CISCO3925-K9

Modularity Features and Benefits:

The Cisco 3900 Series provides significantly enhanced modular capabilities while maintaining investment protection for customers. 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.

Architectural Features

Benefits

Cisco Services Performance Engine (SPE)

• The Cisco 3900 Series offers field-replaceable SPEs.
• These SPEs allow you to protect your initial investment in the Cisco 3900 platform for a longer time period and scale router performance as your network and branch-office needs grow.

Cisco Services Module

 

fig 4
fig 5
• A service-module slot replaces the network module and the extension module for voice and fax (EVM) slots and is offered on Cisco 3900 Integrated Services Routers.
• 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 slots are highly flexible, with support for doublewide service modules, which are service modules that require two service-module slots. Doublewide service modules 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.
• You can manage power to service-module slots 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.

Cisco Enhanced High Speed WAN Interface Card (EHWIC)

fig 6
• The EHWIC slot replaces the high-speed WAN interface card (HWIC) slot and can natively support HWICs, WAN interface cards (WICs), voice interface cards (VICs), and voice/WAN interface cards (VWICs).
• Three integrated EHWIC slots on the Cisco 3945E and Cisco 3925E or four integrated EHWIC slots on the Cisco 3945 and Cisco 3925 allow for 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 High-Density Packet Voice Digital Signal Processor (DSP) Module (PVDM3) Slots on Motherboard

fig 8
• PVDM3 slots natively support PVDM3 modules, providing support for richer density for rich-media voice and video.
• Each PVDM3 slot connects back to the system architecture through a 2-Gbps aggregate link through the MGF.
• Investment protection for PVDM2 modules is supported through an adapter module.
• You can manage power to the PVDM slots 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.
