Western Telematic PLS-345 - Manual (Page 7)

1. Introduction
The PLS-345 Physical Layer Switch is a versatile A/B switching
system, which 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 on the instrument front panel. Other intelligent
features include password protected access to command mode
functions, site I.D. Message, connector labels, status displays
and more.
The PLS-345 is designed for applications that require automatic
routing of Cat5 10/100Base-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.
Monitor Mode
The Monitor Mode allows the PLS-345 to monitor an external
RS-232 line or contact closure input and automatically switch
selected A/B paths. Easily definable parameters allow the user
to select the monitor signal trigger duration, circuits to switch,
and the option to return circuits to their original A/B position.
Security Features
Address-specific IP security masks prevent unauthorized sources
from accessing the PLS-345 menu through the network. The
PLS-345 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-345 can be configured over the network, via modem, or
from a local PC or terminal connected to the unit's Console Port.
Easy to use commands let you assign a location name, set system
parameters, and view circuit status. Circuits can be switched
using numbers or names.
