ISR Modules
Benefits
Cisco Enhanced High-Speed
WAN Interface Card (EHWIC)
● The EHWIC slot provides enhancements to the prior generation’s high-speed WAN interface card
(HWIC) slots while provide maximum investment protection by natively supporting HWICs, WAN
interface cards (WICs), voice interface cards (VICs), and voice/WAN interface cards (VWICs).
● Four integrated EHWIC slots on the Cisco 2901, 2911, 2921, and 2951 allow for more flexible
configurations.
● Each HWIC slot offers high-data-throughput capability:
◦ Up to 1.6 Gbps aggregate toward the route processor.
◦ Up to 2 Gbps aggregate to other module slots over the MGF.
● Flexibility to support double-wide modules is enabled by combining two EHWIC slots. Up to 2
doublewide HWIC (HWIC-D) modules are supported.
Cisco Internal Services Module
(ISM)
● A single ISM slot provides flexibility to integrate intelligent service modules on an internal slot within the
chassis
● Each ISM slot offers high-data-throughput capability:
◦ Up to 4 Gbps aggregate toward the route 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 Packet Voice
Digital Signal Processor (DSP)
Module (PVDM3) Slots on
Motherboard
● 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.
● 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.
Compact Flash Slots
● Two external Compact Flash slots are available on the Cisco 2900 Series Integrated Services Routers.
Each slot can support high-speed storage densities upgradeable to 4 GB in density.
USB 2.0 Ports
● Two high-speed USB 2.0 ports are supported. The USB ports enable secure token capabilities and
storage.
Cisco IOS Software
Cisco 2900 Series Integrated Services Routers deliver innovative technologies running on industry-leading Cisco
IOS Software. Developed for wide deployment in the world's most demanding enterprise, access, and service
provider networks, the Integrated Services Routers Generation 2 platforms are supported on Cisco IOS Software
releases 15M&T. Release 15.0(1)M is available immediately and provides support for a comprehensive portfolio of
Cisco technologies, including the functionality and features delivered in releases 12.4 and 12.4T. New innovations
in 15.0(1)M span multiple technology areas, including security, voice, high availability, IP Routing and Multicast,
quality of service (QoS), IP Mobility, Multiprotocol Label Switching (MPLS), VPNs, and embedded management.
Cisco IOS Software Licensing and Packaging
A single Cisco IOS Universal image encompassing all IOS technology feature sets is delivered with the platforms.
You can enable advanced features by activating a software license on the Universal image. In previous
generations of access routers, these feature sets required you to download a new software image. Technology
packages and feature licenses, enabled through the Cisco software licensing infrastructure, simplify software
delivery and decrease the operational costs of deploying new features.
