Used Cisco WAN Serial Network Module

Part # NM-4T

Product Description: Cisco 2691, 3600, 3700, 3800 Series - 4-Port Sync Serial Network Module. The NM-4T serial network module has four synchronous serial interfaces. The network module supports a total full-duplex throughput of 8 megabits per second (Mbps), which can be realized over one port (at 8 Mbps) or across all four ports (at 2 Mbps on each port). The NM-4T module in any network environment delivers very low price per port and provides higher performance than comparable third-party solutions. For instance, a small or medium-sized Internet service provider (ISP) with high serial density requirements may find this solution very cost-effective per subscriber.
