The ATM interface processor (AIP) provides a single ATM network interface for Cisco 7000 series and Cisco 7500 series routers. The AIP provides a direct connection between the high-speed Cisco Extended Bus (CxBus and CyBus) and external ATM networks. A physical layer interface module (PLIM) on the AIP determines the type of ATM connection. There are no restrictions on slot locations or sequence; you can install an AIP in any available interface processor slot.
