Serial Interface Cards
Serial WAN Interface Card LEDs
Each serial WIC has one LED, labeled CONN for each port, which lights when the serial port is
connected. When the port is in DTE mode, the CONN LED indicates that Data Send Ready (DSR), Data
Carrier Detect (DCD), and Clear To Send (CTS) have been detected. When the port is in DCE mode, it
indicates that Data Terminal Ready (DTR) and Ready To Send (RTS) have been detected.
