uninterrupted control via asynchronous serial lines—ensuring faster mean-time-to-repair (MTTR), higher network availability, and compliance with enterprise SLAs.
Legacy Device Integration in Industrial IoT Environments
A manufacturing plant leverages the Cisco NM-16A 16-port Asynchronous Module to connect legacy PLCs and serial-based sensors directly to its core network. This modular approach preserves existing automation assets, accelerates IIoT integration, and reduces CapEx by eliminating expensive protocol converters—delivering seamless data flow, centralized monitoring, and improved operational efficiency.
SCADA and Telemetry Data Aggregation for Utility Networks
A regional utility company uses Cisco routers equipped with the NM-16A Asynchronous Module to aggregate serial telemetry from remote RTUs and SCADA endpoints. By consolidating up to 16 asynchronous links on a single chassis, operations teams achieve real-time monitoring, faster fault detection, and secure data transport over MPLS—optimizing grid reliability and reducing maintenance costs.
