Communications and networking riser (CNR) is a slot found on certain personal computer motherboards and used for specialized networking, audio, or telephony equipment. A motherboard manufacturer may choose to provide such functionality in any combination on a CNR card.^[1] Introduced by Intel in 2000,^[2] CNR slots were once commonly found on Pentium III–class motherboards, but have since been phased out in favor of on-board or embedded components.^[3]
