PRP Auxiliary and Console Ports
The auxiliary and console ports on the PRP are EIA/TIA-232 (also known as
RS-232) asynchronous serial ports. These ports connect external devices to
monitor and manage the system.
• The auxiliary port—A (male) plug that provides a data terminal equipment
(DTE) interface. The auxiliary port supports flow control and is often used to
connect a modem, a channel service unit (CSU), or other optional equipment
for Telnet management.
• The console port—A (female) receptacle that provides a data
circuit-terminating equipment (DCE) interface for connecting a console
terminal.
