cisco
Enterprise-grade legacy 4-port serial expansion network module, engineered to deliver flexible WAN connectivity, synchronous routing, and legacy device integration for modular Cisco routers.
The NM-4T is an internal legacy enterprise-class 4-port serial network module designed to expand WAN connectivity across Cisco modular multi-service routers. Equipped with four high-density synchronous/asynchronous serial ports supporting DB60 connections, this module enables robust data transmission over traditional leased lines, Frame Relay networks, and X.25 configurations. Running at a maximum synchronous speed of up to 2.048 Mbps per port, it provides flexible data rate configurations and hardware-level line diagnostics, making it an essential option for legacy corporate offices requiring dedicated remote branch links, legacy hardware signaling, or back-to-back testing lab geometries.
