NM-4T Use Case
Remote Branch WAN Connectivity with Cisco NM-4T-4-Port Serial Module
In a multi-site financial services environment, IT teams deploy the Cisco NM-4T-4-Port Serial Network Module on aggregation routers to terminate four independent T1/E1 serial links. This configuration ensures deterministic, high-throughput WAN connectivity for core transaction systems, enabling 99.99% uptime and sub-50 ms latency between headquarters and remote branches. Benefit: Achieve secure, resilient data transport that supports real-time trading and compliance reporting with minimal operational overhead.
Legacy Device Integration for Industrial Control Networks
A manufacturing OEM leverages the NM-4T-4-Port Serial Module to bridge legacy PLCs, SCADA controllers, and CNC machines into its IP backbone. By consolidating up to four 2-wire/4-wire serial endpoints on a single Cisco router slot, the company standardizes management via IOS, enforces ACLs and QoS policies, and eliminates multiple serial-to-Ethernet gateways. Benefit: Simplify network topology, reduce hardware footprint by 40%, and accelerate troubleshooting while preserving OT connectivity and security.
High-Availability Failover for Service Provider Edge Routers
A global service provider implements the Cisco NM-4T-4-Port Serial Module in dual edge routers to support synchronous backup circuits for MPLS and Frame Relay customers. Integrated with Cisco IOS dynamic routing and object-tracking, the setup automatically switches traffic across any of the four serial ports in under 200 ms when primary links degrade. Benefit: Deliver carrier-grade redundancy and service continuity, reducing SLA violations and maintaining customer confidence in 24/7 critical communications.
