The left digit shows the number of 8-port unit that configured (if continuous 8 ports
are considered as an 8-port unit) and the right digit shows the last port number
within an 8-port unit. For example, if “48” is displayed, it means that the last
accessible port is the eighth port of the fourth 8-port unit.
To see a particular port’s line status, you can keep pressing Module Button and
Channel (Port) Button till the desired port is shown on LED display, then look at the
seven indicators TxD, RxD, DTR, DSR, RTS, CTS, and DCD. This provides a
convenient diagnostic ways for Intellio C320Turbo Normally, DTR and RTS indicators
will light on when local port is opened while DSR and CTS indicators will light on
when remote port is opened. TxD indicator will light on if local port is transmitting
data and RxD indicator will light on if local port is receiving data (or remote port is
transmitting data). DCD indicator is mostly useful to detect phone line carrier when a
modem is connected to the port.
