Cisco Systems OL-31454-01 Manual De Usuario

 summarizes typical WAN and LAN connections for Cisco CGR 2010 routers. The connections 

summarized here are also described in detail in 

Cisco Modular Access Router Cable Specifications

This section explains the different ports and adapter pinouts available for the Cisco CGR 2010 router.

The console and auxiliary ports on Cisco IOS® routers are asynchronous serial ports. The console port 
and the auxiliary port are configured as data terminal equipment (DTE). For Cisco 2000 Series Routers, 
the console and auxiliary ports both use RJ-45 connectors. Adapters are available for connections to PC 
terminals, modems, or other external communications equipment.
