Cisco ISR4331 Router (ISR4331-V/K9)
The Cisco ISR4331-V/K9 is a branch-level enterprise router designed for converged data and voice services. With aggregate throughput from 100Mbps to 300Mbps, it suits SMEs and distributed enterprises that need scalable performance as bandwidth grows. Three onboard 10/100/1000 WAN/LAN ports and dual SFP-based interfaces enable flexible fiber or copper uplinks across Asian, European, African, and North American networks. Integrated NIM and service-module slots support security, WAN optimization, and voice bundles, helping distributors, VARs, and end users deploy secure, manageable multiservice connectivity.
