CHAPTER 4: Operation and Troubleshooting
If your LineShare 1 x 4 system is installed correctly, it should operate
continuously without user intervention. As different attached devices access
the line, the port-activity LEDs on the LineShare 1 x 4 units will show which
one is using the line at any given time. All other attached devices will be
excluded from the line and be sent a busy signal while any attached device,
or any other device on the same line, is using the line.
If you ever have any trouble with your LineShare 1 x 4 system, follow the
instructions in the rest of this chapter.
