Compare Cisco (NM-1GE) Expansion Module to Cisco (NM-16A/S) Expansion Module

The single-port Cisco Gigabit Ethernet Network Module (part number NM-1GE) provides Gigabit Ethernet optical and copper connectivity for access routers. The module is supported by the Cisco 2691, Cisco 3660, Cisco 3725, and Cisco 3745 series routers. This network module has one gigabit interface converter (GBIC) slot to carry any standard copper or optical Cisco. The flexibility to use different GBICs allows for making a choice depending on various factors, such as distance, cost, existing infrastructure, future expansion plans, and requirements.??The Cisco Gigabit Ethernet Network Module enables branch offices to cost-effectively utilize high-speed uplinks in a variety of environments. The enhanced performance allows customers to enable new applications and services as well as providing greater capacity for existing inter-VLAN routing and bridging capabilities. Additionally, branch offices will now have the opportunity to connect to metropolitan-area networks (MANs). Cisco IOS Sof... Less

The NM-16A/S combines the rich multi-protocol support of the NM-4A/S and NM-8A/S with higher densities to provide compelling price-per-port solutions for networking applications. In addition to the features of the NM-4A/S and NM-8A/S, the NM-16A/S adds EIA-530A support, and support for physical lead manipulation in the IOS configuration. Lead manipulation allows the user to configure the router to ignore input signals, view the state of input signals, and to monitor the transitions of input signals. Less
