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.

PLS-345 Application Diagram

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.

Easy to Configure, Easy to Use

The PLS can be configured over the network, via modem, or the local console port. Easy to use commands let you assign a location name, set system parameters and view circuit status. Circuits can be switched using circuit numbers or names.
