Eliminate the need for dedicated lines with the LS-4x4 line scanner! 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. 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. Applications Eliminate dedicated lines for...
