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.


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.


  • 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.



  •  Operator consoles communicate with the PCx system via console interface cards and console audio cards. The console interface card provides the mechanism by which the console communicates with the switch. The console audio card supports the audio portion of the console's operation with isolation, filtration, amplification and compression capabilities.

  • Console Configurations
    A variety of console configurations are available with the PCx system. Typical console hardware consists of a fully equipped Pentium PC, a color SVGA monitor, a Penta PCx interface and associated audio components.

  • Penta’s NTConsole™ Dispatcher Workstation integrates radio, telephone, and other voice communications into an easy to use, user configurable graphical interface.  Available for Windows™, Unix™, and Linux™, NTConsole ™ provides one touch placement of outbound calls and functions such as caller ID, Radio ANI, conference, patch, call transfer, hold, SQL based phone books, channel select, and console access to Nextel™ and iDEN networks.  Penta’s consoles utilize standard TCP/IP networks and work with Penta’s PCx™, MNx™ and SLx™ Integrated Communications Systems.  NTConsole™ is available for touchscreen, mouse, and keyboard operation.

  • 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.

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).
