Introduction
Cisco 3800 series integrated services routers are part of a new generation of routers that incorporate
high-performance integrated data, voice, video, and Virtual Private Network (VPN) capability. They are
designed for branch office installations that need integrated low-density switching, security, voice, IP
telephony, video, content networking, and concurrent applications.
Two routers in the Cisco 3800 series are the Cisco 3825 router and the Cisco 3845 router. Their features
include:
• Two built-in 1000BASE-T Gigabit Ethernet ports with RJ-45 connectors for shielded twisted pair.
One of these ports provides a slot for an optional small-form-factor pluggable (SFP) module.
• Hardware-based VPN encryption acceleration.
• Modular design that enables you to add a wide variety of LAN and WAN ports with interchangeable
network modules and interface cards.
The Cisco 3825 router provides two slots for network modules. The lower network module slot of this
router can hold a single-wide or extended single-wide network module. The upper slot of the Cisco 3825
router can hold a single-wide, extended single-wide, double-wide, or extended double-wide network
module.
The Cisco 3845 router provides four slots for network modules. Each slot can hold a single-wide or
extended single-wide network module. Slots can be combined in pairs to hold a double-wide or extended
double-wide network module.
The Cisco 3825 router and the Cisco 3845 router each provide four interface card slots. Each slot can
hold a single-wide WAN interface card (WIC), voice interface card (VIC), voice/data T1/E1 WAN
interface card (VWIC), or high-speed WAN interface card (HWIC). Slots can be combined in pairs to
hold a double-wide HWIC.
Advanced integration modules (AIMs) and packet voice data modules (PVDMs) install into connectors
on the router motherboard. AIMs provide hardware-based support for additional features. PVDMs are
digital signal processor (DSP) SIMMs that provide voice support. The Cisco 3825 router and the
Cisco 3845 router can each accommodate two AIMs and four PVDMs.
