2.6.5 CNR slot

The Communications and Networking Riser (CNR) slot supports interface

cards that integrates audio, modem, and network functionality.

The CNR specification supports interfaces including:

• Audio Codec ‘97 (AC ’97) - for audio and/or modem functions

• Local Area Network (LAN) - for networking functions

• Universal Serial Bus (USB) - for functions implemented in the USB

interface, and technologies such as broadband, DSL, and wireless

• System Management Bus (SMB) - for Plug-n-Play functionality

• Power - to provide the signals required for power management, and the

main power supplies to operate the CNR circuitry

The CNR is tagged to replace the current Audio Modem Riser (AMR) slot

because of its flexibility and added features. Also, the CNR slot does not

take up the motherboard space for one PCI slot because it is a shared

slot; rather, it provides you more options.
