Description

The ISR 4351 is a modular branch-office router from the Cisco ISR 4000 family, built for medium to large branch sites that need a converged WAN edge. It handles secure WAN and VPN connectivity, Catalyst SD-WAN, an on-site voice gateway, SIP trunking and Cisco Unified Border Element (CUBE) services on a single IOS XE platform.

This ISR4351-VSEC/K9 is the UC + Security bundle with a PVDM4-64 voice DSP module. It provides 3 onboard 10/100/1000 WAN/LAN ports, available as RJ-45 or SFP-based combo ports, plus 3 NIM slots, 2 single-wide SM-X slots and 1 double-wide SM-X slot for modular I/O. Aggregate throughput is 200 Mbps by default and can be raised to 400 Mbps with the Performance licence, or to over 2 Gbps CEF-only with the Boost licence. Memory is 4 GB DRAM and 4 GB flash by default, expandable to 16 GB of each. The VSEC bundle covers the Unified Communications and Security technology packages on the universal IOS XE image.

The PVDM4-64 sits in the onboard ISC slot and supports high-density voice DSP workloads. The chassis is 2RU with a 19-inch rack-mount kit and an internal AC power supply, with a PoE-capable supply available as an option.
