The PLS is designed for applications that require automatic routing of Cat5 10/100 Base-T signals between a common jack and an "A" and "B" jack. The PLS is also ideal for switching RS-232, DSL, RS-422/485, or telephone lines.

Remote Switching

This versatile A/B switching system can be controlled over any TCP/IP network using standard Telnet, or out-of-band using an external modem and basic VT100 type terminal emulation. Each of the three A/B circuits can be switched via code command or locally via manual switches from the front panel. Other intelligent features include; password, site ID, connector labels, status display and more.

Monitor Mode

The Monitor Mode allows the PLS to monitor an external RS-232 or contact closure input and automatically switch selected A/B paths. Definable parameters allow the user to select the monitor signal trigger duration, circuits to switch, and the option to return to its original A/B position.

Security Features

Address-specific IP security masks prevent unauthorized sources from accessing the PLS menu through the network. The PLS provides two levels of operational passwords; the system administrator level, which allows access to all configuration and switching functions, and the user level, which only allows switching of the circuits.
