Compare Cisco (PA-1C-P=) Expansion Module to Cisco (NM-1GE) Expansion Module

A Parallel Channel Port Adapter (PCPA) provides a single channel interface for Cisco 7200 series routers. In some situations, this interface can eliminate the need for a separate front-end processor (FEP). The PCPA contains a bus and tag (also called an original equipment manufacturer's interface (OEMI) and a parallel I/O interface) connector. Less

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
