NETWORK EXAMPLE
Figure 1 above shows the Cisco 3800 Series routers converge voice, video, and data across a secure IPsec
VPN network with high-quality, reliable performance. DMVPN creates tunnels on-the-fly based on user
traffic. V3PN functionality provides QoS, multiprotocol, ease of provisioning, and secure connectivity.
Deploy the Cisco 3800 Series when you need:
• The highest performance and densities for
concurrent data, security, voice, and advanced
services with headroom for growth
• Higher availability and resiliency with OIR,
redundant system, and inline power options
• Higher WAN or voice densities with an
additional (fourth) HWIC
• Low density (up to 18 ports), integrated 10/100
switching with PoE support; up to 48 ports
with Cisco Inline Power
• Efficient, robust Error Correction Code (ECC)
DDR SDRAM memory to detect and correct
SDRAM errors without user intervention
• Integrated security services as part of Cisco
Self Defending Network, which enable
network device protection, threat defense,
secure connectivity, and endpoint protection
and control
• Integrated PVDMs, industry-leading call
processing and autoattendant solutions, and
high-density voice cards and modules that
speed IP Communications and give customers
a choice of telephony interface devices
• Advanced management for security, routing,
QoS, and switching services with Cisco Router
and Security Device Manager (SDM) 2.0
• Secure integrated call processing, voice mail,
flexible telephony interfaces, redundancy for
centralized call processing, with robust DSP
support, including local call conforming and
transcoding

Cisco 3800 Series Features Cisco 3825 Cisco 3845
Network module slots—These slots can accommodate
standard network module, NME, and NME-X slots. The NME
has the same form factor as the standard network module.
The EVM-HD is supported. The NME-X, when available, will
have a wider form factor than the NME. Two side-by-side
NME slots can be combined to accommodate one NMD or,
when available, a NME-XD.
