Cisco Systems 12006 Manual De Usuario

This section provides the information for connecting console terminals and other 
auxiliary devices to the console and auxiliary ports on the router. Both Data Set 
Ready (DSR) and Data Carrier Detect (DCD) signals are active when the system 
is running. The console port does not support modem control or hardware flow 
control. GRP ports are discussed below. PRP ports are discussed in the 

.

This section provides connection equipment and pin designation information for 
the console and auxiliary ports on the Gigabit Route Processor (GRP).

To maintain Class B, EMI compliance, shielded cables must be used on the 
console and auxiliary ports of the GRP= and GRP-B=. 

The GRP has two EIA/TIA-232 ports:

DCE DB-25 receptacle for connecting a console terminal 

DTE DB-25 plug for connecting other DTE devices

The DCE-mode console port is a DCE DB-25 receptacle used for connecting a 
console terminal, which you will need to configure the router. 

The DTE-mode auxiliary port is a DTE DB-25 plug for connecting a modem or 
other DCE device (such as a channel service unit/data service unit [CSU/DSU] or 
another router) to the router.

The console and auxiliary ports are asynchronous serial ports; any devices 
connected to these ports must be capable of asynchronous transmission. 
Asynchronous is the most common type of serial device; for example, most 
modems are asynchronous devices.
