An ESCON Channel Port Adapter 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 ESCON Channel Port Adapter contains an ESCON I/O connector. The ESCON Channel Port Adapter is a high-bandwidth port adapter. A Fast Ethernet port adapter is an example of another type of high-speed port adapter. A single Cisco 7200 series router can support up to three high-speed port adapters.
