Also include a console port, integrated dual 10-/100-/1000-Mbps ports, two AIM slots, four PVDM slots, and two USB 1.1 ports.
Support 802.11a/b/g wireless LAN standards.
Add optional modules for T1 trunking, voice and modem communications, security, data compression, high-speed networking and switching, and more. To specify modules, contact our FREE Tech Support.
Both routers include embedded VPN, 64 MB Compact Flash, 256 MB DDR SDRAM, and Cisco Router and Security Device Manager (SDM) for simplified management.
The 3845 model also includes a built-in redundant power supply (RPS), ensuring reliable operation. (An external RPS is available for the 3825.)
Take advantage of converged business services while minimizing the cost and complexity of network upgrades with these modular, multiservice routers from Cisco.
Ideal for users who demand a single, resilient system that delivers best-in-class routing for data, security, and voice services, Cisco 3800 Series Routers give you more power and options for your evolving network—from your corporate headquarters to your branch offices. Because the routers use modular components, you can easily change network interfaces without having to upgrade your entire branch-office network.
Flexibility through modularity.
The routers feature interface options for add-on modules (for a full list of those supported, contact our FREE Tech Support). Each 800 Series network module slot can accommodate standard network modules, enhanced network modules (NME), the high-density voice/fax extension module (EVM-HD), or the enhanced extended network module (NME-X).
You can also combine two side-by-side NME slots to hold a single double-wide network module (NMD) or, when available, a double-wide NME-X (NME-XD).
The routers also have four HWIC slots, which can be fitted with WICs, VICs, and voice and WAN interface cards (VWICs). Or, if you like, use two side-by-side HWIC slots to seat one double-wide HWIC (HWIC-D).
In addition, the routers contain a fixed SFP slot, dual AIM slots, and four packet voice/fax digital signal processor (DSP) module (PVDM2) slots.
Scalable voice capabilities.
The embedded DSP slots make each Cisco 3800 Series Router a voice-ready system. In fact, the 3800 Series delivers the highest digital and analog voice densities available. Just add the voice capabilities you need, scaling the routers to fit the size of your office or enterprise voice requirements.
For additional capabilities, such as call processing, auto attendant, and voice mail, use the routers with Cisco’s award-winning IP Communications Express software, which supports up to 240 Cisco IP phone users.
The routers also support Cisco Survivable Remote Site Telephony (SRST) for up to 720 Cisco IP phone users. This provides call-processing functionality that keeps voice service up and running should the router lose its connection to Cisco CME.
10/100/1000 connectivity, plus PoE and WLAN support.
On the LAN side, the routers feature dual 10-/100-/1000-Mbps connectors for linking to Ethernet, Fast Ethernet, or Gigabit Ethernet networks. These ports give you the bandwidth requirements for multiple high-speed Ethernet interfaces, autosense the speed and autonegotiate to the duplex mode of the connected network, and support 802.1Q VLAN trunking protocols and time-division multiplexing (TDM) interconnections.
You can even use one of the 10/100/1000 ports to plug in a Small-form Factor Pluggable (SFP) module to uplink to a speedy Gigabit Ethernet fiber optic backbone (NOTE: Cisco manufactured optical transceiver models supported only).
And because the routers support 802.3af Power over Ethernet (PoE) and Cisco proprietary inline power, you can power IP phones, Cisco Aironet® access points, and other compliant equipment through the UTP cabling itself—great for office or wireless applications short on electrical outlets.
The 3800 Series Routers support a number of wireless connectivity options. For WLAN communications, you can add an 802.11b/f or 802.11a/b/g HWIC access point interface card, a WLAN controller to manage up to six WLAN access points, and telephony support for WLAN IP phones.
Embedded and upgradable security
Supporting all the benefits of the Cisco Intrusion Prevention System (IPS), the Cisco 3800 Series Routers offer secure connections and can be used to establish up to 2500 VPN tunnels. They support MPLS IP security (IPSec) VPNs and feature embedded VPN encryption acceleration (with the option to add advanced encryption, if needed, for additional performance and tunnel scalability, plus hardware-assisted compression with IPPCP).
By using the routers with the Cisco IOS Software Advanced Security package, you can enable IPSec and AES, 3DES, and MPLS VPNs, as well as the Cisco IOS Firewall, which is a stateful-inspection firewall option that offers an ideal single-box security and routing solution for protecting the WAN entry point into your network.
And, through the modular slots, you can also add an IDS network module to inspect traffic for unauthorized or malicious activity (such as hacker or denial-of-service attacks), as well as a content-engine network module, which delivers Application Layer services for Web application acceleration, business video streaming, software distribution, and URL filtering.

Calls through connected Cisco IP phones remain secure, too. That’s because the routers, operating as a platform for integrated IP telephony, offer standards-based, secure media and signaling authentication and encryption from IP phone to IP phone, or IP phone to analog phone or public switched telephone network (PSTN) gateway.
