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.
