Cisco 3945 Integrated Services Router
Build a reliable, flexible network for your busy branch or office. The Cisco 3945 router brings routing, security, voice, and WAN connectivity together in one modular chassis, so you manage fewer devices. As a result, you cut cost and complexity. In addition, the slot-based design lets you add features as your business grows.
Why choose this router?
- Three Gigabit Ethernet ports: The onboard 10/100/1000 ports connect your LAN and WAN links without extra hardware.
- Four EHWIC slots: You can add WAN, switching, and voice cards, so you build the exact setup you need.
- Service module slots: Four service module slots also support extra applications and services.
- Voice-ready: Four DSP slots support voice services, which suits companies that run VoIP.
- Built-in security: Cisco IOS firewall, zone-based firewall, IPS, and content filtering protect your network, so you add fewer separate security boxes.
- Room to upgrade: It ships with 1GB DRAM and 256MB CompactFlash, and you can expand both later.
Where does this router fit in your network?
The Cisco 3945 router suits large branch offices, banks, schools, and companies with several sites. For example, you can use it to link branches over secure WAN connections, or to deliver voice and data from one device.
