When a device, such as a modem, attached to a device port needs access to a
telephone line, the LS-4x4 will instantly scan for an open line starting from the last line
to the first line. When the LS-4x4 detects an open line, that line is routed to the device
port, while incoming calls may also be routed to a corresponding device port. If no
lines are available, a fast busy tone will be returned.

Each LS-4x4 will accept one to four
telephone lines and one to four
devices. Depending on the number of
line scanners cascaded, 1, 2, 3,
4...8...12 or more modems, credit card
readers, fax machines, etc., may share
one to four telephone lines or analog
PABX/KSU stations.
