The actual IC chip interface will depend on the bus interfacing to the Cng board. A motherboard manufacturer can choose to provide audionetworkingor modem functionality in any combination on a CNR card. The board size and pinout are also defined in the specification for the ATX series of motherboard form factor.

Each Riser standard has a listing on this page which may provide additional technical information about the standard. Refer to the PC Interface Bus page for a complete listing of computer buses. Type A and Type B, each with different pin assignments. So Riser implementations are only seen as deliverables from computer manufacturers, and not as up-grade cards in commercial stores.

The result was that, although some motherboards included an AMR slot, very few AMR-compatible cards were ccard developed and those that were achieved only limited distribution.

While a consumer would not up-grade using a Riser slot, opting for a PCI slot implementation instead. Views Read Edit View history.

Reading the News groups it appears many people are surprised to find a riser slot and have no idea what it is for. The modem is a WinModem.

Nearly everything inside a PC is designed to be user-installable. AMR slot Intel developed the AMR slot to provide an easy, standardized way to integrate modem and audio functions into finished systems at minimal cost, but OEM system builders ignored it in droves.

AMR vs. CNR, Intel’s new standard –

Communications and networking riser CNR is a slot found on certain PC motherboards and used for specialized networking, audio, and telephony equipment. In most cases driver IC’s will be listed on one of those pages. Communication and Networking Riser: The AT Form Card page provides the pinout for this interface.

Get modeem access to videos, live online training, learning paths, books, tutorials, and more.

Many see them as dard cost cards using a slot that could have been a spare PCI slot. Physically, a CNR slot has two rows of 30 pins, with two possible pin configurations: However; many people are more concerned about cost with out regard for the number of PCI expansion slots, or whether the function is performed by the processor or some expansion card.

Although their presence on many recent motherboards intrigues some upgraders, these slots were never intended as general-purpose expansion slots. For all other IC functions use the Components Icon below. Retrieved from ” https: This page was last edited on 11 Augustat This resulted in a quicker production-to-market time for new motherboards, and allowed mass-production of CNR cards to be used on multiple motherboards.

Intel developed the AMR slot to provide an easy, standardized way to integrate modem and audio functions into modm systems at minimal cost, but OEM system builders ignored it in droves.
