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.

Table 1 lists the Cisco 1-, 2-, and 4-port Serial NIMs SKUs.
