“Second generation ISRs feature an innovative multigigabit fabric (MGF) that allows for efficient module-to-module communication, enabling tighter services interactions across modules while reducing the overhead on the route processor.”
“The Cisco ISR G2 router chassis can be field upgraded with a number of hardware and software enhancements.
Among the hardware upgrades, four major categories include the following:
Enhanced High Speed Wan Interface Cards, known as EHWICs
The EHWIC slot provides a small form fact upgrade slot that supports the installation of HWICs, EHWICS, WAN interface cards, voice interface cards, and voice/WAN interface cards.
Internal Service Modules, known as ISMs:
A single ISM slot provides flexibility to integrate intelligent service modules on an internal slot within the chassis
Service Modules, known as SMs:
The Service Module slot provides a larger form factor upgrade path than the EHWIC and supports a range of different module sizes. The service module slot replaces the network module and the extension module for voice/fax slots used on previous generation ISRs
And finally Packet Voice Data Module 3, known as PVDM3:
PVDM3 slots natively support PVDM3 modules, providing digital signal processing support for rich-media voice and video
