Cisco 3900 Series
Modularity Features and Benefits
The Cisco 3900 Series provides significantly enhanced modular capabilities while maintaining investment
protection for customers. Most of the modules available on previous generations
of Cisco routers, such as the Cisco 3800 Series Integrated Services Routers, are supported on the Cisco
3900 Series. Additionally, modules used on the Cisco 3900 Series can easily be supported on other routers
in the Cisco Integrated Services Router portfolio to provide maximum investment protection.
Taking advantage of common interface cards across a network greatly reduces the complexity of managing
inventory requirements, implementing large network rollouts, and maintaining configurations across a variety
of branch-office sizes.
A complete list of supported modules, including a list of supported SFPs for the Cisco 3900 Series, is

Architectural Features Description
Cisco Services • Both the Cisco 3925 and Cisco 3945 offer a field-replaceable Services
Performance Engine (SPE) Performance Engine (SPE)-an option available on the Cisco 3900 Series
only. The SPE is a modular motherboard that will be upgradable with
higher-performance engines developed in the future.
• This engine protects your initial investment in the Cisco 3900 platform for
a longer time period and scales router performance as your network and
branch-office needs grow.
• A service module slot replaces the network module and the extension
module for voice/fax (EVM) slots and is offered on Cisco 3925, 3945
Integrated Services Routers.
Cisco Service Module
• Each service-module slot offers high data-throughput capability:
- Up to 4 Gbps aggregate toward the router processor
- Up to 2 Gbps aggregate to other module slots over the MGF
• Service module (SM) slots are highly flexible with support for
double-wide service modules (SM-D's), which are Service Modules
that require two SM slots. SM-Ds in the Cisco 3925 and 3945 provide
flexibility for higher-density modules.
• Service-module slots provide twice the power capabilities relative to
the network-module slots, allowing flexibility for higher-scale and better-
performance modules.
• An adapter module enables backward compatibility with existing network
modules, enhanced network modules ((NMEs), and EVMs.
• Power to service-module slots can be managed by extensions
similar to the Cisco EnergyWise framework, so your organization can
reduce energy consumption in your network infrastructure. Full Cisco
EnergyWise support will be available in future software releases.

Architectural Features Description
Cisco Enhanced High • The EHWIC slot replaces the high-speed WAN interface card (HWIC)
Speed WAN Interface Card slot and can natively support HWIC, WAN interface cards (WICs), voice
interface cards (VICs), and voice/WAN interface cards (VWIC).
(EHWIC)
• Four integrated EHWIC slots on the Cisco 3925 and 3945 allow for more
flexible configurations.
• Each HWIC slot offers high-data-throughput capability:
- Up to 1.6 Gbps aggregate toward the router processor
- Up to 2 Gbps aggregate to other module slots over the MGF
• Flexibility to support doublewide modules is enabled by combining
two EHWIC slots. Up to 2 doublewide HWIC (HWIC-D) modules
are supported.
Cisco Internal Services • A single ISM slot provides flexibility to integrate intelligent services
Module (ISM) modules that do not require interface connections.
• Each ISM slot offers high-data-throughput capability:
- Up to 4 Gbps aggregate toward the router processor
- Up to 2 Gbps aggregate to other module slots over the MGF
• The ISM replaces the AIM slot; existing AIM modules are not supported
in the ISM slot.
• Power to ISM slots can be managed by extensions similar to the Cisco
EnergyWise framework, so your organization can reduce energy
consumption in your network infrastructure. Full EnergyWise support will
be available in future software releases.
Cisco High-Density • PVDM3 slots natively support PVDM3 modules, providing support for
Packet Voice Digital richer density for rich-media voice and video.
Signal Processor (DSP)
• Each PVDM3 slot connects back to the system architecture through a
Module (PVDM3) Slots on
2-Gbps aggregate link through the MGF.
Motherboard
• Investment protection for PVDM2 modules is supported through an
adapter module.
• Power to the PVDM slots can be managed by extensions similar to the
Cisco EnergyWise framework, so your organization can reduce energy
consumption in your network infrastructure. Full EnergyWise support will
be available in future software releases.
• Two external Compact Flash slots are available on the Cisco 3900 Series
Compact Flash Slots Integrated Services Routers. Each slot can support high-speed storage
densities upgradable to 4 GB in density.
• Two high-speed USB 2.0 ports are supported. The USB ports support
USB 2.0 Ports
secure token capabilities and storage
