About the Cisco 1-, 2-, and 4-port Serial NIMs
The Cisco 1-, 2-, and 4-port Serial NIMs are multi-protocol synchronous serial network interface
modules (NIMs) supported on the Cisco 4400 Series ISRs. The Cisco 1-port, 2-port, and 4-port Serial
NIMs expand the capabilities of the router to provide connectivity for synchronous interfaces in a wide
range of applications including up to 8Mbps date rate for high speed high-level data link control
(HDLC). These capabilities can be utilized as Point-to-Point Cisco HDLC WAN interface or frame relay
interface. The Cisco 1-, 2-, and 4-port Serial NIMs have their own serial communication controllers
(SCC) and they do not rely on the host router for SCCs.
