PCx Communications
Control System-
|
 Designed
for dispatching, public address and other communications management
applications, Penta Corporation's PCx Communications Control System
integrates the control of radios, telephones, intercoms, PBX circuits,
microwave channels, fiber optic lines and consoles into a single, affordable
system. Custom software can facilitate networking, multi-tasking, voter
steering and a host of other specific system requirements.
Overview
The PCX Communications Control System is based on Penta's
proprietary network switch, featuring user- programmability, redundancy and
no single point-of-failure. The non-blocking switch can control up to 512
lines and consoles, and the modular units can be networked to consolidate
operations over large areas, providing operations of any size. Penta's
Windows-based control consoles provide touch-screen, mouse, trackball or
keyboard control over any or all circuits connected to the network switch.
The password-protected consoles allow operators to access radios, telephones
and other consoles and to conference an unlimited number of circuits. |
 Features
-
Integrates the control of all types of electronic
communication.
-
Offers unlimited patching and conferencing
capabilities.
-
Employs a non-blocking audio switch matrix design.
-
Redundant processors and dual power supplies assure
uninterrupted system operation.
-
Modular architecture provides for the integration of
virtually any number of lines or consoles.
-
Custom software can facilitate networking,
multi-tasking, voter steering and other specific system requirements.
-
Operator consoles are PC-based units available with
touch-screen, mouse, trackball or keyboard control.
-
Console software runs in both DOS and Windows
environments. Applications Networking, multi-tasking and interfacing to
other subsystems (such as ATS, CAD, CTC, GPS and SCADA systems) are
possible with the PCx system.
-
Interface Cards Microprocessor-based line interface
cards provide the interface between the PCx system and most types of two-
and four-wire communications circuits.
Only one type of line card is used in the system; no special interface
boards or control modules are required to communicate with various types
of lines.
Additionally, user programmability and configurability have been designed
into the card to permit field adjustment of signaling and line
designations.
| Other unique features of the
line interface card include: |
|
-
Adjustable transmit and receive levels,
-
DTMF in and out,
-
transformer isolation,
-
voice activity detection (VOX)and,
-
receive-line compression.
- Single tone, dual tone, in/out.
|
-
The line card includes options for:
-
a modem,
-
a logging recorder output,
-
a digital front end,
-
and other special application modules.

The operator interfaces with the console
via touch-screen, mouse, trackball or keyboard provided with each
console position. Screen presentations are well-organized to
facilitate quick access to all functions.
-
Penta console software is
Windows-compatible to provide a level of systems integration
unattainable with any other communications control system on the
market. Desktop, phone-type consoles are also available with the PCx
system.
Penta has designed the systems for
maximum flexibility so customers receive the most efficiently integrated
packages available. The company has networked geographically diverse
multiple PCx systems together, written console software to run in tandem
with other subsystem programs, and combined dispatching and public
address control functions in the same system. |

Protocols
The PCx system is continually evolving to incorporate
new and innovative technologies. Operators can now create forms and generate
faxes from their consoles -- without exiting the Penta software. They can
send and receive data from the consoles (via e-mail) and on-line
communications services. Data also can be employed to control radios (using
ANI and other selective call protocols).
